If you smell it in your living room, it's coming from your crawl space. We eliminate odors at the source.
High humidity weakens wooden floor joists. Encapsulation protects your home's structural integrity.
Charleston's 80%+ humidity breeds mold. We keep your under-home environment below 60% relative humidity.
Living in the Lowcountry presents a unique architectural challenge. Because of our high water table and specific geological makeup, your crawl space is more than just a storage area—it is an environmental engine that dictates the health of your entire home.
The South Carolina “Clay Soil” Trap: Unlike the sandy soils of the coast, much of Summerville and West Ashley sits on dense, South Carolina red clay. This soil acts like a sponge, retaining groundwater long after a storm has passed. This moisture sits directly against your wooden floor joists, creating a constant “vapor drive” that leads to structural wood rot and sagging floors.
The “Stack Effect” (Your Home’s Breathing Cycle): Many homeowners don’t realize that up to 50% of the air you breathe in your living room originates in your crawl space. Due to a physical phenomenon called the Stack Effect, warm air rises and escapes through your attic, creating a vacuum that pulls damp, mold-spore-laden air from the crawl space up through your floorboards and into your lungs.
Neutralizing the Threat: By fully encapsulating your crawl space with a 20-mil vapor barrier and a dedicated dehumidification system, we break the cycle of the Stack Effect. We transform your home’s underside from a damp breeding ground for “Dirty Sock Syndrome” into a clean, dry, and conditioned environment that protects both your family’s health and your home’s resale value.
We use antimicrobial treatments to kill biological growth on floor joists.
A heavy-duty, puncture-resistant shield that blocks ground moisture forever.
Rodents love damp dark spaces. Encapsulation creates a physical pest-proof seal.
Sized specifically for Charleston humidity to maintain crisp, dry air.
Excess moisture causes expensive hardwoods to warp and buckle.
Excess moisture causes expensive hardwoods to warp and buckle.
An unsealed crawl space forces your AC to fight damp air, increasing utility costs.
Sealing vents prevents the "tug-of-war" between your HVAC and the SC heat.
Typically between $5,000 and $15,000, depending on square footage, existing mold levels, and whether a sump pump or French drain is needed for groundwater management.
We install an "Inspection Gap" (a clear strip at the top of the liner) so pest control companies can easily inspect for termite mud tubes, keeping your bond fully intact.
Yes. Due to our local dew points, a vapor barrier alone isn't enough to prevent condensation on your ductwork. A dedicated SaniDry or equivalent dehumidifier is essential.
