Professional curtain wall replacement across Derry and County Londonderry — free surveys and fixed written quotations.
We are Derry's curtain walling specialists. Whether you need curtain wall replacement for a new build, a refurbishment or an urgent repair, our County Londonderry installation teams deliver CWCT-standard work with full certification.
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.
Derry sits within our core County Londonderry coverage area, which means fast survey appointments, realistic lead times and an installation team that can return quickly for snagging or future phases.
Every project starts with a free, no-obligation site survey and a fixed written quotation — no estimates that drift.
