Caerphilly new-build estate home composite doors — Rosac survey & install

Owners fixing a handful of failed units or a warped front door, or upgrading the whole set from developer-grade to installer-grade. That's the search intent behind most new-build estate home enquiries for composite doors out of Caerphilly. A replacement composite in the same colour family as the estate spec keeps the covenant happy while stepping up the slab core and lock. We stock Anthracite, Chartwell and Slate to match the majority developer palettes. Where the original glazing bars were 22mm ovolo, we match printed bars to that width — not the modern 26mm default. Seafront elevations often benefit from a rain deflector bar over the composite door letter plate — standard spec here. The rear garden extension pattern (added 80s–00s) usually holds the tired patio door — replace it as part of the same job. Wind-driven rain finds sealant gaps that inland elevations tolerate — bead depth matters more than usual. Sash cord pulleys behind the timber lining come out clean if the paint layers haven't fused them to the box. Stone cills usually project only 40mm — the frame drip has to clear the projection without over-hanging. Post-war doors sat on a raised timber threshold; a Part-M part-plate replaces it cleanly at composite door install. Gravel front gardens mean the crew boards from the van to the elevation to avoid tracking stones inside. The load path through the bay corner post pulls diagonally when the roof sags; reinforced steel accepts it, aluminium alone deflects.
