Mold Remediation

Professional mold testing, removal, and prevention

Mold remediation follows EPA and IICRC S520 protocols: containment, HEPA air filtration, removal of affected materials, antimicrobial treatment, and post-remediation air quality testing. Certified remediators use negative pressure containment to prevent cross-contamination to unaffected areas.

Mold Remediation Questions

: Only laboratory testing can confirm mold species. 'Black mold' (Stachybotrys chartarum) requires chronic moisture over weeks or months to grow. However, any visible mold growth — regardless of color — should be professionally remediated. Do not try to identify species by appearance alone.
: Bleach kills surface mold on non-porous materials but does NOT penetrate porous materials like drywall and wood. DIY cleaning can also disturb mold and release thousands of spores into your air. For areas over 10 square feet, the EPA recommends professional remediation.
: Coverage depends on the cause. If mold resulted from a covered water damage event (burst pipe), most policies cover remediation as part of the claim. If mold resulted from gradual leaks or lack of maintenance, most policies exclude it. Document the water source and timeline.
