Questions homeowners & self-builders ask

Do you cover self-builds and retrofits across all 26 counties?

Yes. Enquiries from any of the 26 counties go to one vetted alu-clad window specialist covering your county for a window-schedule take-off or on-site survey.

Why are coastal counties so popular for alu-clad windows?

Because extruded powder-coated aluminium cladding (with Qualicoat Seaside marine pre-treatment) completely shields the structural timber frame from Atlantic salt spray and driving rain while keeping real wood warmth indoors.
