"Between Brad K., the company’s support team, and the crews who come out to do the job and execute the work, you cannot select a better company to help you make your home energy efficient and reduce your utility bills by insulating the house and sealing your duct work. As for Brad K., the job begins with Brad coming to your house and conducting an Energy Audit. This gives everyone a far better understanding as to what needs to be done in your home. And, Brad concludes with conducting a “ Test Out,“ to see the improvements. Pepco will offer you a partial rebate for the work completed and they are very satisfied with a 20% reduction. As for us, we hammered Brad with dozens of questions over the course of time before and after we ratified an agreement. In every case, Brad was extraordinarily responsive especially with him being burdened performing audits throughout the day and being offsite. We couldn’t be happier with Brad’s performance. The same goes for the inside team including Jeff, Gordon and Ashley. And, everyone of the guys and their team leads who came to the house not only focused on executing their expertise, but were also very customer focused. In our case, the “test out demonstrated a 36% reduction,“ and Brad believes the partial rebate will be even greater. A Little Constructive Feedback Here: Be sure to ask and fully understand what needs to be done prior to the crews arriving. We had three teams over three days (not in a row) and learned at that moment what more needed to be done to fully finish the job. This will minimize to virtually eliminate any further challenges for the crews and yourselves. However, the job was completed. Over the next 45 days or so, after our utility bill fully cycles, we look forward to seeing the results of Atlas’s work and the reduction in our utility bills. Atlas Home Energy Solutions is Your Best Buy. We are certainly available to provide any further references. RichandJames Peterson Silver Spring, MD (301) 592-1616 Email: [email protected]"

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

These vents help your attic circulate air. With attics reaching over 120 degrees in the summer these are very important. They prevent mold and increase the lifetime of your insulation. Most other contractors miss installing these.
Look at the difference! Our foam is fire-rated which allows us to air seal around penetrations that contractors never could before.
Most homes have penetrations all over there attic. Imagine trying to blow up a balloon with a bunch of holes. It will never fill up. Now imagine trying to blow up your house with air conditioning and heating with a bunch of holes in the attic. It will never fill up.
Recessed can lights are notorious for leaking air. Recessed can light covers help with air-sealing your living space and prevent fires.

"My roof trim is in need of replacement to keep in HOA compliance. Diaz showed up with a free estimate and a more reasonable price than two other contractors who gave me a quote for the job. The work is on a three story townhouse, which is a high risk job and weather is a major matter for safety reason. There was a lot of delay due to weather and scheduling. Diaz was able to handle rescheduling via text and his guys were able to get the job done."

"This was the second time we hired ROI Construction LLC to work on our home and they did an excellent job both times. Originally our roof was replaced and ROI did a fantastic job, going above and beyond in making sure every detail was perfect. Recently we had the roof and skylights of an addition replaced. In both instances ROI charged less than the competitors and the workmanship was high grade. I highly recommend this company."

"Debbie, the AC&R salesperson, was very knowledgeable and confident. They were the 2nd quote I got for work and came in even lower than I expected (which gave me pause as a low bid is a red flag). But true to her word, they did the work professionally (mostly...see below) and promptly. While I had another company do the energy audit for the Pepco rebate, AC&R took over the work, did the blown fiberglass one day and the spray foam the next.



For the blown fiberglass in the attics above our additions, they added spray foam (from a can) around any gaps per the contract and foam board baffles at the soffits. The installer noted that all our soffits were blocked and the batting insulation was too wide for the rafter channels, so he leveled it out as best he could to ensure an even coating of blown insulation. At the end, he sealed up the gaps between the attic and our to-be-finished upstairs (cape cod style, so all one room).



For the spray foam insulation, the team came in the next day, and I had to be out of the house due to fumes. I did come back around noon as they expected to be done well before then. They didn't know I came in and I went to the back of the house to watch TV on my work break. The one annoyance was during their cleanup, one of the installers came down into our kitchen and then saw me. He said he was looking for a vacuum cleaner to clean the stairs. I told him don't worry about the carpet as it was getting pulled up, but this was the one piece of unprofessionalism I noted above. Contractors should NEVER use the homeowner's property; they should bring their own tools, including vacuums!



While the spray foam can get very messy, they kept the splatter mostly contained to inside the crawlspace, not the finished flooring. However, I was surprised that they didn't tape off the outlet covers or light switched. since the particles are so small, we're going to have to replace the switches/receptacles at our cost. Also, there was a storm door screen that wasn't covered and now needs cleaned. Basically, I think they should have taken more care in covering the very few items we left upstairs and the outlets/switches.



They didn't spray around the window frames (large gaps where window weights used to be) because the open cell foam would expand too much. If I wasn't there, I think they would have just left, but it was clear in our contract discussions they needed to insulate those spaces too. They used a few cans of "Good Stuff" equivalent, but didn't fill in the gaps entirely. It did the job well enough, but it's a ding against them as I expected more preparation.



Lastly, I thought that AC&R would walk me through all the scheduling and final "test out" (for the Pepco rebate), but I had to contact them and schedule with someone different each time. They were always prompt, but I expect the experts to know to do this for/with me rather than expect me to know the process. I go through it once in a lifetime while they do it weekly.



While the end of the review sounds more negative than positive, I would definitely recommend AC&R out to others as they're priced right, they have been in business for over a century, and like any contractor, you just need to follow up to be sure everything is done to your satisfaction.

"The work that Metro Insulation, LLC did was well done. The contractor was very kind. I was a new member of Angie's List at that time. I didn't really understand so much what the big deal was. It wasn't a very large break in the price, but it wasn't a tremendous amount of money so I was glad we did this. I would recommend the company. The insulation they installed did end up making our house warmer. The price was considerably more than what I expected it to be, but I really wanted to get this done so I didn't comparison shop. I would shop around more before making a decision whether I would use them again."

"AHC, Inc did a very thorough job walking our roof and finding areas that required caulking; replacing loose nails and shingles. The technician Austin Bunnell, as a total courtesy, removed the base to an old satellite dish that was never taken down.. He then caulked that area for us. Great customer service was provided and care taken to respect the household (protective face mask and shoe covers were worn). A very good value at $149.00"

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"Working with Sino-America General Contracting was excellent from start to finish. Our project was a complete redo of the basement - we had demo'd floors, walls, and ceiling ourselves, and hired Mason and his team to help install a custom bathroom under the stairs complete with custom shower pan, under floor heating, and tiled walls. We also had them build a small mechanical room, install insulation, redo flooring, redo drywalls, build a drywall frame around the HVAC, install new vents and ducts, and install recessed lighting. They also built a bannister for the stairs leading to the basement and installed a matching railing and bannister for the upstairs. Finally the installed new doors for the upstairs and downstairs, and moved the downstairs door to the right a few inches in order to accommodate our design. This necessitated external brickwork and they were able to match the 70 year old brick extremely well. From the initial meeting Mason was responsive and professional as we went back and forth on the design of the bathroom. The designer (whose name I sadly can't remember) did a fantastic job with clever use of space and a keen understanding of how the design will translate into real life. Experienced in AutoCAD - they provided clear and very accurate 2D renderings and beautiful 3D renderings of the finished design, including 3D renderings of the style of sinks, toilet, lights, and mirrors we wanted. The contract was well presented and explained with the scope of the project clearly identified. At no point was anything unclear. He worked with a punch list with holdback until the punch list completed. Communication of contractor's needs and schedules were well coordinated with mine so there were no surprise missed days. Worked weekends to help expedite project completion. Any issues or concerns that we had during construction were explained or addressed right away. There was an accidental error during installation of the under floor heating and Mason and his team addressed it which required removing tile, reinstalling the heating system, testing, and replacing tile. They built a good relationship of trust with excellent communication throughout The quality of the work is excellent and stands up to close scrutiny. Smooth, crisp, and even drywall and corners, including on strange angles and niches. Beautiful, uniform color application Beautiful tiling and corners. The attention to detail was also very good. As an example we turned the remaining space under the stairs into a kitty-litter area including custom trapezoidal door and externally vented bathroom fan. Despite it being in a low-traffic area, all the work in that miniature room was of the same quality - crisp corners, well-joined shoe-moulding, and nicely painted edges. I recommend Sino-American Construction without hesitation."

"Overall it went well except I didn't get the other estimates I requested for insulation and gutters. This was not the low bid but they have done several cedar roofs in the area and have a good reputation. The end result looks really good.

Insulation questions, answered by experts

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

There are two reasons why cellulose insulation repels rodents (and insects). First, the insulation has been treated with boric acid, which is a natural pest-repellent. In addition, the loose-fill style of cellulose creates less-than-ideal conditions for mice and other rodents to nest and burrow, helping to keep them at bay.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

Yes, many professionals offer insulation options, such as insulated siding (including insulated metal siding), to improve your home's energy efficiency.
