Mystic Valley Home Services is the kind of plumbing company people call when water is already moving in the wrong direction. In a March 2026 review, a customer said a midnight pipe burst flooded a new kitchen and the team left dinner to help; other homeowners describe burst pipes, failed water heaters, leaking valves, and emergency calls handled within an hour. The Arlington company says it is family-owned and operated by Matt Sullivan, who personally oversees each project, and serves Arlington and nearby communities. Its website describes plumbing, heating, and cooling work, including same-day plumbing, boiler service, and ductless mini-split installation and repair. Google shows 139 ratings, and written reviews from April through August 2026 repeatedly mention prompt arrival, clear communication, clean work areas, and quoted pricing. The work described by customers ranges from water shutoff valves and bathroom faucets to pressure regulators, expansion tanks, boilers, tankless water heaters, and complicated kitchen fixtures. In a June 2025 review, a homeowner said a water-heater failure was addressed the next day after a late-night call; in a September 2025 review, another described a two-day replacement of bathroom sinks, vanities, basement pipes, and an old pipe. The company has also handled a gas dryer replacement and referred one heater problem to a longer-term specialist when that was the right next step.

If you're like me, you've either been cooked multiple times by bigger companies in the home repair industries taking advantage of you - or you're trying not to be in that situation. And you have to deal with an anxious spouse on top of all that. Long story short, we saw developing stains on our kitchen ceiling from leaks in the guest bathroom upstairs. Called Mystic Valley. Matt and his team came in the very next morning. Due to the leaks being super stubborn and having multiple sources, they ended up coming to our place a total of three times to diagnose, repair, tighten, and apply sealant in all the appropriate places with time to dry, with the latter two visits being completely free of charge. Our guest bathroom is now leak-free. We're still trying to figure out which guest was responsible for creating these leaks. Just kidding. Matt is a super amicable guy and it's clear that his team genuinely enjoys what they do. They treated us with the utmost courtesy. Feels good when a company actually cares. We're very satisfied with their level of service and commitment and are pretty much set with Mystic as our go-to plumbers. Happy wife, happy life.
We have used Mystic Home Service twice. Both times, they were very prompt and responsive , which I appreciate. There was an issue with the second repair due to some technical issues on the company’s side. However, the manager responded promptly, took responsibility for the situation, and made sure the issue was fixed properly without any additional charge. The team came back, addressed the problem quickly, and did a great job. My kitchen sink feels like a new one! I really appreciate the manager’s honesty, responsiveness, and commitment to making things right. I will definitely use Mystic Home Service again and will gladly recommend them to my friends and family. Thanks, Matt and team!
Matthew Sullivan and his associate did a great job in fixing a water leak in the cellar, doing their work with skill and professionalism. Besides their excellent work, they were friendly and courteous, explaining the steps they were taking to resolve the issue. I wouldn't hesitate to contact Mystic Valley if needed again or to recommend them to anyone who's looking for high quality plumbing services performed by good people. Well done.
5 stars for Matt! He was very professional and showed up right on time for our appointment. I had just installed a new vanity myself, but the plumbing connections weren’t quite right and I ended up with a small leak. Matt came out the first time and helped with part of the issue, then came back a second time with his colleague to properly reconnect everything. They took their time and made sure the job was done right. Everything is now completely leak-free, and I can finally put my things in the vanity cabinet without worrying about water damage! Matt was also reasonably priced. I really appreciate his professionalism and the care he put into fixing the problem. I would definitely recommend him!
Polite, prompt, professional service very time at a reasonable price. Such a great experience. I have had Mystic Valley Home Services to my house three times for services and repairs and will continue to do so!
