Gas Line Repair in Mountlake Terrace, WA
In Mountlake Terrace, both arrangements are common — 31% on utility gas, 2% on tank propane. Which one you have decides whether any of your installation belongs to somebody else.
Read this first
Mountlake Terrace splits between mains and tank gas, at 31% on utility gas and 2% on bottled. Which one a property has decides where responsibility changes hands: a meter outlet marks the boundary on mains gas, while a tank puts the whole installation on the owner.

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 Mountlake Terrace is supplied
In a town with both, the useful page is the one about the arrangement you actually have. The meter is the tell: if there is one, there is a service line behind it and a boundary at its outlet.

B25040 records what heats the house, which is the best available guide to whether a property has mains gas or a tank — it does not count service lines directly. 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. Mountlake Terrace sits 8 points below 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
Before any digging — a fence post as much as a foundation — call 8-1-1. It is a nationwide toll-free number, it costs nothing, and PHMSA puts the chance of avoiding an incident afterwards at 99 percent.

What to ask whoever quotes it
Ask them to describe the fault before they price it. "The line needs replacing" is not a diagnosis, and on a buried run the difference between one damaged point and a line at the end of its life is most of the cost.

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. We serve Mountlake Terrace for plumbing that has nothing to do with gas.
