Removal of Old insulation, Air-Sealing, and Installation of Blown In Fiberglass Insulation in Hanford, CA

The homeowner contacted us because his home was uncomfortably warm and his air conditioner was running constantly, causing his cooling bills to be high. He wanted to address the issue with his insulation to help his home retain the conditioned air while also reducing his cooling costs. When we inspected his attic, we found that it only had about 3 inches of old, dirty insulation. This is well below the Energy Star-recommended R38 level, the minimum requirement for our climate. We determined that a comprehensive attic restoration was best to help this homeowner achieve his goals.

We began by vacuuming out all of the old, contaminated insulation. Once the attic was bare, we cleaned and sanitized the entire space using DSV sanitizer, which eliminates contaminants and irritants. We then located all holes, gaps, and cracks and air-sealed them using closed-cell foam. This included all recessed lights, registers, top plates, and plumbing and wiring penetrations. We also installed rodent-proof barriers at any potential entry points in order to prevent rodents and other pests from entering the attic. Once the attic was sealed, we blew in premium, fiberglass insulation to a height of 14 inches, or R38 protection. 

As a result of our comprehensive attic restoration, this homeowner and his family will enjoy reduced heating and cooling costs by up to 50%, a cooler home in summer, a warmer home in winter, and better indoor air quality for as long as they live in their home.
