How Main Sewer Line Backup Cleanup Works in Larkspur

1. Extract the sewage

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

2. Map where it traveled

   A moisture meter and a thermal camera show how far the sewage went. The technician marks wet spots on a floor plan and follows the water into walls, under cabinets and across the slab.

3. Cut out what it soaked

   Drywall is cut above the water line, usually a little higher to catch wicking. The crew removes the wet section, bags it and leaves clean framing exposed to dry.

4. Sanitize, dry and check

   Floors, slabs and framing are scrubbed and treated with an EPA-registered disinfectant. Then air movers and LGR dehumidifiers go in, placed by the size of the room and the materials in it.

What to Do Before the Crew Arrives

Time is the one thing a homeowner cannot buy back. Each hour sewage sits, it moves deeper into the subfloor and the framing. A call now means less to remove and less to dry.

• Stop using every toilet, sink, shower and washing machine.
• Call a plumber to check and clear the main line.
• Keep everyone out of rooms with sewage on the floor.
• Do not run a bath or the washer to test whether the pipe is clear.
• Photograph every room that has sewage before anything moves.
