Start with conditions, not a product
Removing growth without correcting whatever is feeding it — a leak, condensation, or poor drainage — just buys time until it comes back in the same spot.
Build a complete scope
- The wetting source, established before any remediation is costed
- Whether air conditioning against humid air is condensing inside the wall
- How block construction changes what containment and removal involve
- What is removed and what is cleaned, with the reasoning set out
- Verification, plus the humidity control that stops it returning
West Palm Beach context
Moisture sources here tend to trace back to AC condensate lines fighting constant humidity, roof-to-wall flashing stressed by hurricane-season wind-driven rain, or canal seepage on waterfront lots in neighborhoods like Prospect Park and Golfview Harbor. Each calls for a different fix, not one default answer.
