Best Mechanical Contractor in Chicago IL

Keith was professional, courteous, clean, respectful, took time to explain all options and process and thorough. He addressed multiple issues, worked magic and made a very difficult job look easy. The multiple skills possessed by Great Lakes' professional is admirable and commendable. I have high standards and expectations which Keith & Great Lakes met and exceeded. They go the extra mile. The owner himself came and spent the day assisting Keith. I can't say enough good and would recommend them in a second! Honest, reliable, on time, professional, respectful and clean! AWESOME!
