What is the average price per sq-ft for tile installation around Chicago Illinois?

It varies from contractor to contractor. Size and type of tile. Design. Cuttings, edges, corners, doors, closets, islands, etc. Location. It is best to get a bid (at least 3-4). Make sure your bids have references and pictures. Remember you get what you pay for. The lowest bid may not be the good and may have hidden costs and sloppy work. A quality tiler is worth the price you pay and you are pleased with the work.

I have bid on many tile jobs and I wasn't the low bidder, but I was honest and thorough in what needed to be done and how much it would cost. I got the job and the homeowner was very pleased with the work
