Why Bleach Is a Bad Word in Restoration
When a homeowner asks, “Can’t you just spray some bleach on it?”, you know there is education to do. Bleach may remove discoloration, but on porous building materials, it often leaves the underlying mold structure and residues behind.
The bigger challenge occurs when an adjuster attempts to limit remediation to “surface cleaning” only. That approach does not align with modern remediation principles.
Dead mold is still mold
The IICRC S520 Standard emphasizes physical removal of mold contamination as the primary objective of remediation. Even if a chemical product kills mold spores, the remaining fragments and particles can still be allergenic and irritating to occupants.
You cannot fog a structure and call it remediated. Source material must be addressed.
The “sandwich” protocol for salvageable framing
For structural wood components that can remain in place, “spray and wipe” is not sufficient. A proper work sequence typically includes:
- HEPA vacuuming to remove loose spores
- Agitation or sanding to remove mold growth that has penetrated the wood surface
- HEPA vacuuming again to collect dust created during sanding
This work is labor intensive and should be estimated accordingly. (See: Why Your Xactimate Estimate Failed)
Do not cut corners on containment
Containment barriers and negative air machines are not optional add-ons. They are engineering controls that help prevent cross-contamination during sanding or the removal of affected materials. If you do not bill for them, you are absorbing the cost of protecting the rest of the structure.
Document your containment setup before you take it down. (See: The Golden Rule of Claims)
Post-remediation verification matters
Post-remediation verification (PRV) by a qualified third party is recommended before containment is removed. If the area fails clearance after plastic is taken down, you may end up re-cleaning a much larger area at your own expense.
The bottom line
Mold remediation is centered on the physical removal of contamination. If the estimate does not account for the labor, engineering controls, and verification necessary to complete that work, then it does not accurately reflect the scope of professional remediation.
