In Evergreen, a water heater should be replaced when the tank leaks, the hot water turns rusty or scarce, or an older unit keeps failing. Evergreen is unincorporated, so Jefferson County Building Safety issues the plumbing permit for water heaters. Call the number on this page to be connected with a local plumber in Evergreen.

How the call works
The number connects you with an independent plumber who covers Evergreen. Mountain homes vary a lot, so expect questions about fuel (natural gas, propane or electric), tank size, where the heater sits and whether the house is on district water or a private well. A visit lets the plumber check venting, combustion air and the water supply before pricing a replacement. If water is leaking, close the cold valve on top and shut off the fuel or breaker.
What drives the cost
- Fuel type and whether the new unit must be rated for propane
- Capacity and efficiency, or a tankless conversion
- Venting changes, which can be more involved in mountain homes
- Expansion tank, drain pan and relief line work
- Access down narrow stairs or into crawl spaces
- The county permit and hauling the old tank down the hill
Local conditions in Evergreen
Inside its boundaries, Evergreen Metropolitan District treats water from Evergreen Lake with membrane filtration and chlorine. The district describes its water as only slightly hard, typically about 30 mg/L, and says a softener isn't needed. It also adds a corrosion-control treatment. Outside the district, Jefferson County says mountain-area homes are generally supplied by private wells, and well water can be harder or carry iron or manganese that build up in a tank. If you're on a well and your fixtures show staining or crust, testing the water before choosing a heater is worth it.
Jefferson County Building Safety handles permits for unincorporated areas, including plumbing permits for water heaters, through its online portal; call 303-271-8260. The gas utility isn't confirmed on an official page for Evergreen, and some homes use propane. If you smell gas, leave the house first, then call 911 and your gas utility or propane supplier from outside.
For a burst line or sewer backup on district service, the district asks customers to shut off water at the home's valve and call both a plumber and the district at 303-674-4112, option 2, or option 9 after hours.
