Flex Plumbing & Heating

Flex Plumbing & Heating is a Malden, MA plumbing and heating company that, on paper, has been around either six or nine years depending on which of its own listings you read — its website says it's been operating since 2020, while its Thumbtack profile puts it at nine years. Either way, the work itself has a clear shape: garbage disposal installs, water heater swaps, sink and bathtub work, and the occasional full-bathroom remodel. The reviews are close to unanimous. Google shows a 5-star average across eight ratings, and a 2025 review described a same-day water heater replacement at 'a great price,' with the crew asking the right questions ahead of time to bring the correct parts; another 2025 review credited the company with a seamless plumbing upgrade on a remodel, completed on time. An older but deeper thread of reviews on Thumbtack — 4.9 stars across 64 ratings, though only five from 2020-2021 are quoted here — tells a consistent story about garbage disposal installs and small fixture swaps done cleanly and on schedule, one customer calling it their 'go to place' for future plumbing work. One thing worth asking about directly: the name attached to the work isn't consistent across sources. The Thumbtack reviews all describe a technician named Rafael ('Rafa') Marques doing the job personally, while the company's BuildZoom listing names Eric Gonzalez as owner. Building-permit records on BuildZoom show 10 permitted jobs pulled over the past three years, mostly 2025 plumbing and gas work, and list an active Massachusetts Plumbing Business license, #5049 — though BuildZoom flags that license as one it hasn't independently verified, so it's the directory's claim rather than a confirmed status. This looks like a solid pick for routine plumbing work — a water heater, a disposal, a leaking fixture — with a track record that holds up across two different review platforms. Before booking, it's worth confirming who will actually be on the job and double-checking that Plumbing Business license #5049 directly with the state.
