When should you book a mold inspection?
- There is a musty smell and you cannot see where it comes from.
- You had a leak, a flood, a burst pipe or a wet basement.
- You see water stains, peeling paint, or dark spots on walls, ceilings or window frames.
- You are buying a house with a basement, a crawl space or a history of water problems. See our home buyer guide.
- Someone in the home has allergy or breathing symptoms that ease when they are away.
- Mold was removed and you want proof the job worked.
If you can clearly see a small patch of mold (under about 10 square feet) and know why it is there, you may not need an inspection at all. The EPA and the Washington State Department of Health say you can usually clean a patch that size yourself.
What a mold inspector checks
- Talks to you about smells, leaks, symptoms and the history of the house.
- Looks through the home, focusing on basements, crawl spaces, attics, bathrooms, kitchens, windows and around the furnace.
- Measures moisture with a moisture meter and often a thermal camera, to find wet spots behind walls and under floors.
- Takes samples if they help, usually an indoor air sample plus an outdoor sample to compare against. See mold testing.
- Writes a report with photos, where the moisture is, what caused it and what to fix.

Independent inspector or removal company?
Choose an inspector who does not also sell mold removal. Companies that do both often offer free inspections and earn more when they find a problem. An independent inspector gives you an unbiased report you can take to any removal company, and can come back afterwards to confirm the work is done.
Questions to ask before you book
- Do you also do mold removal, or inspection only?
- Which mold certification do you hold (for example ACAC, IICRC or NORMI)?
- Is the lab fee included, and how many samples does the price cover?
- Do you use a moisture meter and a thermal camera?
- Will I get a written report with photos, and how soon?

Common questions
How much does a mold inspection cost in Spokane?
Most Spokane mold inspections with lab testing cost about $300 to $600. Published local prices we checked in October 2026 start at around $425 for a standard inspection with one indoor air sample, an outdoor comparison sample and lab fees, with each extra sample about $100, so a typical three-sample job is about $525. A visual inspection without lab samples costs less. Always ask whether the lab fee and the written report are included.
Is mold testing worth it?
Mold testing is worth it when you suspect mold you cannot see, after a leak or flood, before buying a house, or to confirm a cleanup worked. If you can already see or smell mold, the Washington State Department of Health says sampling is usually not needed: the priority is finding the moisture and removing the mold.
Can I do my own mold inspection?
You can do a first check yourself: look and sniff in basements, crawl spaces, attics, under sinks and around windows, and look for water stains or peeling paint. Hidden mold behind walls or under floors usually needs a professional with a moisture meter or thermal camera to find.
How long does a mold inspection take?
A typical home inspection takes about one to three hours on site, depending on the size of the house and how many areas need checking. If air or surface samples are taken, lab results usually come back within a few business days.
Should I get a mold inspection before buying a house in Spokane?
Yes, if the house has a basement or crawl space, a musty smell, water stains, or a history of leaks or flooding. A standard home inspection notes visible moisture problems but is not a full mold assessment. Book it inside your inspection period so you can still negotiate or walk away.
What certifications should a mold inspector or removal company have?
Ask which mold certification they hold, for example from ACAC, IICRC or NORMI, and how many mold jobs they have done. Washington licenses home inspectors, but mold credentials are mostly private certifications. A removal company that tears out drywall or flooring should also be a registered contractor with Washington Labor & Industries, and the EPA advises checking references and asking them to follow EPA or IICRC guidance.
Are free mold inspections a good idea?
Be careful with free inspections. They are usually offered by companies that also sell mold removal, so they make money when they find a problem. An independent inspector who does not do removal has no reason to oversell the job.
How do I know if there is mold in my crawl space?
A musty smell inside the house, visible fuzzy or dark growth on wooden joists, damp insulation, standing water or condensation are the usual signs. Spokane crawl spaces often get damp from spring snowmelt, so they are one of the first places an inspector checks.
Why do Spokane homes get mold?
Mostly from water getting in or condensing: spring snowmelt and poor drainage around basements and crawl spaces, roof leaks after snow and ice, plumbing leaks, and condensation on cold windows and walls in winter. Mold needs moisture, so the fix always starts with the water source.
