Frederick homeowners typically replace a water heater when the tank leaks, the hot water fades or turns rusty, or an aging unit needs frequent repairs. The Town of Frederick Building Department handles permits and inspections and verifies the plumber on jobs that require one. Call the number on this page to be connected with a local plumber in Frederick.

Is it time for a new heater?
- A leak from the tank body or a wet spot that keeps coming back
- Hot water that's discolored while the cold runs clear
- Popping and rumbling that get louder each month
- Hot water that gives out sooner than it did a year ago
- Rust on the fittings, drain valve or relief valve
- Repeated repairs on a unit past its first decade
A heater with a failed igniter or element and a sound tank may only need a part. Once the tank leaks, replacement is the only real fix.
What's local in Frederick
Your water provider depends on which side of I-25 you live on. The Town of Frederick serves everyone east of the interstate, Left Hand Water District serves residents west of it, and Central Weld County Water District serves part of town. The Town's water is Colorado-Big Thompson supply from Carter Lake, treated at the Carter Lake Filter Plant and disinfected with chlorine. The Town's report doesn't give a hardness figure.
The Building Department at 401 Locust Street handles permits, inspections and contractor registration, reachable at 720-382-5516 or [email protected]. Its page doesn't spell out whether a heater swap needs a permit, so have the plumber confirm. One local detail: Frederick inspectors may verify the identity of the plumber of record at inspection and can hold the inspection until that's done, so the person who pulls the permit should expect to be involved.
Black Hills Energy is the gas utility. If you smell gas, leave the house first, then call 911 and Black Hills using the number printed on your gas bill.

When you call
An independent plumber who serves Frederick will pick up. Tell them the heater's size, fuel and age, where it sits, and whether it's leaking now. Ask that the quote spell out the permit and inspection, any code work and haul-away so you can compare prices on equal terms. If the tank is leaking, close the cold valve above it and shut off the gas or power while you wait.
