Need curtain wall replacement in Caernarfon? We install thermally efficient, fully certified curtain walling systems across Gwynedd, backed by manufacturer warranties and CWCT-compliant installation records.

Curtain walls from the 70s, 80s and 90s frequently suffer failed seals, cold bridging, misted units and corroded fixings. Full replacement with a modern thermally broken system transforms both energy performance and appearance.

We specialise in replacement on occupied buildings — phased elevation-by-elevation programmes, temporary weather protection and out-of-hours working keep the building in use throughout.

Replacement projects include full structural survey of existing fixings and slab edges, so the new system is engineered to the building as it actually is.

From Caernarfon town centre commercial frontages to business park offices on the edge of Gwynedd, our teams handle the full range of curtain walling work with the same survey-first, certify-everything approach.
