This patio door is a thorn in my side.
The screen door part is forever falling off the tracks and getting stuck. Then shortly after listing our house for sale the one glass side fogs up. Of course that is one of the things the buyers want fixed before they move in. We thought it would be an easy fix and not too expensive. Of course not. I will spare you the ridiculous details but we finally found a company who was willing to take on the job and for a reasonable price.
