### Moisture Mapping Moisture mapping is a reliable and effective method for identifying areas of moisture intrusion within a building structure. It involves utilizing specialized moisture meters and thermal imaging cameras to meticulously create a comprehensive map of moisture levels throughout a property. ### Detection Methods Multiple methods are employed for moisture mapping: - **Moisture Meters:** Pin-type or non-invasive moisture meters measure electrical conductivity, which increases with moisture content. - **Thermal Imaging:** Infrared cameras detect temperature variations, revealing areas of moisture accumulation. - **Surface Mapping:** Visual inspections and moisture stains indicate potential sources of moisture intrusion. ### How to Check for Moisture Under Your House? Below-house moisture can lead to structural damage, mold growth, and health hazards. To check for moisture under your house: - **Inspect Foundation Walls:** Look for cracks, efflorescence (white powdery deposits), or water stains. - **Check Crawlspace:** If accessible, inspect for standing water, dampness, or mold. - **Observe Plumbing:** Inspect pipes for leaks or condensation, and check under sinks and appliances. - **Test Soil Moisture:** Use a moisture meter to test soil near the foundation for high moisture levels. - **Consult a Professional:** For a thorough moisture mapping report, consider hiring a certified moisture mapping professional.
