Crawl space moisture or standing water? Dit is wie je moet bellen
Excessive moisture or standing water in a crawl space is a hidden problem that affects indoor air quality, structural integrity, and energy efficiency throughout the entire home. Because warm air rises, up to 50% of the air you breathe on the first floor originates from the crawl space — carrying mold spores, musty odors, and humidity with it (the so-called stack effect). Common causes include poor grading that directs rainwater toward the foundation, missing or damaged vapor barriers, clogged foundation vents, plumbing leaks dripping onto the ground below, and high water tables. Persistent moisture rots wooden floor joists and subfloor sheathing, attracts termites and carpenter ants, and can cause hardwood floors above to buckle or cup. A basic vapor barrier installation (6-mil polyethylene over bare dirt) costs $1,500–$4,000 for an average crawl space. Full encapsulation with a 20-mil liner, dehumidifier, and sealed vents runs $5,000–$15,000 but provides the most complete solution. Addressing grading and gutter drainage outside the foundation is equally important to stop water from entering in the first place.
