"We ran our air conditioner for the first time this summer and it literally cycled half as much as it usually did.
That is a great improvement. Thanks again for all your help."

- C.A., Mt. Prospect, IL 60056

"We wanted to thank you and your crew again for the high-quality job that was done on all of our new windows and doors! Our house just turned 50 years old and it still had most of all of its original windows. It is quite a difference with the new ones. No more peeling and cracking paint! No windows that are sealed shut! No more changing out the outer storm windows for the summertime screens! And most-importantly, no more drafts and excessive heat exchanges! We ran our air conditioner for the first time this summer and it literally cycled half as mush as it normally does. That was a great improvement! I'll expect the same results this winter. The bow window is the kitchen actually lets in more light than the flat window that used to be there. Which is ideal for a north-face window. The new doors look great too and provide a much-needed seal as compared to the old aluminum doors. The crew was great! They did a 2-day job in less than a day and cleaned up very well. The walk-through went well too. Thanks again for all for your help. I'll highly recommend your company to anyone who needs replacements like I have."

Sincerely, Chris A., Mt. Prospect, IL 60056
