Sewer, drain, and pump services across the Seacoast
Most people don't arrive at our website knowing the exact name of the service they need. They know the kitchen sink won't drain, the basement smells like sewage, or the sump pump is making a noise it didn't make last week. This page is built for exactly that moment. It lays out everything Seacoast Sewer and Drain does, organized so you can move from a symptom to the right solution in a few seconds.
We handle the full spectrum of sewer, drain, and pump work for homes and businesses across the New Hampshire and Maine Seacoast, plus grease trap pumping and maintenance for commercial kitchens. We are sewer and drain specialists, not a general repair shop, so the line you call about gets a crew who works these lines all day. Each service below links to a page with the full detail. Start wherever your problem lives, or call us and we'll help you find it.
One team for every layer of your sewer and drain system
Your wastewater system is really three layers working together: the drains inside your home or building that carry water away, the sewer line outside that takes it to the street or septic, and the pumps that move water against gravity when gravity is not enough. When one layer fails, it often shows up as a symptom in another. A slow upstairs drain can be a main-line problem. A wet basement can be a pump issue. A sewage smell can be a venting issue, a cracked line, or a dry trap. In a commercial kitchen, add a grease trap to the picture, and the trap and the drain lines have to be maintained together for the system to hold.
That is why working with a single specialist team across all these layers matters. We can trace a problem from the symptom to its cause instead of fixing one piece and missing the source. Every job starts with an accurate diagnosis, often a camera inspection, so the work addresses the real issue. From there you get upfront pricing, experienced technicians, and 24/7 response when the problem cannot wait. Below, our services are grouped by the part of the system they serve.
Drain services
Your drains are the first place trouble shows up, and usually the easiest to address when caught early. We clear clogs, remove buildup, and find out why a drain keeps backing up rather than just punching through it once.
Drain cleaning
Hydro jetting
Power snaking
Drain camera inspection
Sewer services
The sewer line is the part of your system you never see and can least afford to ignore. A failing line causes backups, foul odors, and, left long enough, property damage. We diagnose, repair, and replace sewer lines with the least disruption the job allows.

Drain excavation
Pump services
Pumps do the work gravity can't, keeping basements dry and waste moving. They also fail quietly, which is why a struggling pump is worth attention before it becomes a flooded basement. We install, service, and repair every common type that runs in a Seacoast home or building.
We work on sump pumps that keep groundwater out of your basement, and sewage and ejector pumps that move waste from below-grade fixtures up to the main line. Unusual noise, constant cycling, weak flow, or a pump that won't start are all signs worth a call. We check the whole setup, the pump, the pit, the float, and the discharge line, then repair or right-size the unit. Learn more
Preventative maintenance and commercial grease trap service
The cheapest service call is the one you do not have to make. Scheduled inspection and the right cleaning on a real cadence catches grease, roots, and pipe issues before they turn into a 2 a.m. backup, and for restaurants and commercial kitchens, keeping the grease trap on a real schedule is the difference between a smooth service and a code violation.

Not sure which service you need?
You don't have to diagnose the problem yourself. Here's a quick guide from symptom to likely service:
- One slow or clogged drain: start with drain cleaning. If it returns, hydro jetting clears the underlying buildup.
- Multiple drains backing up at once: the issue is usually in the main sewer line. A camera inspection finds the cause before anything is dug or cleared.
- Gurgling toilets or sewage odor: often a sign of a sewer line or venting problem. Book a sewer inspection.
- Wet basement or a pump that runs constantly: a pump issue. Schedule pump service before it fails completely.
- Soggy patch in the yard or sewer smell outdoors: a cracked sewer line venting underground. Book a camera inspection.
- Restaurant kitchen with slow drains, an inspection coming up, or an overdue grease trap: book grease trap service and get the trap pumped and the lines cleaned in one visit.
- Recurring problems with no clear cause: a camera inspection plus a maintenance plan usually gets ahead of it.
When in doubt, call (207) 439-2900 and describe what's happening. We'll point you to the right service.
How we work
Every job follows the same straightforward path. First, we diagnose, often with a camera inspection, so we understand the real cause rather than the surface symptom. Second, we explain what we found and give you a clear, upfront estimate to approve before any work starts.
Third, we do the work with experienced technicians and the right tool from the first visit. Every truck carries a jetter, a camera, and the snaking equipment that the call may need, so we match the method to the problem instead of starting small and selling up. Fourth, we confirm the fix holds before we consider the job done. For emergencies, the same process happens fast, around the clock, with a real person answering the phone when you call.

Common questions about our sewer and drain services
Are you a plumbing company?
We are a sewer and drain contractor, which is the specialist you want for clogged drains, backups, sewer line repair, and pump trouble. We do not handle general plumbing like faucets, water heaters, or supply lines. We focus on drains and sewer lines, and we do them well.
What services does Seacoast Sewer and Drain offer?
We cover four areas: drain services (cleaning, hydro jetting, power snaking, camera inspection), sewer services (line repair, replacement, excavation), pump services (sump, sewage, and ejector pumps), and commercial grease trap pumping and maintenance for restaurants and food service, plus preventative maintenance across all of them. Everything runs for both residential and commercial properties across the Seacoast. If you're unsure which fits, call and we'll help.
How do I know whether I need drain cleaning or sewer repair?
One slow drain usually means a localized clog that drain cleaning solves. Several fixtures backing up at once, gurgling, or odor more often points to the main sewer line. The reliable way to tell is a camera inspection, which shows the cause directly so you don't pay for the wrong service.
Do you pump grease traps for restaurants?
Yes. We pump most grease traps and interceptors and clean the drain lines running to and from the tank on the same visit, so grease that clears the trap does not just move downstream. We set the pumping cadence around your actual volume and document every service for your FOG program or health inspector.
Do you offer emergency service across the Seacoast?
Yes. We're available 24/7 for emergencies like sewage backups and failed pumps, including nights, weekends, and holidays. A real person answers the phone when you call. Dial (207) 439-2900 and we'll send a technician. With an active backup, calling sooner generally means less damage and a smaller repair.
Will I get a price before any work starts?
Yes. After we diagnose the problem, often with a camera inspection, you receive a clear, upfront estimate to approve before work begins, with no hidden charges added later. That applies whether it's a quick drain cleaning or a full sewer line replacement.
Do you serve commercial properties as well as homes?
Yes. We work with homeowners and businesses across the region, from residential drain and pump work to grease-heavy restaurant lines, grease trap pumping, and commercial sewer systems. For businesses, we schedule around operating hours when possible to keep disruption low.
What areas do you cover?
We serve the New Hampshire and Maine Seacoast, with priority coverage in Portsmouth, Dover, Exeter, and Durham in NH, plus York, Kittery, and Eliot in ME. We also serve Somersworth, Rochester, Hampton, and the surrounding Seacoast towns. Coverage extends past the listed communities, so call (207) 439-2900 if your town isn't named and we'll confirm.
