In Larkspur, a water heater needs replacing once the tank leaks, the hot water fades or turns rusty, or repairs keep coming on an older unit. Inside town limits, building permits go through the Town of Larkspur, not Douglas County, with SAFEbuilt doing inspections. Call the number on this page to be connected with a local plumber in Larkspur.

When you call
The number connects you with an independent plumber who works in southern Douglas County. They'll ask about the heater's fuel, size, age and location and whether it's leaking. On site, they'll check the vent, gas or electric supply, shutoffs and clearance before quoting. If there's water on the floor, close the cold valve above the heater and shut off its gas or breaker.
What drives the price
- Tank size, fuel and efficiency, or a move to tankless
- Vent and gas connector updates
- Expansion tank, drain pan and relief line work
- Where the heater sits and how easy it is to reach
- The Town permit, inspection and haul-away
Larkspur conditions
The Town's Public Works Department runs water and wastewater within town limits, with the water system operated under contract by Semocor. The supply is groundwater from three wells in the Denver and Arapahoe aquifers rather than surface water. No hardness figure appears in the sheet we used, but well water often carries minerals that settle in a tank, so look at what drains out of the old heater and plan on annual flushing if there's a lot of sediment. Areas of the 80118 ZIP outside town limits aren't on the Town system.
Water emergencies inside town limits go to Town Hall during business hours and to Semocor after hours. Building permits for town addresses are processed by the Town Building Department at 8720 Spruce Mountain Road, (303) 681-2324, with SAFEbuilt inspections scheduled at 720-641-1956. The page doesn't mention plumbing permits specifically, so the plumber should confirm what a heater swap requires. Addresses outside town limits go to Douglas County.
Black Hills Energy supplies gas. If you smell gas, leave the house first, then call 911 and Black Hills using the number on your bill.
Checklist before the visit
- Confirm whether you're inside town limits
- Photograph the heater's label for size, fuel and age
- Clear space around the heater and its vent
- Find the main water shutoff
- Note any past leaks, noises or relief valve drips
- Decide whether you want a tankless price as well
Getting these details together before the visit helps the plumber quote accurately and keeps the replacement and SAFEbuilt inspection on a predictable schedule.
