Covid 19 update 9th December 2021

Following the latest COVID 19 update regarding Government restrictions, Epwin Group will continue to operate with current on-site safety measures in place for the foreseeable future.

Our main priority is to ensure the health and safety of our employees as well as those of our customers and suppliers during the continuing pandemic in order to best support our customers and maintain the wider industry supply chain.

We encourage all colleagues, customers and suppliers to fully observe all of our recommended on-site safe operating procedures, in particular, the appropriate wearing of masks, suitable social distancing and regular hand washing. We also encourage everyone to take sensible steps outside of work to keep themselves and their work colleagues as safe as possible.

If you have any queries please contact us: 0808 178 3455 or email sales@sierrawindows.co.uk


At Sierra Windows, we’ve been creating bespoke frames from our factory in Devon since 1976. Today, we combine good old-fashioned customer service with new and innovative solutions that have the power to transform homes and workplaces.

You can leave it with us. By choosing Sierra Windows, you’ll have access to a wide range of suppliers, many of whom will only work with larger businesses like ours. This enables us to offer everything you need under one roof. Each frame is crafted to order right here in Devon, and nothing leaves the factory floor until it meets our exacting standards.

We’ve obtained a wealth of experience during our forty years in the business and we’re happy to share that knowledge with you. Whether it’s a question about measurements, some advice on styles or a few fitting tips, talk to a Sierra Windows expert today.
