Pipe and Sewer Repair: Leaks, Breaks, and Frozen Lines
A leaking pipe inside a commercial building can damage ceilings, flooring, and inventory before anyone notices, especially overnight or over a weekend when the building is empty. Our plumbers find and repair leaks in supply lines, drain lines, and fixtures. Outside the building, we repair and replace damaged sewer lines that carry waste from your property to the public sewer.
Temperatures in Durham regularly fall below freezing on winter nights. Pipes in unheated spaces are most at risk, including loading docks, warehouses, storage rooms, and lines that run along exterior walls. Water expands as it freezes, which can split a pipe, and the leak starts once the ice thaws. You can lower the risk by keeping heat on in vacant suites and insulating exposed lines. If a pipe does break, our team handles frozen and burst pipe repair.
Water Heaters and Gas Lines: Hot Water and Fuel for Daily Operations
Restaurants need hot water for dishwashing and handwashing sinks, and salons, gyms, and offices need it for customers and staff. Water heaters are one of our specialties, and we repair and replace them for commercial buildings. When it is time for water heater installation, the new unit should match how much hot water your building uses at its busiest time of day. A unit sized that way keeps up through a lunch rush or a full class schedule.
We also install and repair gas lines that feed water heaters, furnaces, and kitchen equipment. A gas line sized for the original kitchen may not carry enough fuel once you add a range or a fryer. On an undersized line, burners can burn with weak flames when everything runs at once. Before you add gas equipment, have us confirm that the line can carry the extra load.
Drain Service: Clearing Clogs and Finding What Caused Them
Drains in a commercial building handle more waste than household drains do. Kitchen lines collect grease and food scraps, and restroom lines carry paper and steady use from customers and staff. When a line backs up, our plumbers provide drain clearing to open the blockage and get water moving again. For kitchen lines coated in grease, hydro jetting sprays high-pressure water through the pipe to scour the walls. A drain cable only punches a hole through that buildup, while jetting removes it.
When the same drain keeps backing up, a camera inspection shows what is inside the line. Our plumbers run a waterproof camera through the pipe to look for tree roots, a sagging section that collects waste, or a crack. Once we see the cause, we can repair it instead of clearing the same clog again.

FAQs
What should we do first if a pipe bursts in our building?
Take these steps right away:
- Shut off the main water valve to stop the flow.
- If you can reach the breaker panel without standing in water, turn off power to any area where water is near outlets, lights, or equipment.
- Move inventory, files, and electronics out of the water’s path.
- Call us to schedule the repair.
If you are not sure where your main shutoff valve is, ask our plumber to show you at your next service visit.
How often does a backflow preventer need to be tested in Durham?
Water utilities in Durham and across the Triangle require testable backflow prevention assemblies to be tested once a year. A certified tester has to perform the test, and the results are reported to the utility. If your building has more than one assembly, such as one on the main water line and another on an irrigation line, each one needs its own test.
Is a tankless water heater a good fit for a business?
A tankless water heater heats water as it flows through the unit, so it does not run out during long use and does not keep a full tank hot overnight. That suits offices and shops where hot water use is light and spread through the day. A restaurant running a dishwasher and several sinks at the same time can need more hot water than one unit produces. Those buildings may need several tankless water heaters linked together or a storage tank.
Why is the water pressure low in one part of our building?
When pressure is low in one area only, the cause is likely on the pipes that serve that area. Possible causes include a partly closed valve, mineral buildup inside older galvanized pipe, or a hidden leak. When pressure is low throughout the building, the cause is more likely the main water line, the pressure-reducing valve, or the water service from the street. During a water pressure assessment, we measure pressure at different fixtures to find where the drop begins.
What causes a sewer smell in a commercial restroom?
Floor drains and rarely used fixtures have a trap, a bend in the pipe that holds water to block sewer gas. When a drain goes unused for weeks, that water evaporates and the gas can come up through the drain. Pouring a bucket of water into the drain refills the trap. If the smell continues with every trap full, a cracked vent pipe or a failed seal under a toilet may be letting sewer gas into the room. Our plumbers can track down the source.
