I have used Sullivan Septic both personally and professionally when it comes to fixing and replacing entire septic tank systems. They’re super knowledgeable and most importantly extremely reliable. There is no one else I would recommend.

I’ve used Sullivan for my regular maintenance.
Lately, Ryan has been helping me troubleshoot a potential problem with my system.
Everyone is very knowledgeable and I can tell they care for their customers.
Great local company!
