I had a deck built on the back of my 3 flat back in april of 2014. DY Improvements did an excellent job. They have 2 locations. Orland park il and schererville in (maybe merrillville). I wish i had the number for you. I will look for it, and post it if i can find it. Theyre a smaller company but do quality work. The managed to do my deck and stairs under a difficult situation. There was absolutey no parking at my house here in wrigleyville. It was a week long job and they managed to get it done at ease. They also did several repairs in my neighborhood for others after my neighbors approached them after seeing the quality of work.
