    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.

Frequently Asked Questions About Sullivan Plumbing & Heating Inc

How often should I get my drains cleaned?

It's recommended to have your drains professionally cleaned every 1-2 years. However, if you notice slow drainage or unpleasant odors, it’s a good idea to schedule a cleaning sooner.

How can I prevent future drain clogs?

Avoid putting grease, large food scraps, or non-flushable items down the drain. Use drain covers and regularly clean them to catch debris.
