William responded to my quote request right away and they were able to come out the next day. Clog was fixed within 30 mins. Really great experience!

Exceeded expectations. The plumber not only solved my toilet issues speedily and effectively but also helped with another minor issue that I wasn't even aware of, but that he noticed right away! When there was confusion about the initial quote and the asked price, the owner addressed it to my satisfaction, and I am very impressed by the attention to customer service and professionalism. The responsiveness and quality is unmatched out of all the plumbing services I have requested. You will be in good hands.

This is the best plumbing company I have ever done business with. They were responsive and pricing was very fair. I would definitely recommend 4S to anyone looking for honest, reliable plumbers.

They were AMAZING! Bill was wonderfully helpful on the phone; Ahmad came out the same day and fixed the problem (that my very handy dad had struggled with for awhile) in less than 30 minutes and was super professional. Highly recommend!

I had an excellent experience with 4S Plumbing. Plumber arrived on time, fully prepared, with a mask and gloves for COVID protection. He fully repaired my toilet, which had been improperly sealed twice by my previous plumber, and explained each step of his process. He was honest about which of my drains just needed minor cleaning out, and which needed full rodding to remove a clog. He provided discounts on the more expensive services and made it clear that his goal was to keep me as a customer for life. I'm extremely pleased with all his work and would recommend 4S to everyone.

I have been dealing with 4S plumbing for few years, every time they provide excellent service that make me come back. Definitely will keep working with 4S plumbing and I believe they are providing the best plumbing service in Chicago.

4S Plumbing turned a bad situation into a great one. We have an ongoing tree roots issue in our main line that needs attention every couple of years. This year we caught it in time before it got ugly in our basement. Thank you Marcus & Bill for the great job you did. We'll definitely use them again and let my friends and neighbors know about the great work they do.

4S Plumbing is amazing. Very fast service & fair pricing. I love these guys.
