Mold Remediation in Bellevue, WA: Contain It, Remove It, Dry the Cause

Why Bellevue Homes Stay Damp

City rain-gauge records put average rainfall from October through April at close to 29 inches, and the gauges at higher elevations collect noticeably more than those near the lake. Months of grey, wet weather keep outdoor air humid, so a house that can't vent or dry itself holds on to every leak. Census figures put the typical Bellevue home's build year at 1982, and many from that era have crawl spaces, bathroom fans that vent into the attic rather than outdoors, or single-pane windows that sweat all winter.

Where We Find It

Below grade

Basements that took on water during a storm, especially where carpet and pad stayed wet for days. Lower walls behind finished drywall are the usual hiding place.

Attics and bathrooms

Roof leaks that drip quietly onto insulation, and bathrooms where steam has nowhere to go.

Condos and shared walls

Roughly four in ten Bellevue housing units are in buildings of five or more units. A slow leak from the unit above can feed growth in a ceiling cavity long before a stain appears.

Our Remediation Steps

1. Assess. Moisture readings and a visual inspection tell us how far the problem reaches. We don't guess at hidden areas; we open them if the readings point there.
2. Contain. Plastic sheeting and negative air pressure keep spores from spreading to clean rooms while we work.
3. Remove. Porous materials with growth, such as drywall, insulation and carpet pad, are cut out and bagged. Solid wood framing is cleaned and treated.
4. Dry. Dehumidifiers bring the affected area down to normal moisture levels before anything is closed up.
5. Rebuild. New drywall, paint and trim once readings confirm the space is dry.

Keeping It From Coming Back

Run bathroom fans that vent outside, keep gutters and downspouts clear, and check under sinks a couple of times each winter. If the growth came from a flooded basement, our basement flooding cleanup page explains how to cut the risk of a repeat.
