Crawl spaces with bare dirt floors and open vents pull in humid summer air, which condenses on cooler joists. That's how a dry-looking crawl space ends up full of growth.

Wood framing with surface growth is HEPA-vacuumed and cleaned by hand or with soda or dry ice blasting, then treated where appropriate. Wood moisture content is checked before and after.
Sagging, wet fiberglass batts between joists trap moisture against the subfloor and often hide growth. They come out, leaving the space ready for new insulation or wall insulation as part of encapsulation.
A polyethylene ground cover stops soil moisture from evaporating into the crawl space. Basic barriers are 6-mil, while reinforced liners from 10 to 20 mil hold up better to foot traffic.
Sealing the space completely, with liner, closed vents, and humidity control, gives the most lasting protection against regrowth.
Water pooling on the crawl space floor needs a way out, often a perimeter drain or a crawl space sump pump, plus attention to gutters and grading outside.

Here's what some recent callers shared.

Our buyer's inspector wrote up mold on the joists, and we had three weeks to close. They cleaned the joists with soda blasting, put in a 12-mil liner, and gave us before-and-after photos for the buyer.
There was a musty smell in our living room for years, and we never thought to look under the house. Insulation was hanging down and the dirt floor was damp. After encapsulation, the smell is gone.
The oak floors began to cup near the kitchen. The contractor found subfloor readings in the low twenties. They cleaned it, added a vapor barrier, and the floors flattened out over a few months.
The photos made a big difference for me since I'm not crawling down there. The quote listed each option separately so I could do it in phases.
Usually humid outdoor air entering through vents and condensing on cooler wood, moisture evaporating from a bare dirt floor, or water pooling after storms. Plumbing leaks can add to it.
Often, yes. Rising air carries odors and spores into the rooms above, so a clean, dry crawl space improves indoor air.
A barrier covers the dirt. Encapsulation seals the entire space and controls humidity inside it.
In humid climates, open vents often bring in more moisture than they let out. Many contractors recommend sealing vents as part of encapsulation with a dehumidifier, though local building codes can affect this.
Yes. White, cottony growth on floor joists is common in crawl spaces and should be cleaned off, with the moisture problem corrected, before it damages the wood.
Price depends on square footage, access, how heavy the growth is, and how much moisture control you choose. The written quote breaks it down.
