Project Timeline

Inspection & containment

2-4 hours

Inspect affected areas, determine the extent of mold growth, and set up containment barriers with negative air pressure to prevent spore migration.

Material removal

4-8 hours

Remove mold-contaminated drywall, insulation, carpet, and other porous materials. Double-bag contaminated debris for disposal. HEPA-vacuum all surfaces.

Treatment & cleaning

2-4 hours

Apply antimicrobial solution to all remaining surfaces (framing, subfloor, concrete). Wire-brush or soda-blast stubborn mold on wood framing if needed.

Clearance testing & demobilization

1-2 days

Run HEPA air scrubbers for 24-48 hours, then have a third-party inspector perform post-remediation air sampling. Remove containment and equipment once clearance is achieved.

Mold Remediation in Corte Madera — FAQ

How much does mold remediation cost?+

Small areas (under 30 sq ft) cost $500-$2,000. Moderate remediation (1-2 rooms) runs $2,000-$6,000. Large-scale remediation (multiple rooms, HVAC contamination) can cost $5,000-$15,000+.

Is mold remediation covered by insurance?+

Most policies cover mold remediation if the mold resulted from a covered water damage event (e.g., burst pipe). Pre-existing or long-term mold from deferred maintenance is typically excluded. Check your policy's mold coverage limits.

How do I know if I have a mold problem?+

Signs include visible mold growth, musty odors, chronic allergy symptoms, and recent water damage. A professional mold inspection with air sampling provides definitive answers and identifies hidden mold behind walls.

Can I clean mold myself?+

Small areas (under 10 sq ft on non-porous surfaces) can be cleaned with detergent and water. Larger areas, mold on drywall/insulation, or HVAC contamination require professional remediation with containment to prevent spore spread.
