Ranshaw Plumbing & Heating maintains a 4.8-star average across 603 customer reviews in Whitestone, NY, reflecting more than six decades of dedicated service to the NYC metro area. The company holds NYC Master Plumbers License #1090 and #2421, enabling them to handle everything from routine repairs to complex violation removal and commercial inspections. Serving neighborhoods across Queens including Flushing, Astoria, Bayside, Jackson Heights, and extending into Brooklyn, Long Island City, and Manhattan, their team provides both residential plumbing and heating solutions alongside commercial services and annual inspection compliance.
What distinguishes Ranshaw from neighboring contractors is their commitment to doing each job correctly the first time, backed by documented licensing and a BBB A+ rating. The company offers comprehensive water heater services, boiler installation and repair, gas leak detection, sump pump work, and specialized oil-to-gas conversions for homeowners upgrading from older heating systems. Their service plans include preventive maintenance tune-ups, smart thermostat installation, and Local Law 152 compliance inspections for property managers. This combination of technical breadth with documented workmanship standards addresses a common pain point: repeat repairs that disrupt households and strain budgets.
Customer reviews highlight specific technicians who resolve problems other contractors left behind. C Scott described a boiler installation where the team arrived prepared, maintained a spotless workspace, and tested every safety component before explaining system operation. Richard Rosenfeld credited Bill with clear communication throughout the service, while Allison coordinated rapid dispatch so heating restored quickly. Ankit Parekh noted Bill resolved four unresolved issues from prior contractor visits in a single service call. These scenarios illustrate why reviewers emphasize the value of thorough diagnostics over quick fixes.
What Customers Say
Of three sampled reviews, all award top marks, with technicians named in each: Bill appears across two reviews for both plumbing and heating expertise, and the dispatcher Allison is noted for coordinating same-day response. Positive sentiment centers on diagnostic thoroughness rather than pricing, contrasting with the reviewer's observation that prior contractors charged for incomplete work.
