The Problem:
The homeowner in Mineola, NY was dealing with high energy bills, uneven indoor temperatures, and concerns about air quality in the home. After inspection, our team at Zavza Seal found several issues inside the attic.
The attic roof rafters had old and damaged batt insulation that was no longer doing its job. There were also air gaps around wires and pipes that allowed outside air, moisture, and pests to enter the home. Poor airflow in the attic increased the risk of mold and mildew, especially during seasonal temperature changes.
Because the attic insulation level was far below current energy standards, the home was losing heat in winter and gaining heat in summer. This made the HVAC system work harder and reduced overall comfort.
Our Solution:
Zavza Seal designed a complete attic insulation and air sealing solution to improve energy efficiency, airflow, and indoor air quality.
Step 1: Removal and Disinfection
We carefully removed and properly disposed of the old damaged batt insulation from the attic roof rafters. Once the area was cleared, we treated the entire attic surface with an all-natural, environmentally friendly disinfectant. This treatment removes mold and mildew, repels rodents, and is safe for people and pets. It has a very low EPA toxicity rating and is odorless.
Step 2: Full Attic Air Sealing
Our team air sealed the entire attic surface. All wire penetrations, pipe openings, gaps, and small holes were fully sealed. This step is critical to stop air leaks, improve comfort, and protect the home long term. This work also supports Zavza Seal’s 10-year warranty on insulated and sealed attics.
Step 3: Foam Baffle Installation
We installed foam baffles where needed to restore proper airflow from the exterior soffits to the roof ridge vent. This airflow helps control moisture, prevents insulation from blocking vents, and reduces the risk of mold growth. The result is a continuous passive airflow system that keeps the attic dry and temperature controlled.
Step 4: High-Performance Insulation
To improve thermal performance, we installed Eco-Batt Kraft-faced fiberglass R-19 insulation in the 2×6 attic roof rafters. This is the maximum R-value possible for that rafter depth.
To meet New York State utility requirements and improve efficiency further, we added Seal Tech R-18 radiant barrier insulation. This brought the total attic rafter insulation value to at least R-38, which is approved by NYS utilities and aligned with current energy efficiency recommendations.
All insulation materials used are environmentally friendly, fire resistant, moisture resistant, and Gold Certified. They also reduce outside noise and improve indoor comfort.
The Results:
After completing the project, the homeowner immediately noticed improved indoor comfort and more stable temperatures throughout the home. The attic now has proper airflow, strong insulation coverage, and a sealed barrier against air leaks, moisture, and pests.
Energy efficiency was significantly improved, helping reduce heating and cooling costs. The attic is now cleaner, healthier, and built to meet modern energy standards in New York.
