Outdoor spigots
A spigot that will not shut, or one that has leaked inside the wall since a freeze, is a fixture repair. Take the hose off in the fall and close the inside shutoff, if the spigot has one.
Faucets, disposals and small parts
Cartridge, washer and seat are the usual parts behind a dripping faucet. Where parts can be found we rebuild it, and where not we fit a new faucet. A disposal that only hums is jammed, and one leaking at the housing needs replacing.
Pick the page that fits the trouble. Drain cleaning handles water that will not leave, and leak detection and slab leaks handles water that has gone where it should not be, such as behind a wall or under a slab. Every other service sits on the main page.
