Crawl space moisture is a serious issue for many homeowners in Charleston SC. High moisture levels, which are usually caused by vapor from ground moisture, can result in a range of problems, including rot, rust, mold, and pest infestations. That’s why it’s so important that all crawl spaces in Charleston have an adequate vapor barrier in place.
Whether your home is missing a moisture barrier or you’re concerned that an existing moisture barrier is compromised, the team at Crawlspace Medic® can help. Below is a brief overview of why a moisture barrier is so important for your crawl space, along with your options for vapor barrier installation in Charleston.A vapor barrier or moisture barrier is a layer of thin plastic sheeting that prevents water vapor from entering your crawl space in Charleston. An effective vapor or moisture barrier will keep moisture in your crawl space at a healthy level, preventing damage and health concerns associated with high moisture levels.
Most crawl space problems can be traced to high moisture levels. Rotting wood and rusting pipes can be traced directly to moisture issues, while mold and pest infestations are both made more likely by excess moisture.
Given South Carolina’s humid climate, it’s important that all crawl spaces in Charleston have an effective moisture barrier in place. To see if you already have a moisture barrier, simply check whether there is plastic sheeting underneath your home. If you don’t see plastic sheeting, your home needs a moisture barrier installed.
Even if you already have a vapor barrier, your crawl space in Charleston might still have moisture problems and installation is likely not up to current building codes*. Most barrier installations do not include taping seams and therefore are not up to code. This could mean that your existing barrier is damaged or insufficiently thick for your crawl space. The minimum thickness for a moisture barrier is 6 mil, at which level a new barrier will block mild to moderate vapor levels. However, a 6 mil barrier will struggle with high vapor levels, and it will be vulnerable to wear and tear over time.
If you need a new moisture barrier, or you’re concerned that your existing barrier isn’t working as well as it should, we suggest calling the team at Crawlspace Medic®. We offer crawl space inspection and vapor barrier installation services throughout Charleston, as well as in nearby communities like North Charleston, Summerville, Mt Pleasant, James Island, or Isle of Palms.

Our typical moisture barrier installations include a 10 mil polyethylene barrier with taped seams and spiked in place, which is more effective and long-lasting compared to 6 mil barrier.
