Green Attic Insulation

We had Green Attic out to give us a quote for garage and attic space. Their Team 5 (Alex, Omar and Herbert) came out and worked for 2 days, non-stop. Alex discovered an area of mold in the attic that had not been seen before the quote. He took photos of every step of the remediation and showed them to us. He discussed needs for remediation and completed it right away. He spoke to us before each step and asked for approval. His team, Omar and Herbert worked as hard and long as any team we’ve ever had for past home improvements. Everything was taken care of by the end of day two. The team made sure that everything was spotless and clean before they left. I’d like to commend Alex, Omar and Herbert for their strong work ethic and genuine politeness. They were trained in a way that calls for excellence. I had a lot of contact with Tim, who came out for the original quote and he never tired of explaining procedures to us. We are so happy with the entire team of Green Attic professionals.

We had a verified raccoon in an enclosed attic space in the back of our house for 10 days. We were concerned about possible waste left behind and wanted the attic spaced inspected via a camera scope through the roof. When I reached out to Green Attic, I was clear that the attic space was not accessible from inside the house and would need to be accessed through a roof vent. The people on the phone during my initial call said that wouldn't be an issue. When the tech showed up, he said he said he could not perform the inspection through the roof.

Luis and truck #5 did an outstanding job! They were professional and very swift in completing the job. James, the owner was great to deal with and followed up along the way. I really appreciate Luis and his crew’s attention to keeping everything tidy and how well they cleaned up each day and at the conclusion of the job.

TLDR: We paid Green Attic $45,164.20 for them to do significant damage to our home and they refused to fix or help pay for all the damage and then threatened to place a lien on our home. We engaged Green Attic to insulate the attic of our historic 19th century home. While the crew insulated the attic, some cracks in the plaster ceilings started to worsen and drip so we had the crew halt their work. After discussion, we agreed that Green Attic would remove the plaster ceilings and replace with drywall, which is where the trouble started. When the plaster ceiling was demoed, the crew didn’t seal off rooms with plastic so the entire house was covered in black dust, which we were breathing in. We rushed out to Home Depot to purchase plastic and seal off rooms ourselves to prevent further spreading of dust and risk to our health. You can look at the attached photos to see the level of dust that covered everything in the house - even my work laptop which was on a different floor and completely on the opposite side of the house of the work. The crew threw plaster and drywall debris out of 2nd story windows damaging our lawn and front garden. The crew regularly left large pieces of plaster in our lawn despite our requests that they be cleaned up, and we had to shop vac our lawn multiple times to clean it up (see attached photos). Green Attic did not offer any compensation in recognition of these unacceptable work practices and cleanup, and the owner responded “Green Attic dose it best to respect every client’s house. However during construction things get dirty and things get damaged. Crew could vacuumed the gras upon request.” That unfortunately was only the beginning of the negligent and disrespectful practices (and responses) we endured while Green Attic worked at our home. The crew shockingly dumped and flushed drywall mud down our bathroom toilet into our newly-installed plumbing, which caused our pipes to clog and required an emergency plumber to come fix (see attached photo of hardened drywall we removed from our toilet and our sinks overflowing from the clog). It took weeks to get Green Attic’s subcontractor to reimburse us for the cost of the emergency plumber, and Green Attic offered no consideration on the final bill for the stress and personal time wasted bailing overflowing water out of sinks and our basement. They also used our bathroom as a storage area and splattered paint on the walls, which Green Attic never fixed. Further, the crew only protected our upstairs white carpets with a thin layer of paper, which was punctured during the ceiling demo. Ceiling dust and debris was ground into our carpet over the months long project, permanently staining the carpet. To Green Attic’s credit, they did shampoo the carpets, but after this didn’t remove the stains, Green Attic refused to reimburse us for the $1k+ it cost to replace the carpet. To sum up Green Attic’s approach to customer service, the owner responded “We won’t cover for carpet replacement due to being old and replacement is needed regardless of the stains. Green Attic sent a carpet cleaning company after client decide to keep the old carpet.” The carpet was in good condition before the project and of course we did not accept the stained condition after it was “cleaned.” This was a common theme for Green Attic – whenever there were issues with the work and cleanup, Green Attic’s common excuse was to tell us how our house was just old and that things needed to replaced to begin with or that they were under the impression that we renovating the entire house so that’s why they didn’t take more care – something we absolutely NEVER said. After Green Attic’s carelessness shorted a circuit in the home (and we didn’t have electricity on our second floor for a week!), the owner baselessly blamed us and stated “electric work in the attic is old and not up to code. Green attic is not liable for any electrical issues,” despite the fact he had never once seen our home and our entire electric service was upgraded in June 2021. He even admitted to us that Green Attic doesn't have any in-house electricians and relies on subs so it was further puzzling how he could reliably come to that conclusion without ever having a certified electrician inspect (something we had done the prior month when we upgraded our electrical service). Green Attic also damaged many other parts of our home including the historic woodwork on our staircase (see photo), left a gaping hole in our bedroom floor after losing parts of the floor during the job, left paint stains all over hardwood floors, discarded original historic built-in shelves, broke blinds, and lost original window brass hardware. Oftentimes Green Attic would not approach us about issues encountered such as the lost window hardware. Instead of pointing out this issue and offering a solution, Green Attic simply installed only 1 handle per window (instead of 2) to cover up the issue. We had to purchase new window handles out of pocket (never reimbursed by Green Attic) and have Green Attic uninstall the incorrectly placed single handles and then reinstall two handles on each window. After weeks of requesting the hole in our floor be fixed and paint be removed from other hardwood floors, we were forced to hire a company to refinish the floors and Green Attic did not provide any compensation for this damage. We even had significant issues with Green Attic’s insulation work, which was surprising given that is their specialty. Per the statement of work, Green Attic was supposed to insulate the floor and walls of our master closet, but failed to do so. We had to point this out, and even after Green Attic attempted to insulate the closet, it was only partially insulated and walls in the closet were hot to touch during the day with temperatures exceeding 105 degrees on an infrared gun! As part of their work, Green Attic removed the walls in the closet, which exposed the rafter bays, and replaced with new drywall, which made it even harder to understand how the closet didn't get properly insulated when the rafter bays had been completely opened up. Another incident demonstrating Green Attic’s lack of care when prepping and cleaning after work related to our front deck which we had freshly painted along with the entire exterior of our home in May 2021. During the months long project drywall dust was ground into the deck and stained it (Green Attic did not use a drop cloth on the front porch during the work). Green Attic attempted to clean it at the end of the project by power washing the porch, but stripped paint and wood off the deck in the process. We had to point this out and the crew had to return and use wood filler and repaint the deck. Only problem is that they rushed and got the dark deck paint all over the banister so we had to have Green Attic return once again to repaint. While the deck finally returned to an acceptable condition, we were left stressed and exhausted by having to point out damage and problems day-in and day-out. A supervisor or manager rarely ever came to inspect progress and we were forced to point out many of the issues, oftentimes with no follow-up or corrective action. A cleaning crew sent by Green Attic even showed up with no trash bags and a broken vacuum and then used ours and proceeded to break it! All of this was never rectified or reimbursed by Green Attic. They also took advantage of us by installing baffles in our attic for $1k when we don’t have soffit vents – rendering the baffles useless! We consulted with other insulation companies who explained that baffles are designed to keep a clear flow of air from soffit vents into an attic - without soffit vents there is not air flow that coming from the base of the rafter bays. Another huge problem we dealt with was being caught in the middle of Green Attic and its subcontractor Nixon’s personal disputes (multiple arguments with raised voices occurred in our house between Nixon and Charlie while we were home trying to work ourselves). Nixon was friendly during the beginning of the project, but the relationship deteriorated as we had to point out many obvious touch ups including fixtures not reinstalled and lines not painted straight. Meanwhile, Nixon started to request payment from us multiple times before the work was complete and then harassed my wife by telling her that we were too demanding and he didn’t have time to do all the proper touchups, and that we got him in trouble with Green Attic. He had been cooperative throughout most of the project, but at the end he turned to us to make us feel guilty for expecting a good job and blaming us for the very ugly and public dispute between him and Green Attic. Nixon also did very sloppy work on requested touch ups and actually ended up doing more damage to our house than good. Subsequently, Charlie (a Green Attic supervisor) came to our house, yelled at Nixon, then took my wife outside of our house to tell her to only pay him and not Nixon. At that point we informed Green Attic to not send Nixon back to our home, which Green Attic obliged. Subsequently, Green Attic sent out a new crew to re-do most of Nixon’s work; however, not all the work issues were corrected and Green Attic refused to offer any consideration in the final bill for all unprofessional behavior of its employees and subcontractors which resulted in significant delays and permanent damage. Throughout the work we routinely had to point out poor work that required fixing and we struggled to reach James or Green Attic when issues arose or when there were repeated no-shows. The crews themselves rarely spoke English and could not explain what they planned to do to the house and we could not communicate with them effectively about problems they had caused. We had to go through James and Charlie instead, who were often unreachable or argumentative. We remained patient to a fault in hopes Green Attic would make things right, but we were let down again and again. We communicated with owner via email regarding all of the issues and after his response did not rectify all the issues, we responded, but never heard from him again about a resolution (although he did respond to a yelp review in less than a day and threatened to sue us for "online defamation"). Instead of responding to us to come to a reasonable resolution, 5 months later Green Attic sent an email stating they intend to file a lien on our home with no consideration of all the damage and tremendous inconvenience they caused! We paid $45,164 for subpar work and had to spend thousands fixing damage caused by Green Attic along with the personal time wasted cleaning up after the Green Attic team. If you want you and your home treated with care and respect, Green Attic is not your company.

Green Attic did a fantastic job! They showed up when they said they would and completed the project on time. The crew was professional and friendly. The project manager shared pictures of their work throughout the day and at the end of the project. They cleaned up each day, so the home was left spotless. Big shout out to the crew that included Edison, Keiman and Ronaldo. If you’re looking for a great company to handle big or small insulation job, call Green Attic. They may not be the least expensive, but they will do the best work.

I contacted Green Attic for a quote on re-insulating the second floor of my home, eaves and space under the roof as outlined in an energy audit I had done on my house. Green Attic responded quickly and while their estimator had not read the audit, he responded to every point outlined in the audit independently. I was so impressed by the expertise of the estimator, I quickly cancelled the other people I had arranged to come out and bid the job. My work crew of Gustavo, Keiman and Ronaldo were excellent. They arrived on time, took plenty of photos, outlined any issues they encountered and their solutions. They had to cut an additional hole in the ceiling to better access it, fixed a poorly wired fixture and were extremely tidy, taking pains to protect my house and belongs from the incredible amount of dust created by this process. While I will still need to clean more, I appreciate that they laid down floor coverings, covered things in plastic and thoroughly vacuumed all the areas they worked in - both inside and outside. Initially I had some issues with scheduling the work and communications around when the crew would show up and etc... but the quality of the work done by Green Attic has more than made up for what ultimately were minor inconveniences and the office is very prompt with processing paperwork and sending receipts, confirmations etc... My house is warmer already!

Green Attic Dispute August 30th, Green Attic began insulation on my new house. I had only lived here for a week, the second this company set foot into my household, the worst was yet to come. After Day 1 ceiling began to collapse in Cathedral, crew had to patch and fix the issue with dry wall no problem. As insulation progressed more of the cathedral ceiling began to collapse. Bedroom was ignored as ceiling began to collapse, it was left with cracks in the ceiling in hopes it may not get worse. As the invoice states the crew will take photos and "has to notify customer, provide the pictures before proceeding.' A message was sent that night before the crew proceeded in regards to just leaving the rest of the cathedral alone. Next day crew began drilling holes in cathedral without approval, and neglected to cover walls and openings throughout the entire house as dust and debris scattered not only in the cathedral but into the rest of the house. Day by day things got worse, green attic crew would be asked if they had a window or time frame of days they may show up (notice I don't ask when they will be done). There were no reponses, the crew would just randomly show up in hope I may be home, conflicting my own work schedule. Tim, one of the projector managers, rather then taking the blame on himself, blamed one of their newest staff members Amanda for the lack of scheduling and coordinating, and this wouldn't have happen with the previous person working in their position. When it came to plaster and installing dry wall in the ceiling, the floor was damaged as well as the window screen. The invoice states that for the "Cathedral Ceiling from inside" Owner is responsible for covering or moving furniture, as "insulation" may get into ducts. However, the issue is the crew completely neglected to barely cover anything, so all the plaster and dry wall (which is not insulation) dust was everywhere from the bedrooms, to the family room, to vents not even near or by the cathedral, as they used multiple entry ways to do the job, it had completely covered the entire household like a winter wonderland. September 7, 2021, after living and breathing this great new air quality left behind for over a week now, with a tricolored ceiling, it has literally been a living nightmare. Again this morning his crew randomly showed up to paint with no warning, headsup, and no nothing. I had asked the crew, and pretty much everyone working with Green Attic days in advanced on the daily if they could let me know when they plan to come by, again with no response. This morning, crew shows up again without anyone from Green Attic letting me know ahead of time. I was very patient for a long time, but 10 days is way too long to have the same result over and over. I have had to hire an Hvac Duct cleaning company, purchase air purifiers as myself and anyone else that comes in is constantly sniffling and coughing because that is how great of a job the crew did covering things they were supposed to on their end, even in areas that they were not working. As it States in the contract under the cathedral ceiling the customer is responsible for repainting the aftermath, but you would think after going through this, and not even seeking approval with photos upon preceding this part should be taken care due to their negligence. Now I am left with a damaged floor, damaged window, poor air quality, and a tri-colored ceiling, thanks Green Attic. Reported to the BBB as you can not put this length of a full description so here it is Next step will be submitting this claim to the Illinois Attorney General

They seem to have done a good job, but the communication was not good. The workers, who were really nice guys, came in and asked us what they would be doing. We thought they'd come in knowing what needed to be done. Left the first day without telling us they were going. Also, we understand that people don't want to get vaccinated against COVID-19, but when you send workers into people's homes, and they aren't vaccinated, they should wear a mask. These guys didn't.

If there was an option to give zero stars, that is what they would receive. Green Attic was hired to do some mold remediation and insulation installation inside my condo. Our HOA had some some previous insulation work in the past by Green Attic, so we felt comfortable in their ability to do a good job. This experience was completely different. Not only was their work subpar, but it was downright reckless and dangerous. These people have no business being in the mold remediation business! As with any project, I got 3 bids and they all pretty much said the same thing. They would come in and seal off the area, ventilate and filter the air with HEPA filters while doing demolition in full PPE. They would “follow” the mold to ensure they got it all, kill the mold, have a dehumidifier in the area for 72 hours and seal any impacted areas after treatment. These are general standards for this type of work. Pricing was estimated because until they opened the drywall they wouldn’t know how much work was required. Green Attic did none of this. They sent over a crew that could not communicate. They put up plastic but didn’t secure it to the floor. They didn’t bring in any HEPA filters either. Unfortunately, I didn’t micromanage the crew, so I didn’t realize what had happened until they were half-way through demo. I called the company and they said “that comes later.” To make matters worse, they didn’t even track the mold and actually left drywall with visible surface mold! They didn’t even protect my hardwood floors; just drop cloths! They sprayed a chemical all over which landed on the walls and the floors as well need to be repaired. Dimitri (supposedly the owner) came out and made all kinds of promises to make it right. He sent a crew to deliver a HEPA filter and dehumidifier, put down protective paper, remove the remaining drywall, and secure the plastic. They also fogged the area to kill any spores that may have gotten out. When he left I felt a little better, but that was short lived. From that point on there was zero follow through. One dehumidifier broke within hours, the replacement which was delivered a day later broke after 6 hours. The change filter light that was on for the HEPA filter was never addressed, and the crew never wiped down or sealed anything. Days went by where my house sat until I had enough and hired someone else. I brought in another company to properly do the work. It turned out that Green Attic didn’t even chase the mold because the other company found more. The other company offered a completely different experience. Professional operating equipment was brought in and people in proper protective equipment did the work; properly. If you want to risk your health, throw your money away and get nothing in return, hire Green Attic. If you are like the rest of us, move along and hire a professional company to do this type of work.

I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!

I could not have been more pleased .. from David who came to inspect and set up the project and checked in frequently to check on the progress and Alina who kept us informed about the work scheduling. The 4 man crew who did the insulation were amazing, efficient and did a perfect cleanup. The 2 man crew who came to plaster, sand and paint did an awesome job! I highly Reccommed this company for the great work and people who were so helpful throughout the entire project!

Very professional company. The crews were on time, very courteous, hard working, they sealed off the portion of the house they were working on to keep dust and debris contained and did a very nice job cleaning up when finished. Their quality of work was excellent.

The short version? I spent $4k with this company, got jerked around, and still have mold in my attic. They are the absolute worst contractor, on every level, I have ever dealt with in my adult life. They never took any ownership over their work and actually wanted an additional $4k to try to fix their first attempt. Asking them to honor the warranty stated in the contract was like dealing with a shady used-car salesman -- they never intended to honor their guarantee. It's a tactic to get their foot back in the door and give you another estimate (for work they should have done the 1st time around). To add insult to insult: --Their communication is abysmal (I constantly received conflicting info from the contractors, James, and Tim) --They're impossible to schedule with (1 work day would turn into 3. Often they would show up late, if at all, on scheduled work days. They would also show up unannounced on days they weren't expected. I can't recall them ever showing up at the agreed upon time.) --They can't seem to do a job without denting and scraping up the walls. Arranging for them to come back and repair the damage (after they've been paid) presents an additional challenge. I ended up hiring someone else to solve this issue and will have to take the $4k as a loss.

Having Green Attic out for a quote on attic insulation reminded me once again why it is always important to get 3 quotes. James quote was way overpriced and he wanted to do way more work than was necessary. Not only did he want to insulate the attic but put insulation in our walls because he said they had no insulation-that's not the case at all and is not necessary. We did have some mold in our attic from moisture and he told us it was so bad he had to replace 1200 sq. feet of our roof. He even went as far as saying he smelled mold in our bathroom to make it sound worse than it was. Again that's not the case at all and our mold issue was minimal per several other quotes and there is no need to replace part of the roof as a result. Beware of this company and always get 3 or more bids!

What went well: Green Attic responded to my website inquiry right away and made it easy to schedule an appointment (never heard back from the competition). They provided a detailed and professional quote within minutes of being on site and saved me from spending $20k on an unnecessary new roof. The job could certainly have gone better: --Their lead contractor recommended an additional fan be installed in the attic. He warned the mold would be back. But when I told this to Green Attic's salesperson I got no response. I even sent a reminder several months later -- only to be ignored again. --The major pain point was extensive paint damage done to the hallway leading to the attic. After repeated phone calls, I was able to get someone to come out and repair the damage. --On top of this, their electrician took a shortcut with the bathroom fan and left one of my light switches disconnected (doesn't look good to the home inspector). This required more calls to Green Attic to have them come back out. --Scheduling with Green Attic's contractors was rather difficult and I had to take several unplanned days home from work, as they did not tell me in advance what days they were going to be onsite. UPDATE (January 2021): Above all, it is now 1 year later and the mold has returned (see attached photos). I had Green Attic come back out to take a look since they guarantee their labor and materials. After telling me this additional work should fall under the warranty, they came back with an estimate costing just as much as the original job (which clearly did not solve the problem). Ridiculous and shameful business practices.

The work crew was punctual and hard working. They laid tarps to protect flooring and sealed off areas to reduce the dust and stray insulation. They were conscientious in cleaning up afterwards and in ensuring that we inspected the clean up. With temperatures dropping, we greatly appreciate that James was able to fit us in earlier than the original scheduled start date. We were very happy with the work done and would recommend them.

They did an amazing job. During the initial visit, they addressed all of my concerns and offered options on how to get the job down. On the day of insulation, the team worked very hard. They kept me informed all though it the day. They thoroughly cleaned up and put furniture back. I highly recommend them!

Very professional and responsive service. The results exceeded expectations. Just plan to have a good housecleaning afterwards as the process causes dust, although the team cleaned up as best as can be expected. Absolutely would recommend doing this where needed.

The job went wonderful! It was completed in a little more than a day and my home was left spotless. They even mopped the floor! They went above and behind on each section of the process. We will be using them again for another room in January. We highly recommend them.

They have since contacted me and came out to my house. They were unaware of the service requested and we're unable to perform service due to the outside temperature. They said they would contact me again in 60 days after weather has changed.

I called Green Attic after frantically looking for a company to perform my mitigation after a flood/sewage backup Sunday night. This is my second flood and had horrible experiences with contractors in the past and had never heard of Green Attic, so I was very apprehensive. James arrived to inspect my place, and although he had been up all assisting other flood victims, he was upbeat, super professional, knowledgeable, matter-of-fact, reassuring & kind. He also had a great since of humor, which put me at ease. James' crew arrived shortly after and they got right to work! Charlie & Hugo were amazing. They were fast, efficient and they took soooo much care for my home and belongings. I can't explain to you how big of a deal this is to me! My last contractors were terrible at this. Green Attic did things I didn't even expect because the last mitigation company I used during my last flood did none of these things that Green Attic did. They taped and covered everything that could be touched by dust. They even removed all of my furniture and put it in a safe place in order to clean the rooms properly. They taped the area where my stairs are, so no dust will come upstairs. They taped all windows and covered all clothing & shoes, even covered all my mail polishes. Most importantly they did not cut or remove any walls or anything else that didn't need to be cut, unlike a lot of other contractors that like to fluff the bill or do unnecessary things for more money. Even my insurance company mentioned this about Green Attice after a day received my mitigation claim. James he pulled my iPad out of some sewage water and I asked him if he could disinfect it. I thought he was just going to take it to his truck wipe it down and bring it back. He actually took it to work cleaned it, tried to charge it for several hours, to get it to work again and even called to give me an update. Awwww, this is totally unexpected and sweet! And when Charlie and his team came to pick up the fans, Charlie kindly hosed down and sanitized a sump pump that I had borrowed from my neighbor. Sooo sweet. I wanted to get him a tip for that, I ran in my house to look for cash, but when I looked out the window again he was gone, hopefully I can cash app him for doing that. The bottom line is, they go above and beyond to make their clients happy! I hope and pray to never flood again, but if I do Green Attic will be my first call. Thank you James Charlie and Hugo for everything!!! I would highly recommend Green Attic for flood mitigation.

Highly professional and technical. Big crew, prompt efficient and courteous. Very positive experience. Especially impressed by the instant rebate from Gas company deducted from the bill because they certify the job with the gas company in real time. Not cheap but not more expensive than the other serious bids.

If you are looking for a company that couples outstanding work with outstanding customer service, then Green Attic Insulation is who you should definitely call. I truly wish I would have called them years ago as I have been putting off suspected issues that centered around extreme temperature fluctuations between winter and summer, along with poor ventilation, within my attic. From the time that Tim arrived for assessment after great communication from Alina, to the installation of the insulation and solar fan with Charlie and his team, to a final blower door test, every aspect was performed professionally and as outlined by the quote. The issues identified were explained thoroughly, with the after result reviewed with me to ensure it was completed as expected. The company must take pride in the people they hire because it showed with their skill and personalities. They were great to be around that day. As for pricing, I originally expected the final quote to be much higher, but found the quote to be very fair and reasonable. So again, if you are looking for quality on a job done right, I definitely recommend that you call Green Attic Insulation. Mark S / Grayslake

Using this company was a great decision. They were easy to work with and very knowledgeable. Other companies that came to inspect my attic just told me what needed to be done, this company actually explained what and why. My only gripe would be on the day of the service. They were 15 mins late, but they were so professional and efficient with their work that they finished earlier than expected with no complications. Overall, I wouldn't think twice to use them again if I need more services that they provide.

Highly recommend! Green Attic is thorough, responsive, and professional. Although it has only been a month since we had the work done, the results are clear. Our house is more comfortable, while our gas consumption is down ~30% and electricity is down ~25%. On the top floor, they sealed all the fixtures and blew in cellulose insulation between the ceiling and the roof as well as into the knee walls down to the level of the floor. There is no access to the attic space and there is very little room between the ceiling and roof, which means GA had to cut through the ceiling/ walls and then maneuver in a tight space. They did a great job keeping the number of punctures to a minimum. They also blew insulation into about 2/3 the basement walls, primarily where pipes come in/ out and there was cool air making its way into the house. James conducted the initial inspection and provided the estimate. I gathered quotes from several companies, some of whom recommended different approaches, but I found his suggestions/ explanations the most compelling. Green Attic was slightly more than a couple other companies, but in the same ballpark. I went with GA mainly based on reviews and James' explanations. Alina, in the home office, was very quick to respond to any questions/ concerns I had. The crew worked two full days. They were punctual, courteous, responsive to my many questions, and careful about containing the mess. At the end of each day, they walked me through the construction areas to make sure the cleanup met with my satisfaction. Just as important, they left the impression that they were intent on doing the best possible job (rather than making the most possible money). With an old house, you are always nervous cutting holes and opening things up. Will you discover something that adds new costs? We had one issue with some old cheap drywall that collapsed during the process of blowing in insulation. GA fixed it, no problem. In one of the upstairs bedrooms, more work was required than expected, but they just dealt with it. In the basement, they ended up doing slightly more than I expected. Overall, I got the impression that they take pride in their work and were looking for every possible way to make the house more energy efficient. As noted, I'm very pleased with the results. We've started saving on energy costs and we haven't even gotten to the coldest and hottest months when the real cost savings should kick in. The house was not uncomfortable before the work, but it had cold spots and could take a while to warm up in the morning. Now, the cold spots are gone, the house warms quickly, and the furnace that serves the top floor seems to hardly ever kick on. The basement is actually warmer than the main floor; part of me regrets not having them do work there. Bottom line, you cannot go wrong with Green Attic.
