Water heater repair & tankless installation in Denver
No hot water, or a tank on its last legs? We repair, replace, and upgrade to tankless — usually with hot water back the same day.
A water heater rarely dies at a convenient time. The good news: most swaps are a same-day job, and a failing tank is a chance to fix the thing that's been rumbling in your basement for years.
Repair or replace?
If your tank is under about 8 years old and it's a part that failed — thermostat, heating element, gas valve, thermocouple — a repair usually makes sense. Once a tank passes 10–12 years, or if the tank body itself is leaking, replacement is the smarter money. A leaking tank never gets better, and it's one flooded basement away from a much bigger bill.
Tank vs. tankless
- New tank. Lower up-front cost, familiar, 8–12 year life. A solid choice when budget is the priority.
- Tankless. Endless hot water, wall-mounted (reclaims floor space), 20+ year life, lower energy use. Costs more up front and may need gas, venting, and electrical updates — worth it for many Denver homes.
Denver hard water, handled
Denver's hard water is tough on water heaters — sediment hardens in the bottom of a tank (that's the rumble) and scales up tankless heat exchangers. We size and install with the right flush schedule or water treatment so your new unit actually reaches its rated life instead of dying early.
Common questions
Should I repair or replace my water heater?
Under ~8 years with a failed part: repair. Past 10–12 years, or a leaking tank body: replace. A leaking tank only gets worse.
Is a tankless water heater worth it?
Endless hot water, less space, 20+ year life, lower energy use. More up front, but no 50-gallon flood when it fails. In hard-water Denver we install with the right treatment so it lasts.
How long does installation take?
A tank swap is usually a same-day 2–4 hour job. A tankless conversion often takes most of a day (gas, venting, electrical). We confirm scope and flat price first.
Why does my water heater rumble or run out fast?
Hard-water sediment hardens in the tank bottom — that's the rumble. It wastes energy and shrinks your hot-water supply. Flushing helps; past a point, replacement is the fix.
