§ 03.09Mold remediation — TX + OH

Find the leak first. The mold is downstream.

Mold is the symptom. The moisture source is the cause. We meter every suspect surface — roof line, plumbing chase, HVAC closet, foundation grade — and confirm whether the source is still wet. Contain the room with 6-mil poly under HEPA-filtered negative pressure. Cut the substrate twelve inches past the visible colony, per IICRC S520. Treat after the demo. Rebuild with the same in-house crew. No fog-and-spray.

S520/What level we are looking at

Three categories. Three different jobs.

IICRC S520 — the reference adjusters and inspectors look at — sorts mold contamination into three tiers. We do not quote the same scope at every tier. The category we land on at the walk-through decides what gets cut, what gets contained, and what your insurance will and will not fund. Most jobs we run are Category 2.

01Category 1

Clean-water source

What you see
Recent supply-line drip caught early. Visible damp ring on drywall under 24 hours. No discoloration yet.
What we cut
Drying only — fans, dehumidifier, moisture meter to clear. Drywall stays. Insulation stays if bagged dry.
Containment
Critical-barrier poly (single layer). HEPA optional, run if dust is generated.
Drying-only response. Substrate stays in place once readings clear.
02Category 2

Visible colony, contained area

What you see
Black or green growth past the wet ring. Musty smell. Substrate still structurally sound.
What we cut
Drywall back 12 inches past the visible growth line. Insulation pulled. Soft framing replaced if punky.
Containment
Full 6-mil poly walls floor-to-ceiling. HEPA-filtered air scrubber. Negative pressure verified before any cutting.
Substrate replacement — not surface treatment. Containment up before demo starts.
03Category 3

Sewage, chronic, or wide-area

What you see
Sewage backup, multi-room growth, attic-wide contamination, or visible growth on framing itself.
What we cut
Drywall to clear substrate, insulation pulled, soft framing replaced, hard framing treated. Every porous item discarded.
Containment
Full PPE for the crew. Decontamination chamber at the entry. Daily clearance reads. Third-party PRV before rebuild.
Decontamination protocol. Third-party verification before any reconstruction begins.
H/Honest callout

Why other companies fog-and-spray. And why we will not.

Fog-and-spray is a two-hour visit and a small invoice. The substrate stays in the wall. The leak stays wet. The spores stay alive in the cavity. Everything reads clean for ninety days because the surface was sterilized; the colony underneath is still feeding. Here is the same wall, month by month, on each path.

MLD · TIMELINESame wall · two paths · nine months
  1. Day 1After the visit
    Fog & spray

    Surface looks clean, room smells different. Wall looks intact. Invoice is small.

    Source-fix & rebuild

    Containment broke down. Source dry. Substrate cut, replaced, treated, rebuilt. Job closed once meter clears.

  2. Month 1Behind the wall
    Fog & spray

    Source leak still wet. Spores in the cavity already feeding on damp insulation behind the patched drywall.

    Source-fix & rebuild

    Source dry, substrate replaced. Insulation new. No food source for spores; nothing to recolonize.

  3. Month 4Smell returns
    Fog & spray

    Musty smell back. Visible bloom returning along the original water trail. Drywall starts staining.

    Source-fix & rebuild

    No regrowth. Wall reads dry on a moisture meter. Paint film intact.

  4. Month 9The second remediation
    Fog & spray

    Homeowner calls a different contractor. Substrate now compromised — bigger demo, bigger bill, second deductible if insurance.

    Source-fix & rebuild

    Wall holds. Warranty intact. The room is just a room.

We will not run the fog-and-spray play. The reason is simple, and the reason is honest: month-four phone call is not a quote we want to write.
$/Insurance integration

What carriers fund. What they will not.

Most homeowner policies cap mold remediation at five to ten thousand dollars under a separate sublimit — a small, walled-off bucket that does not draw against your dwelling coverage. The cause has to read as sudden and accidental for the bucket to open at all. We tell you which side of that line you are on at the walk-through, before any demo is quoted.

POL · SUBLIMITHow the mold sublimit sits inside the dwelling line
Dwelling A coverageup to $400K
Dwelling A — for the structure itself
Mold sublimit — typical $5K–$10K, separate bucket

Numbers are a representative model, not a quote. Read your policy declarations for your actual sublimit; we will scope the work to it and call out the line items that exceed it before we start.

Usually coveredcause = sudden & accidental
Roof leak that started in the recent storm

Documented as sudden and accidental — wind-driven rain, hail, valley failure. Tied to the same claim as the roof scope.

Burst supply line or appliance overflow

Ice-maker line, washing-machine hose, water-heater discharge, dishwasher leak. The cause line is the trigger for coverage.

HVAC condensate failure

Cracked drain line, clogged condensate pan, secondary pan overflow. Tied to the HVAC scope on the same claim.

Sudden plumbing failure behind the wall

Slab leak, supply weep at a slip-joint, drain-line crack. Carriers fund the mold downstream when the source is sudden.

Usually excludedcause = wear-and-tear
Long-term seepage behind the wall

A slow drip that has been weeping for months or years reads as wear-and-tear. Almost every carrier excludes this language.

Chronic crawl-space humidity

Vented crawl with no vapor barrier, no dehumidifier — the moisture is environmental, not an event. Excluded as maintenance.

Condensation on cold-side drywall

Under-insulated exterior walls in winter. The water comes from the air, not from a fitting. Carrier reads this as habitability.

Anything older than the policy itself

Pre-existing damage, even mold from a leak you fixed three years ago, is not covered. We document timestamps so the file is honest.

§ 06Reach the dispatch desk

A walk-through, source-first.

The crew lead who would run the remediation walks the rooms with you. We meter every suspect surface. We name the source before quoting any demo. You leave with a real scope — diagnosis, containment, removal, treatment, rebuild — and a clear read on what your carrier will and will not fund. The walk-through is free. No fog-and-spray.
