The white or gray fuzz on crawl space joists and subfloor is usually mold or a wood-decay fungus feeding on damp wood. It thrives in the warm, humid, poorly ventilated conditions common under South Mississippi homes. Beyond the musty smell that drifts up into the living space, it slowly breaks down the wood — which is how untreated crawl spaces end up with soft joists, rot, and sagging floors.
Removal means cleaning the affected wood, applying an antimicrobial treatment, and clearing contaminated debris and old plastic from the crawl space. But mold always comes back if the moisture stays, so the second half of the job is drying the space out — a vapor barrier, sealed vents, drainage for any standing water, and a dehumidifier or full encapsulation to hold humidity low for good.
Usually $1,500 to $5,000, depending on how much wood is affected, crawl space size, and any joist repair. Fixing the moisture source is part of a lasting job.
