When You Need a New or Replacement Gas Line

Most gas line projects start with a plan, not an emergency. These are the jobs we are called for most often:

  • A new gas range, cooktop or dryer in a house that only has electric hookups.
  • An outdoor kitchen, BBQ, fire pit or patio heater that needs a line buried to code depth.
  • A pool or spa heater, a standby generator or a tankless water heater that needs a larger supply.
  • A remodel or addition that moves appliances and needs the gas piping rerouted.
  • Original black iron piping from the 1960s to 1980s with corroded fittings, ready for a full gas repipe.
  • A home sale or insurance inspection that flagged old flex connectors or missing sediment traps.

New appliances also change the load on your system. A tankless water heater or a generator can need more gas than your existing pipe and meter can deliver, so we size every line for the total BTU demand of the house, not just the new appliance.

If you smell gas or a line has already failed, that is a repair, not a project. See our gas leak and gas line repair page or call us 24/7.

From a Single Appliance Line to a Complete Gas Repipe

Gas line work ranges from a quick hookup to a full-system overhaul. Here’s what we handle:

New Gas Line Installation

Adding a gas range, dryer, fireplace, outdoor grill, or pool heater? We run new gas lines from your existing supply, properly sized for the BTU demand of your appliance. Every new line is pressure-tested and permitted.

Gas Line Replacement

Undersized pipe, corroded runs or a section that has been patched before: we replace the affected run with new pipe sized for today's appliances, then pressure-test the entire system before the gas goes back on.

Whole-Home Gas Repiping

Older Sacramento homes with original black iron gas pipe are prone to micro-leaks at every threaded joint. When the system is aging out, replacing individual sections becomes a cycle of diminishing returns. A full gas repipe with modern CSST (corrugated stainless steel tubing) or updated black iron eliminates the risk and brings the entire system up to current code.

Load Calculation & Meter Upgrades

Before we add an appliance, we total the BTU demand of every gas appliance in the house and check it against your pipe sizing and meter capacity. If the meter is too small, we coordinate the upgrade with PG&E so the new appliance runs at full output.

What to Expect — From Assessment to Pressure Test

Gas line work requires precision and zero shortcuts. Here’s how every gas project works with 5-Star Plumbing:

System Assessment

We inspect your existing gas lines, check the meter capacity, evaluate the condition of fittings and connections, and determine whether you need a repair, a new line run, or a full repipe.
Step 1

Flat-Rate Quote

One price covering materials, labor, permits, and the final pressure test. For new appliance hookups, we also confirm that your meter and supply line can handle the added BTU load.
Step 2

Permits & Coordination

We pull the required city permit. For work that involves shutting off gas to the meter, we coordinate the timeline so you’re never without heat or hot water longer than necessary.
Step 3

Installation & Pressure Test

We install or replace the gas lines, connect all appliances, and run a pressure test on the entire system. The test holds for a specified duration at a set PSI — if it holds, the system is sealed. If it doesn’t, we find and fix the issue before any gas flows.
Step 4

City Inspection & Gas Turn-On

We schedule the city inspection, meet the inspector on-site, and once the work passes, coordinate with PG&E to restore gas service. You get documentation proving the work is code-compliant and on record.
Step 5

Why Sacramento Homeowners Trust Us With Their Gas Lines

Licensed and Permitted

Gas line work without a permit is illegal in California and dangerous to your family. Every gas project we do is permitted by the city and passes a formal inspection. No exceptions, no shortcuts.

Pressure-Tested, Every Time

Before gas flows through any pipe we’ve touched, we run a pressure test to prove the system is sealed. This isn’t optional — it’s how we guarantee your family’s safety.

Upfront Flat-Rate Pricing

Gas work can be complex, but the price shouldn’t be a mystery. You approve the total cost before we start — materials, labor, permits, and testing included.

In-House Technicians Only

We never subcontract gas line work. The technicians who assess your system are the same ones who install, test, and stand behind the finished job.
