I have POA over my grandparents and I was worried about them being ?taken? since I was not able to be there for installation. What a terrific experience! Not only were the installers pleasant and kind to my grandfather (who is hard of hearing) but they went above and beyond to explain things until he understood them. The quality of the work and windows is outstanding and so was the customer service. And they didn?t just do the job and leave ? they have followed-up several times to make sure we are still happy with our purchase.
