Superior Sewer & Drain Service is family-owned & operated sewer & drain cleaning business out of Groton/Mystic, CT. Built from the ground up and started with a simple drain snake... we are now in our 7th successful year in business, relying on the word of mouth and our much appreciated 5 start reviews from our very satisfied customers. 

My name is Kevin Olenik and I am the owner and the service technician of Superior Sewer & Drain Service. I started this company back in 2013 with my wife Sabrina who runs this website and other things behind the scenes. After working for a big rooter company, I started Superior because I wanted to be free to practice my own beliefs and principles. My goal as a company has always been to provide you, my customer, with honest and upfront rates, quality service and with lasting solutions you can trust and count on.
