We checked out 3 or 4 companies to install our windows but decided to "go local" because Cayman windows had been in business for many years and backed their windows with a lifetime warranty on everything. They began to install the 6 windows we purchased within 4 weeks of our order, started at about 9am and finished by 3pm. They cleaned up afterwards and we are thrilled with their product. When we asked for an adjustment on 3 of the window locking mechanisms to make it easier for my wife to open the windows, they jumped into action and tailor-made a solution without additional charge. I was also able to tap into a "Frugal Friday" discount through our local paper which reduced the $7000 cost. I'm more than happy with the results.
