Hudson lies south of Londonderry and is reached by I-93 and NH 102. When a sewer backs up or a water heater fails there, the 24/7 emergency line at (603) 815-9179 dispatches a licensed plumber from our Londonderry base to Hudson, NH 03051.
Hudson is a larger town than most of our neighbors, and its Public Works department maintains town sewer and water lines. That makes the first question on every call a simple one. Does the problem sit on your side of the property line or on the town's side?
Who owns the problem: town main or private line
Hudson Public Works, at 2 Constitution Drive, maintains the town's sewer, water and drainage systems. Its number is 603-886-6018. After hours, sewer emergencies are routed through Hudson Police dispatch at 603-886-6011.
Those two numbers are worth saving in your phone. If a backup is happening in the street, in a neighbor's yard or at the town connection, Public Works is the right call. If the backup is inside your house or in the pipe between your house and the main, we clear it and tell you what we find on camera.
| Where the problem shows up | Usually the town | Usually you |
|---|---|---|
| Sewage in the basement floor drain | If neighbors are also backed up | If only your home is affected |
| Wet patch in the front yard | Leak on the street side of the shutoff | Leak on your service line after the meter |
| Gurgling toilets after rain | Overloaded street main | Roots or sag in your sewer lateral |
| No hot water | Never a town issue | Water heater, thermostat or gas supply |
Sewer and drain emergencies in Hudson
A backup that reaches the lowest drain in the house is the most common reason a Hudson caller dials after midnight. We start with a cable to restore flow, then run a camera down the line to see why it stopped. Our sewer line repair page explains the options when the camera shows a cracked or collapsed section.
If roots are the cause, a main that is only cabled will clog again within weeks. Sewer line cleaning with a cutting head or jetting clears the pipe wall, and a follow-up sewer camera inspection shows the result.
Keep one rule in mind while you wait. Do not run the washer, dishwasher or showers, because every gallon goes to the lowest open drain.
Water heaters: old tanks and newer ones fail differently
An older tank and a newer one fail in different ways. A rusted tank leaks at the base and cannot be repaired. A tank with a failed element or thermostat can be, and we diagnose which you have before suggesting a swap.
When the tank has failed, water heater replacement is the honest answer, and we can often schedule it for the same day when stock and schedule allow. If you are replacing before it fails, water heater installation gives you time to compare tank and tankless options.
We quote the price before work starts, and we tell you if a repair is not worth the money.
Reaching Hudson, the 03051 ZIP code and Merrimack
Hudson uses the 03051 ZIP code, and we serve all of it. We reach it from Londonderry by I-93 and NH 102, and the same dispatch line also covers 03053 in Londonderry, 03052 in Litchfield, and 03054 in nearby Merrimack. We name Merrimack here because its calls reach the same dispatcher.
Nearby towns we serve include Litchfield and Derry. Whichever town you are in, you get the same 24/7 line, the same clear price before work starts, and the same licensed and insured crews.
In Hudson, repairs are built to the International Plumbing Code (IPC) that New Hampshire adopts, and the town inspects permitted work.
Before we arrive in Hudson: burst pipe or active leak
Do these in order. Each one takes under a minute.
Find and close the main valve
Look near the meter or where the supply line enters the basement. Turn it fully closed, then open a low faucet to drain the pipes.
Cut power near the water
If water is dripping near a panel, outlet or water heater, turn off those breakers only from dry ground. If you cannot reach the panel safely, say so on the call.
Move what you can
Lift rugs and valuables, and place buckets under drips. Do not tackle a ceiling bulging with water. Leave it for the plumber.
Call the 24/7 line
Dial (603) 815-9179 and tell us if sewage is involved. If the backup is in the street, also call Hudson Public Works or the police dispatch number above.
