How to Use Wood Fillers to Repair Timber Windows
Many timber windows are affected by rot, which can cause a range of issues, including peeling paint, windows that stick and rattle. Repairs that are done with care can keep your historic windows in good shape and increase their energy efficiency in the process.
The first step is to determine the extent of the rot. This can be done by probing into the wood with an instrument with a sharp edge and checking the windows for damp areas, sunken corners, and sagging wood.
Wood Fillers
Wood fillers are a great method of sealing cracks and crevices within old wooden windows. They are usually made from sawdust or other wood shavings that are suspended in a water or petroleum base. They can be used to repair rotting or damaged timber window sills, frames and sash windows. They can be tinted to match the color of the existing timber, then sanded, and finally stained or painted. However, it is important to choose the right kind of filler for your needs. This guide will help you choose the best one for your project.

The next step is to determine the root of the rot. If the wood is unstable due to a lack support, you will need to treat it with a structural stabilizer. This will stabilize the wood and can be applied with paintbrushes or other similar tools. Once this has been completed the wood can be treated using a water-based wood filler like Bondo(r). Water-based wood-fillers tend to dry faster than solvent-based ones, and are easier to remove, since they don't require acetone.
Use standard latex sealant made of acrylic to fill in the gaps between wall openings. It's a good choice and is easy to apply and will accept all paints. However, it is worth checking the frame for rot before applying this method, since too much sanding can make the gap too wide and the window susceptible to leaks.
The final alternative is to use an epoxy filler that is heavy-duty. This type of epoxy filler is created to endure extreme temperatures, humidity, moisture, and heat. This product can be sanded and carved when it is hard, which gives you greater control over the final result. However, it is important to remember that this type of filler absorbs stain differently than natural wood, and it is unlikely that an exact shade match can be achieved.

It is essential to remove all emulsion from the splice and avoid applying too much film cement, which could cause it to leak and damage the lining. Once the splice is completed, it is recommended to tape one edge to hold the repair in place, and then apply the cement to the film working from the centre outward, (fig 11.1 iv).
To stop further deterioration from occurring To prevent further deterioration, it is recommended to seal all of the repaired areas with a damp prevention treatment compound.
