Mold Inspection in Redmond, WA

Does the Sammamish River put my Redmond home at risk?

For most homes, not directly. Downtown Redmond lies just north of Lake Sammamish, and the Sammamish River leaves the lake at Marymoor Park and runs along the west edge of downtown. King County notes that when the river is high it can limit access to NE 95th Street and low sections of the Sammamish River Trail and back water up into stormwater facilities, and farmland between Redmond and Woodinville floods when upland stormwater can't drain. Homes near those low areas should watch for water in crawl spaces after long rainy spells. Elsewhere, on Education Hill or in Overlake, everyday moisture is the bigger factor.

My house is from the 1980s. What will the inspector look at?

The median Redmond home was built around 1984. Houses that age often have original windows, bath fans that are undersized or vented into the attic, and crawl spaces with tired vapor barriers. A good inspector checks each of these, takes moisture readings at exterior walls and around plumbing, and looks at attic sheathing for the dark staining that condensation leaves. Expect photos and a written report.

I rent. Will the city inspect for mold?

No. Redmond Code Enforcement says it doesn't oversee general property maintenance issues such as mold, pests or odors. It acts only when conditions meet the state definition of substandard or dangerous housing under RCW 59.18, and only after the tenant has notified the landlord in writing. Landlord-tenant disputes are civil matters. Start with written notice about the leak or moisture problem; this is general information, not legal advice.

A quick local note on cost

National 2026 ranges are $303 to $1,044 (Angi) and $300 to $650 (HomeGuide) for an inspection. Apartment units cost less to inspect than a large house; extra floors, tough attic access and lab samples cost more. If the report leads to rebuilding walls, Redmond's Development Services Center reviews and issues construction permits. Ask the inspector to separate what must be removed from what only needs drying and cleaning, so any removal quote you get afterward can be compared line by line.
