If you smell gas in a Northglenn home, leave first, then call 911 and your gas utility from outside; the utility and its emergency number are on your gas bill. Gas line work and water heater swaps need a plumber and a city permit, so call the number on this page to be connected with a local plumber in Northglenn.

Do gas lines need a permit in Northglenn?
Yes. The City of Northglenn Building Division, whose services are provided by SAFEbuilt, lists gas lines among the work that requires a permit, along with water heater installation or replacement, plumbing modifications and outside water or sewer line repairs. The Building Division can be reached at 303.450.8745, and inspections are requested at 303.450.8748. A plumber who works regularly in Northglenn will know the process and usually handles the paperwork.
What should owners of Northglenn's original homes expect?
Northglenn began in 1959 as Perl-Mack's planned community, which Life magazine called the most perfectly planned community in America, and much of its housing dates from the late 1950s and 1960s. Gas piping in those homes has typically been through decades of furnace and water heater replacements and kitchen updates. It is common to find iron pipe tapped at several points, capped stubs where old appliances were, and connectors that are well past their prime. Before adding an appliance, a pressure test tells the plumber whether the existing system is sound. Newer infill such as Karl's Farm is a different story, with modern piping.
Which gas utility serves Northglenn?
That was not confirmed from an official source. The city's energy incentives page promotes Xcel Energy rebate programs, but no page reviewed stated the gas provider outright, so check your gas bill. It names the utility and lists the emergency number. Save that number somewhere you can reach from outside the house.
A local note
Northglenn sits along I-25 around 120th Avenue and Washington Street, near Webster Lake and the RTD N Line station. With so many homes from the same era, neighbors often face the same gas piping issues at the same time. Plan non-urgent work for late summer, ahead of steady furnace use.
If you are remodeling a kitchen or finishing a basement in an original Northglenn home, that is the best time to deal with old gas piping, while walls and ceilings are open. Replacing a section of tired pipe or rerouting a branch costs less then than after the drywall goes up. Ask the plumber to cap any dead branches back at the main, and to replace old range and dryer connectors while they are on site.
