Clark Plumbing & Heating Solutions

Clark Plumbing & Heating Solutions is a one-man-and-a-small-crew operation out of Waltham, built around Bill Clark. The company's own website claims more than three decades in business, though its BBB profile — where it holds an A+ rating but isn't accredited — lists just 14 years; worth asking Bill directly which is accurate. What's not in dispute is the plumbing license, which the state registry verifies active. The reviews describe a plumber who diagnoses carefully rather than guessing. In a 2022 review, a customer said Clark Plumbing was the third company called after months of inconsistent hot and cold water that two other plumbers had misread — technician Scott traced the real cause through what the customer called "a clever process" and fixed it for less than the earlier, wrong quotes. Another 2022 review made a similar point: Bill and his team, the customer said, only charge and replace what needs to be replaced, walking them through the physics of the system rather than just swapping parts. The record also shows a willingness to go beyond a scheduled job. In a November 2025 review, Bill talked a customer through a basement injector-pump leak over the phone, free of charge, so it would be fixed before Thanksgiving guests arrived. In a 2022 review, Bill and Alex replaced a failing air-conditioner condensate pump, two valves that weren't up to code, and a leaking water heater in one visit, leaving the basement dry and the work neat. Scott, in a separate 2022 review, resolved a water-pressure problem, installed a new faucet, and swapped a garbage disposal in under two hours. Several reviews also describe plumbing support during larger renovations — disconnecting and reconnecting a stove and sink around a kitchen remodel, including a same-day return during a snowstorm to get a customer's kitchen back in service, and detail work during a bathroom renovation to make sure fixtures worked better than before. For plumbing work — from a diagnostic puzzle other plumbers missed to a straightforward install — the pattern here is consistent: careful diagnosis, fair billing, and technicians (Bill, Alex, Scott) reviewers name individually and say they'd call again.
