How to Verify Your Portland Mold Contractor — Before You Sign Anything
Oregon has no mold-specific contractor license. Any contractor performing mold remediation must hold a valid CCB license — but a company can legally call itself a “mold specialist” with nothing more than a basic CCB. This guide gives you the exact steps to verify credentials before work begins, in under 5 minutes.
Quick Answer: To verify a Portland mold contractor, go to oregon.gov/ccb and search by company name or license number. Oregon has no specific mold license — CCB (Construction Contractors Board) licensing is the primary regulatory credential. Always verify before signing. Takes under 2 minutes. Also verify professional mold remediation training and verification at the certification body’s verification portal. Never hire a contractor who cannot provide their CCB number on the spot.
Five Steps to Verify Any Portland Mold Contractor
Verify the CCB License at Oregon.gov
Go to oregon.gov/ccb → “Verify a License.” Search by business name, CCB license number, or owner name.
What a valid listing shows: License number, business name and address, license type, license status (must say Active), bond status, insurance status, and any registered complaints or disciplinary actions.
Look for the Restoration Services Contractor endorsement. This is the CCB license type most specific to mold remediation and water damage work. General Contractor licenses are also valid — but Restoration Services is the category specifically created for this work.
Request a Certificate of Insurance
CCB licensing requires insurance, but the status on the database reflects what was reported at licensing renewal — not necessarily today. For any significant job, ask the contractor to provide a Certificate of Insurance from their insurer with you listed as certificate holder.
- General Liability: minimum $100K per occurrence for residential work
- Workers’ Compensation: confirms employees are covered (you may have liability for injuries otherwise)
- Certificate holder: your name and address listed — insurer notifies you if policy is cancelled
Verify the professional training body Certification
The the industry professional training body issues the mold remediation specialist certification certification for mold work. Verify at the certification body’s verification portal using the company name.
Certified Firm listing: means the company holds current professional mold remediation training and verification and commits to hiring professionally trained technicians. Individual mold remediation certification means a specific technician has completed the training and exam. Ask which technicians will be on your job and whether they hold mold specialist certification.
Check CCB Complaint History
The CCB database includes all complaints filed against a contractor. Review the complaint history before hiring.
- A single old resolved complaint does not disqualify a contractor — disputes happen in every trade
- Multiple unresolved complaints, or complaints about incomplete work in the same category as your job, are significant
- Recent complaints about mold remediation or failure to correct problems deserve direct inquiry
Ask These Six Questions Before Signing
- “What is your CCB license number?” — Any legitimate contractor answers instantly
- “Do you hold a Restoration Services Contractor endorsement?”
- “Are the technicians on my job mold specialist certification-certified?”
- “Can you provide a Certificate of Insurance listing me as certificate holder?”
- “Will you provide a written, itemized estimate before work begins?”
- “Who performs the post-remediation clearance testing?” — Must be an independent third party, not the remediator
Red Flags That Should Stop the Conversation
These are not opinions — they are documented patterns in the Portland mold market that result in homeowners paying thousands for work that fails or was never necessary.
⚠ No CCB License
Any contractor performing mold remediation in Oregon requires a valid CCB license. No exceptions for scope or price. “I don’t need one for this work” is false.
⚠ Cannot Produce Insurance Certificate
Their policy may be lapsed. You may have personal liability for injuries on your property. Walk away.
⚠ “Free Inspection” from a Remediation Company
This is a sales call, not an independent assessment. The conflict of interest is structural and well-documented in Portland. Use separate companies.
⚠ Fogging-Only Quote Presented as Full Remediation
Dry fogging without physical removal and HEPA vacuuming is not full professional remediation standard compliant. It will not pass independent clearance testing. One Portland homeowner called it “an absolute scam — no HEPA vacuuming, no wiping.”
⚠ Verbal Quote Only
Legitimate contractors give written estimates. If they will not put it in writing, ask yourself why.
⚠ Pressure to Sign Immediately
“The price goes up if you wait” has no technical basis. Mold does not urgently escalate in the hours it takes to get a second opinion.
Contractor Verification FAQ
Does Oregon require a specific mold removal license?
No. Oregon has no state mold remediation license. CCB licensing in an appropriate category (Restoration Services Contractor is most specific) is the required regulatory credential. Professional certifications like the professional training body mold specialist certification are industry voluntary standards — they are not required by Oregon law but are the strongest indicator of trained, professional work.
What is the industry professional remediation standard and why does it matter?
full professional remediation standard is the industry’s professionally recognised standard for mold remediation. It specifies containment, physical removal of contaminated porous materials, HEPA vacuuming, EPA-registered antimicrobial treatment, and post-remediation clearance testing. Fogging alone does not meet this standard. If a contractor cannot describe their process in these terms, they are likely not following the full protocol.
What if I hired an unlicensed contractor and there is a problem?
Oregon CCB dispute resolution is only available for disputes with licensed contractors. If you hired an unlicensed contractor, your legal protections are significantly reduced and you cannot use the CCB complaint process. This is the primary practical reason to verify the license before work begins — not after.
How do I verify the professional mold remediation training and verification?
Go to the certification body’s verification portal and search by company name. A Certified Firm listing means the company currently holds certification. You can also ask the contractor for the individual technician’s mold specialist certification certificate number, which can be verified through the same portal.
