Welcome to BWM Windows

For over 30-years, we have been leading glazing specialists in Wales and South West England. Since we opened in 1991, we have been committed to creating quality windows, doors and other home improvements, in a conscientious way. With over 40 local people in our team and over 80% of our suppliers being South Wales companies, it’s safe to say we are backing local industry. Our care isn’t limited to Wales either, our products are fabricated using recycled energy and our premises are heated through green energy sources.

Perfection is always our goal, which is why everyone in our team works to reach the highest accreditations and standards. We are accredited fabricators and installers for most of our aluminium products. Our entire product range is also created using the highest quality materials. We are also registered with Certass. As part of our aim to be the very best we can be, we also carry out CPD training for all of our employees on a yearly basis. When you choose BWM Windows, you can have full confidence that we are experts in our field.
