"They did an excellent job and I highly recommend them for window replacement work. Gary Chern provided a very clear presentation of the company and the windows they offer with various options. Larry Khimich was very communicative with the details of the scope of work and their crew did an excellent job. They damaged one lawn decoration that we discovered later and they provided payment for replacement of the decoration. Mistakes happen and they made good on the damage. They did the work in October and it is now the end of March. No problems and we are very happy with our new windows!"
