KELEMER BROTHERS REPLACEMENT WINDOWS REVIEWS

We have known and used the Kelemer Brothers for many years, and have recommended them to so many of our friends and family over that time. They replaced windows and doors at our daughter's home, and worked on various projects for us including replacing windows in our own home. They have excellent crews, great products and reasonable prices, and they pride themselves on their honest appraisals of the job at hand.

Kelemer Brothers was recommended by a friend, they explained the process of getting new windows and I felt no pressure. It was a joy working with them.They replace my windows, cleared and cleaned up all debris. I have 3 windows I still need to get, and look forward to work with them again.

A friend recommended Kelemer Brothers. Gabriel was friendly and easy to work with. No sales pitch or pressure, painless from start to finish. The crew did a fantastic job and were very polite and considerate. Highly recommend.

WINDOW NATION REVIEWS

Good service, I was kept informed on the progress. Did get notification on scheduling for installation though. The installation team was super! Did great job, we’re on time, polite, thorough; checked out the final product, demonstrated how to operate, cleaned up nicely after their work was done.

Nowell was great and very informative. I ordered five windows from him. He is full of energy and really knows a lot about Windows.

Grace was very professional and friendly! Highly recommend Grace.

WEATHERMASTER WINDOWS REVIEWS

The process was very easy. The company kept us up to date on everything. We had 11 windows installed in one day. Installers were positively fantastic. While one was finishing up the other one rehung all our blinds. This was above and beyond and greatly appreciated by older customers. This was our second project with this company and after several estimates we made the right decision again.

I had an excellent experience with WeatherMaster Windows from start to finish! The process began with an on-time estimate and a fair price for high-quality windows. The second step, the final measurement, was also quick and efficient. Next, I appreciated that the windows arrived exactly when I was told they would. The installation, which involved 18 windows, was completed in just two days with minimal disruption to my household. The installers did a fantastic job, and since the windows were installed, I've noticed an immediate improvement in heat retention and a significant reduction in outside noise. Overall, I'm extremely satisfied with the entire experience.

Technician came on time. Weather was not good for doing the replacement pane so we decided to do it another day. On rescheduled date the technician was again within the allotted time. Was very satisfied with the service. He also gave me a suggestion on how to make the windows slide better as after time they can tend to slide a little harder. We also went over again how to open to clean. He always answered my questions.
