Tom - Palos Hills, IL
“I would like to say thank you for the wonderful job you did at my house. Your staff is extremely experienced and hard working. They replaced all the windows and patio doors in two and a half days. A special shout-out to Eric who worked nonstop till 6:30pm for two of the days. He’s a machine. Bobby you should be very proud of both he and Sean, their work is impeccable. I highly recommend this company, 5 stars plus. Again, thank you for a job well done. Respectfully, Tom Collins."
