How City Sewer Backup Cleanup Works in Millbrae
-
Remove wastewater
Pumping starts after the blocked drain stops adding new wastewater to the affected room. New inflow must stop before dry equipment can keep pace with moisture.
-
Map contamination and moisture
A technician marks wet wall bases, floor edges and adjacent rooms that the visible pool did not reveal. The map distinguishes a wet tile joint from the porous wallboard beside it.
-
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.
-
Sanitize, dry and verify
A final check documents that the remaining structure is ready for the next work stage. Final measurements document the point when rebuild work can be considered.
