"These guys did a great job kept everything neat and clean while they where working. I would definitely recommend them to friends and family. I give them 10 stars. Tim Post Castle Mechanical Inc."

"Jesus Duron and Luis Vasquez were fantastic. They completed the work quickly and with care. I’m thrilled that I chose Permaseal for my crawl space and highly recommend this company. If you can ask for anybody at Permaseal, ask for Jesus and Luis. Great guys and very good at what they do!"

"It went really well. Robert Carroll really knows his stuff. Hire this guy. I say that without reservation of any kind. Don't look any further, believe me, I did. This is the smartest guy. He is honest, dependable, offers fair pricing, and his team can do all the work. I got several estimates from A+ rated insulation companies, but Robert was more knowledgeable than the other companies. He was the only one to point out that my soffits were not vented. Apparently, my house was built on the day no one was inspecting. The builder never cut open the soffits. That meant there was zero airflow going through my attic. The attic fan could run all day, but without air to move, it would not do any good. Only Robert noticed this and offered a solution to fix the problem! I asked some of the other A+ companies if they would vent the soffits and they all said they don't do that work, but they would be happy to add more insulation, which would not fix the problem if the attic was not vented."

"We were shocked to learn we had mice and squirrels in our crawl space/attic...and that our insulation was old and useless. We found ARC on Angi's list and were contacted immediately. Within a few days we had a thorough in-home consultation and a proposal. Energy Specialist David Puralewski explained the details patiently and thoroughly, and shortly thereafter the work was performed as promised by Juan, Antonio and Fernando. From start to finish, we knew we were in good hands...an excellent experience!!"

"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 relation"
