Cardiff specifics
Housing: Pontcanna and Canton Victorian terraces plus Cathays student housing define the window market; bay windows are standard on Edwardian semis.
Climate: Sheltered by the Brecon Beacons but exposed to Bristol Channel gales; coastal properties in Penarth need marine-grade hardware.
Price driver: Welsh labour rates sit below English averages; period-property scaffolding in Pontcanna adds a modest premium.
