Pool Heater, Fire Pit and BBQ Lines in Williston, ND
Outdoor living is a big part of many homes, and many backyards have gas lines for pool heaters, fire pits and built-in grills. These lines face sun, weather and irrigation water that cut their life.

Buried Yard Line Repair and Replacement in Williston, ND
Many older homes have steel gas lines running from the meter to the house or to a pool heater. Over time the wrap fails and the pipe corrodes, especially where sprinklers keep the soil wet. We call 811 to mark utilities before digging, then replace the line with polyethylene pipe and tracer wire or coated steel as required. Trenching is backfilled and the yard is cleaned up when we are done.
Corroded & Damaged Gas Pipe Replacement in Williston
Over time, ground movement and moisture can cause underground gas lines to corrode or become damaged, along with tree roots and age. Heavy, expansive clay soils are common in North Dakota, and they swell and shrink with moisture and frost, stressing foundations and buried pipe. We specialize in replacing compromised sections of gas piping, using durable materials like polyethylene (PE) for underground lines or black iron pipe for exposed sections, all installed to current code. Our repairs prevent future leaks and protect the long-term reliability of your gas supply in Williston.

Gas Leak Detection in Williston
A rotten egg smell, hissing near a line, dead plants over a buried pipe or a gas meter that moves with everything off are classic leak signs. We isolate sections of the system and use electronic combustible gas detectors to narrow the source. Soap solution confirms leaks at fittings, valves and unions. Once we find the leak, we give you a written repair price before starting.
