A plain door or flat door panel will take around 45 minutes to an hour, with profiled and panelled doors adding about 30 minutes to that. Microchip cat flaps in metal skinned doors take about 2 hours. Glass requires two visits of 10 to 15 minutes to measure, and then generally around an hour to fit when the glass has been manufactured (see seperate FAQ). A wall takes around 3 hours from arrival to completion
