We had a window break in 2025, Greg was given the job based upon pricing and quick turnaround. We quoted our entire home this year and we went with Greg based on his respectful approach, known good craftsmanship and again, reasonable price. Both projects went extremely smoothly, all workers were pleasant and hardworking. I would definitely recommend Greg and his team to anyone and will be a customer again, if need be.

Greg and his team are professionals that provide an outstanding service experience. Their products, installation, and craftsmanship are superior. They were so respectful of my home and often it was cleaner when they left than when they arrived. I enjoy my windows and doors every day. I will always come back to Hartmann Windows and Doors for my future needs and recommend them highly to others for their window and doors needs.

We recently had all the window glass in our house replaced by Hartmann Windows and Doors. Several other window companies had said it couldn’t be done but Greg Hartmann sourced the glass and installed it for us. We are extremely happy with the results and would recommend Greg to our family and friends.

Greg outfitted all the windows in my new home. He spent a great of time making sure our selection was fitting for what we thought with suggestions on selection options. He had a great vision on how it would turn out. Everyone that comes to the house comments on the amazing window design and quality.
