Is moisture under your house?

Humidity + red clay = a wet crawl space
Most homes around Charlotte, Rock Hill and Columbia sit on vented crawl spaces. Every summer, hot, humid air flows through those vents and condenses on cooler floor joists and ductwork. Red clay soil holds rainwater for days and releases it under the house.
The result: fungus growth on wood, wet and falling insulation, musty smells drifting into your living space, pests, and floors that feel soft or cold. Since air from the crawl space rises into the home, what happens down there affects the air you breathe upstairs.
Crawl space encapsulation breaks that cycle by sealing the space from outside air and ground moisture and controlling humidity with a dehumidifier.

Wetlock came on site and developed a plan that worked for our issue. They gave me a quote that we could handle. The work was completed and it was as if nothing had happened. Everything was clean. They are a team that I will work with again. Give them a call, you will not go wrong. Thank you Wetlock.JeanetteSouth Carolina

What is crawl space encapsulation?
Crawl space encapsulation seals the floor, walls and vents of a crawl space so ground moisture and humid air stay out. Wetlock offers full encapsulation with foam board, a sealed crawl space with wall liner, and a starter system.
How do I know if my crawl space has a moisture problem?
Common signs include a musty smell indoors, fungus growth on floor joists, sagging or wet insulation, standing water after rain, soft or cupping floors, condensation on ducts, and higher humidity indoors during summer.
Why are crawl space problems so common in the Carolinas?
Hot, humid summers push moist air into vented crawl spaces where it condenses on cooler wood and ductwork. Red clay soil common across the Charlotte region holds water after storms, adding even more moisture under the house.
Do you give written proposals?
Yes. Every proposal is written and itemized so you know exactly what is included and what it costs before any work begins.
