Emergency Plumber Boston: $108 to $542 + Frozen Pipe Steps

Published Boston prices from Angi's August 2026 emergency plumber guide. Parts, permits and water cleanup are extra.

Do this now: before the emergency plumber arrives

1. Smell gas? Get everyone out and call 911 or the gas utility from outside. Do not try to find the leak.
2. Close the main water shutoff. For one fixture, close the valve under the sink or behind the toilet.
3. Keep away from water near outlets; shut the breaker off only from a dry spot.
4. Frozen pipe: BWSC says to thaw it with a hair dryer and never use an open flame.
5. Open a faucet to drain what is left in the lines after a break.
6. Photograph the damage before you clean up, then call your insurer.

Is it an emergency? What can and cannot wait in Boston

A plumbing problem is an emergency in Boston when water is spreading and you cannot stop it at a valve, when sewage is coming up, when a gas line is involved, or when a frozen pipe has split. Those calls justify Angi's after-hours rates of $100 to $650 an hour. A slow drain, a running toilet or one cold faucet can wait for business hours, when Angi's regular Boston rate is $40 to $220 an hour.

Winter is when most of these calls happen. Logan Airport averages 91.6 days a year at or below 32 F, NOAA's 1991 to 2020 normals show, and Angi's Boston guide says winter emergency rates run about 1.5 to 2 times standard prices, with snow, ice and limited parking adding to fees. BWSC says to let a slow trickle run from faucets on pipes in unheated spaces when a cold snap is coming. More in frozen pipes and burst pipe repair.

24 hour plumber in Boston: what nights and weekends cost

A 24 hour plumber in Boston bills by when you call: Angi lists $100 to $320 an hour on evenings, $130 to $430 on weekends and $130 to $650 on holidays, and says a holiday call may cost three times the normal rate. Some companies take emergency calls around the clock; hours vary, so ask the after-hours rate and the trip fee before anyone is sent. If the water is off and nothing is spreading, booking the next morning saves the premium.

Your pipe or BWSC's? The LUTO 15-day rule

A leak on the private part of your water service pipe is the owner's to fix under BWSC's Leak Up To Owner program, and the owner has 15 days to repair it or service is terminated, immediately in an emergency. For eligible one to three family homes with a pipe 2 inches or smaller, BWSC can replace the pipe and spread the cost over 24 equal installments on the water bill. Contractors working on the service need BWSC permits. BWSC Operations: 617-989-7900.

The sewer lateral is also yours, from the building to the BWSC main. If a backup turns out to be a collapsed or root-blocked lateral, BWSC's Sewer Lateral Financial Assistance Program can give a one-time grant of up to $8,000 or $6,000 after BWSC verifies it, with three estimates from BWSC-licensed and bonded contractors.

Old Boston houses and emergency plumbing

The median Boston home was built in 1947, the Census Bureau's 2020 to 2024 survey shows, against 1980 nationally. Angi's Boston guide says Federal-era brownstones and pre-war triple-deckers often need labor-intensive work, and that neighborhoods like Beacon Hill and the North End have aging plumbing and tight access, which adds labor time. Expect an emergency in an older building to take longer than the same job in a newer house.

Who can do emergency plumbing work in Massachusetts

Massachusetts requires a licensed plumber for residential plumbing work, and apprentices must work under direct supervision, Angi's Boston guide notes. The Board of State Examiners of Plumbers and Gas Fitters licenses journeymen and masters (617-701-8798); look up the plumber on the state's eLIPSE search. Even at 2 a.m., ask for the license number and a written price.

Seniors on fixed incomes can ask the City about Minor Home Repairs for Seniors, which covers plumbing repairs up to $2,000 for owners 62 and older at or below 80% of area median income. It is not an emergency service, but it can pay for the follow-up repair.
