"Nikiya came to my home to help me choose windows to replace old windows that are leaking cold air in winter. With the price of oil this year, it is worth the money to do this work. His presentation was very well done, with demonstrations that help me to choose the windows for our home. Nikiya was friendly and extremely knowledgeable about his products, and I appreciate that."
