Water heater repair in Golden, CO
If a gas water heater has no hot water, the pilot, thermocouple or gas valve is the usual cause; on an electric heater it's usually an element or thermostat. Those parts are repairable. A tank that leaks from the bottom can't be repaired and needs to be replaced.

Water heater repair for Golden homes
Most U.S. homes have a 40 or 50 gallon gas or electric tank in a basement, garage, attic or utility closet. Gas appliances need correct sizing and venting (and altitude adjustment in mountain states), and a heater that was installed without the right adjustments can soot up, trip its safety switch or struggle to keep up.
For the full guide, including what you can safely do before a plumber arrives, see water heater repair explained.

Water heater repair in Golden: what's different
Golden's colder canyon water makes water heaters work harder, and older homes near downtown have heaters in tight basement spaces with older venting. Common repairs are thermocouples, igniters, gas valves and electric elements.
Homes on wells up the canyon may have sediment or hardness issues that clog tanks and shorten their life. A plumber diagnoses the problem and tells you whether repair or replacement makes more sense for the heater's age.

Other Golden conditions that affect plumbing
- Canyon cold and wind: Cold air drains out of Clear Creek Canyon at night, and wind pulls heat from exterior walls. Pipes in north- and west-facing walls freeze more often here than in the city.
- Wells and septic up the canyon: Mountain properties may have well pumps, pressure tanks and septic systems. A plumber who works on those systems is a different call from a city-water household.
- Older pipes near downtown: Homes from the early 1900s near downtown may still have galvanized supply and clay sewer lines that need a camera inspection before major work.

No hot water? What to check first
On a gas water heater, check that the pilot is lit and the gas valve is on. On an electric heater, check the breaker and the high-limit reset button. If the pilot won't stay lit, the breaker trips again, or you smell gas, stop and call a plumber.
Costs & planning
Repair or replace your water heater?
Repair when a replaceable part failed on a heater under about 8 years old. Replace when the tank itself leaks, the heater is past 10 to 12 years, or repairs keep adding up. A leaking tank can't be repaired.
