Gas companies only fix leaks on their side of the meter. Once utility crews confirm the street supply is safe and shut off the valve, everything past the meter belongs to the homeowner. That leaves you responsible for the lines running through your basement, walls, and crawl spaces. Harleys Plumbing, Heating, Cooling finds and repairs leaks from the meter outlet to your furnace, boiler, water heater, stove, dryer, and fireplace. We use digital testing equipment to verify whether a faint odor is an active leak and pinpoint the exact fitting that needs attention.
If you are searching for gas leak detection near me after the utility leaves, our phones are answered at any hour so you are never left waiting with the gas turned off. We service both natural gas lines and propane systems, handle the required town permits, and complete the pressure tests needed to get your fuel service restored safely.
Licensed, insured local technicians serving Marshfield and Plymouth County complete every gas connection we repair. When testing reveals a damaged run of pipe, we also provide gas line repair and installation.
Isn’t the Gas Company Responsible for Leaks in Marshfield, MA
The gas utility only owns the pipes up to your meter. When their crew responds to an odor call, they make the area safe. If the leak is inside your home, they turn off the meter and tell you to call a licensed professional.
Utility Side Versus House Side Piping
The utility owns the pipe from the street to the meter, along with the meter and regulator. Everything past the meter outlet belongs to you. This includes the black iron pipes, flexible lines, shutoff valves, and connectors behind your appliances. Propane systems work the same way: your gas supplier owns the tank, but the pipes inside your home belong to you.
When a Licensed Gas Fitter Is Required
In Massachusetts, only licensed plumbers or gas fitters can work on gas pipes under state code (248 CMR). Repairing a joint, running new pipe, or reconnecting an appliance requires a license and a town permit. Doing this work yourself is dangerous and can crack old fittings. A licensed pro can also provide the paperwork the utility needs before turning your gas back on.

Signs of a Gas Leak in Plymouth County Homes
Gas leaks are not always loud or obvious. A small leak at a valve can seep for weeks without anyone noticing, while a cracked line can release gas quickly. Look out for these common warning signs.
Rotten Egg or Sulfur Odor
Natural gas and propane have no smell on their own. Utilities add a chemical called mercaptan so people can smell leaks. It smells like rotten eggs or sulfur. A strong odor means you should leave your home right away. A faint smell that comes and goes often points to a slow leak at a fitting. Propane is heavier than air, so it pools near the basement floor before you smell it upstairs.
Hissing Near Appliances or Lines
A hissing sound near an appliance, valve, or pipe usually means gas is escaping under pressure. Worn connectors, loose nuts, or cracked pipe threads are common causes. Yellow flames instead of blue can also point to supply trouble. If you hear hissing, do not look for the source—leave the house immediately.
Dead Plants Over Buried Lines
Underground gas leaks push oxygen out of the dirt, which kills grass and plants directly above the pipe. A line of dead, brown grass across a green lawn often points to a leaking underground pipe feeding a garage, grill, or pool heater. We look for this during gas leak detection in Pembroke, MA, and across Marshfield.
What to Do if You Smell Gas on the South Shore
What you do in the first few minutes matters most. Safety comes first, and calling for repairs comes only after everyone is out of the house.
Leave the Home Immediately
Get everyone and every pet outside right away. Once you are in the yard or down the street, call 911 or the gas company. Never make the call from inside the house. Stay outside until emergency crews tell you it is safe. After the utility turns off the gas, call us to find and fix the leak.
Avoid Switches and Open Flames
A tiny spark can ignite gas in the air. Do not touch light switches, unplug cords, ring doorbells, or use indoor phones. Never light matches, lighters, or candles. Do not start a car in an attached garage. Just get outside into fresh air.
Gas Leak Detection Methods in the Greater Marshfield Area
Once the house is declared safe to enter, we test the pipes to find the leak. Natural gas leak detection in Marshfield, MA, uses three simple steps:
- Confirm: A pressure test shows if the pipes are losing gas.
- Narrow down: An electronic detector sniffs along the pipe to find where gas is thickest.
- Pinpoint: Bubbling soap solution shows the exact fitting that is leaking.
Electronic Gas Sniffers
Electronic gas sniffers detect gas long before a person can smell it. We move the wand along exposed pipes, valves, joints, and behind appliances. Gas moves with air currents, so a high reading might just mean gas gathered in a corner. We follow the readings back to the source. We use the same tool for propane leak detection on the South Shore, holding it close to the floor where propane tends to settle.
Pressure Drop Testing
To test pressure, we close appliance valves and attach a gauge to the pipes. If the gauge needle drops, gas is escaping somewhere in the line. By turning off one branch line at a time, we find out whether the leak is in the kitchen, near the heating system, or outside. This test works well for tiny leaks that sniffers miss.
Soap Solution at Fittings
Once we narrow down the location, we brush a special soap solution onto the fittings. Escaping gas makes bubbles appear right at the loose thread or leaking valve. We use this same test on new fittings after repairs to make sure they are completely tight.
Marshfield homes and families review an upfront price and approve the repair cost before any work begins. Our team also services fireplaces, so a lingering odor near the hearth can be evaluated during a gas log fireplace service visit.
Safe Gas Leak Repairs for Marshfield Hills and North Marshfield Homes
Finding the leak is only half the job. Every Marshfield gas leak repair must leave your pipes safe and code-compliant. Homes in Marshfield Hills and North Marshfield have different kinds of piping, from older black iron to newer flexible lines. Near Brant Rock and Green Harbor, salty ocean air also rusts exposed pipes faster.
Replacing Corroded Fittings
Rust weakens threaded iron fittings, valves, and joints until gas starts leaking out. In damp basements or crawl spaces, rust can eat through pipe walls from the outside. Instead of patching bad joints, we cut out the damaged section and install new, heavy-duty fittings with approved pipe sealant. If a pipe run is badly rusted, we replace the whole run.
Restoring Service to Code
After repairs, the pipes must pass a state pressure test before we can turn the gas back on. We coordinate with the gas utility, clear air from the lines, and relight the pilots on your boiler, furnace, and water heater. We check every burner flame and test every new joint for tightness before leaving.
