"I've been trying to find an expert in insulation for months to come out and tell me out to properly insulate around a removed chimney and Comfenergy was the expert I needed. Even though the insulation part of the job was too small for Comfenergy (wasn't above their minimum quote value) they were happy to give me their expert advice and I appreciate the time spent as I now know what to ask the roofing contractor to do in order to insulate this correctly. Thanks!"

"I am very pleased with how my attic insulation project turned out. when the company came to my house to give an estimate they evaluated my current insulation, told me what I needed to bring my home up to the current standards for attic insulation. (r49) more importantley they told me what I didn't need. I highly recommend this company for your insulation project."

"The project was to insulate a cantilever kitchen bump out that had sink pipes running under it. Both the sales adviser and the project manager were outstanding. Mike Wilson did a great job explaining everything he was doing as he was doing it, capturing with photos and doing everything the right way! Definitely recommend them and use them again."
