The Problem: Poor Insulation and Mold Risks in Attic
A homeowner in Brooklyn, NY contacted Zavza Seal after noticing high energy bills, uncomfortable indoor temperatures, and signs of mold and mildew in their attic. The attic space was poorly insulated, which allowed heat to escape during the winter and enter during the summer. Additionally, moisture accumulation in the attic created the perfect environment for mold growth and potential rodent intrusion.
The homeowner wanted a solution that would improve energy efficiency, prevent mold and mildew, and make the home healthier and more comfortable year-round.
The Solution: Attic Insulation and Disinfection by Zavza Seal
After a detailed inspection of the attic, our team at Zavza Seal developed a comprehensive plan to address the homeowner’s concerns. We focused on disinfection, mold prevention, and installing high-quality insulation with moisture protection.
Step 1: Disinfection and Mold Prevention
We began by spraying all exposed surfaces of the attic with an all-natural disinfectant. This treatment effectively removed existing mold and mildew and also helped repel rodents. The disinfectant we use is highly effective against viruses and bacteria, has the lowest EPA toxicity rating, is non-flammable, non-irritating, and odorless — making it safe for homes and families.
Step 2: Attic Insulation
We installed loose-fill cellulose insulation in both the front and rear sections of the attic. This insulation type was chosen for its excellent thermal performance and environmentally friendly properties.
- For the front of the attic, approximately 706 square feet, we installed R-49 loose-fill cellulose insulation to provide maximum heat resistance and energy savings.
- For the rear of the attic, approximately 353 square feet, we installed R-22 loose-fill cellulose insulation, ideal for the smaller space while still delivering improved comfort.
The cellulose insulation also included a built-in vapor barrier that helps block moisture and prevent future mold or mildew growth.
The Result: Energy Efficiency and a Healthier Home
The attic in this Brooklyn, NY home is now properly insulated, more energy-efficient, and protected against mold and mildew. The homeowner noticed an immediate improvement in indoor comfort and expects to see lower energy costs in the coming months. The added mold protection and rodent repellence give the homeowner peace of mind knowing their home is healthier and safer.
