Raw Sewage Cleanup: Questions from Waltham, MA Property Owners
Can I clean sewage myself?
A very small spill on a hard floor can be handled with gloves, boots, eye protection and a disinfectant used by label directions. Anything that reached carpet, drywall or a large area needs professional cleanup, because hidden contamination is hard to see.
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.
How much does a sewer backup cleanup cost?
The price depends on how much sewage there is, how far it spread and which materials must be removed. A bathroom overflow costs less than a flooded basement. The team sets the price after seeing the space, and nothing is decided on a call alone.
How do I know if sewage is leaking under my house?
Common signs include a sewer smell in the yard or crawl space, soft or damp ground near the foundation, gurgling drains and slow drains in several fixtures at once. A plumber can confirm the leak. Once it is found, a cleanup team can take care of the contaminated soil, materials and odor.
What are the signs of a sewage leak?
Watch for a rotten-egg or sewer smell, wet spots or stains on floors and walls, unusually green grass over a pipe, and multiple drains backing up at the same time. If any of these show up, keep people away from the area and have the cause checked.
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.
