When planning a timber cladding project, timing can make a real difference to both the installation process and the long-term performance of the timber. While timber cladding can be installed all year round, cooler conditions often create an optimal environment for the boards to settle, reducing the likelihood of movement and helping ensure a lasting finish.
At The Larch Cladding Company, we supply high-quality larch cladding, cedar cladding, and Douglas fir cladding that’s designed to perform beautifully in the UK’s varied climate. In this guide, we’ll explain why cooler days can be advantageous for installation, what you need to consider if fitting cladding during warmer months, and how to get the best results whatever the season.

Why Cooler Days Are Ideal for Installation
Timber is a natural, sustainable material, and like all natural products, it responds to its environment. Because it’s hygroscopic, timber takes in and releases moisture depending on surrounding humidity levels. When boards are installed in cooler, more moderate conditions, ideally between 20°C and 5°C, this process is more gradual and stable.
This makes cooler weather beneficial for several reasons:
- Gentle acclimatisation: The timber adjusts more steadily, reducing the risk of warping or distortion.
- Dimensional stability: Boards fitted at moderate temperatures are less prone to shrinking or swelling in the weeks immediately after installation.
- Longer-lasting finish: By minimising stress on the boards during installation, you help ensure your cladding retains its structure and beauty for years to come.
What About Summer Installation?
It’s important to note that timber cladding can absolutely be installed during summer. Many projects are completed successfully in warm weather, particularly when good practices are followed.
On very hot days, direct sunlight can cause timber to heat unevenly, which may increase movement or surface checking. To avoid this, installers often:
- Work in shaded conditions where possible, or store boards away from direct sun until they’re ready to be fitted.
- Install in the morning or evening when temperatures are cooler.
- Check moisture content before fitting, ideally ensuring it’s below 16%.
With these steps, summer installations can achieve excellent results. The key is awareness of how timber behaves and taking practical measures to manage the conditions.
Choosing the Right Timber Species
Another factor that contributes to success is species selection. The UK’s climate can be unpredictable, so choosing cladding timber that performs well against moisture and UV exposure is essential.
Douglas fir: Known for its strength and resistance to weathering. It performs well in exposed locations.
Cedar: Naturally rot-resistant and stable, making it an excellent option for both residential and commercial projects.
Larch: A robust softwood with natural resins that enhance durability. Over time, it weathers to a beautiful silver-grey patina.
All of these timbers are responsibly sourced and available from The Larch Cladding Company. FSC®-certified timber (FSC-C134890) is available by request and must be confirmed when ordering.
Preparing and Protecting Your Cladding
For the best long-term performance, preparation is just as important as timing.
Moisture content: Always check that boards are sufficiently dried before fitting. This prevents excessive shrinkage once they’re in place.
Coatings and treatments: If you’re planning to oil, stain, or paint your cladding, wait until the timber has had time to stabilise. This initial weathering period allows natural movement and oil leaching (particularly in species like larch and Douglas fir) to settle down.
Application: Coatings should be applied to all faces and edges of each board after cutting. Fire-retardant coatings must be applied according to the manufacturer’s instructions.
Seasonal Advantages of Autumn and Winter
After particularly hot summers, the arrival of cooler, more stable temperatures can create the perfect opportunity for cladding installation. Not only does this reduce the risk of heat-related timber movement, but it also gives your cladding time to acclimatise ahead of harsher winter conditions.
That said, timber cladding can be installed year-round, provided you work with trusted suppliers and follow professional guidance on storage, acclimatisation, and installation techniques.
Why Work with The Larch Cladding Company?
At The Larch Cladding Company, we understand how important it is to get both the product and the timing right. We supply a wide range of exterior timber cladding, including vertical timber cladding profiles such as shiplap, tongue and groove, feather edge, square edge, and rainscreen.
Our products are:
- We responsibly source our materials from sustainable forests and, as an FSC®-certified supplier (FSC-C134890), can provide FSC®-certified timber on request.
- Cut to order, with bespoke profiling available for unique projects.
- Delivered nationwide, ensuring reliability wherever you’re based.
Whether you’re installing cladding on a garden studio, a new-build development, or a large commercial scheme, we provide the expertise, advice, and timber to help your project succeed.
Ready to Start Your Cladding Project?
Cooler conditions provide the most stable environment for fitting timber cladding, helping boards settle gently and maintain their integrity over time. However, with careful planning and proper installation techniques, cladding can be fitted successfully in any season, summer included.
If you’re planning a project and need advice on the best timber species, profiles, or finishes, our team is here to help. From sustainable sourcing to expert recommendations, we’ll ensure you have the knowledge and materials to create a stunning, long-lasting result.
