Mike Rood on KobyCo Door & Window

I am overall very happy with KobyCo. It was a long wait for our doors and I still think they were very expensive, but, the installers did a great job. The doors are tight and work well. They look outstanding! They are very solid and well constructed. Well pleased.

Sharon McGraw on KobyCo Door & Window

We decided it was time to replace our windows as they were single pane originals when the house was built, and in bad shape. We got three quotes and decided on KobyCo. When we met with Mike we were impressed by his vast experience and knowledge. Mike showed us a sample of their window construction and we were impressed with the high quality (double pane). The installation crew showed up as promised and were extremely professional and accommodating to ensure we were happy with their service. We would highly recommend KobyCo!

Thank you Kobyco! I am pleased with the results of my replacement windows. From the estimate to install everything was seamless. Shout out to Carrie in the office for her flexible scheduling and shout out to Jason and his team. Jason's team was punctual , professional and detailed. I will not hesitate to use Kobyco again.

Melissa B on KobyCo Door & Window

Our whole experience with KobyCo was seamless. From the moment we walked into the showroom Mike Martin was knowledgeable and helpful. The window we were replacing was a special order and Mike was upfront that it would take time to come in and once it was ready, the installation was quick and easy. The employees were on time and respectful of our property. We have had the window installed in July 2025 and have not had any issues. I will certainly consider KobyCo in the future for additional window replacements.

Gordon Neese on KobyCo Door & Window

Our expanded house includes the original1846 limestone farm house and the 1990 installed Marvin double hung windows - 2 upstairs and 4 downstairs - were rotting out. KobyCo replaced them with hugely functional and attractive double hung thermo-pane windows in one day at an incredibly reasonable price. The cleanup was meticulous and the windows' trim work - both inside and outside - look outstanding. KobyCo was incredibly professional from beginning to end; installation scheduler Kari was especially helpful. I couldn't be more pleased with KobyCo and highly recommend them; 5 stars doesn't seem like enough.
