Is it better to repair or replace my timber windows?

Timber windows add style, character, and elegance to your property. If you have a period property, they’re the obvious choice, and wood windows are also the most environmentally friendly option.

Timber windows do require some basic maintenance to keep them looking their best. Whether you have wooden sash windows or wooden double-glazed windows, ensuring they’re correctly maintained will mean you can enjoy them for years to come.

If you’ve bought a house with existing timber windows which are in a poor state of repair, you may be wondering if it’s better to repair or replace them. Let’s explore the options.

When to repair or replace your timber windows

Firstly, take a good look at your windows to assess their overall condition. Frames are exposed to a wide range of weather conditions, and this causes paints to deteriorate over time. Loose paint should be removed, and the wood sanded before repainting. This will also allow you to see if the wood underneath is in good condition. You can give your timber windows a new lease of life with a repaint if it is.

If, when the old paint is removed, you discover some signs of rot or other damage, you will need to establish the extent of the problem. Small patches of corrosion that caused the timber to become spongy, and soft can be removed carefully before being filled and finished. Other minor issues can also usually be addressed easily.

As well as the state of the timber, you should also look for missing, loose, or damaged putty from earlier repairs, loose or damaged hinges, loose joints, broken sash cords, cracked or broken glass, and draughts and rattles. While these may not be significant enough problems for your windows to require immediate replacement, they will need some attention.

Any problems with your windows are only likely to get worse over time. The sash or casement should be opened and inspected from inside and out to check for any problem areas. Be careful when opening old windows if they are stuck or in particularly bad condition. Overpainting, structural movements and damp weather can all cause windows to jam.

However, if you discover more extensive problems with rot and large parts of the timber turned soft and spongy, then small minor repairs may not be possible nor desirable. When that’s the case, it may be time to consider investing in replacement windows.

Even if your windows have not yet reached that stage, older timber windows will require more maintenance and attention than newly installed windows. However, the careful repair of existing windows and giving them an upgrade to help improve their thermal efficiency will generally be more cost-effective than complete replacements.

Many people in period properties are also keen to preserve the character and history of the house. It’s important to remember that replacement timber windows can be crafted to ensure that they replicate the original windows as much as possible.

Improved energy efficiency

Another reason you may choose to replace rather than repair your timber windows is because of energy efficiency. Warping wood, overpainting that compromises how windows fit, foggy panes and damaged seals can all lead to wood windows becoming less energy efficient over time.

New timber windows can immediately improve your home’s energy efficiency, helping to reduce your energy bills. Some maintenance such as reducing draughts will have an impact, and old windows can be made more thermally efficient.

Updating your windows

Modern wooden double-glazed windows can help bring the style of your home up to date. With a range of beautiful finishes available, you can opt for something contemporary or traditional, helping to give the appearance of your home a new lease of life.

Alternatively, you may be renovating an old property and might want to install new timber sash windows to keep the character of the property intact.
