Air Sealing Installation
Contractors in New York

Air sealing is the process of closing gaps, cracks, and openings in a building’s envelope to prevent uncontrolled airflow between the interior and exterior. It works by targeting areas where air leaks commonly occur, such as around windows, doors, plumbing penetrations, electrical outlets, and the attic or basement. By using specialized materials like caulks, foams, weatherstripping, and gaskets, air sealing creates a more airtight environment.

This process not only enhances energy efficiency but also improves indoor comfort by eliminating drafts and maintaining consistent temperatures throughout the property. Air sealing further reduces the strain on heating and cooling systems, resulting in lower energy bills and a reduced carbon footprint. Additionally, it helps prevent moisture infiltration, which can lead to mold growth and structural damage, making it an essential component of a well-maintained building.

Air sealing is crucial for maintaining energy efficiency, comfort, and structural integrity. Here are the best areas to focus on when air-sealing your house:

Best Areas to Air Seal in a House

1. Attic:
   • Seal around recessed lighting, attic access hatches, and gaps created by plumbing, wiring, or ductwork to prevent warm air from escaping upwards.
2. Basement and Crawl Space:
   • Address gaps along the foundation, sill plates, rim joists, and utility penetrations to reduce drafts and moisture infiltration.
3. Windows and Doors:
   • Use caulk and weatherstripping to seal leaks around frames, thresholds, and moving parts.
4. Walls:
   • Focus on air leaks in walls caused by electrical outlets, switches, and gaps where walls meet the ceiling or floor.
5. Ductwork:
   • Inspect and seal joints, seams, and connections in the HVAC ductwork to prevent energy loss and improve efficiency.
6. Exterior Openings:
   • Close gaps around pipes, vents, and electrical penetrations on the exterior of your home.
7. Fireplace:
   • Seal unused fireplaces with a chimney cap or flue sealer to block drafts.
8. Garage:
   • Focus on the wall shared with the house, sealing any gaps around doors, windows, or utility penetrations.

By targeting these areas, you can maximize the benefits of air sealing, such as lower energy bills, improved comfort, and reduced environmental impact.
