Dear Mr. Egan
I am writing to you & your future customers. I have dealing with your firm for a few years always the best .
On my second floor i needed windows but Tri-State could not help me. My loss, because i went with Pella Corp. The first dealing went down hill & Five months later the situation still not resolved.
Every thing that Pella did was wrong. The Delivery was on a rainy day, So the installer could not work. The windows were left outside overnight.
If you ever need a recommendation as to the quality of work that Tri-State Windows does contact me. When comparing Pella to you guys there is NO comparison. Feel free to contact me anytime.
Sincerely
John J. M.
