Great Harwood Windows - Serving Lancashire and the North West UK

Established in 1990 by our Managing Director Jimmy Hindle, Great Harwood Windows was originally located in Great Harwood itself before increasing our ambitions and workforce to eventually relocate to Blackburn. Since then, we’ve built up a reputation as being one of East Lancashire’s most trusted and reliable home improvement companies amongst both installers and homeowners.

2005 saw the business expand once again, moving to much larger premises with more factory and office space in order to cater for the high demand we were experiencing. Despite our size, Great Harwood Windows remains family run and remains committed to providing customers with a hassle-free, personable service built on a long standing reputation that you won’t find anywhere else.
