Mold remediation after water intrusion starts with source identification and moisture mapping. In Spokane homes we often find hidden growth behind baseboards or in crawl spaces once river flooding or roof leaks saturate insulation. We use moisture meters and thermal imaging to locate every wet pocket before any demolition, because cutting drywall without full drying simply moves the problem to another wall cavity.
Containment is critical in older Spokane stock with plaster and lath. We erect negative-air barriers with HEPA filtration so spores do not migrate into living areas during removal. Porous materials like carpet pad and saturated drywall are bagged on site; non-porous surfaces receive antimicrobial treatment followed by HEPA vacuuming. Post-remediation verification includes air sampling and visual inspection to confirm spore counts match outdoor baselines before any reconstruction begins.
Edge cases we see regularly include HVAC systems that have pulled spores through ductwork after basement flooding. We isolate and clean coils and plenums separately, then recommend filter upgrades. Homeowners should never attempt bleach cleaning on structural wood; it only masks growth and leaves hidden roots that reactivate the next time humidity spikes.

How it works
- 1
Inspection and Moisture Mapping
We locate every moisture source with meters and imaging, document affected materials, and create a written scope before work begins.
- 2
Containment Setup
Negative-pressure barriers and HEPA air scrubbers isolate the work zone so spores stay out of occupied spaces.
- 3
Removal and Cleaning
Porous materials are removed; hard surfaces are cleaned, treated, and HEPA-vacuumed to eliminate visible growth and roots.
- 4
Drying and Verification
Industrial drying equipment brings moisture levels to industry standards, followed by post-remediation air sampling.
Pricing
Pricing varies by square footage, hidden growth, and HVAC involvement. We provide written estimates after inspection.
