About John B Hoff & Son
John B Hoff & Son is a licensed plumbing and heating contractor serving Lambertville, New Jersey, and the surrounding communities across Hunterdon and Bucks Counties. With 15 verified reviews holding a 4.8-star rating, the company has built a reputation for reliable residential and commercial service. The business operates from 1500 Route 179 in Lambertville and holds multiple credentials including NJ Master Plumber License 9257, Pump Installer License 0002067, and both New Jersey and Pennsylvania home improvement contractor licenses. Their service area encompasses Lambertville, New Hope, Flemington, Frenchtown, Stockton, Buckingham, and Yardley, along with the broader Hopewell Valley and Solebury Pennsylvania region.
What distinguishes John B Hoff & Son from typical plumbing shops is their specialized certification portfolio and multi-generational expertise. The company employs technicians certified in GasTite Flexible Piping, Wirsbo Radiant Heat Installation, EPA WARDFLEX Installation, and Lead Dust Sampling. These credentials enable them to handle specialized tasks like radiant heat systems, gas piping, and lead-safe renovation that general plumbers often cannot address. Their decades of experience across three generations of the same family provides institutional knowledge particularly valuable for older homes in historic Hunterdon County and Bucks County neighborhoods where plumbing systems may present unconventional challenges.

Joan Arkuszewski called the company "totally professional" and highlighted their reliability in returning calls and showing up on time for appointments. Michael Shier described them as "honest, reliable, and fair" and stated they are the only plumber he will call.
