Kook & Son, Inc.

Kook & Son, Inc. has served Jersey City residents for decades as a family-owned plumbing and HVAC contractor, operating out of their local office on Communipaw Avenue. The company holds a state contractor license and maintains a physical presence in Hudson County, serving single-family homes, apartments, and small commercial properties across Jersey City neighborhoods including Journal Square, McGinley Square, and the West Side. They are open Monday through Friday from 8 AM to 4:30 PM, with Saturday and Sunday available for emergency calls only. The business employs a small team, combining father-and-son experience with longterm staff who know the City's older housing stock, particularly the pre-war apartment buildings where galvanized pipes and original radiators present unique challenges.

What distinguishes this contractor is their willingness to tackle older heating systems that many companies refuse to touch, including cast-iron radiator repairs and boiler replacements in buildings over 50 years old. They handle both plumbing and HVAC work, meaning a single technician can address related issues like a leaking water heater affecting heating performance. The company provides free estimates for major jobs and will present itemized invoices, though recent reviews indicate some customers felt certain line items, particularly freight charges for materials and travel time, were not clearly explained upfront. Their service department stocks common parts for legacy heating equipment, allowing same-day repairs on standard valve replacements and thermostat exchanges.

Customer experiences vary considerably. Irene Lin praised the team's speed in October when her tub leak threatened the unit below, noting the plumbers cleaned up thoroughly before leaving. She hired them again in April for a boiler replacement and reported the same efficient, neat work. However, Jason Jonas documented an unresolved knocking radiator issue where the technician left mid-job claiming the problem was solved when the sound persisted, and subsequent calls went unanswered for weeks. Another customer, Jonas Duss, felt the final invoice included undisclosed charges that pushed the total well above the initial quote.
