Gas Line Repair in Castle Rock, CO
Castle Rock is a mains gas town — 78% 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. 78% of homes in Castle Rock 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 Castle Rock 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.

What B25040 measures is the heating fuel, not the connection. It is the closest published proxy for whether there is a buried service line here, and it is a proxy. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Colorado as a whole, 68% of households are on mains gas and 3% on tank propane. Castle Rock sits 9 points above the state on mains and 1 point below it on propane. That is the gap a statewide number papers over, and the reason the figures above are this town’s rather than the state’s.
Before anyone digs on the property
8-1-1 is free and nationwide, and PHMSA gives callers a 99 percent chance of avoiding an incident, injury or worse. Ask them what they will and will not mark: privately owned buried lines on your own side of the meter frequently are not covered.

What to ask whoever quotes it
Ask how much gas work they actually do, not whether they can. Gas is separately licensed in most jurisdictions and plenty of capable plumbers do very little of it.

Checking a plumber in Colorado
Colorado licenses are issued by the Colorado State Plumbing Board, Division of Professions and Occupations, 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. Gas is one part of what Castle Rock calls us about.
