If you smell gas, leave the building right away, then call 911 and Xcel Energy at 1-800-895-2999 from a safe distance. For gas piping beyond the meter, such as repairs, a line for a new range or dryer, or a backyard grill hookup, call the number on this page to be connected with a local plumber in Denver.

Smell gas? Do this first
- Get everyone outside. Do not stop to search for the leak or open windows.
- Leave switches alone. Do not flip lights, start a car in an attached garage, or use anything that could spark.
- Call from a safe distance. Once you are well away from the house, call 911 and Xcel Energy's gas emergency line at 1-800-895-2999.
- Wait for the all-clear. Do not go back inside until emergency responders or the utility say it is safe.
Xcel Energy serves gas in the City and County of Denver. If you live outside the city and are unsure of your provider, check the name on your gas bill.
Utility side versus your side
The gas utility handles its mains, the service to your meter and the meter itself. The piping downstream of the meter, through the house to the furnace, water heater, range, dryer and fireplace, is generally the owner's to maintain, and that is where a plumber comes in.
Gas work a plumber handles
- Running a new line for a gas range, dryer, fireplace insert or patio heater
- Extending gas to a backyard grill, fire pit or detached garage heater
- Locating and repairing a leak in house piping after the utility has made things safe
- Pressure-testing lines after a remodel or before reconnecting an appliance
- Replacing old flexible connectors and installing shutoff valves at appliances
- Sizing piping when you add a high-demand appliance such as a tankless water heater
Before anyone digs
Outdoor lines to a grill or outbuilding usually mean trenching. Colorado 811 says to contact it before any digging, and the service is free, but it only marks public utility lines. Private lines, including a gas line to a grill, are not marked, so tell the plumber about anything already buried on the property.
Permits and cost
Ask the plumber whether your gas work needs a permit and inspection from Denver Community Planning and Development, and who will apply for it. Cost depends on the length of the run, how many walls or floors it passes through, whether existing pipe is large enough for the new load and whether trenching is involved.
