A pipe exploding in the basement, a hole eaten through cast-iron plumbing under a bathroom, a clog far from the garbage disposal — Mark's Plumbing & Heating in Woburn is the kind of shop people call mid-emergency, and the reviews describe owner Mark Hammond showing up fast. Google shows 4.3 stars from 23 ratings, and BBB carries an A+ grade for the business, a sole proprietorship Hammond has run since June 2004. In a 2023 review, a customer described being turned away by other companies for the week before Mark came out within an hour of being reached and had the water back on within 25 minutes of an exploded basement pipe. A 2024 review described similar urgency — arriving within 15 minutes to a burst cast-iron pipe feeding a toilet and sink. In a 2025 review, a customer described a quick valve repair under a kitchen sink, with Mark taking the time to explain the work along the way. One account stands apart: a 2022 review titled "Beware of Terrible Professionalism! Unreliable!" described early responsiveness on a frozen-pipe repair that, by the reviewer's account, soured once they sought a quote for a separate washer/dryer hookup job. For an emergency plumbing call in Woburn, the record here points to a fast, hands-on response — worth keeping the 2022 account in mind if the job in question is a larger, scheduled project rather than a same-day fix.

We had a hot water valve leaking below our kitchen sink. Mark was able to stop very quickly, changed the old valve, checked the adjacent pipes for potential problems, and even offered to change my drinking water filters. During the visit he was very courteous and informative. I was curious about the work and he took the time to explain how things work (with examples!) he did a great job and cannot recommend him highly enough.
We had an emergency at our home and needed a plumber ASAP. We called Mark's plumbing and he came down within 15 minutes to check out the problem. The problem was we had a hole in the cast iron pipe that connects to the toilet and also the sink in the upstairs bathroom. This also connected directly to the sewer line that goes outside the house. He came over and did a professional job along with another problem that we had with the bathroom sink upstairs. He was such an incredible help that day. He was friendly, professional and caring at all times. We highly recommend him as a plumber. We will be calling him for other projects we are planning. Thank you Mark
Gas water heater replacement ‐ prompt service and great workmanship
I was so grateful to find marks plumbing when my pipe in the basement exploded with water. All other companies wouldn't even schedule me that week. Got a hold of mark and he came by to check it out within an hour after his first job of the day. He was honest about what the issue was, showed me what needed to be replaced and had my water back on within 25 minutes. I will be keeping is number handy.
He came immediately after I called him and was able to quickly identify the issues and fixed all of the issues quickly. The pipe clogging issue was a hard one since the site clogged was far from the garbage disposal . Mark did a great job to have it fixed. In overall, I am very satisfied with Mark’s quality and responses. Mark was also very patient too!
