Panza Plumbing & Heating

Panza Plumbing & Heating works out of Newton, where reviewers know the plumber behind the wrench as Mario — the same person one directory credits with more than three decades as a Massachusetts-licensed plumber, heating tech, and pipefitter. BBB records list the business as open since 2008, though it has never pursued BBB accreditation. The handful of reviews scattered across directories pull in different directions. Some customers say Mario was the only plumber willing to come out right away for an estimate and had a failing boiler swapped out within a few days at a reasonable price, while another called his pricing fair after a quick house call. But at least one customer described the opposite experience — a pipe connection Mario installed was fastened poorly enough that it repeatedly sent water into their basement, both from an indoor line and later from an outdoor sprinkler hookup. Ratings disagree from source to source: Google shows 3.0 stars from just two reviews, while a separate directory counts 4.5 stars across six — with so few reviews behind either number, neither one settles the question on its own. With a review trail this thin and mixed, and a specific workmanship complaint on the record, it's worth raising the pipe-connection issue directly with Panza and getting a second look at any finished work before calling the job done.
