Bill Clark answers his own phone. It comes up again and again: a November 2025 customer with a leaking basement injector pump and guests due before Thanksgiving reached him while he was out of the office, and he asked for a photograph and talked them through it. A November 2024 reviewer put "he answered his phone" on their list of reasons for five stars. Clark Plumbing & Heating Solutions works from Rosemont Avenue in Waltham on residential plumbing and heating, with 24/7 emergency technicians on its own account. Its Massachusetts plumbing licence, 5104-PL-C, is active, and its Better Business Bureau page carries an A+ without accreditation. The jobs customers describe cover the full domestic range. A 2022 customer listed water heaters replaced, a standing shower built, burst pipes fixed, heating maintenance done and fixtures installed over several years. Another that year had a dilapidated air-conditioner pump, two valves not up to code and a seeping water heater handled together. A 2022 household that had been getting only lukewarm water from both showers for months brought Clark in as their third plumber. Two customers, in December 2024 and July 2025, had bathroom renovations where Bill put in the extra time to leave the rest of the house working better than it had before. Worth knowing before calling: its BBB profile lists 14 years in business while the company's own site says more than three decades. A strong call for a water heater, an emergency leak, or the plumbing side of a bathroom or kitchen job around Waltham. Ask what an after-hours call-out costs, and get the scope written down if it is part of a renovation.
I called Bill about a leak related to my basement injector pump. I have guests coming to visit before Thanksgiving, so wanted to to fix the issue quickly. Even though Bill was out of the office when I called him, he asked me for a picture of the leak and he walked me through the repair, free of charge. Five stars isn't enough; I highly recommend Clark Plumbing

Bill is detail oriented and is Stright forward - and with our recent bathroom renovation, he put in the extra time and effort to make sure everything in the house was working better than before!

Bill was super nice neat on time curteous and he answered his phone!!! I definitely recommend him highly!!!
Seems to me like the negative reviews on Google for Clark Plumbing & Heating are either from bots or horrible people who just want to mess with Bill's ratings. Five stars for Bill for a few reasons: -He answered the phone when I called -He was honest about what he could and couldn't do -He came to give a quote and repair a leak a day after I called asking for help -His pricing is fair and not above market -He was respectful when he entered our home and even took off his shoes when asked (we take off shoes in our house) -He was professional and seemed like a genuinely nice person - who doesn't want to work with a nice person? -The work he performed was top notch - the leak is gone (he repaired someone else's shoddy work in our home) Thank you Bill for your help and your number is now permanently saved in my phone!
