Attic Restoration – Full Extraction of Old Insulation, Air Sealing, Sanitizing, and Blown-In Fiberglass Insulation in Selma, CA

The homeowner reached out to us concerned about the unbearable heat in her house and her high cooling costs during the summer. She also expressed that she and her children had bad allergies, and was hoping that we could help. We took a look in her attic and found that she only had about 5-6 inches of old, dirty, cellulose insulation. There was also evidence of rodent activity. She decided on the spot that she wanted an attic restoration done.

We began the attic restoration by extracting and disposing of the old insulation. We then cleaned and sanitized the attic 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 a clean area 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 space.

We increased the level of insulation in the attic by blowing in premium, Johns Manville fiberglass insulation to a height of 14 inches. This provided the Energy Star recommended R38 level of insulation. 

The homeowner later notified us that she could feel the difference in both the temperature and her allergies in the first few hours after we had done the work. She and her family will now enjoy a more comfortable, healthier home and reduced heating and cooling costs for the life of their house.
