When a plumbing problem cannot wait
An emergency plumber in Derry earns the name when water is moving where it should not, sewage is coming back up a drain, or the house has lost heat or hot water in a cold week. Those jobs do not wait for business hours, and our line is open 24/7 for exactly that reason.
While you wait for the plumber, shut off the water at the main valve and keep everyone away from wet electrical outlets. Then call and tell the dispatcher what you can see. A clear description lets the right tools ride in the truck the first time.
- Water running from a burst or split pipe: close the main shutoff, then call.
- Sewage backing up in a tub, floor drain or basement: stop using every drain and call.
- No hot water, or a water heater leaking at the base: switch off the heater and call.
- A sump pump that stopped while the basement is taking on water: call right away.
- A toilet that overflows and will not stop: close the valve behind it, then call.
What happens when you call
The call is short on purpose, because a person with water on the floor needs action more than a script.
- A dispatcher picks up. You describe the problem, give the address and say whether water is still running.
- You get safe next steps. That usually means which valve to close and which room to stay out of.
- A plumber is assigned. You hear what the dispatcher can promise about timing, and we never guarantee an arrival window that traffic or weather could break.
- The price comes before the work. The plumber diagnoses the problem, explains the repair options and gives you a clear price, and nothing starts until you agree.
Plumbing in Derry homes: what the town's history means for your pipes
Derry was settled in 1719 and incorporated as its own town in 1827. The state's community profile counts 13,776 housing units in Derry (American Community Survey, 2014 to 2018), from farmhouses near the villages of Derry and East Derry to homes built in later decades. That mix matters, because an older house can still carry galvanized steel supply lines that corrode from the inside and lose pressure over time.
The Derry Water Department publishes a lead service line inventory that shows how many lines it could classify. Of 4,466 service lines, none were classified as lead, 20 were galvanized lines requiring replacement, and 2,144 were still marked unknown. If your line is unknown, the town offers a free lead test, and its water office is at 603-432-6147.
Knowing what runs from the curb stop into your cellar helps you decide whether a repipe quote is worth getting. See our page on water service line repair for the part of the pipe that belongs to you.
Many homes in Hampstead, Chester and parts of Windham and Londonderry rely on private wells and septic systems instead of town water and sewer. Those homes add well pressure tanks and septic-related drain problems to the usual list. We cover the house plumbing side of a well system and will tell you honestly when a job belongs to a well driller or septic contractor instead.
Before the plumber arrives: a short checklist
These steps limit damage and give the plumber a head start. None of them needs tools beyond a flashlight.
- Find the main water shutoff, usually where the line enters the cellar or utility room, and turn it fully clockwise.
- Open the lowest faucet in the house to drain the lines and take pressure off a leak.
- Switch off the water heater breaker or gas control if the tank is leaking or the lines are open.
- Move rugs, boxes and electronics out of the wet area, and photograph the damage for your insurer.
- Keep a bucket under active drips and note which fixtures still work.
- Open the door, put pets away and clear a path to the cellar or crawlspace.
If you smell gas, leave the building and call 911 or the gas utility before you call a plumber.
What changes the price of an emergency plumbing job in Derry
We do not print fixed prices on this site, because the same symptom can have very different causes. These are the factors the plumber weighs, so the number you hear on the phone makes sense.
| Factor | Why it moves the price |
|---|---|
| Access | A pipe in an open cellar ceiling is a shorter job than one behind plaster or under a slab. |
| Pipe material | Copper, PEX, galvanized steel and cast iron each need different fittings and labor. |
| Parts on hand | A common valve is a same-visit fix, while an uncommon water heater model may need a second trip. |
| Time of day | Night and holiday calls cost more to staff, and the dispatcher can explain how that applies to your call. |
| Scope found on site | A camera or pressure test sometimes shows a bigger problem than the first symptom, and the plumber explains it before continuing. |
Insurance note: many homeowner policies cover sudden pipe bursts but not slow leaks or wear. Ask your insurer before you rely on coverage.
How to check any plumber's license in New Hampshire
New Hampshire licenses master and journeyman plumbers through the Mechanical Licensing Board, which sits under the Office of Professional Licensure and Certification. Practicing plumbing without a valid license is addressed in RSA 153:37. Before any plumber opens a wall in your house, ask for their license information and verify it through the state licensing office.
Whoever comes to your door, you can ask to see license information, and a good plumber will not mind.

Yes. The line is open 24 hours a day, seven days a week, including holidays. At 2 a.m. the dispatcher still asks what is happening, tells you which valve to close and starts arranging a plumber. Call (603) 815-9179 and describe the problem.
The dispatcher gives you a realistic window when you call, based on where you are and how many calls are open. We do not guarantee an arrival time, because storms and traffic on NH 28 or NH 102 can change it. Same-day appointments are available when the schedule allows.
Treat it as an emergency when water cannot be stopped, sewage is backing up, the house has no heat or hot water in cold weather, or a sump pump has failed during heavy rain. A slow drip or a running toilet can usually wait for a scheduled visit, though you should still close the fixture valve.
We also serve Londonderry, Windham, Hampstead, Chester and Salem from Derry. Each has its own page on this site with local notes. Homes in Hudson, Raymond and Atkinson are close to our coverage edge, so ask the dispatcher about them.
New Hampshire issues master and journeyman plumber licenses through the Mechanical Licensing Board, and you can verify a license through the state before work starts. Ask any plumber for license information before work begins.
Yes. The plumber diagnoses the problem, explains the repair options and gives you a clear price before work starts. If the scope changes after a wall is opened, the plumber stops and explains it first.
We repair the plumbing inside a house on a well, including leaks, fixtures, water heaters and drains. Well pump replacement, well drilling and septic tank pumping are separate trades. If your problem points to one of them, the plumber will say so plainly.
Close the main water shutoff, open a low faucet to drain the lines, switch off the water heater and keep people away from wet outlets. Then call us. The checklist on this page walks through the same steps.
