A Highlands Ranch water heater that stops heating or drips usually has one failed component, such as an element, thermostat, igniter, thermocouple or valve, and a plumber can often replace it on the first visit. A tank leaking from the shell needs to be replaced. Call the number on this page to be connected with a local plumber in Highlands Ranch.

What happens when you call
Your call is connected to an independent plumber who works in Highlands Ranch. They'll ask about the fuel type, the heater's age and what you are noticing. On site, the plumber checks gas or power, tests elements and thermostats or the burner and pilot assembly, inspects the relief and drain valves, and looks for leaks and corrosion at the fittings. You'll get an explanation of what failed and whether it is worth repairing before any work starts.
What affects the cost
- The failed part. Elements and thermocouples are small parts; a gas control valve or power-vent blower costs more.
- Installation location. Basement mechanical rooms are easier to work in than finished-basement closets.
- Related fixes. A stuck drain valve, missing expansion tank or corroded shutoff can add time.
- Replacement. A failed tank becomes a replacement with a Douglas County permit.
Local conditions in Highlands Ranch
Highlands Ranch is a master-planned community built from the 1980s onward, and the largest community in Douglas County. That timeline means most homes are on their second or third water heater by now, and plenty of replacements from the 2000s and 2010s are themselves getting older. Heaters are commonly in basements, often next to the furnace.
Highlands Ranch Water provides water and wastewater for the whole community. Its supply is mostly surface water from the South Platte River, Plum Creek and Dad Clark Gulch, stored in local reservoirs and treated at the Joseph B. Blake plant, with wells mainly as backup. It uses chloramine in the distribution system, and its report does not list a hardness value, so sediment is something a plumber checks by draining the tank. The district maintains the line through the curb stop, and the homeowner owns it from there into the house, heater included. During a private plumbing emergency, Highlands Ranch Water will help shut off water at the curb stop.
Because Highlands Ranch is unincorporated, permits come from the Douglas County Building Division, whose Plumbing/Mechanical permit application lists water heaters, gas or electric. We could not confirm the gas utility from an official page, so check your bill. If you smell gas, leave the house first, then call 911 and your gas utility from outside.
Before the plumber arrives
- Clear a path to the heater and furnace area
- Shut off the heater and its cold supply if it is leaking
- Find the date on the rating label
- Know where your main shutoff is
