Natural Gas Line Replacement Fountain Valley
If your home has old, rusted, or failing gas piping, it’s time for a natural gas line replacement in Fountain Valley. Leaking fittings, pressure drop failures, or outdated materials (like black iron from the ’70s) can all create a safety hazard—and get your gas shut off real fast.
We replace full gas line runs inside homes, out to BBQs, fire pits, heaters, or even all the way back to the meter. Our team uses coated steel, yellow PE pipe, or CSST depending on where the line runs. Every job is tested with pressure gauges and certified before it goes live.
Sometimes SoCalGas flags a line and locks the meter. Other times, a home remodel reveals pipes that are rusted and unsafe. Either way, we’ll walk the route, size the new line, handle permits, and get it installed clean and legal.
Most replacements take a day or two depending on layout and access. Give us a Call(714) 964-3519 or schedule online if you’ve got a gas line that’s past its prime.
Story from Fountain Valley – Full Gas Repipe by Courreges Park
A homeowner near Brookhurst and Nightingale, a block over from Courreges Park, called us after SoCalGas shut off their gas. The main line failed the test and had three visible rust spots at the surface where it entered the crawlspace. Their house was built in 1971, and the original iron piping was finally giving up.
We mapped out a new route using coated steel from the meter into the attic space, dropped new connections to the water heater, stove, and fireplace, and rerouted the line to the backyard BBQ that had been leaking for months. Whole job took 2 days including the city permit inspection.
He was back online and safer than ever—and got rid of the propane tank in the yard too.

How to Prep for a Gas Line Replacement Visit
If you’re getting a full or partial gas line replaced, a little prep helps us keep the job smooth and costs down.
Inside the house: clear access around appliances we’ll be connecting to—like stoves, water heaters, dryers, or fireplaces. Make sure your attic or crawlspace hatch is accessible.
Outside: move patio furniture, grills, and any gear sitting over or near the old gas line. If you know where sprinkler lines or lighting wires run, let us know. And don’t pour concrete, lay new turf, or build anything new until the gas line work is done.
We’ll handle the permits, testing, and final city sign-off.

DIY Gas Line Replacement Mistakes in Orange County
One of the most dangerous mistakes we see? People “replacing” a line without replacing the whole problem. They patch in new pipe where it’s leaking and leave 40-year-old threads in place. That’s like putting a new tire on a cracked rim.
Others reuse old fittings, skip the pressure test, or bury pipe too shallow in the yard. We’ve even seen painters seal around gas piping with caulk, trapping moisture that causes more rust.
If you’re replacing a gas line, it has to be done right—fully, safely, and tested. Otherwise, it’ll fail again

FAQs – Natural Gas Line Replacement Fountain Valley
If your line is leaking due to age, rust, or fails a pressure test—especially more than once—replacement is usually safer and cheaper than trying to patch it again.
Yes. Most gas line replacements require a permit and inspection from the city. We’ll take care of that start to finish.
Basic replacements take a few hours, but full-home reroutes can take 1–2 days depending on access and city inspection timing.
We use PE (poly) for underground lines, coated steel for above-ground rigid piping, and CSST for safe, flexible reroutes indoors.
Yes, and it’s smart. If we’re already replacing the main, adding a stub-out for a BBQ or future pool heater is easy while the system’s open.
