French Windows cost in Cardiff
French windows (outward-opening paired casements to floor level) cost around 50–70% more than a standard casement due to the larger glass area and threshold detail.

| uPVC | Triple | £1,150 – £2,150 |

Cardiff note: Welsh labour rates sit below English averages; period-property scaffolding in Pontcanna adds a modest premium.
