Dear Tri-State:

 

We love our new windows. With the extreme cold this week, it was easy to tell that the house was much warmer. Additionally, you promised us that we would have the best installers, well you were correct again.

 

Not only were they fast and precise, but they left our home just as clean as they found it. John was home with them on Tuesday and told me that they cleaned up as soon as they finished each room. We truly never believed that they would be able to install 16 windows in one day. The office told us that they would be at our home between 9 and 10a.m. John was delighted when they arrived at 8:15, we have never had such great service.

 

Again thank you, and I would not hesitate to recommend your firm and particularly your installers to anyone.

 

Sincerely,

Lois & John
