Verify the license
In Washington State, a mold remediation specialist must hold a valid General Contractor License (Mold Remediation Specialty) & IICRC Certification. They are also required to carry liability insurance and a contractor bond to protect you.
Always verify a contractor's status before hiring. You can look them up on the official Washington State Department of Labor & Industries website using theL&I Verify tool.
- Ensure their license status shows as Active.
- Check that they have no outstanding infractions or safety violations.
- Confirm their bond and insurance amounts meet state minimums.

Offering to 'bleach it away' without addressing the underlying moisture source.
No IICRC or similar professional certification in mold remediation.
Quoting a price without conducting a visual inspection or moisture testing.
Refusing to provide post-remediation air quality testing results.
Not setting up containment barriers before beginning removal work.
Claiming all mold is 'toxic black mold' to upsell unnecessary services.
Questions to ask before hiring
- Are you IICRC-certified in mold remediation?
- Will you identify and address the underlying moisture source, not just the mold?
- Do you perform pre-remediation air quality testing and post-remediation verification?
- How do you contain the work area to prevent cross-contamination?

- Will you remove and dispose of contaminated porous materials like drywall and insulation?

Frequently asked questions in Seattle
Does homeowners insurance cover mold remediation?
Insurance typically covers mold remediation only if the mold resulted from a covered peril, such as a burst pipe. Mold from gradual moisture or humidity issues is usually not covered.
Can I remove mold myself?
Small patches (under 10 square feet) on non-porous surfaces can sometimes be cleaned by homeowners. Larger infestations, mold in HVAC systems, or mold on porous materials should always be handled by certified professionals to prevent spreading spores.
How do I know if mold is making me sick?
Common symptoms include coughing, sneezing, eye irritation, and headaches that improve when you leave the home. A professional air quality test can confirm elevated mold spore levels.
Will the mold come back after remediation?
Mold will return if the moisture source is not fixed. A certified professional will identify and address the root cause as part of the remediation process.
How long does mold remediation take?
Small isolated areas can be remediated in 1-3 days. Whole-home or extensive crawlspace remediation can take 1-2 weeks, plus time for post-remediation drying and testing.

Mold in Seattle: what local homeowners should know
Seattle's reputation for rain is well-earned — the city averages 150+ rainy days per year, creating persistent moisture conditions that fuel mold growth in crawlspaces, attics, and behind exterior walls. Homes in older neighborhoods like Wallingford, Queen Anne, and the Rainier Valley with limited ventilation and aging vapor barriers are especially vulnerable. Crawlspace moisture is one of the most common mold drivers we see in Seattle.

How we vet restoration contractors
Not every contractor in a "restoration" listing actually specializes in it. Every restoration pro in our network is checked for:
IICRC certification
The industry standard for water, fire, and mold restoration technique
Active Washington contractor license
Verified through the WA L&I Verify tool
General liability insurance
Minimum coverage confirmed before certification
Workers' comp insurance
Required for any contractor entering your property
Insurance-claim experience
Experience documenting damage and working with adjusters
We verify these directly rather than taking a contractor's word for it. Contractors who don't meet every requirement aren't added to the network, regardless of how many projects they claim to have completed.
