Repair vs. replace guidance
During every visit we evaluate the age, condition, and safety of your water heater. If a simple repair will give you more reliable years of use, we'll explain that. If the tank is near the end of its life or unsafe, we'll recommend replacement options and explain total cost of ownership.
All major water heater types
We work on traditional tank-style heaters, high-efficiency models, and modern tankless units. Our technicians are trained to follow manufacturer guidelines and local codes to keep warranties intact where possible.
When is it time to replace instead of repair?
Most tank-style water heaters last 8–12 years. If yours is in that range and showing signs of rust, leaks, or frequent breakdowns, replacement may be the safer, more cost-effective option. Tankless systems can last longer but still require maintenance and occasional repairs.
We'll share clear pros and cons of repairing now versus replacing, including energy costs, reliability, and potential risk of sudden failure.

Water heater repair FAQ
How long does a typical water heater last?
Traditional tank-style heaters usually last 8–12 years, depending on water quality and maintenance. Tankless systems can last longer with regular flushing and service.
Should I repair or replace my water heater?
If your unit is relatively new and the issue is minor, repair often makes sense. If it's older, severely rusted, or leaking from the tank itself, replacement is usually the safer option. We'll walk you through each choice with clear pricing.
Do you repair tankless water heaters?
Yes. We service many major tankless brands and can help with error codes, ignition problems, and performance issues. We also provide annual maintenance like descaling and filter cleaning.
Can I prevent future water heater issues?
Regular maintenance like flushing sediment, checking anode rods, and verifying safety valves can extend the life of your heater. We can set up a simple maintenance schedule for your home.
