Complete sewer and drain service in Portsmouth, NH
At Seacoast Sewer and Drain, we deliver complete sewer and drain solutions for Portsmouth homes and businesses, along with the plumbing repair work that goes hand in hand with them. From a single sluggish fixture to a full sewer line replacement, we come prepared, work cleanly, and stay focused on the long-term fix.
Portsmouth is an old port city, and that shows up in the work we see. Older homes near downtown and the South End run on aging clay and cast-iron pipe that scales, cracks, and attracts roots. Restaurants and bars along the busy blocks push grease through their kitchen lines all day. Property managers run commercial buildings with shared drain systems that take heavy use year-round. We work on all of it, residential and commercial, with the same crew and the same standard.
Our sewer, drain, and plumbing services
Plumbing repair. Leak detection, fixture repair, and pipe repair and replacement for the everyday issues that show up in older Portsmouth homes. We diagnose, fix, and replace what needs it, cleanly and the right way.
Pump install. Sump, sewage, and ejector pumps installed and load-tested before we leave. The right pump for the property, the right discharge line for the weather, no guessing.
Plumbing maintenance. Scheduled service that catches small problems before they become emergencies, fixture checks, line condition, pump testing, and a real cadence built around your property.
Drain cleaning. We clear slow and clogged drains using the right tool for what the line is actually fighting. If a sink, tub, or toilet is backing up in your Portsmouth home, call today for fast, professional service.
Hydro jetting. Pressurized water cuts through grease, scale, and roots in sewer and drain lines, restoring the full diameter of the pipe rather than just opening a path through the blockage. It's the right method for grease-packed kitchens and recurring backups.
Sewer line repair & replacement. From root damage to a lateral at the end of its life, we diagnose, repair, and replace sewer lines when the situation calls for it. Every job starts with a camera inspection, so the recommendation is grounded in what's actually inside the pipe.
Drain camera. Our drain camera shows the inside of your line in real time, revealing cracks, roots, grease, bellies, and collapsed sections. The accuracy saves labor and often prevents an unnecessary dig.
Power snaking. When the problem is one fixture that won't drain, power snaking breaks through stubborn clogs and gets flow back without putting unnecessary stress on the pipe.
Drain excavation. When the line can't be cleared or repaired from the inside, we excavate the section that needs work, keeping the dig as contained as the project allows.

Portsmouth, NH sewer and drain questions, answered
Do you offer emergency drain service in Portsmouth at night and on weekends?
Yes. We answer calls 24/7 across Portsmouth, including nights, weekends, and holidays. Sewer backups and failed sump pumps do not keep business hours, so we keep a line open around the clock. Call (207) 439-2900 and we'll send a technician to your address.
Are you a plumbing company?
We're a sewer and drain contractor first, that's where our specialty sits, and we also handle the plumbing repair work that comes up alongside it, including leak detection, fixture repair, pipe repair and replacement, and pump install. What we don't take on is water heaters, septic tank pumping, and trenchless pipelining, for those we'll point you to the right specialist.
How do I know if my Portsmouth home has a sewer line problem?
Watch for multiple drains backing up at once, gurgling toilets, sewage odors, or water pooling in the yard. In older Portsmouth homes, especially around downtown and the South End, these often point to root intrusion or a cracked line. A camera inspection confirms the cause before any digging, so you aren't paying to guess.
What is hydro jetting, and does my home need it?
Hydro jetting uses high-pressure water to scour the inside of a pipe clean, removing grease, scale, and roots that snaking only punches through. It's a strong fit for recurring clogs and Portsmouth's commercial kitchen lines. We camera the line first to confirm the pipe can handle it.
My sump pump runs constantly. Is that a problem?
Possibly. Some cycling is normal, but constant running can signal a stuck float, an undersized pump, or rising groundwater the system cannot keep up with. We inspect the pump, the pit, and the discharge line, then repair or right-size the unit before a failure floods the basement.
Do you handle commercial drain work for Portsmouth restaurants and businesses?
Yes. We serve restaurants, bars, retail, and commercial properties throughout Portsmouth, including the grease-heavy kitchen lines that need regular hydro jetting and the commercial pump systems behind the scenes. The work runs on your schedule when possible, so service interruptions stay minimal.
Will you give me a price before starting the work?
Yes. You get upfront pricing before any work begins, with no hidden fees added at the end. After we diagnose the issue, often with a camera inspection, you approve the cost first. That holds for routine service and for larger sewer line repairs alike.
How fast can you get to my Portsmouth address?
Response times depend on the day and call volume, but we're based right here in Portsmouth and prioritize emergencies like backups and pump failures. The fastest way to get a firm window is to call (207) 439-2900 and describe what's happening so we can route the right technician.
What kinds of pumps do you install and repair?
We install and service sump pumps, sewage pumps, and ejector pumps. Each does a different job. If yours is running rough, cycling oddly, or not running at all, call to schedule an inspection before it fails.
