The most important fact on this page: Duncan is not served by Piedmont Natural Gas. The gas utility here is the Greer Commission of Public Works. If you smell gas, get everyone out of the house, then call 911 and Greer CPW at (864) 848-5500. CPW says its technicians are on call around the clock.
People who have moved to Duncan from elsewhere in Spartanburg County sometimes reach for the Piedmont number by habit. It is worth saving CPW's number in your phone today, next to ours.
Greer CPW repairs its own main, service line and meter. If the leak is in your piping or at an appliance, the technician will make it safe and leave the repair to a licensed contractor. We answer at any hour, find every leak on the house side of the meter, repair it and prove it with a pressure test.
Duncan is a short run from our base in Spartanburg, down I-85 or US 29.
Your first moves in Duncan
Leave without flipping switches, unplugging anything or starting a car in an attached garage. Do not use your phone until you are outside and away from the smell. Leave the doors as they are.
- From outside: call 911, then Greer CPW at (864) 848-5500
- On propane instead: call 911 and your propane supplier
- Stay out until CPW or emergency responders say it is safe
- Then call us to repair any leak past the meter
What leaks in newer Duncan homes
Most of Duncan's housing is young, so corroded pipe is less common than in older towns. The leaks we look for first are at connections that get handled: the flexible connector behind a range that was pulled out for cleaning, the dryer connector reused when the dryer was replaced, and the union at a water heater that was swapped.
Tankless conversions are another source. A conversion adds new joints at the heater and sometimes along a new branch in the attic. If the smell began after that kind of project, we test that work first.
With the gas off and every appliance closed, the small test dial on the Greer CPW meter should not move. If it creeps, gas is going somewhere on your side, and we keep testing until we know where.
Older piping near the old town center
Homes near Main Street that predate the town's growth may have black steel through a crawlspace, extended a piece at a time as appliances were added. Rust where pipe meets soil or masonry, old valves at abandoned appliance stubs, and joints opened during past repairs are the usual suspects.
In those houses, we isolate sections of the system and pressure-test each one, then pin down the exact fitting with a detector and bubble solution.
Yard lines and SC811
Patio grills and fire pits in newer Duncan neighborhoods are often fed by buried plastic gas lines. Fence posts, irrigation and landscaping can find them. Because those lines are on the house side of the CPW meter, SC811 does not mark them.
A tracer wire buried with the pipe lets us trace its route with a locator. Then we repair the damaged section, test it and restore service to the grill.
If there is no tracer wire, we add one when we repair the line, so the next person who digs in that yard has a way to find it.
Back in service
Every repair is tested with the piping pressurized and held on a gauge with no drop for the code minimum time. Larger repairs, such as replacing a run of pipe, are permitted through the Town of Duncan inside town limits. Then we coordinate with Greer CPW if the meter was shut off, purge the lines, relight each appliance and check every connection we touched.
In Duncan specifically
Greer CPW emergency line
CPW lists (864) 848-5500 for reporting gas emergencies, with technicians available around the clock. Its guidance is to call 911 first, then CPW.
Town of Duncan permits
Repairs that replace pipe are permitted by the town's building official. Beyond the town line, the county's Building Codes office takes over.
Attic CSST
In slab homes, gas often runs through the attic in CSST. A leak there can be hard to smell from the rooms below, so we test that section on its own.
Gas alarms
A listed natural gas alarm near appliances adds a layer of warning. It is separate from, and no substitute for, carbon monoxide alarms.
How a gas leak call runs
-
You get safe and call the utility
Leave the house, call 911 or the utility from outside, and wait for them to make the area safe and shut off gas as needed.
-
You call us, any hour
Tell us what the utility found and whether there is a red tag. A person answers day and night.
-
Locate every leak
Electronic detection, leak solution and pressure decay testing, section by section, until we know where every leak is, including any the utility did not flag.
-
Explain the repair
We show you the leak, explain what failed and why, and walk through the repair before we start.
-
Replace the failed parts
Leaking fittings, valves, connectors or pipe are replaced with the correct material for the location.
-
Pressure test
The repaired system is tested to the fuel gas code minimum and must hold with no drop.
-
Restore service and relight
We purge the lines, coordinate with the utility if the meter was locked, relight every appliance and check each one for leaks.
