UPVC windows for ex-council semis across Cardiff

Every ex-council semi in Cardiff has its own quirks, but the recurring six are: cavity brick or block construction with a rendered upper storey; generous garden front and back — often the largest plots on the street; large square window openings, originally metal-frame Crittall or timber casement; along with the usual post-war-property reveal detail. When uPVC windows land on this spec, we default to A+ rated multi-chamber uPVC, white, anthracite grey, black, foiled woodgrains. Rear outshut kitchens often have flat felt roofs at 2.1m — glass and frame heights are set to clear the eaves. Tile porches are laid on a lime bed that reacts poorly to modern silicone; we mask and use low-modulus polymer instead. Salt spray in high winds reaches inland elevations at coastal properties — we spec stainless furniture on rear frames too. Original patio door tracks sit direct on the floor slab — we lift, level and re-set on stainless packers. 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. Alley access at the rear is barely wide enough for a single pane of 1200x900 glass — we plan lift paths around it. Front door threshold sits on a York stone step in most cases — level it back to the tile line before the frame lands. Non-square reveals mean every frame is bespoke-scribed — templates rather than standard sizes.
