My experience with KC (Installment Serviceman) was awesome. Very professional and made sure he tackle the hardwork head on. I know his job wasn't easy because this was the only company we could find to replace mobile home windows. KC never showed any frustration on his part. He remained kind, respectful, explained and demonstrated the operation of the types of windows we purchased. So, if I had the opportunity to rate 10 stars, I would for the salesmen, KC and the company as a whole. Thanks for the overall exceptional service!
