Overall I am thrilled with the windows - and especially the new front door. A new patio door as well (much better than the Anderson patio door on the lower level that was not replaced). The style of the windows - double hung & slider - versus the old casement / crank out are a big improvement! Now on a breezy day the windows can be open without worry of banging back and forth. There were a few glitches along the way, but the company was always ready to stand behind the product and determined to make everything right. Custom work had to be done on two basement windows (window well) to adapt to a slanting sill to allow as much light into the rooms as possible. This was greatly appreciated, as other options could have been done that would have been easier. Mike, the service tech was extremely concerned that I was happy and satisfied with the work of the company and yes, I am.
