Encapsulation uses plastic liners and dehumidifiers that require drainage, sump pumps, additional electrical connections to control the moisture. The initial expense of encapsulation is out of reach for most homeowners and dehumidifiers and sump pumps will need maintenance and replacement. Average dehumidifier warranty is 3-5 years and 1 year for sump pumps. Encapsulation can VOID Termite Bonds REQUIRED by your lender. There's a BETTER WAY-
