Check the foundation for efflorescence

How to Check for Moisture Under My House?

Efflorescence, a white, powdery substance, can indicate moisture problems beneath your home. Here's how to check your foundation for efflorescence, a sign of potential moisture issues:

Visual Inspection

Examine the foundation: Look for white, powdery deposits on concrete surfaces, bricks, or mortar joints.
Check for cracks or gaps: Inspect the foundation for openings that may allow moisture to enter.
Survey the crawlspace: If accessible, crawl beneath your home and check for signs of dampness, mold, or musty odors.

Touch Test

Feel the foundation: Touch the foundation surfaces to detect any dampness or coolness, indicating potential moisture.

Moisture Meter Test

Use a moisture meter: A moisture meter can provide a more precise estimate of moisture levels in the foundation.
Insert the probes: Insert the moisture meter probes into different areas of the foundation to measure moisture content.

Additional Considerations

If you detect efflorescence or any other signs of moisture, consult a qualified contractor for further evaluation and potential repairs to prevent water damage to your home.
