William and team reached back out to me and made sure my original was taken care of and then some! Joseph that came was professional, courteous and made sure all my questions were answered! I'm glad we gave 4s another opportunity to fix our sump pump issue, they were prompt and had very flexible scheduling! Thank you William and team!!!!!!!!!

Excellent service and honest dealing, going well beyond expectations. We stumbled on to 4S Plumbing unwittingly through a referral from another plumber that wasn't able to help us. It was a happy accident though. Our plumber Tim was not only professional but an all-around nice guy who was happy to answer questions and look at other plumbing and leak issues around the house.

I have been dealing with 4S plumbing for few years, every time they provide excellent service that make me come back. Two days ago we had problem with bathtub faucet leaking issue, I called 4S, they sent great plumber, Marcus, he is so professional and very nice guy, he diagnosed the issue and fixed it quickly with very competitive price. Definitely will keep working with 4S plumbing and I believe they are providing the best plumbing service in Chicago.

I've lived in many houses & have had to deal with many plumbers. This particular company however is quite unique &special.Not only are they fairly priced, flexible, & reliable;they are incredibly We'll managed. What I mean by this is that the owner of the company often deals with you personally. You don't have to go through layers of people to get some thing done. Bill the owner, Actually Calls customers back himself He is very responsive and available. He has diligent employees from the skilled workers to the support staff reflecting what the company prioritizes from the top down. Highly valued as they are!
