About us

My name is Mykhaylo (Mike) Mykulyn. I live in Downers Grove and next year will be 25 years since I started working as a contractor. For this quarter of the century I gained a great amount of experience in exterior renovation and general contracting. I have installed every possible kind of window and door that was produced in North America and recently I even installed windows imported from Poland and Germany. I have done work for many custom builders in both residential and commercial areas and those jobs were from small caulking work to major custom facades. Our crew is small but the work is impeccable. I also have great experience in all kinds of siding: steel, vinyl, hardy, smart side and aluminum composite panels. I own a seamless siding and gutter machine that helps me keep prices reasonable. We do 24 hr. emergency service in case you need help on the weekend or in the evening. We also do glass replacement, roof and siding repairs and aluminum capping.

Seamless Metal Gutters Repair
Mike also repaired/replaced and painted rotting wood, replaced a light fixture, and fixed a door lock to work in a house that’s settling. I found him very knowledgeable, efficient, competent, excellent at listening to my concerns and explaining options clearly. It was very easy to coordinate plans and timing. He was reasonably priced. He’s also a pleasant guy! I was very, very pleased and impressed by the experience and the results.

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.
