Overall, good work but very expensive. We had 10 windows and two sliding doors replaced. Most work fine, but one of the sliders has never worked as it should. It is very tough to open. We were to led that the seal on the bottom would wear down and it would get better. It has gotten worse. For that kind of investment it should operate as advertised. I would not hire them again.
