Emergency Plumber in Boston: 24 Hour Costs, Shutoffs and Who to Call

What emergency repairs cost in Boston

The figures start from national emergency rates and apply the Boston metro construction cost factor of 1.23 from the U.S. Army Corps of Engineers. The table shows prices for your part of the metro.

Estimates for 2026, including labor and standard parts. Boston prices use the metro's construction cost factor of 1.23 (US average = 1.00) from the U.S. Army Corps of Engineers Area Cost Factors. Your quote depends on access, materials and the condition of the home.

How the time of the call changes the rate

Emergency rates climb with the hour. A same-day call during business hours is the cheapest. Weeknights after closing cost more, weekends cost more again, and holidays cost the most.

Pay for a night call when water is still running, sewage is coming up, or gas is in the air. A dripping trap or a slow tub drain can wait for Monday. If you can stop the water at a valve and nothing is getting worse, a daytime visit usually costs less.

What common emergencies cost to fix in Boston

Pipes inside walls, under a slab or under the yard cost the most, because they take the longest to reach. Cleanup, plaster and flooring repairs are billed separately. For everyday plumbing prices, Boston's older pipe materials and city permit fees, see our Boston plumbing guide.

The first hour: what to do before help arrives

Water coming through a ceiling or wall

Close the main water valve. It usually sits where the supply line enters the house, often in the basement near the street side. Then shut off breakers for any room where water is reaching outlets, light fixtures or appliances. Open a faucet on the lowest floor to drain what is left in the pipes. Photograph everything before you start mopping.

In most Massachusetts communities the property owner owns the water service line all the way to the main, so a break under the street is still your bill. The water department typically owns and operates the curb stop, but the pipe on both sides of it belongs to you, according to Aroso Plumbing. Older properties may still have galvanized steel or a lead service line.

You smell gas, or hear hissing

Don't light anything and don't flip any switch, on or off. Get everyone out. From a safe spot outside, call 911 if there is fire or anyone is hurt, then call your gas utility. Gas piping work in Massachusetts is licensed through the Board of State Examiners of Plumbers and Gas Fitters, so the repair needs a licensed gas fitter.

Shut the meter only when you smell gas, hear it leaking or see other signs of a leak, and only if you can reach it safely. Once the meter is off, leave it off. The utility has to turn the gas back on and relight the pilots.

The power is out, or something is sparking

Check whether the whole street is dark. Report power outages directly to Eversource at 1-800-592-2000 or through its outage page, according to the Town of Medway. Do not call 911 to report an outage.

If you see wires down, call 911 and do not approach them. Inside the house, a hot panel, a burning smell or smoke from an outlet means you should shut off the main breaker if you can do it without touching water, then leave and call 911.

Who to call in Boston

Which trade handles which emergency

Calling the right trade first avoids paying two service fees.

Massachusetts licenses journeyman and master plumbers and gas fitters through the Board of State Examiners of Plumbers and Gas Fitters, and electricians through the Board of State Examiners of Electricians. Sheet metal work runs through its own board, with a restricted J-2 or M-2 license limited to residential dwellings of three stories or less.

For electrical detail, see our Boston electrical guide. For storm and roof questions, see Boston roofing. If the emergency is a failed water heater, the water heater guide covers repair versus replacement.

Sewer backups: your lateral or the city's main?

When sewage rises through a shower or floor drain, the first question is where the blockage sits. The city owns the public main under the street. The pipe from your house to that main is the lateral, and in most Massachusetts communities it belongs to you, including the portion under the public way.

On housing built between 1890 and 1920, the only access is often a plug on the cast iron house trap in the basement floor, or nothing at all, and the line has to be worked through a pulled toilet. Cast iron and clay laterals commonly last 60 to 100 years, Orangeburg often fails at 30 to 50, and modern PVC should outlast the building.

If a break sits under the street, expect a permit and usually a street opening permit on top of the plumbing permit. Cambridge publishes a brochure on protecting your home from sewer backups with backwater valves.

Boston weather that causes emergency calls

Nor'easters and blizzards

The National Weather Service says nor'easters may occur at any time of year but are most frequent and most violent between September and April. They nearly always bring heavy rain or snow, gale-force winds, rough seas and occasionally coastal flooding, and they typically reach maximum intensity near New England. The I-95 Corridor between Washington and Boston is especially impacted.

That combination drives the winter call list: frozen and burst pipes, ice dams, downed service masts and flooded basements. During an active roof leak, put a bucket under the drip, move belongings out of the way, and switch off the breaker for any light fixture that is getting wet. Call a roofer to tarp or repair it once it is safe to get up there.

Coastal flooding and storm surge

Nor'easters can push water ashore along the North Shore and the South Shore. Flood water from outside is usually not covered by a standard homeowners policy, so photograph the water line on walls and keep every receipt for drying and cleanup.

Heat waves and electrical load

A long July heat wave loads every circuit in an old house at once. Window units, dehumidifiers and fridges cycling together trip breakers and overheat panels. If a breaker will not reset, or the panel feels hot, stop and call an electrician rather than swapping in a bigger fuse.

Do you need a permit for emergency work?

Yes, for anything beyond a minor repair. In Massachusetts the Board of State Examiners of Plumbers and Gas Fitters licenses journeyman and master plumbers and gas fitters, so ask for the license number before work starts. Electricians are licensed by the Board of State Examiners of Electricians.

A plumbing permit is not required for minor repairs such as fixing a leaky faucet, valve or other working part of a fixture, or for clearing a blocked drain. A burst pipe, a gas line repair or a sewer lateral repair does need one.

Each city runs its own permit office:

Boston: Inspectional Services Department, 1010 Massachusetts Ave, (617) 635-5300. Off-hour inspection requests go by email to ISDOffHourInspection@boston.gov.

Cambridge: Inspectional Services, 831 Massachusetts Ave, (617) 349-6100. Electrical and plumbing/gas permits each require at least a rough and a final inspection, and a building inspector cannot approve contractor steps until the utility inspector has signed off.

Somerville, Newton, Quincy, Brookline and the surrounding towns each have their own building department enforcing the same state codes.

Construction hours matter after a storm. Cambridge allows construction in residential areas Monday through Friday 7:00am to 6:00pm and Saturdays 9:00am to 6:00pm, with no Sunday work without a special permit from the Police Department. Its noise ordinance exempts emergency work of public service utilities.

Ask the pro to confirm in writing that they will pull the permit. Permit fees for everyday plumbing work are listed in our Boston plumbing guide.

Insurance: what to record during an emergency

Insurers pay for sudden events far more often than slow ones. Three gaps matter in Boston:

Sewer backup: Many policies cover water damage from a backup only with a specific endorsement, and almost none cover the buried pipe itself. Some municipalities offer optional service line coverage through the water bill.

Flood: Water that flows in from outside during a nor'easter is usually excluded from a standard policy.

Freezing: A pipe that bursts after a freeze is often covered, but a leak from a pipe that corroded over years usually is not.

Before cleanup, take wide photos of each room and close-ups of the damage, the water line on walls and the failed part. Keep the broken part if the plumber removes it. Ask for an invoice that states the cause in plain words, and save every receipt for drying, cleanup and hotel stays. Call your insurer the same day if you can.
