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.

Find out more about the range of timber windows and doors we manufacture.
Our timber entrance doors are all customised and made to measure. This means you can have whatever size you like.
All our timber entrance doors can be made to be inward or outward opening. This allows maximum flexibility if a restricted space opens into the room.
To meet exact application requirements, whether for residential or commercial use, we offer three locking systems. Standard, auto-locking and heritage systems. Pairing with electronic access control, including fob and magnetic card operation is also available.
Check out our ranges, and don’t forget to follow us on Pinterest and Instagram for more inspiration. Don’t forget, our front doors are customised to your requirements, if you want something a little different to what you see, contact us.
Timber doors do need some level of maintenance to ensure longevity, such as periodic refinishing or repainting, especially if exposed to harsh weather conditions. However, our modern timber treatments and finishes significantly reduce the need for frequent upkeep, making them easier to maintain.
We offer a range of customisation options, including different wood species, finishes, glazing, and hardware choices. This allows you to create a door that perfectly complements your home’s style and meets your specific requirements.
All our timber entrance doors come with a comprehensive warranty covering materials and workmanship. This gives you peace of mind knowing that your investment is protected.
This warranty includes coverage for issues related to manufacturing defects, ensuring the quality and longevity of your door. Additionally, we offer support for any maintenance needs under warranty guidelines, helping to maintain the door’s appearance and functionality over time.
Manufacturing times can vary depending on the design complexity and customisations, but we typically provide a timeline estimate once the order is confirmed. Our team will ensure that your delivery and installation are completed on time.
