"Our first interaction with Atlas was with Shannon. As knowledgeable and personable as one could hope for. She clearly explained cost effective measures to better insulate our house. We opted for sealing and insulating our attic and weather stripping a number of doors. We were very pleased with the workmanship and the energy savings they produced. They also helped us get a PEPCO credit which reduced the overall cost of the job. A winner!"

"Stephen and his team did a fabulous job of insulating a space behind a bedroom wall and adjacent bathroom wall that was completely uninsulated. We suffered through two cold winters that heaters couldn't solve in these rooms. Stephen evaluated the project efficiently and then oversaw the work. It was performed beautifully by the team and they cleaned up before leaving. Everything was immaculate. Most impressed with this company and this project manager."

"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."

"Highly recommend. Exceptional and professional service from their contractors and most especially by Nolan Walker (Performance Consultant). Nolan showed photos taken of my home's ductwork and insulation and provided a list of options and the cost of each project so that I could make a well informed choice of which projects to pursue. He took his time and was honest and understanding - not aggressive like other companies I have dealt with. His test-out and follow-up appointment was just as thorough. It was a pleasure working with him."

"We needed insulation applied only to the underside of the house at this time. The guy who came out to give an estimate was great. The guy that came out to do the spray job (I expected a team and got just one guy) was super nice. The spray foam would appear to be difficult to manage during application as some spots only have a skim of insulation while others seem to have 7 inches of it. The office..... trying to get any information from that office.... was a hassle way beyond my wildest nightmares. Getting the estimate took days, getting scheduled took days. They have only one person working to do all of the scheduling and she "is out of the office" during a whole heck of a lot of "our office hours are from...". Figuring out what I needed to know to pay online took pulling teeth. It was the best price I got and it will make a world of difference to that house structure and its moisture issues.... but good grief!"

"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 team arrived slightly early to be well prepared to start the job on time. As they began they laid down protective barriers to keep the home clean. While in the attic they blew in the insulation with an even consistent barrier, ensuring that all locations with infrastructure were well covered. As they wrapped up the job, they cleaned behind them as they closed up the attic, removed the floor coverings and were on their way. The only way I can tell they were here is that the heat runs less in the winter and the air conditioning runs less in the summer. I would recommend this process and this team to anyone who owns a home and has not insulated their attic."
