How Septic Overflow in Basement Cleanup Works in Canterbury

1. Extract standing sewage water

   The technician checks whether wastewater moved beyond the visible puddle, then expands extraction as needed.

2. Map contamination and moisture

   Technicians compare suspect materials with dry areas to define the drying scope.

3. Remove and sanitize affected materials

   The crew cleans hard surfaces after extraction and sanitizes the remaining affected area.

4. Dry the structure and verify

   The crew records temperature, humidity and material condition through the dry-out.

What to Do Before the Crew Arrives

Household fans cannot make untreated sewage safe. The technician first removes contamination, then dries the building to reduce ongoing moisture risk.

• Stop using household drains until a septic company checks the system.
• Leave wet electrical and utility equipment untouched.
• Photograph the water level from a dry, safe position.
