Why It’s Important to Seal Your Crawl Space?

Sealing your crawl space is one of the best ways to stop moisture from causing trouble. When this area is left open or damp, small problems can quickly turn into bigger repairs.

Here are some common issues:

  • Moist air that leads to mold growth
  • Floors that start to sag or feel uneven
  • Higher energy bills from damp air sneaking in
  • Rust on pipes or ductwork
  • Bugs and rodents find an easy entry point

Our Expert Crawl Space Sealing You Can Trust
