Blocked Vents, Rodents & Air Leaks Resolved with Attic Restoration in Fresno, CA

Jenny reached out to us from Fresno because her home was always uncomfortable—too warm in the summer and chilly in the winter. Her HVAC system was running constantly, but it just couldn’t keep up. Once we got into her attic, it became clear why: the space was in rough shape. There were extensive air leakage points throughout, evidence of rodent activity, and her soffit vents were completely blocked, choking off ventilation.

We recommended a full attic restoration to solve the problem from the ground up. Our first step was removing all of the old, contaminated insulation and thoroughly cleaning out the attic. Because of the rodent activity, we sanitized the entire attic with Nisus DSV, a hospital-grade disinfectant designed to kill bacteria, viruses, and fungi—crucial for improving the home’s indoor air quality.

After sanitizing, we moved on to air sealing. We carefully sealed all penetrations—top plates, plumbing and wiring cutouts, and any gaps around registers—using high-performance closed-cell foam. This drastically reduces the amount of air that escapes from the living space into the attic.

We also addressed the ventilation issue. Blocked soffit vents were preventing proper airflow through the attic, contributing to excess heat and moisture buildup. We cleared the vents to ensure the attic could breathe properly, which helps extend the life of the insulation and the roof itself.

Finally, we installed premium blown-in fiberglass insulation, bringing the attic up to an R38 level—which is the Energy Star recommended standard. This ensures optimal thermal performance, even in the peak of summer or coldest days of winter.

Now, Jenny’s home will stay more temperate year-round, her HVAC system will work less, and the indoor air quality is significantly healthier. This attic restoration is a long-term investment that will pay off in comfort, savings, and peace of mind.
