In all our years of business we have seen time and time again where customers will go through the process of waterproofing or sealing their crawl space but not sealing their crawl space vents or doors. To properly seal your crawl space we suggest covering the vents to prevent humidity, cold drafts and moisture from getting inside. This homeowner in Medford, New Jersey met with our crawl space System Design Specialist, Joe Mancini, who provided an inspection of their crawl space. Although the space had been waterproofed they were still experiencing those unwanted drafts and dampness. Joe, suggested they install vent covers to completely seal the crawl space from outside elements.
