Gas line work covers running new lines for appliances like ranges, water heaters, and outdoor fire pits or grills, repairing leaks in existing supply lines, capping off lines when appliances are removed, and pressure testing a system before it's reconnected to service. In Cayce, this often means coordinating with SCE&G/Dominion Energy for meter work or final inspections, since gas lines fall under stricter code requirements than most plumbing jobs. Some of the 6 providers listed in this category handle only residential appliance hookups, while others also run commercial gas piping and can pull the permits larger jobs require.
Because a bad connection or an untested line is a safety hazard, not just an inconvenience, this is one area where it pays to check credentials rather than just price. Ask whether the technician is licensed to do gas work specifically (a general plumbing license doesn't always cover it in South Carolina), whether they pull a permit and schedule the required inspection, and whether they pressure test the line and check for leaks with a gauge or approved detection method before calling the job done. A company that skips the permit step to save you time is cutting a corner that matters.
Our scoring weighs licensing, how consistently a company follows proper testing and inspection steps, response time for suspected leaks, and what past customers say about the actual work holding up over time.
