On Bainbridge Island, post-remediation clearance testing is the final inspection that shows a work area is clean, dry and free of visible growth before containment comes down. An independent assessor typically checks surfaces and moisture levels and adds lab samples when they help.

Island homes, older stock and salt air
Bainbridge Island has about 53 miles of irregular shoreline facing Puget Sound, Port Orchard Bay, Rich Passage and Agate Pass, plus Eagle Harbor at Winslow. In ZIP code 98110, about 34.5 percent of houses were built in 1979 or earlier, so plenty of homes have older framing, crawl spaces and window details that let moisture in over the years. The city also warns that king tides can bring local tidal flooding in some areas starting around 13 feet above mean lower low water, higher during windy storms.
What to do now
- Ask the remediation company to leave containment in place. Plastic walls and air filtration should stay until the area passes.
- Hire the assessor separately. Angi recommends that testing and removal be done by different companies, so the judgment is neutral.
- Agree on what counts as a pass. No visible growth or settled dust, dry framing and, if sampled, results that compare well with outdoor air.
- Keep water sources fixed. If the job followed a tidal or storm event, confirm the entry point was repaired before anyone signs off.
- Collect the documents. Remediation scope, before-and-after photos, the clearance report and invoices belong in one file.
Reading the results
| What you see | Likely cause |
|---|---|
| Salt or tide line on lower framing | Seawater or storm water reached the wall; extra drying needed |
| Damp crawl space soil and wet joists | Poor drainage or vapor barrier issues outside the work area |
| Clean surfaces but high air counts inside | Fine debris still settling after removal |
| Fresh staining on window sills nearby | Winter condensation, a separate moisture source |
Cost factors
Clearance follows sampling prices. HomeGuide's 2026 national figures list air samples at $100 to $300 and surface samples at $50 to $200; Angi's 2026 national data puts combined air and surface testing at $250 to $500. The total depends on the number of rooms or cavities checked, access under the house, the outdoor comparison sample and any retest. After a pass, rebuild permits go to the City of Bainbridge Island Building Division through its online permit portal, and electrical permits go to Washington L&I.
