It usually starts small

Mold needs moisture. In Spokane that usually means spring snowmelt around basements and crawl spaces, roof leaks after snow and ice, plumbing leaks, and condensation on cold windows in winter. It grows where you can't see.

Mold spreading across a bedroom wall — **Spreading across a wall**Often a hidden leak or damp floor

Mold stains on a ceiling — **Stains on the ceiling**A roof leak or ice dam above

Mold and frost along a window frame — **Frosted windows**Winter condensation on cold frames

Mold around a bathroom extractor fan — **Round the bathroom fan**Steam with nowhere to go

Mold in a corner under a window — **Corners by windows**Cold walls collect water

Black mold along the bottom of a tiled wall — **Along tile and grout**Often small enough to clean yourself

Mold speckled across the corner of a room — **Speckles in a room corner**Poor airflow behind furniture

Water-stained wooden beams with mold — **Wet wood**Attics and crawl spaces

Know what's growing

Up close, mold is a living colony. These are the three the CDC names as the most common indoors, grown in a lab dish.

A dark green Cladosporium colony in a lab dish — **Cladosporium**Dark green to black. Window frames, bathrooms, damp fabric.

A blue-green Penicillium colony — **Penicillium**Blue-green and fuzzy. Water-damaged drywall, carpet, insulation.

A dark Aspergillus colony in a dish — **Aspergillus**Many colours. Dust, walls and heating ducts.

Several mold colonies growing together in one dish — **Usually a mix**A home rarely has just one kind.

You don't need to know which one you have. The CDC says it doesn't matter: whatever the type, remove it and fix the moisture behind it. Mold can show up as spots in many colours.

Three ways we help

Start with an inspection, not a removal quote. Companies that sell removal often inspect for free and earn more when they find a problem. Once you know what you have and where the water comes from, every removal quote is for the same job.

Good 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 clean up mold myself?

Yes, if the area is small. The EPA and the Washington State Department of Health both say you can usually clean mold yourself when it covers less than about 10 square feet, roughly a 3 by 3 foot patch. For larger areas, mold from sewage, or mold hidden in walls or ducts, hire a professional. Fix the water source first or the mold comes back.

Are you a mold removal company?

No. Mold Removal Spokane is an independent guide and referral service. We do not remove, inspect or test mold ourselves. When you request a quote, we pass your request to a local professional who serves your area so they can contact you.
