Nothing but problems. First attempt - door scraped the carpet. Second attempt - trickle vent fitted incorrectly so would not seal and top of frame bowed such that the doors did not seal oh and lock fixing screw had split the thermal break. Straightening of the frame resulted in a large hole in plaster requiring replacement of plaster board and plaster plus redecoration. Am still waiting for supplier to contact me to see if repair was satisfactory and to send in finisher to remove a stain on the frame. I have not been offered compensation for the hassle. I realise that these problems were not of Origin's making but they reflect on the manufacturer. Otherwise; the door is good and we are very pleased with the outcome.
