Water heater replacement
A leaking tank or a heater past about 10 years old is usually replaced rather than repaired. A proper Colorado install includes a permit, correct venting for altitude, an expansion tank where required, a drip leg on the gas line and a relief valve discharge pipe.

About water heater replacement
Most replacements are like-for-like: same fuel, same size, same spot. It's also the moment to check whether the old install was correct, because venting, gas line and expansion tank problems are common in older basements.
Water heater replacement requires a permit in most Front Range jurisdictions. The plumber pulls it, and an inspector checks the venting and gas connections.

Water heater repair
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.

A tankless water heater heats water as it flows, so it doesn't run out, but it needs a larger gas line, its own venting and a unit rated for your elevation.

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.
