Sewer Backup Questions Answered for Watertown, MA

How long does sewage cleanup take?

Small jobs may be finished in a day, while larger ones with tear-out, drying and odor treatment take longer. The time depends on the area affected and what had to be removed. The crew can tell you what to expect after assessing the space.

How do I disinfect a basement after a sewer backup?

After the sewage and soaked materials are out, floors and walls are scrubbed with a cleaner, then treated with an EPA-registered disinfectant used by label directions. Unsealed concrete can hold odor and needs extra attention. Crews often handle this step with professional equipment.

Who pays for sewage cleanup, the landlord or the tenant?

It depends on the cause, the lease and local law. A landlord's policy may cover the building, while a renter's policy may cover belongings. If the blockage was in a public sewer main, the city or utility may be responsible for the repair.

Do plumbers clean up sewage?

Plumbers usually clear the blockage or repair the pipe, but most do not remove contaminated materials or disinfect the space. A sewage cleanup company picks up where the plumber stops, and the two jobs often happen in sequence.

Is a sewage backup a biohazard?

Yes. Raw sewage is Category 3 contamination and can carry bacteria, viruses and parasites. That is why cleanup crews wear protective gear and remove porous materials instead of just drying them.

How do I clean sewage off concrete?

Concrete is porous, so sewage soaks in. The surface is scrubbed, rinsed and treated with a disinfectant, and the wash water is collected rather than spread. Stubborn odor may need a second round of treatment.
