Insulation Contractor in Herndon, VA

The crew did a wonderful job, very professional. Covered all access areas and cleaned up fine to the last drop. I highly recommend them. They are coming back to install the attic tent over pull down steps. It was but the standard size. They promised to order it and come back to install. I highly recommend Kevin crew to anyone. Price was 50% less than the other estimates I got.

I would give Kevin and his team 10 stars if I could! They were professional, completed the work on time, and made sure everything was done properly. His pricing was very reasonable—in fact, it was the best out of the six quotes I received. Don’t waste your time getting multiple estimates. Go with Kevin—you won’t be disappointed!

Kelvin Insulation did an outstanding job bringing my attic up to code with blown-in insulation. From the start, the owner guided me, which I really appreciated as someone unfamiliar with insulation options. The crew was professional, sealed every nook and cranny, and replaced the baffles that had been installed incorrectly by the original builder, he even showed me before-and-after photos so I could see exactly what was wrong and how they fixed it. They finished on schedule as promised and cleaned up thoroughly after themselves; you'd never know they had been there. On top of all that, his price was the best I found anywhere in the area. I highly recommend Kelvin Insulation to anyone needing attic or insulation work!

Kelvin's insulation company expertly insulated our attic and crawl space with closed cell foam. After receiving 3 estimates, Kelvin offered the best price. I highly recommend Kelvin and his crew for their excellent work and thorough clean-up.
