Mold Removal in Pacific, WA

Between Auburn and Sumner

Pacific is a small riverside city about 25 miles south of Seattle, between Auburn and Sumner. Most of it is in King County, with part in Pierce County, so county services depend on the address. The lower White River, also called the Stuck River, runs along the east side of town past Pacific City Park.

A river with a history

Pacific has flooded repeatedly:

• November 2006: record November rains pushed the White River over its banks along Pacific City Park, creating a temporary 25-acre lake.
• January 2009: water releases from Mud Mountain Dam caused rapid flooding with virtually no notice.
• December 2025: a White River levee breached overnight, flooding a large part of the city. Police and Valley Regional Fire ordered a Level 3 "Go Now" evacuation; more than 200 homes were affected and over 600 people displaced.

Floodwater soaks everything below the waterline: drywall, insulation, flooring, cabinets and the contents of crawl spaces. EPA says that if a flooded home couldn't be dried within 24 to 48 hours, mold growth should be assumed. Porous materials that stayed wet usually have to go, and children should stay out of the cleanup.

Cleaning up in the right order

1. Wait until the city says it's safe to go back in, and document damage with photos.
2. Remove standing water and wet porous materials; don't run a furnace or ducts that took in water until they're checked.
3. Dry the structure with fans and dehumidifiers, and confirm with moisture readings.
4. Get permits or floodplain approvals before rebuilding.

Permits and floodplain approvals

The City of Pacific tells residents to check whether their property is in a flood-prone area or a FEMA special flood hazard area, and says repairs to flood-damaged property need building permits and/or floodplain development approvals from the city. It also publishes guidance on cleaning up damaged structures in the floodplain and notes that homeowners insurance doesn't cover floods. Community Development handles permit applications and code enforcement through its building inspector.

Renters should give the landlord written notice of leaks or water damage; Washington law sets times for the landlord to start repairs. Public Health - Seattle & King County offers indoor air quality and mold consultations for health questions.

Hiring after a flood

Washington has no mold license or certification. After big floods, unfamiliar companies show up; check L&I contractor registration on the Verify a Contractor tool, get written bids, and avoid paying everything up front. Your call connects you with an independent local remediation company.
