How to Check for Moisture Under My House?

Moisture under your house can cause significant damage if left unchecked. Here are some tips on how to check for moisture and what to do if you find it:

Signs of Moisture Under Your House

  • Sagging floors
  • Musty smell
  • Visible mold or mildew
  • Wood rot
  • Damp crawlspace or basement

Checking for Moisture

  • Visual Inspection: Inspect your crawlspace or basement for signs of moisture, such as water stains, mold, or mildew.
  • Moisture Meter: Use a moisture meter to measure the moisture content of the wood and concrete in your crawlspace or basement. A reading above 15% indicates excessive moisture.
  • Condensation: Look for condensation on pipes, walls, or the floor. This indicates high humidity levels, which can lead to moisture problems.

Addressing Moisture Issues

If you find moisture under your house, it's important to address the issue promptly. Here are some steps you can take:

  • Identify the Source: Determine the source of the moisture, whether it's a leaking pipe, poor ventilation, or drainage issues.
  • Fix the Source: Repair any leaks or plumbing issues, and improve ventilation by installing vents or a dehumidifier.
  • Waterproof the Crawlspace or Basement: Apply a waterproofing sealant to the walls and floors to prevent moisture from entering.
  • Improve Drainage: Install gutters and downspouts to direct water away from your house, and grade the soil around your foundation to prevent water from pooling.

By following these steps, you can check for moisture under your house and take steps to address any issues promptly, preventing potential damage to your home.
