Water heater repair fixes problems like no hot water, leaks or strange noises; replacement swaps out a failed or aging unit. Call 540-200-2302 to get connected with a licensed water heater contractor in the Roanoke area.
Troubleshooting no hot water
- Electric heater: check the breaker. A tripped breaker or failed heating element is a common cause.
- Gas heater: check whether the pilot light is out. If you smell gas, leave and call 911 or your gas utility from outside.
- Lukewarm water only: often sediment buildup or a failing element or thermostat.
- Water around the base: a leaking tank usually means replacement. Shut off the cold-water supply valve on top and the power or gas.
Water heater replacement
Tank water heaters commonly last around 8 to 12 years. If yours is in that range and leaking or failing, replacement is usually better value than repair.
When you get quotes, ask about tank size, energy efficiency, haul-away of the old unit, and whether a permit and inspection are included.
Tankless water heater installation
Tankless units heat water on demand and take up less space. They cost more up front and may need gas line, venting or electrical upgrades. A licensed contractor can tell you whether your home is a good fit.
How to make a water heater last longer
- Have the tank flushed to remove sediment. Many manufacturers suggest yearly.
- Have the anode rod checked every few years.
- Test the temperature-and-pressure relief valve.

Common questions
Should I repair or replace my water heater?
If the tank is leaking or the unit is near the end of its typical 8 to 12 year life, replacement is usually the better choice. A failed element or thermostat on a younger unit is often worth repairing.
Is a leaking water heater an emergency?
It can be. Shut off the cold-water supply valve and the power or gas, then call. See our emergency plumber page.
Do I need a permit to replace a water heater?
Often, yes. Ask the contractor whether the permit and inspection are included in the quote.
