Composite Front Doors on a valley stone terrace in Cardiff

If you've got a Welsh valley stone terrace on your hands in Cardiff, the recurring problem when quoting composite doors is single-skin stone means condensation and cold radiating off the internal reveals. Old timber and rotten 90s uPVC front doors that leak heat, jam in winter and fail break-in standards is the paired issue you'll usually hear about at the same visit. Our spec here is 48mm solid composite slab with GRP weatherproof skin. Post-war doors sat on a raised timber threshold; a Part-M part-plate replaces it cleanly at composite door install. Stone cills usually project only 40mm — the frame drip has to clear the projection without over-hanging. Sash cord pulleys behind the timber lining come out clean if the paint layers haven't fused them to the box. Wind-driven rain finds sealant gaps that inland elevations tolerate — bead depth matters more than usual. Bay window scaffold requires a chimney tie or through-bolt to the party wall — allow an extra hour on set-up. Estate covenants are searchable through the deed pack; we ask the client to confirm colour before ordering foil. Stone reveals need resin anchors, not plug-and-screw — dressed stone crumbles under mechanical fixings. Door head heights sometimes below 1.9m; a standard 1981mm slab needs trimming or a bespoke height ordering. Tile porches are laid on a lime bed that reacts poorly to modern silicone; we mask and use low-modulus polymer instead. Rear outshut kitchens often have flat felt roofs at 2.1m — glass and frame heights are set to clear the eaves.
