Repair, Replacement, Tankless & Commercial

Water Heater Repair

Pilot lights, heating elements, thermostats, and leaks. We identify the fault and fix it promptly so your routine gets back to normal.

Water Heater Replacement

When a tank is worn out, we help you choose the right size and type, install it to code, and remove the old unit.

Tankless Water Heaters

Endless hot water and lower energy bills. We install and service tankless systems for homes ready to upgrade.

Commercial Water Heaters

From gym showers to restaurant kitchens, we keep commercial hot water running with installation, maintenance, and urgent repairs.

Recirculating Pumps

Tired of waiting for hot water at the tap? A recirculating pump delivers it fast. We install and replace them, like our recent job in Oceanside.

Maintenance & Flushes

An annual flush removes sediment buildup that shortens tank life and drives up energy bills. Quick, inexpensive, worth it.

Know The Signs

Signs Your Water Heater Is About To Go

Any one of these is worth a look. Two together usually means you are choosing a replacement soon, on your schedule or on the tank's.

Rusty Or Brown Hot Water

Cold water clear and hot water rusty means the tank is corroding from the inside. Once the lining goes, no repair brings it back.

Never Enough Hot Water

Showers that turn cold halfway through usually mean sediment has taken up the space your hot water used to occupy.

Popping Or Rumbling

That is sediment cooking against the burner. It wastes gas, it stresses the steel, and it gets louder as the layer thickens.

Water Around The Base

A wet floor at the tank is either a fitting or the tank itself. One is an easy repair and one is not, and we will show you which.

Ten Years Or Older

Most tanks run eight to twelve years. Past ten, replacing it on a Tuesday costs less than replacing it after it floods a garage.

Pilot Will Not Stay Lit

Usually a thermocouple, sometimes the gas control valve. Both are repairs worth making on a tank that is otherwise sound.

The Honest Question

Repair It Or Replace It

We would rather fix your water heater than sell you one. These are the lines we use to decide, and we will walk you through them at your tank.

Frequently Asked Questions

Your Water Heater Questions, Answered

How often should I flush my water heater?
Once a year. Flushing removes sediment buildup that reduces efficiency and shortens the lifespan of the unit.
What is the average lifespan of a water heater?
8 to 12 years, depending on water quality, usage, and maintenance. Past that range, replacement usually beats repeated repairs.
What are the signs of a failing water heater?
Rust or corrosion on the tank, leaking water, reduced hot water supply, rumbling or popping noises, and rising energy bills.
Should I repair or replace my water heater?
If the unit is under 8 years old and the fix is minor, repair usually makes sense. An older tank with a major fault is better replaced. We price both options so you can decide.
What is a water heater anode rod?
A sacrificial metal rod inside the tank that attracts corrosive minerals, protecting the tank itself. Replacing it periodically extends the tank's life.
