How to Check for Moisture Under My House

Check your crawlspace or basement for visible signs of moisture. Inspect the floor, walls, and support beams for dampness, mold, or rot. Check for any leaks in pipes or appliances, and seal any gaps or cracks where moisture can enter.

Use a moisture meter to measure the moisture content in the air and in building materials. High readings indicate excessive moisture levels. Insert the probes into the ground or building materials to measure the moisture level:

  • Below 16%: Acceptable moisture level.
  • 16-20%: Slightly elevated moisture level, monitor and inspect regularly.
  • Above 20%: High moisture level, take immediate action to address the source of moisture.

Take steps to address any moisture issues promptly to prevent damage to your home and ensure the health and well-being of your family.
