Timber sash windows are as much about beauty as they are about performance. While the design and craftsmanship play a vital role, the finish you choose can make a significant difference in appearance, durability, and maintenance. Whether you’re restoring existing windows or installing new ones, selecting the right finish ensures your sash windows enhance your home for years to come.
In this guide, we’ll explore the most popular timber finishes, their benefits, and how to choose the best option for your property.
1. Painted Finishes – Classic and Protective
Paint is the most common finish for timber sash windows in the UK. A good quality, microporous paint allows the wood to breathe while protecting it from moisture, UV rays, and pollution.
Advantages:
- Timeless appearance (especially in white or heritage tones),
- Excellent weather protection,
- Easy to touch up when damaged.
When choosing paint, opt for a satin or eggshell finish. Gloss can be too reflective and shows imperfections more easily, while matte can attract dirt.
2. Stained and Varnished Finishes – Showcasing the Grain
If you prefer to highlight the natural beauty of the timber, stains or clear varnishes are ideal. These finishes enhance the wood’s texture and warmth, giving a rich, organic look.
Best suited for:
- Contemporary homes,
- Interiors with exposed timber themes,
- High-end projects where material quality is on display.
Keep in mind that stained finishes require more frequent maintenance and may offer slightly less UV protection than opaque paints.
3. Colour Matching and Bespoke Shades
With today’s technology, you’re not limited to off-the-shelf colours. You can match your windows to your front door, interior décor, or even local conservation colour palettes.
Popular choices include:
- White, cream, or sage green for period homes,
- Anthracite grey or deep blue for a more modern look,
- Two-tone finishes (one colour inside, another outside).
Speak to your sash window supplier – like PM Sash Windows – about available colour options and samples.
4. Conservation and Heritage Considerations
If you live in a listed property or conservation area, there may be restrictions on colour and finish. Always check with your local authority before making changes.
Generally, soft heritage tones and traditional whites are the safest choice for compliance and resale value.
5. Maintenance and Longevity
Regardless of the finish you choose, regular maintenance is key. Painted finishes should be inspected every 3–5 years and touched up as needed. Stained timber may need more frequent re-coating, especially on sun-exposed elevations.
Choosing high-quality, breathable finishes will help reduce peeling and cracking – preserving both the aesthetics and integrity of your sash windows.

Your choice of finish should reflect your home’s character, your personal style, and the demands of the local environment. Whether painted or natural, a well-finished sash window not only looks stunning but lasts for decades.
