Health Risks Associated with Crawl Space Issues
A damp, moldy crawl space can affect your home’s air and your family’s health. Mold spores can spread through the air, triggering allergies, asthma, and breathing issues. Symptoms include sneezing, coughing, itchy eyes, and skin rashes. High humidity can also increase dust mites, another common allergen. These conditions create an unhealthy indoor environment. Children, seniors, and those with respiratory problems are especially at risk. Fixing crawl space moisture and mold problems helps protect your family and improves the air you breathe every day.
Common Crawl Space Foundation Problems We Address
Your home’s stability starts from the bottom. Our team has decades of experience identifying and correcting issues such as:
Expansive Soil
Soil that swells with moisture, putting pressure on your foundation.
Foundation Settlement
Shifting or sinking foundation due to unstable soil.
Foundation Heave
Soil pushes upward, causing floors or walls to lift and crack.
Sloping Floors
Uneven floors often signal structural shifts underneath.
Drywall Cracks
Gaps or lines in walls from foundation movement.
Stem Wall Repair
Fixing cracks or damage in crawl space perimeter walls.

Additional Crawl Space Issues We Repair
Crawl space problems can cause more than just moisture issues, they can affect your entire home. Sticky doors or windows signal shifting foundations, while failing posts and pads compromise structural support. Cracked stem walls need immediate attention to prevent further damage. Warped beams from moisture exposure weaken floor stability, and sinking piers create dangerous imbalances. Each issue threatens your home's integrity from uneven settling to expansive soil pressure. Left unrepaired, these problems lead to costly structural damage. Thomas Waterproofing's experts correct all foundation concerns, restoring safety and value to your home
