Frequently Asked Questions

Is the inspection really free?

Yes. We inspect your crawl space or basement, take photos of what we find, explain the cause of the problem and give you a written proposal. There is no charge and no obligation.

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.

How long does a typical project take?

Most crawl space encapsulations and drainage projects take one to three days. Larger basements or combined drainage and encapsulation projects can take longer. Your proposal lists the expected timeline.

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.
