Tankless Water Heaters

Tankless heaters heat water on demand, so you don't run out and you get back the space a tank takes up. We install, repair and maintain them.

Heat Pump Water Heaters

A heat pump water heater moves heat from the air into the water instead of making heat from scratch, which makes it one of the most efficient ways to heat water.

Sump Pump Repair & Installation

A sump pump that fails in the first big storm is the one you find out about too late. We repair, replace and install pumps, and test them before the rain does.

Sewer Lateral Repair & Replacement

The sewer lateral is the pipe that carries everything from your house to the city main, and it is yours to maintain. We inspect it, repair it and replace it when it has to go.

Earthquake Shut-Off Valves

An earthquake valve closes the gas line automatically when the ground shakes hard enough, so a broken line does not turn a quake into a fire. We install and test them.
