Thank you for doing such a wonderful job on April 30, 2009.  The windows are perfect.  They really make the house look fantastic.  Mark and his crew did a magnificent job.  They cleaned up everything.  The entire house was completely done by 4:30pm.  They did the job quick and quietly that our 3 month old did not even cry.  We were very impressed and recommend Tri-State Window Factory.

 

Sincerely,

 

Mr. & Mrs.  E.
