Sewage Backup Cleanup in Lexington, MA
Sewage that rises through a floor drain or toilet is never simply dried. The crew seals off the area, hauls out whatever the water reached, disinfects each surface and then dries the structure to a reading.

How sewage backup cleanup is handled in Lexington

Remove and extract
Sewage is pumped out and porous materials it touched are bagged.

What does sewage backup cleanup cost in Lexington, MA?

Why sewage is not dried in place
Sewage carries bacteria, viruses and parasites, so anything porous that it touched cannot be made safe by drying. Carpet, pad, insulation and wallboard are removed and bagged. Hard surfaces and framing are scrubbed and treated, then dried.
- Plastic barriers seal off the work zone.
- Air scrubbers with HEPA filters run during removal.
- Crew members wear protective suits, gloves and respirators.
Sewage that sat for a day behaves differently from sewage that was cleaned up quickly. Bacteria multiply, odors soak into carpet and wood, and the list of items that must be thrown out grows.
Where the problem sits
A backup can start in the public sewer or in the pipe running from the house to it. Who owns that pipe has to be confirmed, so check with the Town's Water and Sewer Division and a plumber. The crew handles the contamination either way, then moves to structural drying.
Where the water goes next
The pipes beneath Lexington streets feed pump stations, including the main station at Route 128 and Bedford Street, and from there the sewage travels on to the MWRA. A blockage downstream of a house can push water back through the lowest drain.

Sewage Backup Cleanup questions in Lexington, MA
How do I know if the Town has a sewer overflow?
The Lexington Water/Sewer District sends a public advisory when a sewer discharge or overflow occurs, and residents can sign up for alerts through CodeRED.
Who is responsible for the pipe that backed up?
That can depend on where the blockage sits. The Town's Water and Sewer Division and a plumber can say whether the problem is in the street or on the property.
Can I clean up a small sewage backup myself?
No. Even a small amount is Category 3. Protective gear, proper disinfectant and removal of porous items are needed to keep the house safe.
What gets thrown away after sewage?
Carpet, pad, insulation, soaked drywall and soft belongings it touched. Hard items can be cleaned and treated instead.
Will insurance cover sewage damage?
Many policies exclude sewer backup unless an endorsement was added. Your own policy decides, so ask your insurer.
How long until the house is safe?
A typical job lasts roughly a week. A last clean and passing readings decide when the barriers come down, and the air scrubbers leave last.
