Step-by-Step Basement Moisture Assessment

Start with a visual inspection. Look for water stains on walls and floors. Check for standing water after heavy rain. Use a flashlight to examine corners and behind stored items where mold often grows unseen.

Test humidity levels with a hygrometer. Readings above 60% indicate conditions favorable for mold growth. Portland basements often register 70% or higher during winter months without proper dehumidification.

Check your sump pump operation. Pour water into the sump pit and verify the pump activates automatically. A failing pump allows water to accumulate during Portland’s frequent storm events.
