Tacoma's commercial mold work spans downtown offices, older apartment buildings on Hilltop and the North Slope, restaurants and shops, and warehouses near the Tideflats. The work has to be scoped in writing, contained so it does not spread through shared air, and checked before anyone rebuilds. Call the number on this page to be connected with a local mold remediation company in Tacoma.

Signs a Tacoma building needs attention
- Stains spreading across ceiling tiles after a stretch of rain
- Tenants on one side of a building reporting the same musty smell
- Peeling paint or soft drywall below windows on an older brick or wood-frame building
- Growth in a mechanical room, on a rooftop unit's drain pan, or around supply vents
- Wet floors at grade in a warehouse or shop after high water
Tacoma conditions
Tacoma is the South Sound's port city, wrapped around Commencement Bay with a restored downtown waterfront, the Thea Foss Waterway and a large commercial port. The city's comprehensive plan treats both the 1 percent and 0.2 percent annual-chance floodplains as flood hazard areas, expects greater flood risk on the Puyallup River, and names the West End, North End and Tideflats as more exposed to coastal flooding than inland areas. Most commercial calls, though, come from ordinary building failures: roof and parapet leaks, plumbing in stacked units, and condensation in older buildings in neighborhoods like the Stadium District and Proctor. The Tacoma-Pierce County Health Department's mold advice applies to any building: stop leaks, repair roofs and plumbing, and keep water away from foundation walls and slabs.
For rentals, tenants first notify the landlord in writing. If repairs are not made, they can file a Rental Housing Code complaint through TacomaFirst 311, and Code Compliance inspects building conditions such as leaking roofs. Owners rebuilding after removal file through the City of Tacoma Permit Center.

What it costs
Commercial jobs are bid one by one, but Angi's Seattle cost guide gives useful reference points from residential work: $10 to $25 per square foot for remediation, $75 to $120 an hour for labor, and $2,475 to $8,275 when an HVAC system is involved. Expect bids to climb with multiple work zones, lift or ceiling access, after-hours schedules, and replacement of drywall, ceilings and flooring.
What happens when you call
Your call is connected to an independent local company that handles commercial work. Most will want to see the building, measure the affected area, check moisture levels and look at the air system before writing a scope. Washington has no state mold license, so confirm the company is registered with L&I as a construction contractor. Many owners also hire a separate assessor to confirm the area is clean before rebuilding.
