PREPARING YOUR TIMBER FOR THE GARDEN SEASON

A GUIDE TO SUMMER-READY DECKING AND FENCING

As gardens across the UK come back into focus for homeowners, developers, and contractors alike, the demand for fencing and decking installations continues to hold strong. Timber remains the preferred material for many, appreciated not only for its visual appeal but also for its adaptability and relative ease of installation. But with increased exposure and use during the summer months, the value of ongoing timber maintenance can’t be overstated. The performance and longevity of timber structures – particularly decking and fencing – depend just as much on what happens after installation as they do on the quality of the timber itself. As the summer season gets underway, it’s the right time to remind clients and colleagues that timber treatment isn’t a one-off task. If fencing and decking are to live up to expectations, both in form and function, preparation and upkeep are non-negotiable.

Decking oils and fence treatments: first line of defence

This time of year, many projects focus on rejuvenation—and one of the simplest ways to extend the life of timber structures while enhancing their surface integrity is by applying decking oil. Koppers Protim ® Wood Oils and Protim ® End Coat are excellent choices for this purpose. These oils penetrate the grain, provide protection from UV exposure, and help maintain the timber’s flexibility – critical in preventing cracking and warping during hot, dry spells. Similarly, re-treating fencing is essential, especially after prolonged wet or frosty periods. Protective stains and preservatives don’t just enhance appearance -they serve as vital barriers against rot, fungi, and moisture ingress. This is especially important as clients begin to expect more from their outdoor spaces – fencing and decking are now often part of more elaborate, multi-use garden environments that are expected to stay looking sharp throughout the year. Increasingly, darker, richer finishes are being used to create high-end aesthetics. The move toward bolder colours, such as charcoal and deep walnut, reflects a shift in consumer preference, but also presents a challenge: these finishes tend to highlight wear more obviously. This makes consistent maintenance even more crucial -not just for appearance, but for preserving the structure underneath. Treating the vulnerable points Beyond surface-level treatments, it’s worth focusing attention on areas that are frequently missed but often cause longer-term issues such as: cut ends, drill holes, and surface nicks. These untreated zones can act as entry points for moisture and are often where early signs of decay begin. End coat sealers offer an effective solution, helping to prevent rot and fungal damage by sealing exposed fibres. For contractors and installers, it’s good practice to factor this into the installation process itself. Ensuring that all modified or cut components are immediately treated on-site with appropriate end-grain preservatives can significantly reduce call-backs and premature deterioration.

Maintenance schedules: a practical necessity

For both trade professionals and end-users, the idea that treated timber is “fit and forget” still persists. But even factory-treated timber needs additional care over time. Annual maintenance, typically before or during the early summer season, is not just advisable-it’s essential. The exact schedule will vary depending on timber species, finish type, exposure levels, and regional climate. However, a general recommendation is to re-treat fencing and decking at least once a year. Doing so before peak summer use ensures that protective products can cure under favourable conditions and provide maximum resilience when it’s needed most.

Adding value through ongoing care

For those in the fencing and landscaping supply chain, there’s an opportunity here to educate customers and end-users-not just on the importance of treatment, but also on how to apply it correctly and when. Maintenance might not always be the most visible part of a timber installation, but it’s the element that determines how long that installation will perform.

With the right treatment schedule, good preparation, and smart product use, timber remains one of the most rewarding materials to work with. Its natural character, combined with new finishes and more advanced treatment formulations, means it can meet the demands of today’s outdoor environments-provided it’s properly looked after.

As the garden season ramps up, now is the time to prepare timber installations for the months ahead and to set expectations for care that extends far beyond summer.
