About Sierra Windows

We’re a UK-based company specialising in made-to-order windows, doors and conservatories, and we’ve earned a reputation for delivering on our promises. Thanks to the comprehensive expertise of our craftsmen and the support of our knowledgeable customer services team, we’ve become a trusted partner to the businesses we work with.

But we don’t rest on our laurels. We’re staying ahead with new and ingenious energy saving techniques, we’ve just introduced new foils and finishes to meet the requirements of modern builds, and we’re introducing new technologies and processes, so that we can continue to deliver the most efficient service possible for our customers.

We’re proud to be part of the Epwin Group, a network of like-minded companies, which enables us to secure investment, continue to innovate and meet the high standards our customers expect from us.
