What Gas Line Repair and Installation Services Do We Provide?

A tech talking to a customer.

On Time Experts Heating, Air & Plumbing repairs leaking or damaged gas piping and adds new lines for gas appliances. Spire supplies natural gas here and, in most cases, owns the line up to and including the meter. The piping past the meter belongs to the homeowner.

You need gas line repair when Spire or a technician has found a leak and shut off or tagged the line, or when old piping, valves or connectors need replacing. You need gas line installation when you switch to a gas range, add a gas dryer or tankless water heater, or want a gas grill or generator.

If you smell gas right now, don't book a visit. Get everyone out of the house without touching switches, then call Spire or 911 from outside. The full steps are below.

What Is Included in Our Gas Line Repair and Installation Services?

The work includes:

  • Gas leak repair: Locating the leak at joints, fittings and valves, then repairing or replacing that section.
  • Pressure testing: Testing new and repaired lines before gas is turned back on.
  • New gas lines: Lines sized for ranges, dryers, water heaters, furnaces, fireplaces, outdoor grills and standby generators.
  • Shut-off valves: Adding valves where they're missing.
  • Appliance connectors: Replacing old connectors with new flexible connectors.

Tankless water heater installation often needs a bigger gas line, because the line has to carry the combined demand of everything on it. For a new furnace, see our furnace installation page.

Before we leave, every appliance on the line is relit and running.

Gas line work is never a do-it-yourself project. A gas plumber sizes and pressure tests the piping so every appliance gets enough gas and nothing escapes.

If You Smell Gas, Leave First

Natural gas has a rotten-egg odor added so you can smell a leak. If you smell it, get everyone out of the house right away. Don't flip light switches, use a phone or light anything on the way out, and don't try to find the leak yourself.

Once you're outside and away from the house, call Spire or 911, and don't go back in until Spire says it's safe. After that, On Time Experts Heating, Air & Plumbing can find the source and make the repair. Spire's gas appliance safety tips also list signs to report, like a yellow or wavy burner flame.

Fix Leaks Where They Start

Gas piping can last decades, but fittings, valves and connectors can loosen or corrode, and that's where most leaks start. Some older homes still have uncoated brass connectors behind ranges and dryers. They can crack with age, so we replace them with new coated connectors when we find them.

What Happens During a Gas Line Repair and Installation Visit?

Here's how a typical job goes.

  1. Talk through the job. We ask what you need and look over the existing piping and appliances.
  2. Explain the plan. We explain the repair or the route for the new line, with upfront pricing before work starts.
  3. Do the work. We make the repair or run the new line, then add the shut-off valve and connector.
  4. Test and restore. We pressure test the line, restore gas and relight pilots.
  5. Finish up. Where a permit applies, we complete the required approvals, then clean up.

We walk you through what was done before we go.

Frequently asked questions

Yes, gas line installation can add a line for an outdoor grill, fire pit, patio heater or standby generator. The line is usually buried in a trench, so utilities are marked through Missouri One Call (811) before digging.

The gas connection is plumbing work, while the generator's electrical hookup is a separate job for an electrician.

Yes, a gas line for a stove should always be run by a qualified professional. Gas line installation for a range means tapping into the existing piping, sizing the new branch, adding a shut-off valve and pressure testing everything before the gas is turned on.

Missouri permits are set locally by the City, the county or your municipality, and most require one for new gas piping.

During gas line repair, plumbers find a leak by combining a pressure test with checks at each joint. A pressure test shows whether the system holds, and testing one section at a time narrows it down.

The plumber then checks fittings, valves and connectors with an electronic gas detector and a leak-detecting solution that bubbles where gas escapes. That section is repaired or replaced, and the line is tested again.

If you smell gas, get everyone out of the house right away, without flipping switches, using a phone or lighting anything, and call Spire or 911 once you're outside. Don't try to find the leak yourself.

Don't go back in until Spire says it's safe. After that, a qualified plumber can locate the leak, complete the gas line repair and pressure test the line before service is restored.

How Much Does Gas Line Repair and Installation Cost?

Gas line repair and installation cost depends on the length of the run and how many appliances it feeds.

Factors that can affect the cost include:

  • Run length and access: How far the line goes, and whether it passes through finished walls.
  • Appliance count: The number of appliances on the line.
  • Upsizing: Whether the line needs to be larger, or Spire needs to set a larger meter.
  • Outdoor work: Trenching for a grill, fire pit or generator line.

You'll get upfront pricing before any work begins.
