Gas Line Repair

A gas leak is a fire and explosion risk, so the first call is never to a plumber — it’s to 911 or the gas utility, from outside. Once the area is safe, we repair leaking piping, valves and appliance connectors, pressure-test the system, and run new gas lines for ranges, dryers, water heaters and boilers.

At your location in 60 minutes or you save $60.

The short answer

If you smell gas, get everyone out now. Don’t flip light switches, use your phone or start appliances inside, and don’t light anything. Once you’re outside and away from the building, call 911 or your gas company. When the area is safe, call us: we find the leak, repair the piping or connector, and pressure-test the line, which has to pass before gas that was shut off can be turned back on.

Is this an emergency?

Call now if…

  • You smell gas — get out first, then call 911 or the gas utility from outside
  • A carbon monoxide alarm is sounding — get everyone out and call 911
  • You hear gas hissing from a pipe or connector — leave and call from outside
  • Your gas is off and you have no heat or hot water in freezing weather

Can usually wait for a scheduled visit

  • A gas line for a new range, dryer or water heater
  • Replacing an old connector that isn’t leaking
  • Non-urgent items from a gas piping inspection

Not sure? Call anyway — we’ll tell you honestly.

Do this right now

  1. If you smell gas, get everyone out of the building right away.

Signs you need us

  • A rotten-egg smell near the stove, dryer, boiler or meter
  • A hiss near a gas pipe, valve or appliance
  • Gas shut off by the utility after a leak
  • An old, kinked or uncoated brass connector behind an appliance
  • Rust or corrosion on gas piping or around the meter
  • A gas bill that climbs for no clear reason
  • Dead grass or plants along the gas line to a house
  • A gas piping inspection that flagged repairs

How we handle the call

  1. 01

    After it’s safe

    We come in once the utility or fire department has made the area safe — a plumber should never be the first call for a gas smell.

  2. 02

    Find the source

    We check joints, valves and appliance connectors with leak-detection solution, working along the piping until we find the leak.

  3. 03

    Repair it properly

    Leaking fittings, valves and sections of pipe are replaced, and old connectors swapped for new ones the right size for the appliance.

  4. 04

    Pressure-test the system

    The repaired piping is tested under pressure. Gas that the utility shut off for a leak stays off until the repair is done and the piping passes a test.

  5. 05

    Straight advice

    If the piping is old, corroded or too small for what you want to add, we explain why and price the replacement before any work.

Know your building

Gas piping in apartment buildings, houses and restaurants

In an apartment building, a gas shut-off at the service can leave every kitchen in the building without cooking gas until the repair is done. When the gas company shuts off gas for a leak, it stays off until the problem is repaired and the piping passes a pressure test, and some gas work also needs a permit and an inspection. Co-ops and condos often add house rules on contractors and work hours, so we work with the super, building manager or board on access and timing. We explain upfront what your repair involves and what has to happen before the gas can come back.

In a detached house or an older rowhouse, the gas piping often runs from the meter through the basement or crawlspace to each appliance, and old uncoated brass connectors behind ranges and dryers are a common weak point. Restaurants and commercial kitchens run several high-demand appliances on one system, so adding a range or fryer can outgrow the existing pipe, and the flexible connectors on equipment that’s rolled out for cleaning need regular checks. Some cities also require periodic gas piping inspections for larger buildings, and those inspections can turn up corroded pipe, leaking fittings or worn valves that need repair. Many states and cities require carbon monoxide alarms in homes as well — any time gas appliances are worked on is a good time to test yours.

Upfront price, every time

What gas line repair costs

A leaking connector or a fitting at an exposed appliance valve is a short repair. The price goes up when the leak is in piping inside a wall or ceiling, when a long or corroded run has to be replaced, or when a building’s whole system has to be repaired and tested after a utility shut-off.

Some gas work needs a permit, which adds paperwork and time, and we tell you on site whether yours does. New lines are priced by length, pipe size and route — a short dryer line in an open basement takes far less work than a new run up through finished floors to a kitchen. Either way, you have the price before we start.

Honest advice

Fix the fitting, or replace the gas piping?

When one fitting, valve or connector is leaking on otherwise sound pipe, replacing that part is the repair, and a pressure test afterward shows whether the rest of the system is tight.

Replacing the piping makes more sense when it’s badly corroded, when leaks keep turning up along the same run, or when you’re adding a high-demand appliance — a bigger range, a tankless water heater, a commercial kitchen line — that the existing pipe is too small to feed. An undersized line starves the appliances on it, so burners and heaters don’t run as they should. We size what you have against what you want to run and price both options.

Mistakes that make it worse

  • Hunting for the leak with a match, lighter or light switch — any flame or spark can ignite it
  • Brushing off a faint smell because it comes and goes — leave and call the utility from outside anyway
  • Turning the gas back on yourself after the utility shut it off — it stays off until the repair passes a test
  • Reusing an old flexible connector when an appliance is moved or replaced

Keep it from happening again

  • Keep working carbon monoxide alarms near bedrooms — many states and cities require them in homes — and test them monthly
  • Make sure everyone at home knows the rotten-egg smell, and knows to get out before calling
  • Have gas appliances serviced regularly, with their connectors checked at the same time
  • Building owners: if your building needs periodic gas piping inspections, know when the next one is due and book it early

FAQ

Gas Line Repair questions

I smell gas. Should I call you first?

No. Get everyone out, then call 911 or your gas utility from outside. Call us once the area is safe, and we’ll find and repair the leak.

The utility shut off our gas. How do we get it back?

The leak has to be repaired and the piping has to pass a test before the utility turns the gas back on, and some repairs also need a permit. We do the repair and the pressure test, and tell you upfront what else your job involves.

Can you run a gas line for a new stove or dryer?

Yes. We check that the existing piping can feed the new appliance, run the line with a shut-off valve at the appliance, connect it and test it for leaks.

Does my building need a gas piping inspection?

It depends on where it is. Some cities require periodic gas piping inspections for larger buildings, and your local building department can tell you whether yours is covered and when it’s due. If an inspection turns up problems, we repair them and pressure-test the piping.

Do I need a carbon monoxide alarm?

Yes, if your home has any gas appliances — and many states and cities require carbon monoxide alarms in homes. A gas appliance that isn’t burning or venting properly can produce carbon monoxide, which you can’t see or smell.

Can I hook up a gas stove or dryer myself?

We don’t recommend it. A gas connection needs the right fittings, a shut-off valve and a leak test afterward — it isn’t a DIY job.
