Dear Gary
Your workers finished installing the 18 windows in our house yesterday, January 7, 2011. The workers, Gus, and I believe Emilio, did an excellent job. They worked very hard, only taking a 15 minute break for lunch, and cleaned up everything. They were fantastic, and so are the windows.

The windows look beautiful and already we notice there\\\'s no breeze coming along the sides and the house heats up quicker than usual. We especially like the sliding glass door. Now we can enjoy our deck like we wanted

Thank you very much
Yours Truly

Ray and Rosanne G
