Sean Sullivan plumbing has exceeded all our expectations with a simple phone call. His crew was available to handle a leak that we had in a wall they were able to find it and repair it. The cost was very very reasonable. We have been using Sean Sullivan plumbing for years now and as a real estate agent, I’m always recommending them. They have never failed to deliver.!!

Was referred to Sean and his team by a close friend. It's extremely difficult to find a plumber you can not only trust and rely on but also one that's prompt and does an amazing job. That is what I received from Sullivan Plumbing. They eliminated an issue over night I'd be dealing with for years and I cannot thank them enough. I will definitely keep in touch for any and all issues. Happy Holidays to you all.. You sure made mine happy.
