Pacific has flooded from the White River more than once, most recently when a levee breach in December 2025 affected more than 200 homes, so commercial mold work here often means rental properties and small businesses drying out and rebuilding. Remediation removes soaked materials once the building is dry and documents that the space is clean. Call the number on this page to be connected with a local mold remediation company in Pacific.

Pacific in brief
Pacific is a small city of about 7,200 people between Auburn and Sumner, roughly 25 miles from Seattle, mostly in King County with part in Pierce. The lower White River, also called the Stuck River, runs along the east side of town. In November 2006 record rain pushed the river over its banks along Pacific City Park, forming a temporary 25-acre lake. In January 2009 releases from Mud Mountain Dam caused fast flooding with almost no warning. Early on December 16, 2025, a White River levee breached, a Level 3 "Go Now" evacuation was ordered, more than 200 homes were affected and over 600 people were displaced.
Steps to take now
- Make sure the building is safe to enter and the power is off where water reached outlets.
- Start drying right away; EPA says a building that couldn't be dried in 24 to 48 hours should be treated as having mold.
- Remove wet rugs, cardboard, papers and stock that can't be saved.
- Keep children, and anyone with asthma or a weakened immune system, away from the cleanup, as EPA advises.
- Photograph water lines and damage for the insurer and the city.
- Check whether the property is in a FEMA special flood hazard area before rebuilding.

Signs and their usual cause
| What you see | Likely cause |
|---|---|
| Growth climbing drywall to a clear line | Floodwater that sat against the wall |
| Odor from under the floor | Wet crawl space soil, insulation or subfloor |
| Spotting behind cabinets and appliances | Water trapped where air can't reach |
| Mold returning after cleaning | Framing or insulation still wet inside the wall |
Cost factors
Post-flood commercial jobs are bid per building. HomeGuide's 2026 national ranges put whole-house remediation at $15,000 to $30,000 and crawl spaces at $1,500 to $4,000, and local prices vary. Height of the water line, crawl space access, the number of units, drying time and rebuild scope all move the number. The City of Pacific says repairs to flood-damaged property need building permits and/or floodplain development approvals, which come through Community Development. Before hiring, confirm the company is registered with Washington L&I as a construction contractor; the state has no mold license.
