"David Sampson of Prudent Homes did an amazing job, I could immediately tell the difference in temperature in the garage and our two pantries where Dave applied blown-in insulation directly above. He made sure to protect all soffits and recessed light fixtures. He also applied insulation around the attic opening and cover. The price Dave charged was well less than a competitor, and Dave was much more thorough in his initial assessment. Dave and his worker made sure to clean up where needed. I highly recommend Dave and Prudent Homes, and will definitely use them again for future insulation needs."

"Lets just say our problem is gone. We had our attic floor air sealed and added cellulose insulation to get it to a R49. We also decided to add a radiant barrier to deflect as much heat as possible. The results exceeded our expectations. The installation crew was great! They showed up on time and knew what they were doing. We would definitely recommend Comfenergy to anyone who needs help."

"pleased with the new insulation in my crawl space, any place where a rodent could possibly be entering my crawl space was fixed with foam seal. The crew was efficient and were care of not making a mess when removing the old insulation. I am very happy with this contractor. fully recommend as another contractor came in seemed to make up problems that were not there. For instance a leak that was not there. trust Mark at DMV as he is honest and knowledgeable of the products he sells and I having him back for a estimate to do my attic."

"I had a leak in the roof that damaged my ceiling. Oscar and his team came out quickly and found the source of the problem. They fixed the roof and repaired the ceiling damage. Great job at a very reasonable cost. I will definitely recommend him and hire again for future work around the house."

"They wanted to inject very expensive sealant into the ducts to seal the seams. The company I hired used insulating tape over the seams instead, for a greatly reduced price. The total price difference in their proposal and the company that I hired was about $4500."

"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.
