Sewer line cleaning clears the large pipe that carries all the wastewater from your house out to the municipal sewer. When it blocks, water rises in the lowest drains first, often a basement shower, floor drain or tub. Our 24/7 emergency dispatch serves Milton, MA, so a backup at 2 a.m. still gets an answer. Until the plumber arrives, stop all water use and keep everyone out of standing wastewater.
Questions people ask before calling about a sewer backup
Several fixtures act up together. A toilet gurgles when you drain the tub, a basement floor drain bubbles, or wastewater appears in the lowest tub or shower. A single slow sink points to its own branch instead, which is a drain cleaning job.
Look in the basement near the foundation wall where the main pipe leaves the house, in a crawl space, or outside in a short pipe with a threaded cap near the foundation. Many older homes have none. Without a cleanout, the plumber may have to reach the line through a toilet or roof vent.
That depends on where the blockage sits. Pipe inside your property is normally yours. The section under the street belongs to the municipal system. Call Milton Water and Sewer Division at 617-696-5731 to ask which section is whose, and tell your plumber what they say.
It does if the cause was buildup, such as grease or wipes. If tree roots or a sagging section keep catching waste, cleaning only buys time. A camera look after the cleaning shows which case you have, and sewer line repair may be the lasting answer.
Wait until the plumber has flowed water through the line and confirms it drains at full speed. Then use water gradually, not all at once. If the line backs up again within days, call right away since that points to a partial blockage or damage.
Yes. Emergency dispatch runs 24/7, including weekends and holidays. A sewage backup does not wait for business hours, and we do not treat it that way. Same-day appointments are also offered when available for lines that are slow but not yet overflowing.
Call the number on this page and tell the dispatcher which unit and floor are affected. Ask the tenant to stop all water use in the building. Keep photos and the plumber's report, since they may matter for the lease or your insurer.

(617) 752-0573Who maintains which part of the sewer
A house sewer has two parts. The private pipe runs from the building to the property line or the street connection. The public main runs under the street. Where one ends and the other begins differs from address to address, so do not guess.
Ask Milton Water and Sewer which section is whose before you pay for work. If the stoppage is in the public main, the Town handles it. If it is on your side, a licensed plumber clears it.
Which problem do you have? Branch, main or street
| What you see | Likely location | Who clears it |
|---|---|---|
| One sink or tub drains slowly | Branch line to that fixture | Plumber, drain cleaning |
| Toilet gurgles when another fixture drains | House main or stack | Plumber, main line cleaning |
| Basement floor drain bubbles or overflows | House main or lateral | Plumber, main line cleaning |
| Neighbors report the same backup | Public main under the street | Town, after you call Milton Water and Sewer |
| Backup only during heavy rain or high tide | Surcharged public sewer or inflow | Town and plumber, depending on the cause |
A plumber can usually tell which case you have after a quick check of the cleanout and a camera look.
Storm surge and sewer backups in East Milton
The Town of Milton Community Resilience Building Workshop summary from April 2020 described storm surge in East Milton backing sewers up into homes. It also named the Neponset River banks, Turner's Pond, Pine Tree Brook and Unquity Brook as areas with flooding.
If your backup arrives with a storm or a very high tide, cleaning your own line may not stop it, because the public sewer itself can be overloaded. In that case, call a plumber to confirm your side is clear, call Milton Water and Sewer to report it, and ask a plumber about a backwater valve on the house drain. Do not run the washing machine until the water level outside drops.

Licensed plumbers are dispatched day and night, and you hear the price before work starts.
How the plumber clears a main sewer line
Locate the access
The plumber finds the cleanout, or removes a toilet if there is none, to get a cable or hose into the main.Run a drum machine
A heavy cable with a cutting head breaks up roots, paper and grease along the way.Follow with water
A jet or a hose flush carries cuttings out so they do not form a new plug a few feet away. Hydro jetting is used when buildup lines the wall.Flow test
Water runs through the house drains to confirm everything empties at full speed.Offer a camera look
If the line was badly blocked or has clogged before, the camera shows why.
When sewage is coming up in the house
Wastewater inside the house is a health hazard and a same-night problem. Call at any hour and we dispatch through the night and on weekends. While waiting, these actions are safe:
- Stop all water use. That means no flushing, no laundry and no dishwasher.
- Keep kids and pets away. Raw sewage carries bacteria, so wash hands well after any contact.
- Wear rubber boots and gloves if you must enter, and never touch electrical items in wet areas.
- Open windows for ventilation in the affected room.
- Photograph the damage for your insurer before you clean up, then move belongings to dry spots.
What affects the price of sewer line cleaning
Cleaning a main line can range from a short job to a long one with root cutting and a follow-up flush. You get a clear price before work starts. The drivers are:
Access
An outside cleanout makes the work faster than removing a toilet.
Blockage type
Paper and grease clear faster than thick roots, which need cutting heads and extra passes.
Line length and pipe size
Longer runs to the street need more cable and more time.
Camera look
A recording adds time but reveals damage that changes the plan.
Standard homeowners policies often cover sudden and accidental water damage but usually not wear, gradual leaks or maintenance, and many exclude sewer backup unless an endorsement was added. Policy wording decides, so read it or ask the insurer.
Keeping the sewer line clear afterward
Do not flush wipes, even those labeled flushable. Keep grease out of kitchen drains, and scrape plates before washing. If you have large trees near the line, ask a plumber to camera the pipe every so often. We also serve Randolph and other towns around Milton with the same emergency line.
