Chepstow’s housing stock is unusually mixed: Georgian and Victorian stone in the town centre and Conservation Area, post-war brick out toward Bulwark and Tutshill, and modern timber-frame estates in Sedbury, Crick, and the Caldicot fringe. Each demands a different replacement glazing approach — slim double-glazed units (10–14 mm cavity) for heritage frames where the original sightlines must be preserved, standard 28 mm units (argon fill available as an upgrade) for modern uPVC and aluminium, and triple-glazed specifications for new-builds chasing Welsh Government Approved Document L (the Welsh equivalent of Building Regs Part L).
We have been supplying replacement sealed units across the Bristol catchment for 25+ years, and Chepstow is a short drive over the M48. Our fitting and repair service covers Bristol, Bath, North Somerset and South Gloucestershire, so in Chepstow we supply made-to-measure units for you or your installer to fit. Every unit is made to BS EN 1279 by our partner factory and comes with a 10-year guarantee (original buyer only).
For Conservation Area work in the Wye Valley AONB, we supply slim double-glazed units that fit original timber sashes and casements without disturbing the sightline. For new-build retrofits chasing Passive House U-values, we supply triple-glazed units with argon or krypton fill (see the comparison).
