Customer Reviews

Pulkit Saxena

We had a great experience with Kelemer Bros Windows from start to finish. Joe Kelemer was fantastic to work with—clear, responsive, and easy to communicate with throughout the entire process. He was never pushy, took the time to answer all of our questions, and offered very reasonable pricing compared to other quotes we received. The installation itself was quick and smooth, and the crew did a great job. The windows and sliding door have been functioning perfectly since installation, and the sealing was done very well—everything feels solid, tight, and high quality. Overall, a very professional experience, and we wouldn’t hesitate to recommend Kelemer Bros to anyone looking for new windows.

I have worked with Kelemer Brothers twice to replace all first and second floor windows and both exterior doors. Their products and service are of the absolute highest quality. Joe makes every step of the process a pleasure. He explains the products and the process thoroughly, and patiently and cheerfully answers all questions. The crew is professional and goes the extra mile, great attention to details. Highly recommend.

I hired The Kelemer Brothers for a windows replacement job on my home. I worked with Joe, and I have to say that his service was impeccable. Full white glove service. I reached out to several companies for quotes to replace 12 widows. The quote I received from Joe was significantly lower than the other quotes. And the windows that Joe recommended were of a better quality. Joe's passion and energy for his work hits you from your first interaction and continues throughout the entire project. The entire process was seamless. On the initial call I told Joe what my needs were and he set up an in person consultation. I was impressed with what his company had to offer. And his integrity of standing by his work (and word). The team that installed the windows were professional, punctual, perfectionist and personable. The day of the job they were able to arrive earlier than scheduled and completed the work by 2:00 PM. All 12 windows were installed and everything (the old windows and materials) was cleaned up. Joe then came by to inspect the work with me. I am 100% pleased with the work. And would recommend The Kelemer Brothers to anyone that has a windows replacement job and is looking for a contractor.

This is our third, yes, third time hiring Kelemer Brothers to replace windows at our primary residence, and every time has been an outstanding experience. Joe took time to listen to our needs, personally arrived few times to ensure the work was done right, and even came in to do a final walkthrough when the job was completed. A huge thanks to the crew who competed the job in just about 5 hours to replace 12 windows in our home. The lace was left as clean as prior to installation which is greatly appreciated. We have already noticed better noise cancellation, insulation, and lower levels of humidity - thanks to the new high quality windows installed with high level of professionalism and dedication. Thank you, Joe, and all team members for the job well done! Wishing you continuous success!

From start to finish, my experience with Kelemer Brothers was nothing short of excellent. The entire process was smooth, pressure-free, and professional. At no point did I feel like I was being upsold or pushed into upgrades I didn’t need. Joe, the owner, personally took the time to walk me through the different options and explained the features of the windows in detail. His knowledge and transparency made me feel completely comfortable with my decision. When it came time for installation, the team was incredibly efficient and neat. They respected my home, worked quickly, and left no mess behind. I was truly impressed by their attention to detail and the care they took throughout the process. Even after the windows were installed, Joe took the time to walk me through how to operate and maintain them properly — a rare level of service that speaks volumes about their commitment to customer satisfaction. If you’re looking for quality windows and an honest, dependable company, I highly recommend Kelemer Brothers. You won’t be disappointed!
