What to expect with Seacoast Sewer and Drain

We bought this company three years ago to do the work the right way. That shows up in the small things. A real person answers the phone. The technician shows up with the equipment the call actually needs. The diagnosis is honest, even when the honest answer is that the fix is smaller than you thought. There is no upsell to a service we do not do.

  • Fast response, 24/7 availability — when you need emergency drain service, we are on call around the clock to stop the damage before it spreads.
  • Right tool from the first visit — every truck carries a jetter, a camera, and the right snaking equipment, so we match the method to the clog instead of starting small and selling up.
  • Comprehensive sewer and drain work — from a single slow fixture to a full sewer line replacement, under one team.
  • Upfront pricing, no surprises — clear, transparent quotes, no hidden fees added at the end.
  • Long-lasting results — we fix the cause, not just the symptom, so the same line does not come back next month.
  • Customer-first approach — we treat your home or business the way we would want ours treated, clean work, clear communication, no pressure.

Reviews from Portsmouth, the Seacoast, and beyond

Proudly serving Portsmouth, Dover, Exeter, and Durham in New Hampshire, plus York, Kittery, and Eliot in Maine, along with the surrounding Seacoast towns. Read what our neighbors say about working with the team.

We needed new pumps in our commercial septic system in Hampton Falls. Needless to say we needed a quick response. Seacoast Sewer was there quickly. They were friendly and professional. We are pleased. We will certainly use them again.

The job was completed in a timely manner. The tech and the manager made adjustments to the billing due to issues with the old house plumbing that could not be resolved. Things seem to be working out as expected. Would use them again.

We had a drain pipe overflow and within an hour the Seacoast crew was at our door and had the issues fixed within another hour. The were friendly, respectful, and incredibly helpful and knowledgeable.

Fast, effective, clean, affordable service from these guys. They fixed my drain issue hasn’t been a problem since! I definitely recommend sea coast sewer and drain

Professional, excellent and detailed. Couldn’t believe how clean and neat. They left our property after they completed the work in a timely fashion.

They are awesome.  We had a backup that no other plumbers wanted to touch.  One call and a half hour later they we there. Never calling another plumber, ever!

Professional, on time and very friendly. Seacoast Sewer & Drain impressed with their knowledge and quick resolution of my problem. I would gladly use them again.

We had a clog in the kitchen sink drain line and called in the morning. Seacoast Sewer & Drain got here promptly and resolved the issue fast!

The gentleman that work for this company, such as Nick and BOB are very professional, caring and loyal to their customers. Super reasonably priced as well!!

How a sewer and drain call actually works here

Most people only think about their sewer and drain lines when something is already wrong. By then the call is urgent, and the question is not whether you need help, it is who you want showing up. Here is what working with us actually looks like.

First, we listen. You tell us what is happening, which fixtures are affected, how long it has been going on, what you have already tried. That alone narrows the diagnosis before we get to the property.

Then we diagnose, with the right tool. For a simple single-fixture clog, that is usually a snaking call. For whole-house backups, recurring clogs, or anything pointing to the main line, a drain camera earns its keep by showing the cause directly. No exploratory digging, no guessing.

Then we explain your options. You see what the camera saw. We walk you through the smartest fix and the honest pricing, including when a smaller fix is the right call and a bigger one would just be us selling you work.

Then we do the work. Whether that is a plumbing repair, power snaking a branch line, hydro jetting a grease-packed main, repairing a damaged section of sewer line, or coordinating a targeted dig, we run the job cleanly and confirm the work holds before we leave.

Why homeowners and businesses choose Seacoast:

  • 24/7 emergency drain service, real-person response when minutes matter
  • Accurate diagnostics with video camera inspection and precise pipe locating
  • Right tool from the first visit, from snaking to jetting to excavation
  • Long-lasting results from preventative maintenance plans for older homes and grease-heavy commercial kitchens
  • Respect for your property, clean work areas, and clear communication
