Attic Restoration in Two Homes on Property Using Blown In Fiberglass Insulation in Visalia, CA

For this unique project, the homeowner called us because he had two homes on his property, and both were experiencing high heating and cooling bills and uncomfortable temperatures during extreme heat and cold.

Upon inspection of the attics, we found that both attics had about 5-6 inches of old, dirty insulation. Dirty insulation is an indicator that there is air leakage occurring between the attic and the living spaces of the home. 

We began the attic restorations by extracting and disposing of the old insulation in both attics. We then cleaned and sanitized the attics using Nisus DSV sanitizer. This is a concentrated disinfectant, cleaner, mildewstat, fungicide, and sanitizer that kills a broad spectrum of viruses, bacteria, and fungi. Once we had clean areas to work with, we pinpointed all areas where air leakage could occur and sealed those areas with closed-cell foam. This included all top plates, wire and plumbing penetrations, and registers. By sealing the attic, air is prevented from flowing between the attic and the home’s living spaces. Additionally, we installed barriers at any potential rodent entry points to prevent them from accessing the attic. We cleared the soffit vents to ensure improved ventilation of the attic spaces.

We then blew in premium, Johns Manville fiberglass insulation to a height of 14 inches. This provided the Energy Star recommended R38 level of insulation. 

Now, both homes on the property enjoy reduced heating and cooling costs, better temperature comfort, and better indoor air quality for the life of the homes.
