Welcome to Per-Fit Windows Commercial Ltd. Per-Fit Windows was established in 1982 by Mr. Andrew Barton and Mr. John Smithies, based in a 500sq ft unit in Heywood Lancs. Mr Barton and Mr Smithies who came from Upvc manufacturing and a glazing background did everything from selling, surveying, manufacturing and fitting with just themselves and a staff of two. Over the years they have seen the company grow into one of the North West biggest Upvc window and conservatory manufacturers supplying products to most of the major regeneration programmes, employing and keeping in work over 140 people. Per-Fit Windows is now a 6 million pound turnover company and is based in a 24,000 sq ft purpose built production factory with a major investment into modern computerised machinery in order to take the company forward.
