Your crawl space door is often one of the weakest points in your home’s envelope. A damaged or unsealed door can lead to:
Installing a properly insulated and sealed crawl space door helps maintain stable indoor temperatures and protects your home from costly moisture-related issues.
A tightly sealed crawl space door helps prevent air leaks, keeping heated and cooled air inside your home and reducing energy loss year-round.
Properly installed crawl space doors block outside moisture, helping control humidity levels and reducing the risk of mold and wood damage.
By sealing out damp air, dust, and contaminants from the crawl space, a new door helps improve the air circulating throughout your home.
A secure, well-fitted crawl space door helps keep rodents, insects, and other pests from entering your crawl space and home.
