Outdated Insulation Removed and Upgraded in Fresno Attic Restoration

David from Fresno gave us a call because his home was struggling to stay comfortable—especially during those scorching Central Valley summers. His HVAC system was working overtime, but the house still felt stuffy and inconsistent in temperature. We headed out to take a look and quickly discovered the issue: his attic had only about 5 inches of old cellulose insulation, which is well below modern standards and nowhere near sufficient for our climate.

Given the condition of the insulation and the presence of debris and dust, we recommended a full attic restoration to ensure long-term comfort and energy savings. We began by vacuuming out all of the existing cellulose insulation and debris. Once the attic was cleared, we sanitized the entire space using Nisus DSV, a professional-grade disinfectant that kills bacteria, viruses, and mold—greatly improving the indoor air quality for the entire home.

We also inspected the attic for signs of rodent entry and sealed off those access points to help keep unwanted pests from returning. Additionally, we cleared the soffit vents to allow for better airflow throughout the attic, which helps maintain a balanced temperature and prevents moisture buildup.

With the attic fully cleaned, sanitized, and vented, we finished by installing a fresh layer of blown-in fiberglass insulation to a depth of 14 inches, reaching the recommended R38 level. This upgrade will make a major difference in David’s home—cutting down on energy bills and keeping the living space far more comfortable all year long.
