Here at SERVPRO our goal is to always attempt to restore first, and if necessary, replace building materials once decided salvageable. In certain situations however, we use our state-of-the-art drying equipment like the Injectidry System to target hard to dry areas such as wall cavities behind drywall. Instead of cutting costly amounts of affected building material, we insert small hoses into the wall and 'inject' air into the wall cavity. In some cases, this option may prove to be the cost-effective alternative to demolition.
