"Our install was 23 May and I regret it. First: When they said they were complete and asked if I wanted to take a look. I did and a large area over our master bath was not covered. When I asked why they said there was plenty insulation already and it didn't need covered. ? Remembering the demonstration at the home show illustration, I asked it to be covered and they did. Second: They started work outside. I went to check and found they were installing 8"x16" white vents on our brown vinyl siding eves. The siding was already vented for the air flow where needed. I asked why. They said it was standard and that people would just paint them. I stopped them there. After they left, I discovered they just screwed two panels over they vented siding and two where it wasn't vented. They cut 4"x4" holes in the siding to expose solid wood panel. One of the two they drilled several holes before covering it. That is why I have no confidence that any of it was done correctly. Only time will tell if "

We are extremely passionate about the work that we do. You can depend on us to provide a high quality service at a fair and honest price. Customer Service is our highest priorit and we provide a Free estimate! High Energy bills and Comfort issues can be directly attributed to a lack of Insulation and a leaky uncomfortable home. Since we are Building Science Gurus, we can directly fix Air leakage Issues using Blower Door directed Air sealing (Weatherization) with non-toxic low VOC caulking, sealing light cans, outlets etc....contributing to overall leaky home. In addition, most homes built 15-50 years ago are all lacking the proper insulation needed to have low utility bills and comfort issues Cellulose insulation is the most energy efficient attic insulation on the market! Giving a higher R-value per inch than fiberglass and air tight. We test homes before and after will provide 30-40% more air tightness than fiberglass.
