Commercial Mold Remediation in Langley, WA

Langley in brief

Langley is a small city, incorporated in 1913, that calls itself the Village by the Sea. It sits at the south end of Whidbey Island about 29 miles from Seattle, overlooking Saratoga Passage, with a historic Main Street downtown, the Langley Marina and landmarks such as the Dog House building and the South Whidbey Historical Society Museum. Older commercial buildings in a wet marine climate tend to show their age at roofs, parapets, windows and shared walls between storefronts. When two businesses share a wall, a leak in one can show up as mold in the other, so cleanup sometimes needs the cooperation of a neighboring owner. Upstairs apartments over shops add bathroom and kitchen moisture to the mix.

What to do now

1. Find the moisture. Check the roof, window heads, plumbing and any wall facing the water.
2. Stop or contain the leak before cleaning anything.
3. Keep customers, staff and tenants out of the area, and close doors to keep dust in.
4. If shared heating or ventilation serves the space, shut it off until it is checked.
5. Take photos and note dates for your records.
6. Get a written scope and check the company on L&I's Verify a Contractor tool; Washington has no state mold license.

Signs and likely causes

Cost factors

Angi's Seattle cost guide reports $10 to $25 per square foot and $75 to $120 an hour for residential remediation. A downtown commercial job may cost more per square foot because of tight access, protecting neighboring businesses, after-hours work and finish carpentry in older buildings. Rebuild permits inside city limits go through the City of Langley's Community Planning and Building department rather than Island County. Island County Public Health and the state Department of Health mold page can help with health questions.
