Randolph's plumbing year follows the weather. If a pipe freezes, a basement floods or a water heater quits, call (617) 752-0573. That is our 24/7 dispatch line for emergency plumbing in Randolph, MA, and it answers around the clock. Randolph borders Braintree to our west-southwest, so we are a short drive away from your door.
Randolph was incorporated in 1793 from Braintree's fourth precinct, and the two towns still draw on the Great Pond system for water. This page is organized by season, because that is how most Randolph plumbing trouble shows up. Below we cover what fails in each season, what you can do yourself and when to call.

Winter in Randolph: frozen pipes and the 48 inch frost line
The nearest NOAA station we read is the Blue Hill Observatory area in Milton, and its 1991 to 2020 normals count about 121 days a year with lows at or below freezing. January alone averages 27.5 such days. Randolph is not measured there, so treat those as indicative. The takeaway is that pipes in exterior walls, unheated garages and crawlspaces face a long freezing season.
The Massachusetts residential code sets a frost line depth of 48 inches, and the plumbing code requires protection for exposed pipes that could freeze. If a faucet slows to a trickle on a very cold morning, the line is probably frozen but not yet burst. Open the faucet, warm the wall with a hair dryer on low and never use an open flame. If a pipe has already split, you need burst pipe repair right away.
Pipe frozen or split in Randolph?
Close the main, open the lowest faucet and call (617) 752-0573. Our dispatch line answers around the clock.
A pipe has burst in the cold: do this now
Water damage grows by the minute. These actions limit it before we arrive.
- Close the main shutoff where the water line enters the house.
- Open the lowest faucet to drain the pipes.
- Turn off power to any wet area at the breaker if you can reach it dry.
- Call (617) 752-0573, the 24/7 line, and tell us where the split is.
Spring thaw and heavy rain
The Blue Hill normals show about 53.9 inches of precipitation and 69.7 inches of snowfall in an average year. When that snow melts onto saturated ground, basements with a weak sump pump are the first to show it. For you, that means testing the pump in March, not in the middle of a storm.
Pour water into the pit until the float rises and confirm the pump starts and clears the water. A discharge line must carry water outdoors and away from the foundation. If the pump is old, short-cycling or silent, a sump pump replacement with a battery backup is the more dependable choice.
Summer: hose bibs, irrigation and the water bill
Summer rarely brings emergencies, but it brings quiet leaks. A hose bib that drips behind a shrub, an irrigation valve stuck open or a toilet that runs all night can all send the water bill higher. A simple test is to shut off every fixture and watch the meter. If it still turns, water is going somewhere.
That is when a leak detection visit helps. Pressure tests and listening equipment find a leak without opening every wall. We would rather locate a buried line precisely than dig a trench on a guess.
Fall: water heaters and the first cold snap
October is when old water heaters announce themselves. A rumbling tank, rust-colored hot water or moisture at the base all point to a unit near the end. Replacing a tank by choice in October beats an emergency swap in January, and we can often book it as a planned visit.
Under state rule 248 CMR 3.05, replacing a water heater needs a permit, and permits go to licensed individuals. Randolph's Inspectional Services is at Town Hall, 41 South Main Street, second floor, with the main line at 781-961-0921. The town lists the plumbing inspector's phone as 781-961-0920 for Monday, Wednesday and Thursday, and asks that you call before 9 am. We handle that contact for water heater replacement jobs.
Randolph through the year: what fails and what to do first
Use this table to match the season to the likely cause.
| Season | What tends to fail | First move. |
|---|---|---|
| Winter. | Pipes in exterior walls, garages, crawlspaces, hose bibs. | Open the faucet, warm the wall gently, shut the main if a pipe splits. |
| Spring. | Sump pumps, floor drains, basement walls. | Test the pump, clear the discharge line, check the battery. |
| Summer. | Dripping bibs, running toilets, irrigation valves. | Do the meter test, then call for leak location. |
| Fall. | Aging tanks, boiler piping, exterior shutoffs. | Look at the tank base, plan the replacement, drain outdoor lines. |
What to do before the plumber gets to Randolph
Four steps limit damage in any season.
Close the main valve.
Find the shutoff where the line enters the house, usually in the basement. Turn it clockwise until it stops.
Turn off power near water.
Use the breaker panel to cut power to wet rooms. If the panel is in a wet basement, call the electric utility instead of wading in.
Protect what you can.
Move belongings off the floor, and photograph damage for your insurer. Place buckets under active drips.
Call the 24/7 line.
Call (617) 752-0573, tell us the address, and describe the problem. We book the earliest same-day appointment available.
Randolph's water: the shared Great Pond system
Randolph is served by the Randolph-Holbrook Joint Water System. Water is produced at the Great Pond Water Treatment Plant in Randolph from Lower Great Pond, Upper Great Pond, Richardi Reservoir and the Farm River. Braintree's own report describes the same Great Pond reservoir system as its main source, so the three towns share a water origin.
Holbrook's 2025 report lists hardness for the shared system at 56 mg/L from a single sample, which is about 3.3 grains per gallon by simple arithmetic. Braintree's 2024 report prints 47.8 mg/L. Water in this range is on the soft side, so mineral scale builds slowly in a water heater, and age and anode condition matter more than a softener.
Holbrook's report also says a new treatment plant is scheduled to go into service in 2026. If your water looks cloudy or rust-colored after a change, run the cold tap for a few minutes, and if it persists, call Randolph's water division at 781-961-0942.
Crawford Square, West Village, Tower Hill and the housing mix
The town's 2013 Preservation Plan names Crawford Square as the commercial and institutional center, with early residential concentrations in West Village and Tower Hill. Stetson Hall, built in 1842, is a landmark of that older core. Buildings in those older areas may hold older drains and original shutoff valves, so tell us before we cut into a wall.
Census survey estimates put Randolph's median year built at 1966. About 14 percent of units date from 1939 or earlier, 23 percent from 1940 to 1959, and 32 percent from 1960 to 1979. About 71 percent are owner-occupied and 73 percent are single-unit. Homes from the 1960s and 1970s are now 50 to 60 years old, which is old enough for original supply stops and fill valves to seize.
We also serve the neighbors on either side. See how we handle Holbrook, which buys its water from the same system, and Quincy. For a recurring slow drain anywhere in Randolph, drain cleaning with a camera look is the first step.

If you are unsure whether an address is in Randolph, tell us the street and we confirm.
Holbrook's 2025 report lists 56 mg/L for the shared Great Pond system from one sample, about 3.3 grains per gallon. That is on the soft side. Check the current report or ask the water division for the figure that applies to your tap.
Open the faucet, warm the wall or pipe gently with a hair dryer on low, and never use an open flame. Keep the faucet slightly open once water flows. If you see a split or water appears, close the main and call the 24/7 line.

Holbrook buys all of its water from the Randolph-Holbrook Joint Water System, which is produced in Randolph. Both towns therefore receive water from the same plant.
