Spray Foam Insulation in Ashburn, VA

Extremely detail oriented and all around great people!

Great customer service from the staff.

Timely response and professional work

The whole insulation experience with Comfenergy was well organized and professionally completed on schedule. We immediately felt the difference and the room temperature held to the thermostat settings. Our electric bill is lower. It was worth the investment.

We contracted with Comfenergy for insulation removal, air-sealing, and new insulation at a historic hotel renovation we are managing while the building remains occupied. Access was difficult and we had to protect finished areas and Guests below. Their crews showed up consistently, worked clean, coordinated with other trades, and stayed on schedule. They installed an attic catwalk system, sealed penetrations properly, and completed the work without disrupting the hotel's operations. We had zero issues during the project and the Owners are extremely satisfied with the results. I would absolutely hire them again for future projects.

We chose this company based on some coworkers recommendations (I am a licensed realtor of 20 years in this area) and the crew went above and beyond expectations. Final product (new attic insulation) replaced what was most likely original insulation, is now to code for our county and will pass any home inspection. I had quite a lesson on attics from this company and learned a lot during the process. We also want to give a special shout out and thank you to Carlos on the install team. He noticed some electrical items that needed to be addressed in the attic before new insulation went in, otherwise we would not have known. I was able to bring in a licensed electrician to get the work done. Thank you Carlos!!

We used NOVA Spray Foam Insulation for our new out building that houses our company office. The guys did a great job, were punctual and left the building neat and clean. In addition, our building is staying nice and warm. We would recommend them as well as use them again in the future.

I called up Nova Spray Foam to repair a significant void underneath my front step. They provided a timely quote (extremely competitive), and completed the work within a week. Nova Spray Foam went above and beyond to ensure that I was a happy customer. I highly recommend their services and would use them again in a heartbeat.

I own a remodeling company called Evergreen Contracting Services LLC and we our top rated on many peer to peer sites, and only work with the best craftsman; I hired this company to insulate; to help us with a late 1800's garage/gym conversion, and it had rough cut timbers everywhere, and Ken and Bonnie were great, they helped us exceed county code by using there closed cell spray foam walls, ceiling and floor, it was as warm as toast after they got done. I highly recommend them to anyone!
