Sump Pump Installation and Repair Across the NH and ME Seacoast
Sump pump installation and repair across the NH and ME Seacoast
A pump that fails on the wrong day is a flooded basement. We install, repair, and replace pumps that hold up to Seacoast weather, the first time.
A sump pump is one of those quiet pieces of equipment that does its job for years until the day it doesn't. When that day shows up, usually during a heavy spring melt or a hard rain event, the difference between a dry basement and four figures of water damage is whether the pump kicks on. That's the work Seacoast Sewer and Drain shows up for.
We handle the full range of pump work: new sump pump installations in basements that need one, replacements when the existing pump is at the end of its life, and repairs when something's failing but the system is still worth saving. We work on sump pumps, sewage pumps, and ejector pumps, and we tell you straight which one your situation actually calls for.
When the pump on your floor is older than seven or eight years, runs constantly in dry weather, or makes noise it didn't make last spring, that's the time to call. Catching it before a heavy rain costs a fraction of what a basement flood costs after one.
Why Seacoast homeowners trust us with pump work
- We test under real load - not a quick visual check, an actual run with water to confirm the pump activates, discharges cleanly, and shuts off right.
- Right pump for the property - we size based on the basement, the water table, and the discharge run, not whatever's on the truck.
- Battery backup expertise - we install and service secondary pumps that keep working when household power doesn't.
- Discharge line work included - we don't fix the pump and leave a frozen discharge to fail next month.
- Honest repair-versus-replace calls - if a repair makes sense, we make it. If the motor is gone, we tell you straight.
- Experienced on Seacoast basements - our lead tech has 15-plus years on the region's wet basements and aging pumps.
- 24/7 emergency response - a flooded basement at midnight gets the same answer it would at noon.
- A real person on the phone - someone in the office answers when you call, every time.
Why Seacoast homes lean so hard on their pumps
From Portsmouth, Dover, Exeter, and Durham in New Hampshire to Kittery, Eliot, and York in Maine, basements across the Seacoast take a beating from groundwater. Heavy spring snowmelt, coastal rain events, and freeze-thaw cycles all push water toward older foundations that were never built for modern weather patterns. The sump pump is often the only thing standing between a dry basement and a real problem.
What we see on service calls is consistent. Older homes carry pumps that have been there too long, often installed by a previous owner and never tested. Newer homes carry undersized pumps that handle normal rain fine but can't keep up with a real event. And almost every Seacoast basement we see lacks a battery backup, which is exactly the failure mode that produces the worst floods.
We work through all of it. New installs, full replacements, motor and float repairs, discharge line fixes, and battery backup additions. The goal is the same every time: a pump that does its job when the weather is at its worst.
Our 3-step pump service process
1) Diagnose under load
We don't trust a pump that looks fine sitting still. We pour water into the pit, watch the float trigger the pump, confirm the discharge clears cleanly, and listen for grinding, vibration, or a motor working harder than it should.
2) Repair or replace, honestly
If a float, check valve, or discharge fitting is the problem, we repair it. If the motor is at the end of its life or the pump can't keep up with the basement, we tell you straight that replacement is the smarter spend.
3) Install, test, and verify
When the new pump goes in, we run it through full operation before we leave. The float triggers, the discharge clears, the shutoff is clean. You see it working before we pack up.
Repair, replace, or upgrade? How we read the pump in front of us
Not every struggling pump needs to be replaced. A failed float, a stuck check valve, or a frozen discharge line are all repairs, and we make them all the time. But a pump that's eight years old, runs constantly even in dry weather, or has a motor that's running hot is a pump that's not getting through another winter, and patching it just postpones the replacement.
We base the call on what we see under load. A pump that triggers crisply, discharges cleanly, and shuts off without hesitation usually has years left. A pump that hesitates, grinds, or runs without moving water is on borrowed time.
Signs your pump is the problem
- Pump runs constantly in dry weather: float is stuck or the pump is short-cycling, both of which burn out the motor.
- Pump runs but no water moves: impeller, discharge line, or check valve is blocked.
- Grinding, rattling, or burning smell: bearings or motor is failing, replace before the next heavy rain.
- Basement still gets wet despite a working pump: the pump is undersized, the pit is in the wrong spot, or the discharge is failing.
- Pump older than seven to ten years: even working pumps reach the end of their service life.
- No battery backup in a finished basement: the next power outage is the test you don't want to fail.

Common questions about sump pump installation and repair
1) How do I know if my pump needs to be replaced?
The signs to watch: constant running, grinding noise, water in the pit that rises higher than usual before the pump kicks on, or a pump older than seven to ten years that's never been load-tested. Any of those is worth a service call before peak season.
2) Do you install battery backup pumps?
Yes. For any home with a finished basement, a history of flooding, or a high water table, a battery backup is one of the highest-value upgrades available. We install backups alongside the primary pump in the same pit.
3) Can you fix my pump or do I always need a new one?
Depends on what's wrong. A failed float, a stuck check valve, or a frozen discharge line are repairs we make all the time. A burned-out motor or an end-of-life pump needs replacement, and we tell you straight which one you're looking at.
4) How long does a typical sump pump installation take?
Most residential pump installations are a few hours start to finish, including testing under load before we leave. A more complicated install (new pit, discharge line work, battery backup) takes longer, and we give you a realistic timeline up front.
5) What pump should I get for my basement?
It depends on the size of the basement, the water table, the discharge run, and whether the basement is finished. We size the pump to the property, not to what's cheapest on the truck.
6) Do you handle sewage and ejector pumps too?
Yes. We install, service, and replace sewage pumps and ejector pumps alongside standard sump pumps. The diagnostic approach is the same, the equipment is different.
7) My discharge line keeps freezing in winter, can you fix that?
Yes. Discharge line freezing is one of the most common winter pump failures on the Seacoast, and it's almost entirely preventable. We repair, reroute, and install freeze-resistant fittings as part of the work.
8) Can a flooding basement wait until tomorrow?
No. If the pump is failing during an active water event, the longer it sits, the more damage compounds. We run 24/7 for exactly that reason.
