For larger gaps, spray foam can be more effective. Ensure that the attic is properly insulated, as this also plays a crucial role in air sealing.
Sealing Windows and Doors
Check for gaps around window frames and door edges. Apply weatherstripping to movable parts, ensuring a tight seal when closed. For stationary windows, use caulk to fill in any cracks or openings.
Air Sealing the Basement and Crawl Spaces
Inspect the basement for gaps around foundation walls and where pipes enter. Use foam sealant for larger openings and caulk for smaller cracks. Ensure that crawl spaces are ventilated properly to avoid moisture issues. For related context, read what to look for in a roofing company.
