FAQ
Mold Remediation FAQ — Gresham
Do I need a mold test before remediation?
For small, clearly visible growth from a known moisture source, often no — we can scope the work directly. For larger areas, health concerns, or insurance claims, an independent IEP test protects you and produces clearance documentation.
Is bleach enough for mold?
No. Bleach addresses surface coloration on non-porous materials but does not kill mold in porous substrates like drywall or framing, and it does not solve the moisture source. Improper DIY treatment usually makes the job more expensive later.
Does insurance cover mold?
It depends on the policy and the cause. Mold from a sudden, covered water loss is often covered up to a sublimit. Mold from long-term seepage or neglected maintenance generally is not. We help you document the cause for the claim.
