JCF Plumbing & Heating has recent customers who call John responsive and careful, but one older Angi account describes a serious failure that deserves a direct question before any work begins. In February 2026, a homeowner said John came the next day for a basement leak, made a small repair, and did not upsell; the same review said he offered practical advice for future projects. The work described includes faucets, toilet and shutoff-valve replacement, tub-drain repair, outside faucets, and other household plumbing. A November 2023 review described a toilet and corroded shutoff-valve replacement, while an August 2022 review said bathtub faucet pipes were repaired for the estimated price. Those accounts are dated and should be read as history; the February 2026 review is the freshest written account. The Massachusetts registry verifies active plumber license 9474-PL-M under John Fontana. Google shows 4.9 stars from nine ratings, while Angi shows 3.7 from three ratings. Angi's written set includes an older positive account about responsiveness, plus a February 2021 one-star complaint alleging loose bolts led to a burst pipe, flooding, thousands of dollars in damage, and an unanswered emergency call. JCF may suit routine plumbing repairs and fixture work when you want a small operator who explains options. Before booking, ask how repair connections will be checked, what emergency calls are covered, and what warranty or response process applies if a repair fails.
John is fantastic. We called him when we had a minor leak in our basement, and he came by next day. It was a small fix, he didn't upsell us, and beyond all that, he gave us great advice and local recommendations for future projects we had on our minds. Couldn't ask for more. We will definitely call John again!
John is a great plumber and an amazing person. I hired John to replace a toilet and corroded shutoff valve. This was done in an exceptional manner at a very fair price. When John was finished I mentioned to him that we had an issue with our tub drain and the trip lever. John explained to me the simple process of removing the existing lever and how to replace it which is something I was easily able to do on my own. If you are looking for a plumber that is trust worthy and honest then look no further and give JCF Plumbing and Heating a call.
John changed my outside faucets. Love the new style and absolutely no leaking. Very professional and nice. Highly recommend. Thank you!
John repaired my bathtub faucet pipes. He responded quickly, did a great job, and did the work for exactly what he estimated.
He did not tighten the bolts properly, therefore causing the pipe to snap and explode. This oversight on his part caused 1000s in damage to my house, and the true extent of the damage is unknown at this time. I do know, that when I called him (as my house was flooding) he ignored my calls and texts. A second plumber came out to my house and verified that he did not tighten the bolts right. I’m out $300 plus the damage the flood caused. Please stay away from JCF plumbing. JOhn Fontana is a crook- and shouldn’t be on Angie’s list.
