Bradford-based Whitaker & Co, in partnership with CDS Housing, has just completed its largest-ever contract – supplying more than 5,000 replacement windows for 650 houses on an estate in Liverpool.

Made from Scandinavian redwood, the windows had to be manufactured in a variety of sizes – including one, two and three lights and bays – none of which were standard.

The windows from the company’s Cumbrian range were supplied fully finished and double glazed.
