Gas Leak Detection

THE SHORT ANSWER
If you smell gas, do not flip a switch or light anything. Get everyone out and call your gas utility first so they can shut it off at the meter. After that, Hargrave’s finds the leak with electronic detection and a pressure test, shows you where it is, and repairs the line to Louisiana code. Small leaks are also real: a pilot that keeps going out or a bill that climbed can be the only sign.

How urgent is what you are smelling?

Gas triage, in order

Gas is the one thing where the first step is not calling a plumber. Find your situation and do that step first.
Strong smell, hissing, or anyone feeling sick
A clear gas odor indoors, an audible hiss, or headaches, nausea or dizziness that improve when you step outside.
Leave immediately without touching switches, get everyone out and away, and call 911 or your gas utility to shut it off. Call us after it is safe and we will find and repair the line.
Right now, 24/7
Faint smell that comes and goes
An occasional odor near an appliance, the meter or a wall, with nothing obvious to see.
Ventilate, leave the appliance off and call us the same day. Electronic detection and a pressure test will confirm whether there is a leak and where.
Today
No smell, but the signs are there
Pilot lights that will not stay lit, a yellow flame, soot marks, or a gas bill that climbed with no change in use.
Book it. We test the system under pressure so you get a yes or no instead of a guess, and we check the appliance connections.
Schedule now
CSST with no lightning bonding
Flexible corrugated stainless tubing in a newer home, and nobody can tell you whether it was bonded.
Worth checking in a lightning-heavy place like Acadiana. We inspect and test it, and we can add the correction.

Why gas leaks happen here

Lightning and CSST
Corrugated stainless tubing that was never bonded can take an arc from a nearby strike and end up with a pinhole. Acadiana gets plenty of lightning, so this is not a theoretical risk.
Wet ground on buried line
Soil that stays saturated corrodes buried steel from the outside. The first sign is often a dead patch of grass rather than a smell.
Load added over the years
A generator, an outdoor kitchen or a tankless heater added to an old system stresses joints that were fine at the original load.

How a gas leak call goes

  1. Safety first
    If you smell gas, leave and call your gas utility to shut it off. Then call our emergency line, answered 24/7.
  2. We test the system
    Electronic detection at the connections and a pressure test on the piping, so the answer is measured rather than sniffed.
  3. We show you the leak
    You see where it is and what caused it, then the repair is priced in person before we start.
  4. Repaired, retested, relit
    Line repaired, whole system pressure tested again, appliances relit and checked before we leave.

Watch: how it works on a real job

24/7 EMERGENCY SERVICE

Gas smell at 2am: leave the house, call the utility, then call us.

Life safety comes first and we will say so on the phone. Once the gas is off, our emergency line is answered 24/7 and we will handle the detection and the repair.

Gas leak questions we get every week in Lafayette and Youngsville

What should I do the moment I smell gas?
Leave. Do not turn lights or switches on or off, do not light anything, and do not go looking for it. Get everyone out and call 911 or your gas utility so it can be shut off at the meter. Then call us for the line.
Can you find a leak I cannot smell?
Yes. Electronic detection picks up concentrations well below what a nose registers, and a pressure test on the piping gives a yes or no on the whole system rather than one joint at a time.
How do you know the repair worked?
We pressure test the entire system again after the repair, not just the section we touched, then relight and check every appliance with you before we leave.
Is a yellow flame a problem?
It is worth a look. A burner should burn blue. Yellow can mean poor combustion or a supply issue, and poor combustion is how carbon monoxide gets made. If you have a CO alarm sounding, leave and call 911.
