Sewage reaches the basement first because it sits lowest in the house. Carpet, pad, drywall, insulation and cardboard soak it up and hold it. The crew treats the whole lower level as contaminated until the work is done.

Sewage on the floor does not wait for the plumber to arrive. Call the cleanup crew first if the plumber is hours away, and shut off water use in the house. Every hour of waiting pushes the sewage deeper into carpet and drywall.

How Basement Sewer Backup Cleanup Works in Mercer Island

1. Extract the sewage

   Speed matters in this step because every hour pushes more sewage into the floor. Crews in Mercer Island pump first and seal off the work area so the spread stops.

2. Map where it traveled

   Photos go with the map. Dated pictures of the source, the water line and the damaged belongings give an insurer a clear starting record.

3. Cut out what it soaked

   Only what is wet or contaminated comes out, and the technician logs every item. That list is the record an adjuster sees later.

4. Sanitize, dry and check

   Daily visits bring a moisture meter and a notebook. Readings are compared with the dry goal, and equipment is moved or added when a number stalls.

What to Do Before the Crew Arrives

Dry-looking drywall can still hold water inside. Growth can start behind a wall where nobody sees it, and it is hard to catch early. A moisture meter and a thermal camera show what the eye misses.

• Stay out of the water and keep children and pets upstairs.
• Do not flush toilets or run water until the plumber clears the stoppage.
• Leave the breaker panel alone if water reaches it, and call an electrician.
• Never mix bleach with other cleaners to treat the floor.
• Photograph the water line and ruined items from the stairs.

The typical home in the ZIP codes around Mercer Island was built in the 1970s. Sewer laterals from these decades have been in the ground for half a century or more. Roots, settling and corrosion have had time to do their work. A camera inspection tells the plumber what is left.

Short freezes slow drains and can harden grease. A drain that was fine in September may be sluggish by December.
