Get matched with top insulation install or upgrade pros in Potomac, MD

"I recently purchased a house built in 1930 that had it's original insulation (and plenty of areas with no insulation at all). I requested multiple quotes, David was not the cheapest or most expensive, but he was by far the most thorough in his review of what I needed. We are feeling an immediate improvement in the house now that the work is done. He cleaned up well after himself. He was easy to work with and did stellar work. I highly and enthusiastically recommend him and his team."

"Very well. Originally contacted them to do home energy audit as part of PEPCO program. Very thorough and informative. We knew we needed insulation in the attic, and some other issues. There was no "hard sell," just clear information. The insulation work itself exceeded my expectations. The crew was very professional and informative."

"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."

"Diaz and his crew were fantastic - we've hired them several times over the years because they are reliable and do a great job with an eye for details. We had new hardwood flooring and carpet installed in our home in addition to having the entire interior and exterior of the house repainted. They always leave the repair/renovation site very tidy. Would hire them again!"

"We hired ROI Construction for replacement windows and were satisfied overall. They were open to price negotiation (we had competing bids) and flexible on scope, we added shutters at a reasonable cost. One install issue came up, but they resolved it within a couple weeks. Communication was steady throughout. Would definitely consider working with them again."

"In January of this year, I had another company come and take out the old insulation and install the blown-in insulation. However, they botched up the job and we found ourselves constantly vacuuming the insulation that was coming down through all the recess lights. They hadn’t bothered to seal them correctly. They also created so much mess removing the old insulation; so we had to move to the basement while cleaning up the main floor from the messy job they did. That’s when Dan was called in to remove the blown in kind and install the blue jeans insulation. Dan suggested the blue jeans batts, knowing my chemical sensitivity. I hadn’t known such insulation existed and am grateful he did to minimize exposure to chemical. I was very impressed from the moment I saw the crew wearing a suit that was clearly designed to protect them. Dan’s crew discovered that the other insulation company had not properly removed all the old insulation company, and Dan could have charged me more for the extra removal work, but he stuck with the quoted price and did an amazing job. He made sure I would not be affected by the removal of the old blown-in insulation(have asthma). This time no dust was created while removing the blown-in insulation. I can’t say enough about Dan and his crew. I am so grateful to him and his crew. Dan is honest, professional, empathetic, and is meticulous about getting job done right. I would most highly recommend him to anyone for any type of insulation work."

"USA insulation was responsive and was able to get my the job done earlier than expected. Workers were friendly, knowledgeable and efficient. This was my second time using USA insulation and would use them again."

"Our 18 year old builders grade HVAC system was approaching end of life. The unit was a Rheem that ran off propane gas. One of two original HVAC systems in our home. So, we proactively decided to retire the original system this spring. I have been a Mann-In customer now for around 10 years now. They already replaced one of my two HVAC system 7 years ago. Also hot water tank about 5 years ago. All in all very happy and familiar with them. Very professional proposal with half a dozen options both in terms of level of efficiency, upgrades such as humidifier and better air filtration, and warranty upgrade. Competitive pricing. Mann-In scheduled my install within a week. I made sure I got on their schedule before the spring. As always, Mark and the installation crew show up on time and hardly take a brake till job is done. Meticulous work. They put drop clothes everywhere. I've tried the other giant heating and cooling companies in past. But, I prefer the more personal, responsive, and nimble Mann-In. Still run like a family business. Although, I am seeing more of the owner's son ( Trevor), Chuck Brown still comes out to pre plan the major projects and make sure everything is engineered properly for install date. He often points out or fixes things from previous builder. Thanks guys. Keep up good work."

"It only took an hour and a half to blow in the fiberglass insulation. <br /> The only downside was the cleanup wash't very good, as we had to vacuum the hall and the stairs after they left. <br />"

"After checking Angie's List and with the Better Business Bureau, I called DeVere. Within just a few days Joel arrived at our door to look at what was needed and to give us an estimate. At no time did we feel pressure to sign on the dotted line. Joel was professional and obviously knows the business. Once we received Devere's insurance certificate we scheduled the work. Armando and a helper arrived in their work truck and proceeded to rip out all the old insulation and replace it with the new materials they had brought. It was a horribly messy job getting rid of the old insulation but the crew did it without complaint. Once they were done not a trace of material was left behind. The new insulation not only looks great but it does a good job of keepint the bathroom much warmer than it has in the past. Armando and his helper also did a terrific job wrapping the pipes. Neighbors have experienced burst water pipes this winter due to the bitter temperatures and I have DeVere's crew to thank for not having to worry about ours. We could not be happier and just wanted to say thank you."
