Composite doors for 1960s new-town homes across Pontypridd

1960s new-town homes on Pontypridd's long rows of valley terraces with stone fronts streets share a specific set of quirks. Timber-frame walls mean the frame fixes to studs, not to masonry — survey before ordering long fixings. New-town estates are rarely restricted at the front-door level, though large glazing swaps sometimes need building regs sign-off for structural loading. Old frame stripped on the day, new outer frame fitted plumb to the brick reveal, threshold sealed with EPDM and silicone. Oil-heating running costs make triple-glazing an easier upsell on barn conversions than on urban stock. Render around the frame edge is often 60s scratch-coat — patch and re-paint the same visit rather than mask. The porch canopy fixings are usually one bolt into masonry and one into the fascia — we test both before removing the old door. Fitted in a single day, usually 4–6 hours. External timber cladding at the head of the window is easily matched to modern PVC trim in a coordinated foil. Developer window frames are typically low-spec multi-chamber uPVC — the profile is fine, the hinges and glass are the fail point. The load path through the bay corner post pulls diagonally when the roof sags; reinforced steel accepts it, aluminium alone deflects. Gravel front gardens mean the crew boards from the van to the elevation to avoid tracking stones inside. 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.
