Moisture Readings for Homeowners

Moisture readings in internal walls play a crucial role in maintaining a healthy and comfortable indoor environment. Understanding the ideal moisture levels is essential for preventing mold growth, structural damage, and health issues.

What Should Moisture Readings Be for Internal Walls?

Ideally, moisture readings for internal walls should be below 16%.

Measuring Moisture Content

Moisture readings can be obtained using a moisture meter. Place the pins of the meter into the wall and read the digital display. Avoid measuring near electrical outlets or plumbing fixtures, as these can give false readings.

Interpreting Readings

Below 16%: Dry, no moisture concerns.
16-20%: Slightly elevated, monitor for any further increase.
20-30%: Excessive moisture, potential for mold growth and structural damage.
Above 30%: Severe moisture problem, immediate remediation required.
