Mold Remediation
Mold Remediationin Vancouver, WA & Portland Metro.
Pacific Northwest humidity makes mold inevitable when there's a moisture source. We find the source and remove the mold safely.
Mold isn't a cleaning problem — it's a moisture problem. Bleaching surface growth without identifying and stopping the moisture source guarantees regrowth within weeks. ONA Restoration is IICRC AMRT-certified and follows the S520 standard for assessment, containment, and remediation.
Assessment first, demolition second
We start with a moisture investigation to find the source: roof leak, plumbing failure, foundation seepage, condensation, or undetected slow leak. Without solving that, remediation is wasted money.
For larger jobs and insurance claims we coordinate third-party Indoor Environmental Professional (IEP) testing both before and after remediation. The pre-test scopes the work; the post-test verifies clearance independently.
Safe remediation
Affected areas are contained with poly sheeting and negative-air HEPA machines so spores aren't pushed into clean parts of the home. Non-salvageable porous materials (drywall, insulation, carpet pad) are removed and bagged inside containment. Framing and structural materials are HEPA-vacuumed, treated with EPA-registered antimicrobials, and verified dry.
Containment stays up until clearance testing passes. Then reconstruction restores everything we removed.
Process
How the job runs.
01
Inspection & moisture mapping
Identify the moisture source and the extent of contamination.
02
Third-party testing (recommended)
Independent IEP sets the scope and writes the protocol.
03
Containment & filtration
Poly barriers, negative air, HEPA scrubbers, decontamination chambers.
04
Removal & cleaning
Non-salvageable porous materials removed; framing HEPA-vacuumed and treated.
05
Drying & moisture control
Underlying moisture source repaired or rerouted. Area dried to standard.
06
Clearance & reconstruction
Post-remediation verification, then rebuild.

FAQ
Mold Remediation — FAQ
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.
