Commercial Mold Remediation in Spokane, WA

The call usually comes from a property manager on a Monday. A tenant on the second floor found a dark stain climbing the wall behind the shower, the unit below has the same smell, and the owner wants it dealt with before the next lease is signed. That is how most commercial mold remediation in Spokane, WA begins.

We treat mold in occupied buildings for a living: multifamily, student housing, offices, medical suites, hotels and vacation rentals from downtown Spokane to Coeur d'Alene. The VaPURE process treats a unit or a floor in a single visit, usually without demolition, and an accredited third-party lab tests before and after so the owner has proof on paper. This page is about mold. Our sanitization and disinfection service for commercial spaces is a separate service with its own page.

Spokane's commercial stock splits in two. Downtown and in the older districts near the river it is brick and heavy timber from the early 1900s, with plaster interiors, flat roofs and basements that were never dry. Water gets in at parapets and roof drains, runs down inside the brick, and shows up as staining two floors below the leak. Plaster and timber usually treat well in place; the drop ceilings and drywall partitions added over the decades are what tend to come out.

Out in Spokane Valley, on the North Side, and across the state line in Post Falls and Hayden, the buildings are newer, with drywall, shared walls and tight envelopes built to energy code. Kootenai County is one of the fastest-growing parts of North Idaho, so there is a lot of it. A tight building holds heat well and holds humidity just as well, and a slow leak from a washing machine on the third floor becomes three units' problem before anyone reports it.

Coeur d'Alene, Post Falls, Hayden and Sandpoint are in our service area, and the hospitality trade there brings its own problems: high guest turnover, a bathroom in every unit, and a lakeside microclimate. Coeur d'Alene's average relative humidity peaks in January, in the mid eighties, and a building full of showers on a cold, still morning by the lake puts a lot of moisture onto cold surfaces. Idaho has no state mold license, so the lab report is how an owner there tells real remediation from a repaint.

We quote from a site visit, not a phone description. What moves the number: total square footage and number of units, how many separate treatment days the occupancy plan needs, how much material has to be removed, access to ceilings, chases and mechanical spaces, the number of lab samples, and whether the source repair is yours or coordinated through us. The site visit and consultation are free.
