Gas Line Repair in Mukilteo, WA
Mukilteo is a mains gas town — 57% of households heat with utility gas. The useful thing to know before anything goes wrong is where the utility’s responsibility stops.
Read this first
Responsibility changes hands at the meter outlet. The line under the ground between the street and the meter is the utility's up to that point, and the yard line and house piping after it are the property owner's. 57% of homes in Mukilteo heat with utility gas.

If you smell gas right now
Leave the building on foot. Do not use a phone or a light switch inside. Call 911 and your gas utility from somewhere else, and do not call us — we are a referral service, not an emergency line. The full list, in order.
How Mukilteo is supplied
Under 49 CFR § 192.3, a service line ends at "the outlet of the customer meter or at the connection to a customer’s piping, whichever is further downstream". Upstream of the meter is the operator’s regulated line. Downstream is customer piping, under local code.
That is where the regulated line stops. Who pays is a separate question set by tariff and state regulation, and it is worth asking your utility rather than assuming.

B25040 is a fuel count, not an infrastructure count. It tells you what burns in these houses, from which the arrangement follows — but it is an inference, not a meter reading. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Washington as a whole, 39% of households are on mains gas and 2% on tank propane. Mukilteo sits 18 points above the state on mains and about level with it on propane. A state figure would flatten exactly that difference, which is the reason these pages are built town by town instead.
Before anyone digs on the property
The single most dangerous thing most people will ever do to a gas line is put a spade through it. PHMSA calls excavation damage the leading cause of pipeline incidents; 8-1-1 is a nationwide toll-free number to call before any excavation, and calling it gives a 99 percent chance of avoiding an incident.

What to ask whoever quotes it
Ask what is being left behind: where the new pipe runs, at what depth, and whether you will get a photograph of the trench before it is filled. That record will not exist anywhere else and you will want it eventually.

Checking a plumber in Washington
Washington licenses are issued by the Washington State Department of Labor and Industries, which publishes a public search you can use before work begins.
Gas work is separately permitted and separately licensed in most jurisdictions, so ask specifically about gas rather than plumbing in general.
For repair work, not for a suspected leak.If you can smell gas, leave and call 911 or your utility from outside; this is the wrong number for that. For everything else — a line, a meter, an appliance connection — we will route you to a contractor covering your area, free of charge to you. Other Mukilteo requests are covered by the same line.
