    Joe and his team were amazing. Joe guided us through the entire process and gave his professional advice on what made most sense for us. Joe even went out of his way to coordinate the install with our alarm contractor. The installers did a great job and made sure all of the debris was cleaned up.. Our new windows look great. We will definitely use Joe for future window and door projects.

    It was cold, rainy, snowy. The team came in - knew what they were doing, worked to try to keep us safe from broken glass and slipping on wet floors. They worked non-stop to finish on time. These guys know each other well and work like a well-oiled machine - incredibly professional. We thank the Kelemer Brothers for shlepping into Derwood to put good windows into our house -- always with a smile and a positive attitude - thanks.

    The windows are terrific, and better still the installation went smoothly and was done carefully and very skillfully. Awning style windows from 1957 required extra work to replace, and the Kelemer Brothers went the extra mile to maximize our new window glass area at a fair price. We recommend them highly.

    Our experience with Kelemer Brothers was excellent. When Gabriel came out to talk to us, he listened to our window needs and did not try to sell us something we did not need.The installation process went smoothly and we are totally satisfied with our new windows.

    Great service, great products. Will be using them again for future projects.

  • Fantastic experience from start to finish. It never felt like a pressured sales call but instead, they took the time to talk with us, identify our needs, and then work with our budget. The work itself is fantastic and we are very pleased with the end result. We had 14 windows replaced and they did the whole job efficiently and cleaned up everything afterward. We would highly recommend KELEMER BROTHERS to anyone.
