I hired Mike to replace a third floor window that had cracked from the low temperatures this past winter. He was professional, fast, and clean. Highly recommend him for other window work and I would not hesitate to hire him again.

We hired Mike first to do our soffit, fascia and gutters at our home in Indiana in 2018. After that he did our Chicago house- aluminum work and windows. And finally recently he finished soffit/fascia/gutters and windows capping at our current home in Orland Park. Happy with workmanship!!! Highly recommend him and his crew!

Mike called me immediately. Gave me a fair quote and did a great job in a timely manner. Seamless gutters and downspouts custom made on site. Best of all, my gutters look and work great.

Mike at Gentek was a true professional. He came out on time, honored his original estimate and did high quality work. I would definitely use Mike again for exterior work on my home.
