“Mystery leak spiking our water bill for months. They found it inside a wall in twenty minutes and patched it with one small cut. Finally. Fair, fast, and clean.”
Priya K.Lawrenceville
“Water heater died on a Sunday. Called Capitol, a licensed guy was here in under an hour, and we had hot water again by dinner. Flat price, no weekend gouging.”
Dana M.Hamilton
“Slow drains in a 1920s house everyone else wanted to tear into. They cameraed the line, found roots, and cleared it trenchless. Explained everything, no mess left behind.”
