Dan DeVries of Authentic Installations replaced 29 windows, 2 patio sliding doors and a front and back door in our home, in January 2016. The work was completed in the time frame given, was of excellent quality and workmanship, and all the appropriate clean-up around our house was also done. Dan was very personable and thoroughly professional, kept us informed throughout the entire process of what was being done and was always willing to answer any questions we had. Our home looks like it has literally had a “face-lift” and we love the updated appearance! We would highly recommend him for any window/door installation needs you may have.
