A lot of Spartanburg houses were not built with gas in mind. A bungalow in Hampton Heights or a foursquare in Converse Heights may have heated with coal or oil when it was new, then had gas piped in decades later for a furnace and a water heater. Whatever line went in back then was sized for those two appliances and nothing more.
That history shapes almost every gas line job inside the city. Before we add a range, a dryer, gas logs or a tankless heater, we trace the existing pipe from the Piedmont Natural Gas meter, note what it is made of and how big it is, and work out whether a new branch can tee into it or needs its own run back toward the meter.
The other half of the job is paperwork. Spartanburg addresses straddle two building departments, and the one that permits your line depends on the city limit, not the zip code. We sort that out before the first length of pipe goes in.
Working under an old house
Most early 1900s homes in town sit on brick piers or a perimeter foundation with a crawlspace underneath. That is good news for gas work, because a new line can run along the joists to almost any room without opening finished walls. It also means we see what earlier trades left behind: abandoned pipe, old plug valves and branches capped with a fitting and forgotten.
Dead branches get removed or properly capped, and any old steel that is rusting where it touches a damp pier or the soil gets replaced rather than tied into. A new line is only as sound as the pipe it connects to.
Black iron, CSST and the grounding question
In a crawlspace with long straight runs, threaded black steel is often the simplest choice. Where the route has to snake up through a wall to a second-floor laundry or across an attic, flexible CSST saves dozens of joints.
CSST has to be bonded to the electrical grounding system, and older Spartanburg houses sometimes have grounding that was updated in pieces over the years. We check where the bond can land before choosing CSST, and if the electrical side needs work first, we tell you so you can bring in an electrician.
Mill houses and smaller homes
The mill villages around Spartanburg are full of compact one-story houses, many of them electric for most of their lives. Converting one to a gas range or water heater is usually a short run, since the kitchen and the meter are rarely far apart.
The catch is the service. If the house has no gas at all, Piedmont has to confirm a main is nearby and set a meter before we can pipe anything. We can help you start that conversation, but the meter and the service line are on the utility's timetable.
City permit or county permit
Inside city limits, gas piping is permitted through City of Spartanburg Building Inspections on South Church Street. Outside the line, including plenty of homes with a Spartanburg mailing address, the permit comes from Spartanburg County Building Codes on North Church Street.
Both offices want the line pressure-tested and inspected before it is covered or connected. We look up the parcel, file with the right office and schedule the inspection, so you are not sent back and forth between two buildings on the same street.
In Spartanburg specifically
Historic district exteriors
The city has several historic districts. Gas work that changes the outside of a house, such as moving a meter or adding a wall vent for a new appliance, is worth checking with city planning staff before work starts.
Propane past the mains
Piedmont serves the city and much of the county around it. Homes beyond the end of a main burn propane, so a line there is sized for the propane pressure your supplier sets at the tank.
Basements on sloped lots
Some older homes on sloping lots have a partial basement on the low side. That is often the easiest place to tee in, with the gas line rising through the floor to the room above.
Newer homes at the city edge
Subdivisions on the outskirts were usually plumbed for gas from the start, often in CSST from a manifold near the meter. Adding an appliance there is mostly a question of spare capacity, which we check against the meter rating.
How a gas line install runs
-
Walk the job and add up the load
We look at the meter or tank, the existing piping and every appliance on it, and work out where the new line should tie in and what size it needs to be.
-
Pull the permit
Gas piping is permitted work. We file with whichever building department covers your address, the City of Spartanburg or the county.
-
Run the line
In the right material for each stretch, with a shutoff valve and a sediment trap at the appliance, supported and protected where it passes through framing.
-
Pressure test
The new piping is capped and pressurized with air and held on a gauge. Under the fuel gas code the test is at least one and a half times the working pressure, never below 3 psi, for at least 10 minutes. Many inspectors ask for more. It has to hold with no drop.
-
Inspection
The inspector sees the test on the gauge and checks the installation before anything is concealed or connected.
-
Connect, purge, light and check
We connect the appliance, purge air from the line, light it, and check the flame and the connections for leaks. Every other appliance on the line gets relit and checked as well.
