Start with conditions, not a product
An assessment that stops at photographing visible growth misses most of the picture. A useful one traces water to its source, measures crawl space and attic humidity, evaluates how far damage extends into materials, defines containment boundaries, and specifies how the outcome will be 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
An assessment on a Lexington property should account for which construction era it falls into, since crawl-space depth and vapor-barrier practices shifted over the four decades of growth inside the 1958 boundary, and whether karst limestone drainage in that specific area is a known contributor to moisture at the site.
