How do I get trade prices for County Down?
Request a quote with your sizes and postcode. Trade pricing applies once your account is open.
Why are sliding sash windows dearer than casements?
They use more profile, balances and hardware, and every window is set up individually. Our guide range reflects that.
Can you match the glazing bar pattern of existing windows?
Yes. Tell us the pattern for each sash, for example six over six or two over two, and whether you want bars that look applied or sit between the panes.
