Air Sealing

Our air sealing services focus on identifying and sealing air leaks and gaps in a building's structure to prevent the exchange of air between the interior and exterior. These leaks commonly occur around windows, doors, electrical outlets, plumbing penetrations, and other areas where gaps or cracks are present.

  • Foam sealant expands to fill and seal gaps, cracks, and holes, providing an airtight, moisture-resistant barrier that enhances insulation, prevents drafts, and improves energy efficiency.

  • Rafter vents, installed between roof rafters, ensure proper airflow from soffit to ridge vents, preventing insulation blockage, regulating attic temperature, and reducing moisture buildup.

  • Foam gaskets are a compressible polyethylene designed to seal gaps to prevent air, moisture, dust, and noise infiltration, improve energy efficiency, and provide thermal insulation and vibration dampening.

The Big River team employs methods like foam sealant, foam gaskets, and rafter vents (baffles) to effectively seal these leaks. By preventing air infiltration, an insulation air sealing service enhances energy efficiency, indoor comfort, and reduces heating and cooling expenses.

We offer various combinations of air sealing installations to maximize energy efficiency. Our top option includes foam gaskets, foam sealant, and rafter vents (baffles). We also provide combinations of foam sealant with foam gaskets, and foam sealant alone. Prices vary based on the chosen combination. Please contact us for more detailed pricing information.
