Clearance testing in University Place is the independent check that a remediated room, crawl space or attic is clean and dry before containment comes down. The assessor reports pass or fail with readings and, where useful, lab results. Call the number on this page to be connected with a local mold inspector in University Place.

A shoreline suburb with a long wet season
University Place mixes suburban neighborhoods and business districts along a stretch of Puget Sound shoreline that runs to Chambers Bay, with Chambers Creek nearby. Homes near the water and on the slopes above it share the region's slow-drying months, when crawl spaces and wall cavities opened for mold work can stay damp for weeks.
What to do as the job ends
- Read the contract. Find the clause that defines when the job is complete. If clearance is not mentioned, ask for it in writing now.
- Choose an independent assessor. No Washington rule requires it, but Angi recommends separate companies for testing and remediation.
- Ask what will be measured. Visual check, moisture readings and, if useful, surface or air samples with an outdoor comparison.
- Keep the area sealed. Containment should stay in place until the assessor finishes.
- Stay out of the room. EPA advises people with asthma or weakened immune systems to keep away from moldy areas, so wait for the result.
- Plan the rebuild after the pass. Permits for building, plumbing or mechanical work in the city go to Planning and Development Services.

Clearance findings at a glance
| What you see | Likely cause |
|---|---|
| Water stains returning on cleaned wood | An active leak that was not repaired |
| Readings dropping slowly over several days | Normal wet-season drying; more dehumidifier time |
| Debris along the floor edge of containment | Final cleaning skipped or rushed |
| Surface swab still shows growth | Missed spot that needs more cleaning or removal |
Cost factors
Angi's 2026 national data puts a surface or swab test at $200 to $300 and a basic air test at $250 to $350. HomeGuide's 2026 national figures show lower per-sample prices, with air samples from $100 to $300. Expect the total to rise with the number of areas checked, tight crawl space or attic access, and any retest. Ask whether a written report with photos is included or extra. If the area fails, a second visit adds to the cost, so settle in the remediation contract who covers re-cleaning and the retest. L&I's Hire Smart guidance also suggests paying in phases, and a passed clearance is a natural point to release the last payment.
