"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."

"DMV Insulations is a great company to work with. The company focuses on your personal needs, always on time, and great customer service! Mark was able to answer any questions I had, and provided me with useful information. I would recommend this company to anyone with attic insulation needs."

"From initial contact with their sales department we've had a great experience, Corey did an excellent job of taking pictures and showing the problems in our attic. Their level of communication from emails to phone calls was precisely correct by contacting me when needed and not too much with pictures detailing each solution and its associated cost. On the first work day their crew called ahead of time, arrived promptly and came prepared with masks, plastic sheeting, full body outfits and cloth covering for the stairs. In just over 6 hours they had cleaned up the entire attic removing bad sub-floor and other insulation, laid out the foundation for building a large deck space and placed part of the first layer of materials down. They also sealed the attic door along with some of the air vents and ceiling fans. They completed insulating my front porch overhang and cleaned up all of their mess very well. Painters tape was used on corners where they we’re most likely to bump into it for protection and plastic sheeting was setup precisely where needed to keep dust off of our hallway things next to the attic entrance. Overall it was a great first day and they even spotted an issue from a previous vendor who failed to properly connect some of their duct work together (which was the original cause of my daughter’s room temperature being so hard to control the temperature and not easy to spot). The only complaint I have is that while I fully expected the need to finish our attic sub-floor, remaining layers of TruSoftTM Cellulose on the main floor and encapsulate the duct lines with Polyurethane Spray Foam all before finishing with blown-in insulation, they left a key piece incomplete. When leaving they left the duct work leading from our main trunk line to my daughter’s room off. This left a hole in the main trunk line reducing heat in all upstairs rooms but most important is that nothing was connected to my daughter’s room. So around 6:00am she woke up coughing as we noticed the upstairs was around 56 degrees. Overall a simple heads up would have solved everything as we have space heaters, however I did not look into the attic when they left so that’s my fault for not knowing a key piece of the duct line was missing. Based on the overall work complete I would still very much recommend them as Robert (onsite team lead) was very good at communicating and the crew we’re all quite friendly. Their work will last for the lifetime of my house and has already added value to the sale price. In the end they made a really nice attic deck leaving me with plenty of useable storage space. While this is not the cheapest company, the quality and knowledge that I never need to worry about my attic again is certainly worth it."

"The work here in 2023 was a re-do of work done in 2016, of the top floor of this house, with a Mansard roof. It was basically uninsulated in 2016, and the work then had a big impact because at least some insulation was blown in. But large regions which I was told had been filled were not. I borrowed an IR camera, which showed that one wall that had been filled in was losing its fluff. The work this time here in 2023 was to fill in the parts of the wall not filled in last time, and restore any insulation lost during the pandemic years. They also added additional insulation to parts of a wall not covered the first time. It's had a very noticeable effect. The temperature before the re-do was sometimes sweltering—I couldn't keep chocolate up here, lest it melt—but after filling in the walls fully, even on those days that tell us climate change is looming, the upstairs is comfortably habitable. The total I gave of $3,800 includes the full project, including $1,500 for this round."

"After researching and obtaining quotes from a number of companies, I selected The Fifth Fuel to air seal and insulate my attic (blown-in cellulose), cantilevers, and rim-joist. From the initial consultation with Adam to email follow-up, the project and my options were clearly explained. When I asked about putting a higher R-value in my attic, Adam provided the price but explained why it didn't make sense for me. I appreciated that he didn't try to oversell me. The proposal laid out everything they would be doing. The cost was reasonable. It wasn't the lowest bid, but was less than 50% of some other bids. The day of installation, the crew arrived a bit early. Throughout the install they were professional, kind, and clean. They protected the inside and outside of our house and vacuumed afterward. They conducted a blower door test at the end to quantify the difference made by air sealing. Within two hours of them leaving, we've already noticed a difference in our comfort and our A/C is not even running half the time it was before."

"I have to restrain myself from going overboard recommending Northern Virginia Insulation. Of the responses supplied by Angie's List, NoVa Insulation was able to schedule the first in-home appointment. They asked for a half hour to assess the opportunity. (Another company wanted to set up a 2-hour appointment with both owners present, which looked too much like an invitation to a sales pitch, so we passed on them.) Jeff, the owner, arrived when expected, took only as much time as he needed to gauge the materials and effort involved and work up a quote. He was pleasant, focused and professional, providing a price without pressure or drama. His crew was able to perform the work within a week, arriving on time and taking extraordinary care to avoid damage or leaving debris. All-in-all the experience was first-rate, from responsiveness, to price (best of all the quotes), to quality of work. If you can get them, do so. Highly recommended!"
