Start with conditions, not a product
Cutting into a wall or ceiling without proper containment just moves the problem into the rest of the house. Containment barriers and negative pressure have to be established and verified before the first cut is made.
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
Containment work here has to account for barrel-tile and flat built-up roofs alike, plus the salt-laden onshore breeze that keeps humidity elevated even between storms. Historic-district homes may also need extra care around original plaster and trim that a newer canal-front build simply doesn't have.
