How City Sewer Backup Cleanup Works in Larkspur

1. Remove wastewater

   Truck-mounted or portable equipment pulls dirty water from the Larkspur floor, depending on access. Portable extraction may be needed where stairs limit access for larger equipment.

2. Map contamination and moisture

   A moisture map includes cabinet bases and thresholds where dirty water can travel sideways. Cabinet bases often create a separate moisture pocket along a wall.

3. Remove affected porous layers

   A wet baseboard may expose damaged drywall paper and the bottom plate behind it. Bottom wallboard sections may need a cut that reaches beyond the visible stain.

4. Sanitize, dry and verify

   Dehumidifiers lower room humidity while air movers dry the remaining clean framing. The dehumidifier lowers vapor while air movement pulls moisture from exposed wood.
