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.
- Keep everyone upstairs and away from the contaminated stairway.

- 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.
Local Conditions That Shape the Drying Plan
Roughly 6% of the local housing stock was built before 1960, but material readings still control cleanup decisions. The typical home in the ZIP codes around Londonderry was built in the 1980s. Subfloor seams can allow wastewater to move beyond the first visible spot. Moisture readings help show whether the floor assembly is affected.
A low drain can overflow in winter as in any season; the crew maps where wastewater traveled.
