What Lawrenceville says about us
★★★★★ 4.9 average from 800+ Mercer County jobs
“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.”

Plumbing in Lawrenceville — your questions
Do you offer same-day plumbing service in Lawrenceville?
Yes. We keep same-day slots open across Mercer County, so a licensed plumber can usually be in Lawrenceville the same day — with 24/7 dispatch for emergencies. Call early for the best window.
Do you charge for estimates?
For scheduled work, the diagnostic visit is a flat, upfront fee that we credit toward the repair if you book it. You'll always get the full price in writing before we start — no surprise charges for parts, labor, or hauling the old unit away.
Are you licensed and insured in New Jersey?
Yes. Every repair is done by or under a licensed NJ Master Plumber, and we're fully insured. Plumbing in New Jersey legally requires a licensed plumber — ask anyone cheaper to show you their license number.
Do you offer emergency service?
Around the clock, every day. Burst pipes, sewage backups, and no-water emergencies get a licensed plumber dispatched right away, with a typical arrival around an hour anywhere in Mercer County.
Should I repair my water heater or replace it?
If it's under about 8 years old and the tank isn't leaking, a repair usually makes sense. Once it's older, rusting, or the tank itself is weeping, replacement is the smarter spend — and a good moment to consider a tankless unit. We'll tell you honestly which way we'd go.
A local crew in every town we serve
We cover every town in Mercer County. Pick yours for local details — same-day service and licensed plumbers who know the neighborhoods, the older homes, and the quirks of the local water lines.
