Start with conditions, not a product
Removing visible growth without isolating the crawl space or attic it came from just spreads spores into the rest of the house. A sound approach finds the water's entry point first, tracks humidity through the job, evaluates how deep the damage runs, seals the work zone off from living space, and checks conditions again once removal is complete.
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
Because so much of the metro was built over crawl spaces rather than basements, containment work in Lexington often has to isolate a below-grade crawl space from the living area above it, which is a different containment problem than a basement or slab-built house presents.
