Crawl space mold removal starts with getting under your home and seeing exactly what we're dealing with. Most crawl spaces in Saint Louis, MO run damp for months before anyone notices, and by the time you smell it upstairs, the mold has usually spread across joists, subfloor, and insulation. Our job is to clear it out completely and make sure it doesn't come back.
Homeowners usually call us after noticing a musty smell that won't go away, dark spotting on wood framing or the underside of the subfloor, or unexplained allergy symptoms that ease up when they leave the house. Sometimes it's simpler than that – a recent plumbing leak, a flooded crawl space after heavy rain, or insulation that's gone soft and damp are all signs mold is likely already growing, even if you can't see it yet.
We start every job with a hands-on inspection, not a guess. That means checking moisture levels with a meter, looking at vapor barrier condition, and tracing where the water is actually coming from – a plumbing leak, poor drainage, or just humid ground air with no vapor barrier to stop it. If the source isn't dealt with first, removal is a temporary fix. Once we know what we're working with, we remove contaminated material, treat affected wood and surfaces, and run air scrubbers to clear spores from the space before we call the job done.
Cost depends on how much square footage is affected, how far the mold has spread, and how easy the crawl space is to access – a tight, low-clearance space takes longer than one you can move through freely. If we find rotted wood or a moisture problem that needs a repair, not just a treatment, we'll tell you upfront instead of quoting a number that doesn't hold up once we're under the house.
If your crawl space in Saint Louis, MO smells off or you've had recent water intrusion, don't wait on it – mold spreads fast in that kind of environment. Call (213) 871-1085 for a free inspection and we'll tell you exactly what we're seeing, no upsell.
