Sewer and drain service in Portsmouth's older neighborhoods and downtown

At Seacoast Sewer & Drain, we handle sewer and drain work for Portsmouth homes and businesses, from a single slow fixture to sewer line problems.

Portsmouth's mix of older homes and downtown businesses shapes the calls we get. Older drain lines made of clay or cast iron can crack, scale, or let roots in. Restaurants and bars send grease through their kitchen lines, which is a common cause of commercial backups. The city's own sewer system is old too: the Public Works department says some of its pipes are more than 100 years old. We work on the drain and sewer lines on your property, residential and commercial, and a camera inspection helps show where a problem is.

Here is what we can help with in Portsmouth: drain cleaning, hydro jetting, and power snaking for clogged and grease-heavy lines; drain camera inspections to see the condition of older lines; sewer line repair and replacement; grease trap cleaning for restaurants and other commercial kitchens; sump, sewage, and ejector pump installs; and septic tank work for properties that are not on the city sewer. We also replace toilets and handle simple fixes that turn up during a drain call, but general plumbing is not our focus.

When a line cannot be cleared or repaired from the inside, we can excavate the section that needs work.

Portsmouth, NH sewer and drain questions, answered

Do you offer emergency drain service in Portsmouth at night and on weekends?

Yes. We run 24/7 for emergency calls in Portsmouth.

Are you a plumbing company?

We're a sewer and drain contractor first, and that's where our specialty sits. We don't do much general plumbing beyond what turns up during a drain call, such as replacing a toilet or making a simple repair. We also clean grease traps and do septic tank work. For water heaters and trenchless pipelining, 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.

Does the age of my Portsmouth home affect my drain line?

It can. About 61% of owner-occupied homes in Portsmouth were built before 1960, and older drain lines may be made of clay or cast iron, which can crack or let roots in. A drain camera shows the condition of your line, so the cleaning or repair matches what is actually there.

Do you handle commercial drain work for Portsmouth restaurants and businesses?

Yes. Downtown Portsmouth has a lot of restaurants, bars, and shops, and grease is a common cause of kitchen line backups. We do commercial drain work and clean grease traps, mostly smaller ones.

Will you give me a price before starting the work?

Yes. You hear the price before any work begins.

How fast can you get to my Portsmouth address?

Call us and we will tell you what to expect for your address. We run 24/7 for emergency calls.

Is my Portsmouth property on city sewer or septic?
