    Kelemer Brothers were amazing in our recent replacement of front door, storm door and adjacent window. The entire experience, from start to finish, was excellent. Gabriel worked with us in a friendly and respectful manner to suggest options that suited our needs and budget, taking extra time to research special options specific to our project. The replacement was completed within the projected time frame and we are very happy with our new front doors! I would heartily recommend Kelemer Brothers!

  • The job went beautifully, in a Victorian house, circa 1912. A cheap vinyl replacement window had warped, would no longer close and lock or keep air out. I had 3 companies/handymen come in, look at the job, and turn down the work, as it was intricate to get the old window out without destroying the vintage woodwork, and tricky to fit the new one in. Nothing in this house is square, i.e., 90°. The fit by Kelemer's workman was a work of art. The window Kelemer Brothers used was much better than the one they ripped out. Afterwards, Gabriel Kelemer personally reviewed the job and gave my tenant and I a full tour of the window and how it works.

    This is a fantastic company to work with. The window they worked on was not easy. Other companies had refused to do it. The people of the Kelemer Brothers' Company were very personable, they did an excellent job, the window they installed was of the highest quality, my tenant was very happy, and the window has stood the test of time, as I am about 6 months late getting in this review. I felt very comfortable with the entire procedure, and I will definitely be using them again.

    From the beginning to the end of the process was an easy going. After going through crazy pressured sales men i was pleasantly surprised at the way I was treated by kelemer brothers. No haggling, great advice, and the experiance felt very personal which I liked. I purchased 14 windows and cant be more happy. I would definitely recommend to family and friends. I will be using them again for future jobs.

    Thank you so much for our new beautiful windows! I was so impressed by Gabriel stopping by at the end to see how everything was going, showed me different ways to use the windows, and brought flowers because it took longer than expected! Great customer service and we are loving our new windows
