Dear Mr. Kypreous:
We are writing to express our thanks for the wonderful experience we had with your company.
We had all our windows and a door changed: 22 windows, 2 half moons, and a slider!

Bryan was a pleasure to deal with and very helpful all the way through. We live in a development
and needed a lot of paperwork prior to the job. Bryan came through every time.

Our installation crew, headed by Carlos, was terrific. Carlos, Carlos, and Jose were
perfectionists and we could not have asked for more, as we are perfectionists ourselves!

The windows are amazing. We can not believe how easy they are to operate and maintain. They
truly are beautiful.

I will highly recommend your company to all our family, friends, and everyone in our

Thank you for a job well done!

Sophie & Louis Sabat
