If your home feels drafty, you probably need to seal it up. Air sealing is designed to prevent unwanted air from flowing out of (or into) your home. This often occurs around windows, garage doors, recessed can lights, attic openings, and crawl spaces. By addressing air leakage, you also address comfort and indoor air quality issues that might be present in your home. The idea here is to seal up the home as tightly as possible, then ventilate it properly so you know where the fresh air is coming from.
You can tackle air sealing on your own with a caulk gun and by adding weatherstripping. To make sure the job is done thoroughly, we recommend consulting a professional who can utilize different technologies to identify air leaks.
