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

"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!"

"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."

"The experience with USA Insulation was very positive from start to finish. From the first call, the owner, Brian, spent time discussing my questions about the company’s services and insulation products. Mike came on time for an estimate and also helpfully discussed our questions about cutting into a plaster ceiling, what would happen if asbestos or animal intrusion were discovered, covering light fixtures and other initial install work, R-levels, insulation types, etc. After getting quotes from two other well-reviewed and professional companies, we had follow-up questions for Mike about foam insulation and caulk to seal potential cracks and openings, which he helpfully answered by email. Mike was always quick to say what extra services that we would not benefit from. USA Insulation does not install access hatches after cutting a ceiling access point, unlike the other two companies. However, USA Insulation gave the most competitive bid at the outset, and gave us confidence about how they would handle anything unexpected and stay close to their estimate. Because they are popular, they could not come to Northwest DC for a couple of weeks after we decided to move forward. They were worth the wait. The two-person crew that came arrived on time, were very professional tidy, and patiently walked through my questions confirming the products being used, R-levels, light covers, and letting me take a look and take photos at each work stage. They covered floors and furniture before starting, and took out debris and vacuumed once they finished. They also installed some insulation in our basement where we had done some plumbing work behind the walls. When I asked them to add as much R-19 insulation that could fit between the pipes and wall, they obliged and carefully tucked as much as they could – a process that included contorting into awkward spaces to insert the insulation. Because our attic’s roofline and beams prevented the team from installing 4 out of the 6 light covers, Brian reduced the final cost. It has been a week since the insulation was installed, and we are pleased with the comfort of our room temperature now. We are very pleased with USA Insulation’s services."

"These guys are as good as it gets. First class. Carrier Presidential Award. Workmanship, equipment quality, are absolutely flawless. Owner typically does the estimates and he is no pressure. Company installs water heaters, HVAC. Pricing--very fair. You generally cannot hear the equipment running except the outside unit which is also very quiet (about the same loudness as a conversation). Our house is quiet, comfortable with even temperature on all three floors (within one degree) even though we only have one large unit. Owner came out and personally inspected every inch of the jobs. Another owner came to measure sheet metal. Installed extra return air ducts, reason given "it should have been there to begin with and will help the system work better". Water heater had expansion tank installed, reason given: "we do it on all of our water heater jobs, it is better for the tank and helps the water heater last longer". Company used tin plated evaporator coils rather than standard evaporator coils, reason given "more durable, higher quality, less chance of leaks". With the fresh air intake, drywall had to be cut in the ceiling--there was not one speck of drywall dust, dirt or any debris anywhere throughout the house. Cleanup work--looked better than when they started. Used drop cloths everywhere--even in the driveway. Personnel are extremely polite, hard working, well trained and wear shoe covers. Permits were pulled from Fairfax county. County came out and inspected the work and said--I am going to look at everything sir, but, Mann-in did the job, I have never had to call them to re-do something not in the 20 years I have worked for the county."

"The work was satisfactorily performed. Alex worked steadily for 1 1/2 days to repair damaged areas caused by water. He was very professional and methodical. He ensured that the non-work areas wete kept clean and not damaged. He reinstalled insulation that had been removed from the attic; replaced, primed and painted drywall in the ceiling and walls; replaced a part of a door casing; and installed a flush mounted light fixture. Overall, he did a very good job."

"Excellent quality at 1/3 cost of a big area insulation company."
