Wooden Window Frames, Repair & Replacements

Traditional Wooden Window Frames

Our skilled craftsmen create custom wooden windows tailored to your home’s style and insulation needs. Each window is hand crafted using sustainably sourced materials and traditional techniques.

Wooden Window Frame Repair

Wooden window frames most often rot at the point where the vertical section, called the mullion, meets the sill. Mullions divide windows vertically and can be purely decorative or provide structural support. Their horizontal counterpart is called a transom. Both transoms and mullions are prone to rot where they join at the sill, but in many cases these areas can be repaired without replacing the entire frame.

Water is usually the main cause of this damage, often entering through the glazing (leaded window or single piece of glass) and soaking into the wood frame. Condensation is another common culprit.

Traditional wooden windows, particularly those made before 1919, can be repaired easily and cost-effectively. Due to the fact that older timber was generally of much higher quality and more durable than the wood commonly used today.

Whilst rotten wooden window frame repair can be executed, this is only feasible if the frame is still structurally sound. If rot has completely destroyed the joint where the mullion joins the sill, patching it is often a time-consuming, labour-intensive short-term fix rather than a lasting solution.

Replacement Wooden Windows

We offer complete wooden window replacements that match your original frame perfectly. This is often the most cost-effective solution, where we use sustainably sourced wood that is guaranteed not to rot for 60 years and will only need repainting every 10 years.

We also provide wooden replacement windows for listed buildings. In many cases, formal permissions are not required, as the work is considered ‘like-for-like’ repair and maintenance, which listing authorities encourage to preserve the building.

Glazing Timber Windows

Whether the frame is metal or timber, the approach to re-glazing is very similar. The rebate is cleaned, and a thin coat of primer is applied before new linseed-oil putty is applied to the wooden windows. The glass pane can then be pressed into place and fastened with fixings that replicate traditional window glazing methods.
