Attention: Mr. Paul Klemm

Dear Mr. Klemm,
Just wanted to write to let you know how pleased we are with your company\'s
product. We had 7 double hung windows installed and were very impressed not
only with the quality of the windows but also the installation.
We shopped around before calling your company and the quality of your product
could not be beat. We had one company provide us with an estimate for
approximately the same price. They seemed to have good windows but not close
to the quality and construction of your windows. I even considered installing my
own windows, but after considering how little I would be saving with windows of
less quality, it just wasn\'t worth it. The crew that did the installation were very
professional and did an excellent job.
Thank you for answering any questions we had in full detail and for promptly
returning any phone calls, even after installation was complete. I would very
highly recommend your company\'s product.
Very truly yours, &o
Joseph A.O.
