About Sullivan Plumbing

Sullivan Plumbing is a family-owned and operated plumbing, sewer, and septic business, proud to serve Union County and the surrounding Southern Illinois communities. For years we’ve been one of the area’s go-to names for this work — the kind of company people are comfortable recommending to a neighbor. We’re a licensed Illinois plumbing contractor, fully insured, so everyone’s protected while the work is being done, and we use quality, certified products in your home or business rather than the cheapest thing off the shelf. And we’re intentionally not a high-volume, 24/7 operation: we’re a small team that stays busy through referrals, and we’d rather do fewer jobs right than rush more of them.

Customer Reviews

“We only trust our plumbing repair issues to Sullivan Plumbing. From burst pipes, hard-to-get-to clogs, water heater replacements, toilet replacements, grease trap installs and sump pump repairs we have not had a problem that they could not handle. When it’s an emergency they arrive fast but when it’s something that can be scheduled they show up on-time and are quick to fix the problem and clean up completely after themselves. They are professionals at their trade. Their truck has just about every tool and replacement part they need. Lastly, their price is very reasonable. I honestly can’t imagine using anyone else.”

“Replaced our leaking water supply piping. Excellent work!”

“We recently experienced a clogged drain that proved to be beyond my ability to fix… After determining that this wasn’t a true emergency situation the person I talked with asked if we could wait until tomorrow at 9:30 AM. I was very pleased… The next morning two men arrived exactly on schedule in a large, well equipped truck… 24 minutes after they arrived the drain was clear. They packed up their equipment and cleaned up after themselves… pleasant, efficient, and courteous. It’s getting difficult to find a plumber in this area… they did a first class job. I can highly recommend Sullivan Plumbing based on my experience with them.”

“I highly recommend giving the Sullivan Bros. a call. All around quality service, reasonable pricing and great guys.”

“Excellent service. They were doing a job near me and were able to start with little wait. Did a great job; as new homeowners we appreciated all they did.”

"No one better than these guys! Great work diagnosing and fixing the problem. Highly recommend them."

"Had service on Friday AM. On time and did super fast work. Great value!"
