5-Star Reviews from Northern NJ Homeowners
See why Diamond Plumbing is the most trusted plumber in Northern New Jersey.
Diamond Plumbing saved us during a burst pipe emergency at 2am. They arrived within 45 minutes and had everything fixed before morning. Absolute lifesavers — highly recommend!
Had a major sewer backup in my Essex County home. Diamond came same day, did a camera inspection, and fixed my sewer with trenchless repair. Professional and efficient!
Called Diamond for drain cleaning after our kitchen sink kept backing up. They hydro-jetted the line and it's been clear for months. Great service at a fair price!
