Plumbing Services Dover, NH

First check the basics: on a gas unit, see whether the pilot or burner is lit; on an electric unit, check the breaker and the reset button on the thermostat. If you see water pooling around the tank or smell gas, shut off the water and gas supply and call our Dover line at (213) 579-0947 right away — crews across Sawyers, Dover Point, Durham Historic District carry replacement elements, thermostats, gas valves, and full water heaters for a same-visit fix.

Often just the failed section. If the surrounding pipe is still sound and the leak is isolated, a spot repair on your Dover line is far cheaper than a full repipe.

When the pipe is old galvanized steel throughout, we'll walk you through why repiping pays off long term.
