Period-property casement windows in Caerphilly

If you've got a period stone cottage on your hands in Caerphilly, the recurring problem when quoting casement windows is reveals are non-square — every opening is a bespoke measure. Sticky old aluminium or timber casements that whistle in wind and won't hold open against a breeze is the paired issue you'll usually hear about at the same visit. Our spec here is chamfered or sculptured 70mm uPVC profile with friction stay hinges with restrictors. 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. Hardware fails on schedule at year 8–10; upgrading hinges alone during a full re-glaze extends the frame life a decade. Original oak lintels can be scored and treated, not replaced, when they sit sound above a new frame. Sash pockets in the original box are often stuffed with newspaper insulation — worth checking dates for interest but binning safely. Cavity insulation was retrofit-installed on most 30s semis in the 2010s — check for bead migration at the head before the new frame lands. New-build reveals are square to within 3mm — packing is minimal and the frame lands true first time. Roof canopies are usually mono-pitch and shallow — scaffold clearance rarely exceeds 2.1m above the frame head.
