If you’ve been struggling with air leaks and drafts in your home, it’s important to consider the role of your crawl space. A crawl space is an area beneath your home that is typically designed to provide access to pipes and other utility systems. However, if it’s not properly sealed, it can create an entry point for outdoor air to infiltrate your home. It can be challenging to determine if your crawl space is contributing to this issue, but there are several ways to tell. One approach is to conduct an “eyeball test.” This method involves inspecting your crawl space visually to look for any signs of air infiltration. For example, you might notice that there are gaps or cracks in the walls or floor, or that there are areas where insulation is missing or damaged. These can all be indications that outside air is finding its way into your home through your crawl space. Another way to tell if your crawl space is contributing to air leaks is to conduct a “floor check.” This involves walking around your home and feeling for drafts or cold spots near the floor. If you notice that certain areas of your home feel colder than others, or if you feel a draft coming up from below, this could be a sign that your crawl space is contributing to the problem. Finally, it’s always a good idea to seek professional help if you’re concerned about air leaks in your home. A professional contractor can conduct a thorough inspection of your crawl space and identify any areas where air might be getting in. They can also recommend solutions for sealing your crawl space and preventing future air leaks.
