Attic Insulation & Air Sealing in Whitesboro, NY

This attic was experiencing energy loss due to outdated fiberglass insulation, air leaks around fixtures and penetrations, and improper ventilation. These conditions often lead to drafts, inconsistent indoor temperatures, and increased heating and cooling costs, especially during extreme seasonal changes in Whitesboro, NY.

To resolve this, we removed all existing fiberglass insulation and used a professional process to fully air seal critical areas, including light fixtures, plumbing penetrations, and around the chimney. We improved airflow by installing proper ventilation and soffit air intake, then added insulation dams along the catwalk for protection and structure. The catwalk itself was upgraded with 4" rigid foam board and topped with OSB for durable, accessible storage, while the area beneath was dense-packed with cellulose for complete coverage. We also removed the whole home vent fan and attic hatch, along with the attic vent fan, and restored the space by patching, sanding, texturing, and painting the affected drywall areas.

The attic was finished with 14" of blown-in cellulose insulation to achieve an R49 rating, ensuring consistent thermal performance. Materials used included cellulose insulation, rigid foam board, OSB, air sealing foam and caulk, ventilation components, and insulation dams—resulting in a properly sealed, well-ventilated attic designed for improved comfort, efficiency, and long-term performance, with adjustments made to exclude insulation in the garage area.
