Mold & Mildew Cleanup in Maple Valley, WA

Calling for help

The phone number on this page links you with an independent remediation company that serves Maple Valley. No one from this site comes to your house; the company you're connected with does the visit and the work. It helps to have a rough idea of how many square feet are affected, which rooms, and what seems to be causing it, whether that's a shower, a window, a damp lower room or water collecting outside. Expect the company to measure moisture in the material behind the growth, not just look at the spots, and to write up what it plans to clean, remove and leave for you to repair.

What changes the bid

Angi's Seattle cost guide lists bathroom mold remediation at $425 to $825, with most pros charging $10 to $25 a square foot. Factors in a Maple Valley bid:

• size of the area and how many rooms are involved
• cleanable surfaces versus drywall or carpet that has to be cut out
• whether outside drainage is pushing water toward the house
• containment needed to keep dust out of lived-in rooms
• repainting and patching after the work

Maple Valley conditions

Maple Valley is a southeast King County suburb about 22 miles from Seattle, incorporated in 1997 and centered on SR 169 and the Four Corners district. Lake Wilderness, Lake Lucerne, Rock Creek and part of Pipe Lake are inside city limits, and the Cedar River runs just past the northeastern edge. The median home was built in 2002, so many houses are fairly new and well sealed, which keeps heat in but also holds moisture from showers, cooking and laundry unless fans run regularly. Through the long gray season, that shows up as condensation on windows and mildew on bathroom ceilings and closet walls.

A few neighborhoods have an outdoor water problem too. The city says Cedar Downs and Cedar Downs Village in the northwest part of town have long-standing localized flooding from drainage problems, including filled or modified ditches and poorly maintained stormwater facilities. Repeated pooling near a foundation can keep lower walls damp. Permit questions go to Economic and Community Development.

Prep before the visit

• Photograph growth and any water stains.
• Note when the smell or spots are worst.
• Clear furniture and stored items away from the wall.
• Check that gutters and downspouts carry water away from the house.
• Have any past leak or repair records on hand.
