Best insulation pros near Dunn Loring, VA

"Prodent Homes did an excellent job with our attic remediation. They removed the old insulation, sanitized and re-insulated the entire attic. The owner David was easy to communicate. The crew lead Jose was very experienced and communicated well. The job was done professionally. We are happy with the results and will use them again if we have another insulation job."

"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."

"HIGHLY RECOMMENDED! GREAT WORK AND STELLAR CUSTOMER SERVICE! I had an excellent experience with Founders Insulation and owner Brian Handy. Brian's a great guy—knowledgeable, honest, responsive, and easy to work with. He clearly explained what was needed, what was optional, and why. He showed exactly where the insulation and air-sealing problems were, giving me complete confidence in his recommendations. There was no pressure to add unnecessary work, and everything stayed within budget. Work included removing old attic insulation, extensive air sealing, insulating the attic to R-60, sealing the attic hatch, adding insulation to vaulted ceilings, and spray-foaming problem areas and a cantilever. The team did an incredible job. I was especially impressed with how thoroughly they cleaned up afterward. Most importantly, I've noticed a significant decrease in my heating and A/C costs since the work was completed. Excellent communication, quality work, fair pricing, and no surprises."

"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."

"It was amazing, took all day to get the old insulation out, seal the holes, and refill with new insulation. Would recommend this company to anyone looking for a professional service to improve insulation and save money on heating and cooling costs."

"These guys were the benchmark for contracting work. Quick estimates on pricing that they stuck to. Timely quality work, and a great clean-up effort. 10/10 would recommend for insulation work."

"Window & roof insulation quick, easy, & affordable!"

"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."
