Best Insulation Contractors in Concord, CA

Yes. We insulate existing walls by drilling a small hole (1.5-inch diameter) through the exterior or interior wall covering, whichever is least invasive, we then check for structural blocking or laterals. We pump in under a small amount of pressure dry borate cellulose to dense pack the cavities. We plug and patch the holes with the appropriate material and make ready for final covering. Fiber glass can also be used instead of cellulose as a blown-in blanket.

Insulation works by providing a resistance to the flow of heat. Just like when you put on a jacket to help keep you warm in the winter, you want a blanket around your living space to help keep the cold out and heat in. In the summer months, you want your house to stay cool and comfortable. Simply stated, R-value is the thermal resistance to heat. The higher the R-Value per inch, the better protection from heat and cold. Insulation standards in the Bay area counties is dictated by the climate code of your area and local building authority.

Blown-in fiberglass is slightly more expensive than cellulose. It depends on the application, brand used, R-Value desired and location of installation.
