Londonderry at a glance for a plumbing call
Londonderry has about 25,826 residents across 42.1 square miles, and it was chartered in 1722. Its villages are Londonderry, North Londonderry and Wilson. Exit 4 of I-93 (NH 102) and Exit 5 (NH 28) bring most traffic into town, so plumbers usually arrive by NH 102 or NH 28 from Derry, about 5 miles away. We dispatch around the clock, and the dispatcher gives you a realistic window when you call.
NH 128 (Mammoth Road) crosses town, and half of Manchester-Boston Airport lies in the northwest corner. Heavy traffic near the airport and Exit 5 can slow a plumber at rush hour, which is one reason we never promise a set arrival time. ZIP 03053 is the code we use for the town.
Emergency plumbing in Londonderry, day or night
Water that cannot be stopped, sewage in a floor drain or a cold house in winter all deserve an immediate call. We answer 24/7, and Londonderry addresses are part of our regular route.
Stop the water at the main valve if you can, then call. If a sump pump has failed and the cellar is taking on water, say so first, because storms tend to produce several of those calls at once.
- Burst or split pipe: close the main shutoff and call.
- Sewage backing up in a tub or floor drain: stop using fixtures and call.
- Water heater leaking or no hot water: switch it off and call.
- Sump pump stopped in a storm: call right away.

Before We Arrive in Londonderry
These steps limit damage while a plumber is on the way. They need nothing more than a flashlight.
- Close the main water shutoff by turning it fully clockwise.
- Open the lowest faucet in the house to drain the lines.
- Switch off the water heater if the tank or lines are leaking.
- Keep people away from wet outlets and the electrical panel.
- Photograph the damage for your insurer, then call.
If you smell gas, leave the building and call 911 or the gas utility before you call a plumber.

Londonderry notes for plumbing decisions
Woodmont Commons, a 600-acre planned unit development, and other newer neighborhoods mean many Londonderry houses have modern PEX or copper supply lines, while homes near the older village centers can have older piping. Ask what your house has before you assume. Knowing the age of your plumbing helps you judge whether a repair or a repiping quote makes sense.
Number Eight Hill rises to 535 feet, and homes on slopes shed water toward lower neighbors. A sump pump with a clear discharge matters most for houses at the bottom of a grade. The sump pump page covers pits, pumps and battery backups.
Some Londonderry streets use town sewer and water, and others rely on private wells and septic systems. Confirm with the town which service your street has, because a septic problem and a sewer problem look alike but need different fixes.
