Crawl Space Repair & Encapsulation in Charleston

As a homeowner in Charleston, you know that the area is no stranger to humidity and rain, but you may not realize how these common occurrences affect your crawl space. Most crawl spaces use wooden beams to support the floors of your home. When excess moisture infiltrates your crawl space, it can cause these beams to experience wood rot or mold – putting your entire home at risk. Additionally, moisture in your crawl space can lead to increased energy bills, damaged insulation, and pests.  

Despite these many problem signs, Mount Valley Foundation Services has the tools and expert knowledge to keep water out of your Charleston crawl space. Crawl space repair and encapsulation involves the installation of a dehumidifier, vapor barrier, support beams, sump pump, vent covers, and more to completely waterproof your crawl space. We’ve been helping homeowners in North Carolina and South Carolina keep their crawl spaces dry since 1986, and we’re ready to help you too!

Crawl Space Problem Signs in Charleston

As mentioned, excess moisture in your crawl space leads to many problem signs below your home, especially during the rainy and humid summers in Charleston. Wood rot and mold can form on wooden beams which causes them to break down over time. As the wooden beams break down, your home may suffer from sagging floors. Mold spores may spread into your home, causing potential health problems and more mold growth. High moisture can also lead to increased energy bills as humidity travels from your crawl space and into your living area. Furthermore, the Charleston humidity attracts all kinds of pests – from insects to rodents.

Causes of Crawl Space Damage in Charleston

Obviously, moisture is the main cause of crawl space damage in Charleston, but how exactly does so much water get below your home? First, open crawl space vents allow humid air to easily penetrate the crawl space. Ineffective vapor barriers might also cause more damage if installed improperly. Another issue is over spanned floor joists that occasionally occur during construction. Essentially, these are beams that are built too far apart and are unable to support the weight of your home. Understanding these causes is the first step in repairing them!
