What Sewage in Basement Cleanup Includes in Castro Valley
Finished walls in Castro Valley can hide contamination at the base. Moisture readings show where materials need opening. A stained baseboard may reveal the highest point reached by the overflow before the visible floor dried.
Wastewater on a basement floor can reach carpet pad, wallboard and stored belongings before it looks deep. Sewage is Category 3 water, so contaminated porous materials usually come out rather than being dried in place.
A plumber can explain the source of the backup. The cleanup crew handles the Category 3 water left inside the home. Basement shelving and storage bins may need moving to reveal the full wet perimeter.

Is basement sewage treated as contaminated water?
Yes. Sewage is Category 3 water. The crew uses protective gear and removes affected porous materials before cleaning and sanitizing surfaces that remain.

Photographs from a dry, safe spot can show the water level before extraction. The cleanup crew adds its own images of affected finishes, material removal and drying readings to document the loss.
