What our gas line installation includes
Every gas line job we run includes the core scope below.

Work order
Gas Line Installation- Permit and inspection: We pull the gas permit with the local authority and meet the inspector on site for final sign-off. You get the paperwork in hand, which matters for insurance and resale.
- Pipe and fittings: Copper pipe, PEX tubing, or CSST, matched to the route and the appliance. Brass fittings, approved sealant, and proper support spacing are included, not billed as extras.
- Pressure test and record: The new line is charged with air and watched on a pressure gauge for the code-required hold. We check every joint with leak-detection solution and give you the test result.
- Appliance connection: We tie the new line into the range, dryer, water heater, grill, or generator, light it, and confirm a clean blue flame. If the flame is yellow or sooty, we correct the air mixture before we leave.
- Shutoff valve and tagging: Every run gets an accessible shutoff valve, tagged so you know exactly where it is. We walk you through how to kill the gas in an emergency before we pack up.

How a gas line install runs, start to finish
Most residential runs take a day or less once we are on site. Here is exactly what happens from your first call to the final inspection.
Tools and methods we use on gas lines
Each method answers a different question. Together they leave very little to guess.
Used to sweat copper joints on gas and water lines. We control heat carefully so we do not scorch framing or set off a smoke alarm in a finished ceiling.
Crimps PEX tubing connections to spec. We check every crimp with a go/no-go gauge so the ring is neither under nor over compressed.
Charges the new gas line with air and holds it for the code-required test period. If the needle moves, we know there is a leak before gas ever enters the line.
Inspects inside walls and crawlspaces for corrosion, rodent damage, or a hidden leak. It lets us confirm the route without opening more wall than necessary.
When Charleston customers call us for gas lines
A homeowner on James Island is switching from an electric range to gas and needs a new line from the meter to the kitchen.
We run a dedicated 1/2-inch or 3/4-inch line through the crawlspace, install a shutoff valve at the range, and pressure-test the run.
HomesA Mount Pleasant family is installing a whole-house standby generator before hurricane season and needs a gas line sized for full load.
We size the run to the generator's BTU demand, run it from the meter to the pad, and coordinate with the electrician…
HomesA Downtown restaurant is adding a commercial range and needs gas piping that meets commercial code in a historic building.

How gas line work runs in Charleston
Gas line installation in Charleston means dealing with three things at once: salt air, old building stock, and a code environment that follows the International Plumbing Code with local amendments. On The Peninsula, we are often working in 1800s homes with tight crawlspaces and no room for a straight run.
Downtown Charleston
Historic homes with tight crawlspaces and no attic access. We route gas lines through existing chases and use CSST where a rigid run will not fit.
West Ashley
Mix of 1960s ranches and newer builds. Slab-on-grade homes often need the gas line run through the attic and dropped down an interior wall.
Mount Pleasant
Newer construction with PEX and CSST already in the walls. Adding a gas line here usually means tying into an existing manifold.

PhotoElectric range swap to gas in West Ashley
Before: A 1970s ranch had an electric range and no gas stub in the kitchen. The homeowner wanted gas but had been told it would require tearing out the ceiling.
After: We ran a 1/2-inch copper line through the crawlspace and up through the cabinet base, avoiding the ceiling entirely. Pressure test held at 10 PSI for the required hold. Inspector signed off the next day.
Undersized tankless line in Mount Pleasant
Before: A tankless water heater was throwing error codes and shutting down mid-shower. The original installer blamed the unit and recommended replacement.
After: We tested supply pressure and found the 1/2-inch line was starving the unit at full draw. We upsized to 3/4-inch, retested, and the unit has run without a single error code since.
Commercial range line in the French Quarter
Before: A restaurant needed a gas line for a new commercial range in a historic building with almost no crawlspace and a narrow service window.
After: We ran the line through an existing chase after close, pulled the commercial permit, and met the inspector the next morning. The restaurant passed on the first walk-through and did not lose a service day.

What Charleston customers say
