PROTECT YOUR HOME
Why This Service Matters
Your water heater works hard every single day. Keeping it in good shape isn’t just about comfort — it directly affects your energy bills, your home’s safety, and the lifespan of the unit itself.
- A failing water heater can leak or rupture, causing serious water damage to your home.
- Sediment buildup forces your unit to work harder, increasing energy consumption and monthly costs.
- Most traditional water heaters last 10–12 years — an aging unit is a ticking clock for unexpected failure.
- Tankless water heaters can reduce energy usage by up to 30% compared to traditional tank units.
- Licensed installation ensures your unit is properly vented, code-compliant, and covered under warranty.

Olympia Plumbing Questions
If your unit is under 8 years old and experiencing minor issues — like a faulty thermostat or a bad heating element — a repair is usually the right call. But if it’s over 10 years old, showing rust or corrosion, leaking from the tank, or failing to heat water consistently, replacement is likely the better long-term investment. We’ll give you an honest assessment and let you decide.
Common warning signs include: no hot water or inconsistent water temperature, rusty or discolored water, a popping or rumbling sound from the tank, water pooling around the base of the unit, or a noticeable increase in your energy bills. If you notice any of these, call us — catching the problem early can save you from a much bigger headache.
For many homeowners, yes. Tankless units heat water on demand, so you never run out — and they use significantly less energy than traditional tank heaters. The upfront cost is higher, but the long-term savings on energy bills and the extended lifespan (often 20+ years) make them a smart investment for most homes. We can walk you through the numbers so you can make the right call for your situation.
Most standard water heater replacements take 2–3 hours from start to finish, including removal of the old unit. Tankless installations may take a bit longer depending on venting requirements and any necessary upgrades to your gas line or electrical panel. We’ll give you a clear timeline before we start.
Yes. Our licensed plumbers are experienced with both gas and electric water heaters — traditional tank units and tankless models. Whatever system you have, we can repair, maintain, or replace it.
We recommend an annual inspection and flush to remove sediment buildup and check key components like the anode rod, pressure relief valve, and thermostat. Regular maintenance can extend the life of your unit by several years and keep it running efficiently.
