Wood decking versus composite

Composite Decking vs Traditional Timber: Which Is Right for Your Devon or Cornwall Garden?

By Kevin Hampton, Colt Carpentry Devon

A well-designed deck gives you somewhere to sit with a morning coffee, enjoy a meal outside or make better use of an awkward garden. But before choosing colours and planning the furniture, there is one important decision: composite decking or traditional timber decking?

My starting point is how you want to use the space, the look you enjoy and the amount of maintenance you are happy to take on. Both materials can create an attractive outdoor area. The right choice depends on your garden and your priorities.

At Colt Carpentry Devon, I believe a good decking project starts with an honest conversation. If you are planning garden decking in Devon or Cornwall, here is what to consider before making your decision.

Start with your garden, not just a sample board

A board that looks good in a showroom is only part of the picture. Think about where your decking will sit. Is it a sunny terrace, a shaded corner beneath trees or an exposed space near the coast? Will it connect to your kitchen, provide seating beside a garden room or help you use sloping ground?

I would also consider the route through the garden, the position of steps and whether handrails are needed. These details influence how useful the finished space feels every day.

Before comparing materials, decide what matters most: natural character, less routine upkeep, the initial budget or a particular colour and finish.

What is composite decking?

Many composite decking boards combine wood fibres with plastic. Capped products have an additional outer layer designed to help protect the surface. Other alternatives use different materials, including wood-free mineral and resin systems.

This means “composite” covers a range of products. Their performance, fixing requirements and warranties are not interchangeable.

Composite can suit homeowners who want a coordinated finish without regularly refinishing the boards. It is available in different colours and textures, making it an option for both contemporary gardens and more traditional outdoor spaces.

However, compare the actual product before buying. Look at its care instructions, installation guide and warranty terms, alongside the sample.

Why choose traditional timber decking?

Real wood brings individual grain, colour variation and a natural feel to a garden. It can sit comfortably alongside timber fencing, planted borders and bespoke garden joinery.

Pressure-treated softwood is often a practical starting point when the budget is important. Suitable hardwoods and modified timbers offer other choices, although their cost and performance vary by species and specification.

Timber can also offer flexibility when you want to alter the finish later, using a compatible coating. If you prefer a naturally weathered appearance, ask which timber and care routine suit that aim.

Choose wood specified for its intended outdoor use. The word “hardwood” alone does not tell you how durable a particular board will be.

Which costs more to install?

For many projects, treated softwood decking has a lower starting cost than composite. That does not mean every timber deck is cheaper: premium hardwood and detailed carpentry can change the comparison considerably.

The useful figure is the price for the complete project. Boards are only one part of that cost. Ground preparation, foundations, posts, joists, fixings, edging, steps and handrails all need to be included. Access and the removal of existing decking can also affect the work involved.

When comparing decking quotes, ask whether both include the same area, supporting structure and finishing details. A low board price does not necessarily produce the lowest completed cost.

Composite may reduce spending on refinishing over time, but savings depend on the products and care involved. I would compare the full installation and likely upkeep before deciding which offers better value for your home.

How much maintenance will each need?

Composite decking is usually chosen partly for its lower maintenance requirements. Many modern products do not need routine staining, painting or sealing. They still need cleaning: leaves, mud and food spills should not be left to accumulate. Follow the manufacturer’s instructions for cleaners and pressure washing.

Timber decking also needs regular cleaning and inspection. Where an oil, stain or water-repellent finish is used, it will need refreshing as appropriate to the product and conditions. There is no single treatment schedule that suits every wooden deck.

With either material, keeping drainage gaps clear and checking for loose fixings or damage is a sensible part of looking after the finished installation.

What about wet weather and summer heat?

For gardens across Devon and Cornwall, wet-weather performance deserves careful attention. No decking should be assumed to be completely slip-proof. Dirt, algae and fallen leaves can affect grip, so cleaning matters whatever the board material.

For shaded areas, steps or frequently used routes, ask about the specific board’s tested slip resistance and suitable surface options. Grooves or an embossed texture alone are not proof of good grip.

Sun exposure matters too. Composite boards can become hot in direct sunshine, particularly darker finishes. Timber and other outdoor surfaces can also heat up. Consider colour, shade and how children or pets will use the space when making your choice.

How long will the decking last?

I would be cautious about any comparison that gives every timber deck one lifespan and every composite deck another. Material quality, the site, installation and care all make a difference.

A product warranty is useful, but it is not a promise that every part of the deck will last for the same period. Check what it covers, what is excluded and which installation conditions apply.

The supporting frame deserves particular attention. New boards cannot correct decayed joists or inadequate supports. If you are replacing old garden decking, the condition of the structure underneath needs assessing before deciding what can be retained.

Why the installation matters as much as the boards

The finish you see relies on the work beneath it. Support spacing, drainage, ventilation and appropriate fixings all contribute to a successful deck.

Composite boards must be fitted to the selected manufacturer’s instructions, including the required gaps for movement. Do not assume that joist spacing suitable for an old timber deck will suit new composite boards.

My approach is to think about the complete space: how the boards meet the edges, how the steps connect to the garden and how the handrails fit the design. Careful carpentry brings those details together.

Which is the more sustainable choice?

Neither material automatically wins on sustainability. For timber, look for responsibly sourced products, including appropriate FSC or PEFC certification. For composite, check the manufacturer’s evidence on recycled content and what happens to the boards at the end of their life.

Also consider durability, repair options and whether sound existing components can be retained. Choosing suitable materials and building the deck properly helps avoid unnecessary replacement.

My advice: choose the deck that suits your priorities

If natural grain and the feel of real wood are important to you, timber is well worth considering. If you prefer a consistent finish with less routine refinishing, a suitable composite product may be the better fit.

I would encourage you to look at samples outdoors, compare complete quotes and be realistic about the care you are happy to provide. A thoughtfully planned timber deck can be an excellent choice, just as a well-specified composite deck can be.

Frequently asked questions

Is composite decking maintenance-free?

No. It generally needs less refinishing than timber, but regular cleaning and the manufacturer’s care guidance still matter.

Can composite boards be fitted onto an existing timber frame?

Sometimes, but only after checking the frame’s condition, strength, support spacing and compatibility with the chosen decking system. Reusing it should never be assumed from the condition of the surface alone.

Is timber decking suitable for a Devon or Cornwall garden?

Yes, when the timber is properly specified, installed and cared for. The garden’s exposure, shade and drainage should inform the design.

What information helps with a decking quote?

Approximate dimensions, photographs, your location and an idea of the finish you want are a helpful starting point. Mention existing decking, slopes, restricted access, steps and handrails so the discussion covers the whole project.
