Best insulation pros near Great Falls, 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."

"The company did a good job replacing old insulation in our attic. There was a communication hick-up but the project manager we worked with - Jamie - was able to correct and resolve the issue."

"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."

"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

"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."

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

"I am so impressed with Comfenergy. The sales rep explained why we only needed to improve the insulation at the top of our unfinished basement walls, not the whole thing as another company recommended. So it was considerably less money than we thought we’d need to do the job. Brent and his assistant arrived on time to do the work and were so quiet that we weren’t inconvenienced in any way. I definitely recommend this company."

"The process was explained in great detail which helped me understand what was recommended to have done and why. The Comfenergy contractors that came onsite were super friendly and respectful. They did a great job and showed me the work that they did. The only issue I had was that they didn't know what to charge me after the work was done. I had to look up what I had put down on the deposit, then let them know the balance. The next company to come out was Atlantic Duct Cleaning for the duct cleaning and the Aeroseal duct sealing. Again, the contractors were friendly and thorough. They showed me before and after pictures of the ducts, and I got a report of the Aeroseal results from before to after. I can feel the difference in the warmth of the home. I would recommend both companies."
