A gas smell detected anywhere near a range that isn't currently running, isn't being actively used for cooking, and has all its burners fully in the off position should never be treated as a minor issue that can simply be monitored casually over the following days to see whether it persists or goes away on its own. This is genuinely one of the few appliance-related situations covered anywhere on this site that carries real, immediate safety implications rather than being purely a matter of appliance performance, cooking quality, or repair convenience and cost.
This is Washington Gas's own guidance, and it is worth following exactly rather than improvising:
Washington Gas supplies the District of Columbia, Maryland and Virginia, so that line covers this whole service area. There is no charge for responding to a suspected leak, and no version of this where calling turns out to have been an overreaction.
Even a faint, intermittent gas odor — one that seems to come and go rather than being constant and overwhelming — can indicate a genuine small leak developing at a valve connection point, at a burner fitting somewhere within the range's gas delivery system, or along the supply line feeding gas into the unit from your home's main gas connection. It's genuinely important to understand that gas leaks don't reliably announce themselves through a strong, constant, unmistakable odor the way many people might assume based on general awareness of gas safety — a leak can very much be small, subtle, and easy to second-guess or dismiss as your imagination, while still representing a genuine and potentially serious safety hazard that needs to be taken seriously.
The instinct to wait and see whether it happens again is the dangerous part. A smell you noticed once and cannot reproduce is still worth a call, because the alternative is deciding by yourself that a gas leak was imagination.
It's genuinely important to understand and accept that this specific situation is not an appropriate one for homeowner troubleshooting, and it's actually not even an appropriate situation for most general appliance repair technicians to handle either, regardless of how experienced or skilled they might be with other types of appliance repairs. A suspected gas leak specifically requires either a licensed gas technician with specific training and certification in gas line work, or a call to your utility company's dedicated emergency response line, both of which have the proper training, equipment, and legal authorization to safely diagnose and address gas-related safety concerns.
We repair Wolf ranges, and we are telling you not to call us first. The utility comes out for this, and they come out free.
It's worth being explicit that you should never attempt to tighten gas connections yourself in an effort to stop a suspected leak, and you should never use plumbing sealants, tape, or compounds that aren't specifically rated and certified for use with gas line connections — improper attempted fixes using the wrong materials or techniques can very much make an existing small leak considerably worse rather than resolving it.
Ordinary PTFE tape is not gas-rated. Neither is most plumber's putty. A fitting that has been tightened by guesswork is harder for the next person to assess, not easier.
Once the immediate safety concern has been properly addressed by qualified professionals and the source of the leak has been definitively identified, a proper repair performed by a Wolf-certified technician can then address and fix the specific fitting, connection, or valve that was actually responsible for the leak in the first place.
That second stage is where an appliance specialist belongs — a burner valve, a manifold fitting or a connection inside the range, replaced with the correct part. It happens after the utility has declared the situation safe, never instead of calling them.
Natural gas has no smell of its own. Utilities add mercaptan, which most people describe as rotten eggs or sulphur. If you are smelling something like that near a range, treat it as gas rather than looking for another explanation.
Washington Gas's instruction is to leave immediately, not to ventilate first. Opening a window keeps you in the room and is not worth the time. Leave, then call from outside.
Only if it is genuinely on your way and you can reach it without moving the appliance or hunting for it. Pulling a range out to look for a valve while you can smell gas is exactly what the guidance means by not attempting to locate the source.
No, and this catches people out: a carbon monoxide detector does not detect natural gas. They are different hazards and need different devices. CO is odourless, which is the reverse problem — you cannot smell it at all.
A brief whiff at ignition, before the flame catches, is normal — that is unburnt gas reaching the spark. What is not normal is a smell with every burner off, or one that lingers after lighting. If a burner is failing to light promptly, see how Wolf's ignition system works.
If you can smell gas right now, stop reading and go outside. Call 911 and Washington Gas on 844-WASHGAS from a safe distance. Once the leak has been found and the situation declared safe, we repair the Wolf range itself — valves, fittings and burner components — throughout Arlington, Alexandria and the surrounding Northern Virginia communities, plus Washington, DC and Potomac, Maryland.
We serve Arlington, Crystal City, Rosslyn, Ballston, Pentagon City, Clarendon, and surrounding Northern Virginia communities.
