Wooden windows and doors have been a staple design choice in all kinds of buildings throughout history. Their warmth and natural beauty are unmatched with other materials and, nowadays, the techniques used to design wooden windows and doors allows for them so be as low-maintenance and as energy efficient as possible. 

At Timbertherm, our speciality is in designing, constructing, restoring and enhancing timber windows and doors. We used engineered timber which is one of the most durable and low-maintenance woods on the market, designed not to twist or warp.

We work in a range of areas across London and the Southeast, including Upminster. 

Our key projects are bespoke requests, meaning that we’re experienced in creating a wide variety of designs and our step by step process involves working closely with you to get your perfect set of stunning timber windows and doors.

Firstly we’ll have a chat with you to discuss what you’re looking for in your ideal set of windows or doors — or both — and give you a few starting designs to choose from, taking measurements and giving you a quote. From there, we’ll be with you every step of the way, giving you options from the style to the colour, finish and any additional custom features. 

We use concealed security features in all of our windows and they come supplied with insurance compliant, lockable features as a standard. Our windows utilise high performing, Argon gas-filled, double glazed sealed units which improves their thermal-efficiency. 

Our work also involves the sympathetic restoration of period homes. If your home needs its windows or doors restored, we use conversation-approved wood and will work with your original designs to create exact restorations and can add some invisible enhancements using modern techniques, such as improved glazing for increased thermal efficiency.
