in general, I think I will be very happy with the Indows, and your service all around was really great! I would suggest that you find a different shipper than Tforce; I’d had problems with them before, both in adding cost after the shipment, not calling as promised before delivery, and in general feeling very uncomfortable with them. My installer noticed a small nick but it must have been limited to the plastic covering because I don't see it. But that’s my only beef about the services we received; your response was quick, efficient, and tailored to us. My beefs are that my Indows did NOT need the safety seals! In fact with the mullions the other end couldn’t even be installed. So we cut off the chains. But 3 of the 5 Indows are on windows that do not open! And, on the other 2, I won’t be able to use them since they open out and up, and my windows open sliding up from the bottom. So extra work for the installation and they won’t be used. Also my installers mis-read the instructions and washed my Indows with the solution, but they are carpenters not window washers! I would have liked separate, printed directions for the homeowners that explain the Indow washing needs and process. They do seem to make a difference as far as drafts, though I’ll need to wait til next winter to see how much! Also, and this surprised me because I just got regular, not noise-reducing ones, is that they do reduce the noise! Thanks so much!
