Attic Restoration and Duct Replacement in 1500 Sq. Ft. Home in Fresno, CA

The homeowner contacted us because her home was cold in the winter, hot in the summer, and extremely dusty. The indoor air quality was so bad that her cat was suffering from allergies. When we inspected her attic, we discovered that there was evidence of rodent activity, including an HVAC duct that had been gnawed through and was covered in rodent feces. We determined that the best course of action was an attic restoration and replacement of the broken duct.

We began by sucking out all the old, contaminated insulation and disposing of it. We then replaced the broken duct and cleaned and sanitized the attic using DSV sanitizer, which helps eliminate contaminants and irritants. Next, we meticulously air-sealed leakage points including top plates, registers, recessed lights, and plumbing/wiring penetrations. At this point, we also installed rodent-proof barriers to keep rodents and other pests from re-entering the attic. Lastly, we blew in 14 inches of premium, fiberglass insulation to bring the attic to the Energy Star-recommended R38 level.

As a result of the duct replacement and attic restoration, the homeowner’s heating and cooling costs will be reduced by up to half and the indoor air quality will be greatly improved as the attic air is no longer contaminated with rodent feces and won’t be flowing freely into the living spaces of the home.
