Every Gas Leak Detection in Woburn call includes the full inspection and testing process. Repairs are quoted separately once we know what we are dealing with, so you are never paying for work you did not approve.
We walk the entire gas system with a tracer gas leak detector, checking every fitting, valve, and appliance connection. This is how we confirm the leak is real and narrow down the general area before we start opening walls or digging.
We isolate sections of the line and run a pressure testing kit to confirm which segment is losing gas. The test takes 15 to 30 minutes and gives us a definitive answer, not a guess based on smell alone.
An electromagnetic pipe locator traces the gas line through walls, slabs, and underground so we know exactly where to dig or open. This saves you money on exploratory demolition and keeps the repair as small as possible.
You get a written summary of what we found, where the leak is, and what it will cost to fix. If the leak is on the utility side of the meter, we tell you that too, so you are not paying for a repair that is not yours.
Once we know the source, we quote the repair before we touch anything. Fitting repairs, short pipe runs, and appliance connections are priced on the spot. Underground and slab leaks get a written quote based on access and pipe length.
Gas Leak Detection in Woburn is the process of finding where natural gas or propane is escaping from a pipe, fitting, appliance connection, or underground line before it becomes a fire or health hazard. Our techs start with a tracer gas leak detector and an ultrasonic leak detector to confirm the presence of gas, then use a pressure testing kit to isolate the leaking section. We inspect copper pipe, PEX tubing, and PVC pipe runs, check solder fittings and pipe sealant joints, and map the line with an electromagnetic pipe locator so we know exactly what we are dealing with before we open a wall or dig.
Woburn's older housing stock means a lot of original gas piping is still in service, and decades of ground movement plus freeze-thaw cycles each winter work those joints loose. When you call for gas leak repair near me Woburn, you get a tech who has seen this exact pattern in neighborhoods across Middlesex County. If you need gas leak detection Woburn MA near me after hours, we run emergency calls 24/7 so a suspected leak never waits until morning.

Sewerin Tracer Gas Detector
Confirms the presence of gas and narrows the leak to a general area before we start opening walls or digging.
Gutermann Ultrasonic Leak Detector
Listens for the high-frequency sound of gas escaping from a pinhole or crack, pinpointing the exact source.
Fluke Thermal Imaging Camera
Spots temperature anomalies around joints and pipe runs that indicate a leak or a failing connection.
Electromagnetic Pipe Locator
Traces the gas line through walls, slabs, and underground so we know exactly where to dig or open.
RIDGID Video Pipe Inspection Camera
Lets us see inside pipe runs behind walls and under slabs without tearing out the whole section.
Pressure Testing Kit
Isolates sections of the gas line and confirms which segment is losing pressure, giving us a definitive answer.
General Pipe Cleaners Inspection Camera
Second camera option for tight or awkward pipe runs where the RIDGID unit will not fit.
Tracer Gas Detection
We introduce a small amount of tracer gas into the line and use a Sewerin detector to follow it to the escape point. This works on underground lines and behind walls where a visual inspection would not find anything.
Pressure Isolation Testing
We close off sections of the gas system and pressurize each one individually. The section that loses pressure is the one with the leak. This takes 15 to 30 minutes and gives us a definitive answer before we start any repair work.
Acoustic Leak Detection
Using an acoustic leak detection microphone and an ultrasonic leak detector, we listen for the sound of gas escaping. This is especially useful for pinhole leaks in copper pipe that are too small to smell but still dangerous.
Code-Correct Repair Standards
Every repair follows Massachusetts plumbing code. We use gas-rated pipe sealant, proper solder fittings, and materials rated for gas service. After the repair, we pressure test the line again and document the reading before we leave.
01
What we do: This is the most common call we get in October and November. The furnace fires up, the gas line pressurizes, and a fitting that was fine all summer starts leaking. We inspect the furnace connection, the supply line, and the shutoff valve with a tracer gas detector and pressure test the system.
→ Most of these are a failed fitting or a loose union. We replace it, pressure test the line, and you have heat back the same day.
02
What we do: We treat rental calls as priority. We inspect the unit, document what we find with photos and a written report, and repair the leak if it is on the property side of the meter. If it is on the utility side, we tell you so you can call the gas company.
→ You get a documented inspection and repair, which protects you as a landlord and gets your tenant back to normal fast.
03
What we do: We run a full gas leak inspection on the property, including the meter, all appliance connections, and any visible pipe runs. We pressure test the system and give you a written report you can use in negotiations.
→ You know exactly what you are buying. If there is a leak, you have a repair quote in hand before you sign.
04
What we do: We pressure test the system to find the leaking segment. This is often an underground line or a slab leak that has been quietly losing gas for weeks. We locate it with an electromagnetic pipe locator and repair the failed section.
→ Your bill goes back to normal, and you stop paying for gas that never made it to your appliances.
Woburn's housing stock ranges from 1920s copper pipe runs near Woburn Square to newer PEX tubing installs out toward Burlington. The older homes are where we find most gas leaks, because decades of freeze-thaw cycles work those original solder fittings loose. Each winter, we get a wave of calls after the first hard freeze, when the ground shifts and pipes that were fine all summer start leaking. We also see underground main line leaks in the Four Corners area, where older service lines have been in the ground for 50-plus years. Our techs know the difference between a fitting leak and a slab leak, and we carry the tools to handle both. If you need 24/7 gas leak repair Woburn MA, we answer the phone and we show up. We serve all of Woburn, including ZIP codes 01801, 01815, and 01888, plus Stoneham and Burlington.
Woburn Square
Older housing stock with original copper pipe runs. We see a lot of failed solder fittings here, especially after winter.
Four Corners
Mid-century homes with underground gas service lines that are reaching the end of their useful life. Underground main line leaks are common here.
Downtown Woburn
A mix of older commercial buildings and residential units. We handle gas leak detection for both, including restaurant kitchen lines.
Horn Pond Area
Homes near the pond deal with higher soil moisture, which accelerates pipe corrosion on underground lines.
Freeze-thaw cycles each winter
Ground movement works pipe joints loose and causes pinhole leaks in copper pipe. We see a spike in calls from December through March.
Older housing stock with original gas piping
Many Woburn homes still have the original gas lines from the 1920s to 1950s. These are more prone to corrosion and fitting failures than newer PEX tubing.
High water table near Horn Pond
Moisture in the soil accelerates corrosion on underground gas lines, leading to more main line leaks in that area.
These are the calls we get most often from Woburn homeowners and property managers. If any of these sound familiar, do not wait.
Problem
A failed fitting or cracked connection at the appliance can leak gas into the basement or utility closet. Even a small leak builds up over time and becomes a real explosion risk.
Our Fix
We inspect the appliance connection, the shutoff valve, and the supply line with a tracer gas detector. Most of these turn out to be a failed solder fitting or a loose union that we can replace in two to three hours.
Problem
A hissing sound usually means gas is escaping under pressure from a pinhole or crack in the pipe. This is often a sign of pipe corrosion or a joint that has worked loose from ground movement.
Our Fix
We use an ultrasonic leak detector to hear the exact escape point, then a video pipe inspection camera if the line runs behind a wall. We open the smallest section possible, replace the failed pipe, and pressure test before closing it up.
Problem
An underground main line leak can go unnoticed for months. Dead grass in a strip, a persistent wet spot, or a gas smell in the yard all point to a buried line failure that needs immediate attention.
Our Fix
We trace the line with an electromagnetic pipe locator, confirm the leak with a tracer gas detector, and excavate only where we need to. Most underground repairs are done in one day with a small trench rather than a full yard dig.
Problem
If your gas usage has not changed but the bill jumped, a leak somewhere in the system is the likely cause. Ignoring it means paying for gas you are not using and risking a bigger problem down the road.
Our Fix
We run a full pressure test on the system to find the leaking segment. This is one of the most common calls we get in Woburn after the first cold snap, when heating systems start running hard and small leaks become obvious.
A gas leak is not a wait-and-see problem. Here is what you get when you book Gas Leak Detection in Woburn with our team.
Fast Source Pinpointing

Called about a gas smell near the water heater. Tech arrived in about an hour, found a loose union, tightened it, and pressure tested the line. Charged exactly what he quoted. No upsell, no drama. Would call again.
Yelp ★★★★★4.8
We had an underground gas leak in the front yard. Two other companies wanted to dig up the whole yard. These guys traced it with a locator and only dug a small trench. Saved us thousands. Highly recommend.
BBB ★★★★★4.9
Professional from start to finish. They explained what they were doing, showed me the pressure test reading, and cleaned up after themselves. The gas smell was gone and the bill went back to normal.
Google ★★★★★5.0
Emergency call on a Sunday night. They answered, dispatched a tech, and had the leak repaired by midnight. I did not think that was possible. Fair after-hours rate and a written report for my records.

Real answers to the questions we hear most often from local homeowners and property managers.
A slab leak and a gas leak can both show up as unexplained moisture or a spike in your utility bill. We use acoustic leak detection microphones and thermal imaging to find leaks under concrete slabs in Woburn homes without tearing up the whole floor.
View Slab Leak DetectionUnderground gas and water main lines in Woburn take a beating from freeze-thaw cycles. We use electromagnetic pipe locators and tracer gas detectors to find the break, then repair or replace the failed section with minimal digging.
View Underground Main Line Leak DetectionIf you smell gas near a wall or see staining on a ceiling, the leak could be in a pipe run behind the drywall. We use video pipe inspection cameras and moisture meters to find it without opening the whole wall.
View Wall And Ceiling Leak DetectionA gas water heater with a failing connection or a cracked tank can leak both water and gas. We inspect the gas supply line, the shutoff valve, and the tank itself, then repair or recommend replacement based on what we find.
