"We had Xanvria remove the old insulation in our attic, air seal the attic, and install new R-49 batts. They did a really good job, were professional, and explained what they were doing along the way. Everything came out clean and we?re very happy with the work. I would definitely recommend them."

"Highly recommend for any insulation project. Dan Hope is extremely knowledgeable concerning home insulation and was pleasant to work with. I have cantilevered second story floors and poor insulation was causing a duct vent to develop condensation with this 2024 heat wave which caused moisture to drip down inside of my first floor ceiling. Dan fixed the insulation issue and then some. He inspected the house and advised improving the insulation around a room that sits above our garage that was notoriously difficult to temperature control. I would hire him again for another project in a heartbeat."
