Start with conditions, not a product
Treating visible growth without correcting what's feeding it is a temporary fix. The plan that actually works identifies the water's entry point, accounts for ongoing crawl space and attic humidity, evaluates material damage, defines containment, and specifies how the result gets verified.
Build a complete scope
- What is wetting the space, resolved before cleaning is priced
- Whether limestone channels are delivering water from beyond the lot line
- The containment barrier and the air path while work proceeds
- The cut line between salvage and disposal, and what sets it
- Verification afterward, plus the crawl space or venting fix that stops a repeat
Lexington context
Karst limestone's irregular drainage is a recurring wrinkle in moisture-source work around Lexington: water can travel underground through solution channels in ways a standard soil survey won't predict, so correcting a moisture source here sometimes means accounting for subsurface drainage patterns that a flatter, non-karst metro area wouldn't have to consider.
