Canton · Emergency Plumbing
Frozen line, split pipe, or sewage at a floor drain in Canton? Make the house safe, shut the water off, then call to reach an independent plumber who takes Canton jobs.
Canton, Massachusetts
Winter is when Canton's worst plumbing nights tend to happen. Norfolk County was declared a federal disaster area for the January 2015 blizzard, and on February 12 of that year the town's Building Department posted a public warning that roofs could collapse under the snow. Storms like that bring frozen supply lines, pipes that split when they thaw, and power cuts that stop sump pumps, often all in the same week.
Not every emergency starts inside your walls. Canton runs its own water system, with 128 miles of main and about 7,300 service connections, and its Water and Sewer Division keeps an emergency line for problems on the town's side. If the street is flooding or the whole block is dry, the town needs to hear about it first.
When the trouble is in your house, call or send a request and you'll be connected with an independent local plumber who serves Canton. South Shore Plumber Finder is a referral service; we don't do plumbing work ourselves.
If one faucet or the whole house goes dry during a cold spell while neighbors still have water, a pipe has probably frozen. It can split as it thaws, so shut the main before warming it.
Water coming out of a light fixture means it has reached wiring. Stay out from under it and shut off power to that area only if you can reach the panel from somewhere dry.
Wastewater at a floor drain or basement toilet means a blockage in your house line or the town sewer. Stop running water in the house and keep people and pets away from it.
Water surfacing in the street or at the curb is usually the town's main or a service connection. Report it to Canton's Water and Sewer Division.

Winter Storm History
Norfolk County, which includes Canton, was part of federal disaster declarations for winter storms in January 2015, March 2018, and January 2022. Long cold snaps and power outages are when exposed pipes in garages, crawl spaces, and outside walls freeze, so know where your main valve is before the next one.

Town Water System
The division runs 128 miles of water main, five storage tanks, and two treatment plants, and lists a separate emergency number on its page. A break in the road or a backed-up town sewer main is the town's to handle, while the plumbing inside your home is yours.
Gas Utility
If a burst pipe floods the area around a gas water heater or boiler, or you smell gas at any point, Eversource Gas is the company to call, from outside the house. Leave gas valves on appliances for the plumber or the utility.

Work through these in order, starting with safety.
If you smell gas, get everyone out and call 911 or Eversource Gas once you're outside. Keep away from standing water near outlets, the panel, or appliances, and treat any sewage as a health hazard.
The main valve is typically in the basement, close to the water meter where the service line enters through the foundation. Turn it clockwise until it stops, then open a low faucet to drain what's left in the pipes.
Check with a neighbor or look at the street. A shared outage or water in the road goes to the town's Water and Sewer Division; a leak inside your home goes to a plumber.
Take photos and short videos of the leak, the wet areas, and anything that was damaged before you start drying things out. Your insurer will likely ask for them.
What to expect
The plumber's first job is to stop the water and find where it's coming from. With a frozen pipe, that means warming the line slowly, finding the split, and cutting in a new section. With a sewer backup, they'll usually run a cable or camera through the cleanout to see whether the blockage is in your line or past it.
Night-time fixes can still need a plumbing permit afterward. In Canton, plumbing and gas permits go through the Gas and Plumbing Inspector at the Building Department in Memorial Hall, and the department's staff book the inspection. Ask the plumber whether the repair needs a permit and who will file it.
If a storm has knocked out power or water has reached the panel or gas appliances, the plumber may hold off on restarting equipment until the electrician or Eversource has checked it. A good first visit often ends with the water off, the house safe, and a written plan for the permanent repair.
Hire smart
Plumbing and gas fitting in Massachusetts require a license from the Board of State Examiners of Plumbers and Gas Fitters, and most plumbing work needs a permit from the town's plumbing inspector.
Ask for the plumber's Massachusetts license number and look it up on the state's occupational license search. It takes a minute and protects you if something goes wrong.
Find out before work starts whether there's a trip charge, an hourly rate, or a flat price, and whether nights and weekends cost more.
If the night's repair is temporary, ask for the permanent work to be priced in writing so you can compare and decide when things are calm.
Ask for an invoice that names the cause of the failure and what was replaced, and keep it with your photos for the insurance claim.
Costs
The hour you call, how much water got loose, and how hard the failed pipe is to reach drive most emergency bills. A split line behind a finished basement wall or under a bathroom floor takes longer than one hanging in an open basement ceiling, and a sewer backup that needs a camera adds equipment time.
First rule out the town's side, since a main break in the street shouldn't land on your invoice. Once a plumber is there, ask how the visit is billed, get the permanent repair estimated in writing, and ask whether the permit fee is included.

Close the main valve first so a split pipe can't flood the house when it thaws. Open the faucet on that line and warm the area gently with a hair dryer or space heater kept away from anything flammable; never use an open flame. If you can't find the frozen spot or a pipe has already split, call a plumber.
Call the town's Water and Sewer Division, which lists an emergency number on the town website. Breaks in the street and town mains are the town's to repair, not your plumber's.
When you call, you'll be connected with an independent plumber who serves Canton, and when they can come depends on their schedule. Shut off the water and make the house safe while you wait.
Many pipe repairs do, even when they're done in a hurry. Plumbing permits in Canton go through the Building Department's Gas and Plumbing Inspector, and a plumber with a Massachusetts license should file it.
Stay out of the water if it's near outlets, the panel, or gas appliances, and call 911 or Eversource from outside if you smell gas. Once it's safe, a plumber can check the sump pump, the water heater, and the drains.
