Attn: John Kypreos

 

Dear John,

 

I wanted to take a moment to send you this letter regarding the work I contracted with you to be done in my home. First and foremost thank you for all your outstanding services and professionalism. When I first came to your factory in Deer Park in October 2009, I was interested in purchasing windows for my home. I was hesitant to commit to such a large purchase. I was impressed by your factory, staff and  yourself. You took the time and patience to give me a tour of your state of the art factory and explain how the equipment works. Not only  was iI impressed, but I was made to feel completely at ease. You successfully overcame any reservations I had with purchasing the 20 windows from  your company. As promised the work was completed as scheduled. The workers were neat,  professional and courteous. A job well done!

 

In June 2010, I was considering refurbishing my home once again with roofing and siding. I again visited your showroom with the intention of getting an estimate. Again, you took the time to explain and answer all my question regarding such a large undertaking. You didn\'t rush me when I was choosing the siding and roofing. You made my decision stress free and pleasant. We agreed on a scheduled start date, and as before the work was started as promised. The roofing was completed including impeccable clean up within one day. The following day the siding was started and completed within five days, without any inconvenience to my family. The last phase of the job was the gutters, which was completed within the same excellence as all the other work. Every worker was professional, pleasant and patient. My home is now the showplace of our neighborhood.

 

In closing I must say Tri-State Window factory far execs any other home improvement company I have ever done business with. I am from the school of thought that a good company and a good job deserves to be recognized. I plan on spreading the word what a great reliable company you have.

 

 

Sincerely Richard D
