Top notch workmanship! They replaced all of the French doors on my Victorian property back in September. They did such a great job on that that I had them back out to replace some windows at the rear as well. They managed to fit it all in prior to Christmas as promised. Many thanks team Greenwood Joinery Ltd! Have a prosperous 2025!

Initially did a great job but one window had the glass put in wrong and has fogged up, they are supposed to be replacing it but now don’t answer the phone.

Frequently Asked Questions

Get answers to common questions about our wooden sash windows, from their customisation and installation to maintenance and heritage compliance.

uPVC stands for Unplasticised Polyvinyl Chloride. Also known simply as vinyl, it is a strong, durable, and long-lasting material commonly used in the construction industry. Thanks to its low-maintenance properties, uPVC is typically used for manufacturing windows, doors, and piping.

uPVC windows are expected to last at least 20 years, but with proper care and depending on various factors, they can often exceed this lifespan significantly.

uPVC windows are offered in a variety of colours, from the classic white finish to stylish options like Chartwell Green, and sleek, modern shades such as anthracite grey or black.

We provide a wide selection of colours and natural woodgrain finishes, ensuring there’s the perfect match for every property.

For a contemporary touch, consider dual-colour options, allowing you to complement both the interior and exterior of your home.

uPVC windows are accredited with PAS24 and Secured By Design, offering enhanced security.

Our casement windows come equipped with a multi-point locking system, which locks the window securely to the frame at multiple points, providing superior security over traditional locking mechanisms.

Shutters can be installed on uPVC windows just like on timber frames, as they are typically attached to the internal structure of the building rather than the window frames themselves. It’s recommended to use a specialist company to ensure proper clearances around handles and hinges, allowing for easy window operation and ventilation.

If you reside in a conservation area, it’s essential to consult your local planning office for any restrictions regarding window replacements. There may also be specific conditions in your property deeds.

In most cases, alterations to a building in a conservation area must be made with identical materials, including windows. For example, if your property currently has timber sash windows, you’ll likely need to replace them with timber sash windows.

As local planning offices may have varying rules, it’s always best to check with them to understand what changes are permitted.
