Repair, replace, or upgrade

Hot water back fast, done right

We service every type of water heater: gas and electric tank units, gas and electric tankless systems, and heat pump water heaters. Whether it's a leaking tank, no hot water, a pilot or igniter fault, sediment buildup, or an error code, we diagnose the problem and give you an honest repair-versus-replace recommendation.

When it's time for a new unit, we install it to code, including the expansion tank, venting, and gas or electrical work, and haul the old one away. Thinking about tankless? You get endless hot water and decades of life, and we'll size it correctly for your home's demand.

A failing water heater rarely waits for business hours, so we offer same-day and emergency service across Boulder County. Call the moment you spot a leak or lose hot water, the faster we're there, the less damage and downtime.

Tankless vs. tank

What's the difference?

Replacing your water heater? Here's how a tankless system compares to a traditional storage tank, an honest breakdown.

FeatureTankless Water Heater (Recommended)Traditional Storage Tank
Hot water supplyEndless, heats on demandLimited to tank size; can run out
Lifespan20+ years typical8-12 years typical
SpaceCompact, wall-mountedLarge floor-standing tank
Energy useHeats only when neededReheats stored water around the clock
Upfront costHigher, offset by longer lifeLower upfront

Tankless isn't automatically the right call, a quality storage tank is often the smarter, more affordable choice for some homes and budgets. We'll look at your hot-water demand, fuel type, and venting, then recommend the unit that genuinely fits.

FAQs

Water heater questions, answered

Repairs start with a service call from $99, applied toward the fix. A new gas or electric tank install typically starts around $1,650, and a tankless install from about $3,500 depending on fuel type, capacity, and any gas, venting, or electrical upgrades.

Yes. A leaking tank or sudden loss of hot water is a priority, we offer same-day and emergency service across Boulder County to limit water damage and get you running again fast. Call us the moment you spot a problem for the quickest response.
Turn off the water supply to the heater, shut off the gas or breaker to the unit, and call us right away. A leaking tank usually means the tank itself has failed and needs replacement, but we'll confirm on site. The sooner it's handled, the less risk of water damage to your home.
It depends on the unit's age and the problem. Tank heaters generally last 8-12 years; if yours is near that range and the tank is leaking, replacement is usually the smart call. A younger unit with a bad element, thermostat, or valve is often worth repairing. We'll give you honest options either way, we won't push a replacement you don't need.
For many homes, yes, endless hot water, a 20+ year lifespan, and a compact wall-mounted footprint. The upfront cost is higher than a tank, and it needs annual descaling in Colorado's hard water. We'll size it for your demand and tell you honestly whether tankless or a quality tank is the better value for your home.
Yes, gas tank, electric tank, gas and electric tankless, and heat pump water heaters. We handle the gas line, venting, and electrical work each one requires, and install everything to code including the expansion tank.
A straightforward tank swap is usually done same-day in a few hours. A tankless install, especially a first-time conversion that needs new gas, venting, or electrical, typically takes most of a day. We'll give you a clear timeline with your quote.
