Mold Testing in Kenmore, WA

What the call leads to

You'll be put in touch with an independent local inspector or mold company. We are a referral service, not a mold company. Share what you have noticed: an odor, staining, a recent leak, or symptoms that ease when you leave the house.

Good testing follows an inspection. The tester checks moisture with a meter in the suspect rooms and around windows, plumbing and exterior walls, then decides where samples will tell you something new. Air samples are compared with an outdoor sample taken the same day, because EPA has set no federal limits for mold spores and outdoor air always carries some. Swabs or tape lifts answer whether a mark is growth or staining.

What sets the price

Sample count matters most, followed by home size, attic and crawl space access, and lab speed. National ranges from HomeGuide's 2026 data: air samples $100 to $300 each, surface samples $50 to $200, bulk samples $100 to $350. Angi's 2026 national data puts a full air and surface test at $250 to $500. Ask what is included before you book.

Kenmore's setting

Kenmore is a Northshore suburb where the Sammamish River flows into Lake Washington, home to Kenmore Air Harbor, Log Boom Park and Saint Edward State Park. King County says the river generally stays within its banks from Woodinville down to the lake, so river flooding is not the usual story here. The usual story is the climate: long, gray, wet months, homes closed up against the cold, and condensation on windows and cold exterior walls. Lakeside lots and wooded slopes in areas like Inglewood, Arrowhead and Kenlake Vista can add shade and slow drying.

If a test leads to repairs, Kenmore Development Services has permit and building inspection staff, and the city's Code Compliance Officer takes non-emergency concerns through its Report a Concern portal. For health questions, Public Health - Seattle & King County consults on indoor air quality and mold.

Preparing for the visit

• Skip cleaning or spraying the suspect spot beforehand.
• Keep the house closed for about 24 hours.
• Turn off fans and air purifiers in rooms to be sampled if asked.
• List when the smell is strongest and any history of leaks.
• Ask whether the tester also sells removal; Angi recommends using separate companies.
