Commercial Sewer and Drain Services Across the NH and ME Seacoast
Commercial sewer and drain services across the NH and ME Seacoast
Keep your kitchen, restrooms, and main lines flowing, with the right tool from the first visit.
A backed-up line shuts a business down fast. When a kitchen drain stalls during the dinner rush or a property's main line backs up across units, you need a crew that shows up, finds the real problem, and clears it right the first time. Seacoast Sewer and Drain handles commercial drain cleaning for restaurants, hotels, and property managers across the New Hampshire and Maine Seacoast.
Our technicians carry the right equipment on every truck, from power snaking for a single stubborn fixture to hydro jetting for grease-packed and root-filled lines. We diagnose first with a drain camera, so you are paying to fix the actual blockage, not to guess at it.
Whether it is one floor drain or a recurring main-line backup that other crews could not solve, you get straight answers, clean work, and honest pricing before we start.

Commercial sewer & drain service across the Seacoast, NH and ME
Across the Seacoast, from Portsmouth, Dover, Exeter, and Durham in New Hampshire to Kittery, Eliot, and York in Maine, commercial lines take a beating. Restaurants push grease and food solids through their drains all day, hotels run heavy laundry and guest loads, and older downtown buildings hide clay and cast-iron pipe that tree roots love to invade.
In most commercial buildings here, the culprit is the same: fats, oils, and grease that cool and harden inside the line until flow chokes down. Grease is the leading cause of sewer backups in food-heavy areas, and a quick snaking alone rarely keeps it from coming back.
Our approach to commercial drain cleaning starts with pinpointing the problem. We test fixtures, find the cleanout, and run a camera when symptoms point deeper, then clear the line with the right method: targeted snaking for a single fixture, or hydro jetting for grease and roots in the main line. If we find a damaged or collapsed section, we document it and walk you through the options, including sewer line repair and, when a dig is the honest fix, excavation.
Our 3-step commercial sewer & drain process
1) Diagnose & locate
We test fixtures, open the cleanout, and run a drain camera when symptoms suggest a main-line or buried-pipe issue. You see exactly where the problem is and what is causing it, whether that is grease, roots, scale, or a sag in the line.
2) Clear it the right way
For a single slow fixture, we use power snaking to restore flow without tearing up the pipe. For grease-packed lines or recurring commercial backups, we run hydro jetting to scour the pipe walls clean, not just punch a hole through the clog.
3) Verify & prevent
We confirm full flow, check the venting that causes gurgling, and lay out a simple plan to keep the line clear, including scheduled preventative maintenance for grease-prone kitchens. If we find damage, we cover repair options and timelines honestly.
Understanding commercial grease and drain problems (and why DIY rarely holds)
In a commercial kitchen, the problem is almost never one bad day. It is the slow buildup of fats, oils, and grease coating the inside of your lines until flow chokes down, and grease is the single most common reason commercial drains back up.
Left alone, that grease narrows the pipe until it has to be replaced years earlier than it should, and the worst backups land in exactly the kitchens that run hardest. A store-bought enzyme or a quick auger run only masks it, because the grease reforms downstream within weeks.
Professional commercial drain cleaning pairs camera diagnostics with the right clearing method, snaking for localized stoppages and hydro jetting for grease and scale, so the line ends up clean, not just temporarily open.
When to call a pro instead of waiting
- Multiple fixtures backing up at once: usually a main-line restriction, not a single drain.
- Slow drains during peak service hours: often grease or scale narrowing the line.
- Recurring clogs in the same kitchen line: a sign the pipe needs jetting, not another snaking.
- Sewer odors in the dining room or restrooms: may point to a dry trap, a venting issue, or a break that needs a camera.
- Older downtown buildings with clay or cast-iron pipe: high risk of root intrusion and collapse, worth a camera inspection.

Common questions about commercial sewer & drain service
1) How often should a commercial kitchen have its drain lines cleaned?
It depends on volume and how much grease the kitchen produces. High-output kitchens usually benefit from scheduled jetting on a regular cycle, and we set that cadence after a camera check rather than guessing.
2) What is the difference between snaking and hydro jetting for a commercial line?
Snaking clears a localized clog and gets flow back fast. Hydro jetting scours the full pipe wall of grease and scale, which is what recurring commercial backups usually need.
3) Do you work around our business hours?
We schedule around your service hours wherever possible and run 24/7 for emergencies, so a backup does not have to wait until morning.
4) Can you clear a grease-packed main line without digging?
Usually yes, with hydro jetting. We only recommend excavation when the pipe itself is broken, collapsed, or out of pitch.
5) How do we know if it is our line or the city main?
Multiple fixtures backing up and wastewater surfacing at the lowest drains usually points to the building's main line. A camera inspection confirms it before anyone starts work.
6) Do you handle property management portfolios?
Yes, single buildings or multiple units. We document what we find so managers can plan repairs and budget instead of reacting to one emergency at a time.
7) What causes recurring commercial backups?
Grease, food solids, flushed wipes, root intrusion in older lines, or a belly where the pipe sags and collects waste. We identify the actual cause so it stops repeating.
8) What if the camera finds a broken line?
We document it and walk you through the options, from a targeted dig to a full sewer line replacement, with honest timelines and no pressure.
