We bought 8 windows 1 picture window with 2 side windows attached & a patio door from Alside, they contracted with Quality Contractors to install the windows and door. I complained right away about the wind coming in around the windows and frost on double pane insulated windows the changed all the bottom pains on the double hung windows. I still had air coming in around windows. They sent a man to do more caulking. There was still air coming around the windows. I hired a person that does energy audit and a private contractor to check the installation of the windows out . They both concluded that it was a very poor install on the windows. This year I complained again and they did not respond. We were going to have the house insulated and newsiding put on. I wanted them to look at them at this time to see if they would redo the windows the right way they sent a man to look and do more caulking. The only place he could do any caulking was on the inside around the casing's. I have hired the contractor that is doing the siding to do the windows the right way. If anyone thinks of having Alside or Quality Contractors do any windows or doors they better rethink and hire someone that is local to them. Patsy
