Our timber single or back doors come in a range of different styles and designs. They are often simpler than our entrance doors, with an understated aesthetic. They also usually feature more glass than our entrance doors which allows extra light into utility areas and kitchens. Our timber back doors can be made to open inwards or outwards. If space is a premium inside, it can be beneficial to have the door opening outwards.
When it comes to security, our back doors can’t be beaten. They meet the requirements of PAS-24 and are Secured by Design. With multi-point locking, cylinder locks and a choice of standard or auto locking. With only one handle located on the internal facing side for the auto-locking system, the multi-point locks are automatically triggered when the door is shut which means this system is perfect for those timber back doors that open onto a public or communal area.

Single timber doors can be customised to fit non-standard openings. If you’re looking for a traditional timber back door, George Barnsdale offers made-to-measure solutions to make for a perfect fit.
Our doors meet UK standard dimensions while allowing for flexibility in design, finish, and configuration to suit your specific requirements.
Yes, timber front doors can be designed to open outwards, depending on your specific requirements and the layout of your property.

If you’re considering a timber back door, our bespoke options allow you to tailor the opening direction to suit your needs.
We understand that ensuring the safety of your property is one of the most important aspects of property ownership, giving you peace of mind. This is why we offer multi-locking systems, smart locks and mortise locks to suit your preferences.
We also make sure all products we sell are up-to-date with current security standards in place.
