What causes crawl space problems in Islip, NY?[+]
Islip's south-shore water table means crawl spaces frequently deal with standing water, high humidity, wood rot, and mold. Encapsulation — a vapor barrier system combined with a sump pump — is the permanent fix. It improves air quality throughout the house and eliminates the conditions that cause structural wood decay.
