Comprehensive Attic Restoration with Air-Sealing in 2100 Sq. Ft. Two-Story Home in Fresno, CA
The homeowner contacted us because his two-story home was uncomfortably warm as we approached another scorching Central Valley summer. Additionally, his home had two HVAC systems working to keep his house cool, and his cooling bills were already becoming unmanageable with the rising cost of energy. When we inspected his attic, we found that it only had about 6 inches of insulation, and he had several HVAC ducts that were broken and leaking air. In addition to replacing the broken HVAC ducts, we determined that an attic restoration would best help him achieve his goals of attaining a cool, comfortable home and lowering his cooling bills.
We began by sucking out all of the old, contaminated insulation and disposing of it. We then identified all of the HVAC ducts that were broken and leaking air and installed R6 flex ducts in their place. Next we cleaned and sanitized the attic using DSV sanitizer. Once we had an empty and sanitized workspace, we identified air leakage points — including top plates, wire and plumbing penetrations, and recessed lighting — and sealed it using closed-cell foam to prevent air from traveling between the hot attic and the living spaces of the home. We also installed rodent-proof barriers to keep rodents and other pests from entering the space. Lastly, we blew in 14 inches of premium, fiberglass insulation to bring the attic up to the Energy Star-recommended R38 level.
As a result of the duct replacement and attic restoration, the homeowner and his family will enjoy the following benefits:
- better indoor air quality
- reduced heating and cooling bills by up to 30%
- more comfortable temperatures in their home year-round
- higher resell appeal should they ever decide to sell their home
- they will never have to have this work done again — it’s a one-time investment
- reduced wear and tear on their HVAC systems
