Repair or replace: how we help you decide
A repair makes sense when the failed part is cheap and the rest of the system is sound. Replacement makes sense when the same fixture or pipe has failed more than once, or when the repair costs a large share of a new unit. The plumber explains both options and the price of each before work starts.
| Situation | Usually repair | Usually replace |
|---|---|---|
| Water heater | A failed element, thermostat or valve on a young tank | A tank that leaks from the shell or is well past its expected life |
| Drain line | A clog from grease, hair or paper | A collapsed or badly offset section of pipe |
| Supply piping | One pinhole leak in otherwise sound pipe | Repeated pinholes or heavy corrosion throughout |
| Toilet | A worn flapper or fill valve | A cracked bowl or tank, or a rocking base that damaged the floor |
These are general patterns, not a diagnosis. Your plumber looks at your actual pipes and tells you which side of the line you are on.
What emergency service means here
Services marked as emergency work are covered by the 24/7 line, which is answered at night, on weekends and on holidays. The dispatcher asks what is happening, tells you what to shut off, and schedules a licensed plumber. Planned work such as water heater installation or repiping is booked for a time that suits you, and same-day appointments are available when the schedule allows.
If you smell gas, leave the building and call 911 or the gas utility first. Plumbers do not respond to gas emergencies before the utility has made the area safe.
Not sure which service you need?
Describe the symptom to the dispatcher. A meter that keeps running points to leak detection, a gurgling tub points to a drain or sewer problem, and a tank that rumbles points to a water heater. You do not need the right name for the problem to get the right plumber.
We also serve nearby towns. See the service area page for Derry, Windham, Hudson, Manchester and Litchfield.

The urgent ones do. Planned work such as water heater installation, repiping and sewer inspection is scheduled, though same-day appointments are available when the schedule allows.
Drains, sewers and backups
Clogs and backups are the most common after-hours calls. Start here if water is coming up instead of going down.
Drain Cleaning
Slow sinks, gurgling tubs and kitchen lines that back up. We use augers, cables and a camera to find and clear the blockage.
Hydro Jetting
Pressurized water scrubs the inside of the pipe when a cable only opens a small channel and the clog keeps coming back.
Sewer Line Cleaning
For main-line backups, we run heavier equipment to remove roots, grease and paper between the house and the street or tank.
Sewer Line Repair
Cracked, offset or root-damaged sewer pipe repaired with spot digs, trenchless lining or replacement.
Sewer Inspection
A video camera shows the pipe before a home purchase, a dig or a repeat backup, so decisions rest on what is actually there.
Leaks, bursts and water lines
When water is where it should not be, the first job is stopping it, and the second is finding where it started.
Leak Detection
A running meter, a warm floor or a wet ceiling means water is going somewhere. We trace it with sound and moisture tools.
Burst Pipe Repair
A split or frozen pipe needs the water stopped first and the pipe fixed second, with advice on drying out.
Water Service Line Repair
Problems with the line from the street main or well to your house, including low pressure and a leaking shutoff.
Repiping
Galvanized or failing supply lines replaced room by room or throughout, when patching has stopped making sense.
Water heaters
A failed heater is both an emergency and a planning decision. These pages help you choose repair or replacement.
Water Heater Repair
No hot water, lukewarm water, rumbling or a drip at the tank. We find the failed part and tell you if repair still pays.
Water Heater Replacement
When a tank has rusted through or repair bills pile up, we replace it and haul away the old unit.
Water Heater Installation
Planned installs with the right venting, shutoff valves and expansion tank for your home.
Tankless Water Heater
Wall-hung on-demand heaters installed, serviced and flushed to keep scale from shortening their life.
Fixtures, installs and commercial
Everyday fixtures, new installs and after-hours work for businesses.
Toilet Repair and Installation
Running, leaking, weak-flushing or rocking toilets repaired, and new toilets set on a sound flange.
Faucet Repair
Drips, stuck handles and shutoff valves that will not close, plus leaking tub and shower valves.
Garbage Disposal Repair
A humming or jammed disposal fixed or swapped, with the drain and dishwasher connection checked.
Plumbing Installation
Fixtures, remodel rough-ins and new-construction plumbing installed cleanly and tested before we leave.
Commercial Plumbing
Plumbing help for businesses, including after-hours leaks, drain backups and building water systems.
