Choosing Between Timber and Composite Decking

Neither timber nor composite decking is better for everyone. Timber costs less upfront and has a natural look, but it needs regular upkeep. Composite costs more at the start, but it needs far less maintenance and usually lasts longer. The right choice depends on your budget, how much time you want to spend looking after the deck, and the conditions in your garden.

This guide sets out the pros and cons of each material, compares them on the factors that matter most, and finishes with a simple decision guide. It is written for UK homeowners generally, with a short note on Scottish conditions. Fife Premier Handyman Services works on decking and carpentry projects across Fife, and these are the questions we hear most often from people planning a deck.

The Short Answer

• Timber suits people who want a lower upfront cost, a natural look and who do not mind regular maintenance
• Composite suits people who want low upkeep, a consistent finish and a long lifespan, and who are happy to pay more at the start
• Cost over time can be closer than it looks, because timber needs ongoing treatment and may be replaced sooner
• Both can be slippery when wet, so choose a grooved or textured board whichever you pick
• Installation quality matters as much as the material, especially the frame, ventilation and drainage
• There is no overall winner. The best deck is the one that fits your garden, budget and lifestyle

Timber vs Composite at a Glance

Timber Decking: The Basics

Timber decking comes in two main groups. Softwood, usually pressure treated pine or spruce, is the cheapest and most common. Hardwood, such as balau, ipe or cumaru, is denser, tougher and more expensive.

Pros of Timber

• Lower upfront cost. Softwood is the most affordable decking material, which makes a deck achievable on a tight budget
• Natural look and feel. Real wood has grain, warmth and variation that many people prefer
• Easy to work with. Timber is simple to cut, shape and fix, which helps with custom designs and awkward spaces
• Easy to refinish. Faded or worn boards can be sanded, cleaned and re-oiled or stained
• Simple repairs. Individual boards can be replaced without much fuss, and new boards weather to blend in
• Widely available. There is a huge choice of styles, grades and finishes
• Can be sourced responsibly. Certified timber comes from managed forests and is a renewable material

Cons of Timber

• Needs regular maintenance. Softwood in particular usually needs cleaning and treating every year or two to protect against moisture, rot and fading
• Can warp, split and splinter. As timber dries and weathers, boards can twist, crack or raise splinters
• Shorter lifespan for softwood. Treated softwood commonly lasts around 10 to 15 years with good care
• Prone to algae and moss. Damp, shaded timber grows green film quickly, and this can be slippery
• Colour changes. Timber fades and silvers over time unless it is treated regularly
• Hardwood costs more and is harder to fit. It is tough and long lasting, but it needs pre-drilling and takes more effort to install
• Responsible sourcing matters. Cheaper or unverified timber can come from poorly managed sources

Composite Decking: The Basics

Composite decking is made from a blend of wood fibres and plastic. Better products have a protective outer cap or shell that guards the core against moisture, staining and fading. Cheaper uncapped boards are less resistant, so the quality of the board matters.

Pros of Composite

• Very low maintenance. There is no need for staining or oiling. Regular sweeping and washing is usually enough
• Resistant to rot and insects. Composite does not decay like timber
• Long lifespan. Good quality boards often last 25 years or more, and many come with long warranties
• Consistent finish. Boards keep a uniform colour and appearance, with a wide range of tones
• Few splinters. The surface is smoother and kinder to bare feet
• Good in damp, shaded spots. It copes with moisture better than most timber, though it still needs cleaning
• Wide choice of textures. Many boards have grooves or embossed grain that improve grip and appearance

Cons of Composite

• Higher upfront cost. It costs more than softwood, and some premium boards cost more than hardwood
• Can get hot in strong sun. Dark boards in full sun can feel very warm underfoot
• Can scratch or mark. Sharp objects and heavy furniture can scar the surface, and scratches cannot be sanded out like timber
• Fades over time. Most boards soften in colour during the first months, then change slowly
• Can grow mould and algae. Dirt and damp still allow surface growth, so cleaning is still needed
• Quality varies. Cheap uncapped boards can stain, fade or absorb water more easily
• Less natural feel. Some people find it looks or feels less authentic than real timber
• Warranties have conditions. Poor installation or neglect can limit your cover

Cost Compared

Prices vary with the product, the size of the deck and the supplier, so these are rough, indicative figures to help you compare.

These are general UK guides and not quotes. A real price depends on your site, your chosen boards and your installer.

The Cost Over Time

The cheapest deck to build is not always the cheapest to own. Softwood needs regular products and labour, and it may need replacing sooner. Composite has a higher starting price, but it needs little upkeep and often lasts longer. If you plan to stay in your home for many years, the gap in cost over the long run can narrow or even reverse. If you plan to move soon, a cheaper deck may be the more sensible choice.

Maintenance Compared

Maintenance is often the deciding factor.

Timber

• Clean once or twice a year to remove dirt, moss and algae
• Treat with a stain or oil every year or two, depending on the product and exposure
• Check fixings and boards for loose or damaged areas
• Re-treat cut ends after any repairs
• Sand and refinish worn patches as needed

Composite

• Sweep regularly to clear leaves and dirt
• Wash with warm water and a mild cleaner a few times a year
• Clear the gaps between boards so water can drain
• Follow the manufacturer’s cleaning advice, particularly if you want to keep the warranty

Composite is not completely maintenance free, but it asks for far less time and effort than timber.

Looks and Feel

Looks are a matter of taste, and both materials have a lot to offer.

• Timber has natural variation, warm tones and a real wood feel. It ages in a way many people find attractive, especially hardwood
• Composite offers consistent colour and a tidy finish, with many modern boards that imitate timber grain convincingly
• Edges and details differ. Timber can be shaped and customised more easily, while composite relies on the profiles and trims the manufacturer supplies
• Colour choice is wide in both, though timber’s colour changes more as it ages

Always view a large sample in your own garden, because colour looks different in natural light.

Grip, Safety and Comfort

Safety matters more than people expect on a deck.

• Both materials can be slippery when wet, especially when moss or algae builds up
• Choose grooved or textured boards, whatever you pick
• Keep the surface clean, because algae causes most slips
• Splinters are more common with timber as it ages, which matters for bare feet and pets
• Heat can be an issue with composite in strong sun, particularly darker colours, while timber is usually more comfortable on very hot days
• Steps and edges deserve extra care, with grip strips if needed

Lifespan and Durability

Lifespan depends heavily on the quality of the product, the installation and the care it receives.

• Softwood commonly lasts around 10 to 15 years with good care
• Hardwood often lasts 20 years or more
• Composite often lasts 25 years or more for quality boards, with warranties that reflect this

In every case, the frame underneath matters. A deck with a poorly protected frame can fail early, whatever the boards are made from, so airflow, drainage and durable framing are essential.

Repairs and Changes

Timber is simple to repair and adjust. Damaged boards can be replaced, rough areas can be sanded, and the whole deck can be refreshed with a new stain or oil. Composite cannot be sanded or restained in the same way, so a damaged board is normally replaced. It is worth keeping a few spare composite boards, because matching a product years later can be difficult.

The Environmental Picture

The environmental case is mixed, and it depends on the product.

• Timber is renewable when it comes from responsibly managed forests, so look for recognised certification. Treatments and long distance transport affect its footprint
• Composite often uses recycled wood fibres and plastics, which keeps waste out of landfill, but it contains plastic, and recycling at the end of its life varies
• Longevity matters. A deck that lasts many years uses fewer resources over time than one replaced early

If this matters to you, ask suppliers about sourcing, recycled content and end of life options.

A Short Note on Scottish Conditions

Scottish gardens often have damp, frost and shade, which affect both materials. Timber needs more frequent cleaning and treating to cope with persistent moisture, and a dry window for treatment can be hard to find. Composite handles constant dampness better, but it still needs cleaning to prevent mould and algae. Whichever you choose, prioritise grooved boards, good airflow beneath the deck and sensible drainage. Our article on the best decking material for Scottish weather goes into more detail.

Decision Guide

Use this to weigh the choice for your own situation.

Choose timber if:

• Your budget is tight and you want the lowest upfront cost
• You love the natural look and feel of real wood
• You are happy to clean and treat the deck regularly
• You want the flexibility to sand, refinish and change the look later
• The deck sits in a sunny, open spot with good drainage

Choose composite if:

• You want the lowest possible maintenance
• You plan to stay for many years and value long term value
• The deck is in a shaded, damp or sheltered position
• You want a consistent finish with few splinters
• You are happy to pay more at the start

Consider hardwood if:

• You want real timber but with a longer life than softwood
• You can afford a higher upfront cost and an occasional oiling

Frequently Asked Questions

Is composite decking better than timber?

Not necessarily. Composite needs less maintenance and often lasts longer, while timber costs less upfront and has a natural look. The better choice depends on your budget, how much upkeep you want to do and the conditions in your garden.

Is composite decking cheaper than timber in the long run?

It can be, particularly compared with softwood. Composite costs more at the start, but it needs little upkeep and often lasts longer, whereas timber needs regular treatment and may be replaced sooner. How it works out depends on how long you keep the deck.

Does composite decking need any maintenance?

Yes, but far less than timber. You should sweep it regularly, wash it with a mild cleaner and keep the gaps clear. It does not need staining or oiling.

Does timber decking last as long as composite?

Not usually. Treated softwood commonly lasts around 10 to 15 years with good care, hardwood often lasts 20 years or more, and quality composite often lasts 25 years or more.

Is composite decking slippery?

It can be when wet, particularly if algae or moss builds up. Choose a textured or grooved board, keep the surface clean and check any slip rating the manufacturer provides.

Does composite decking get hot?

It can in strong sun, particularly darker boards. Timber is generally more comfortable on very hot days, though it can also get warm. Lighter colours and shade can help.

Can I repair composite decking?

Individual boards can usually be replaced, but composite cannot be sanded or refinished in the same way as timber. It helps to keep a few spare boards in case a matching product becomes hard to find.

Which is better for a shaded garden, timber or composite?

Composite generally copes better with damp, shaded conditions, because it does not rot like timber. Both still need regular cleaning to prevent algae and mould.

Final Thoughts

Timber and composite each have real strengths. Timber offers a lower upfront cost, a natural look and easy repairs, while composite offers low maintenance, long life and a consistent finish. The right choice comes down to your budget, how much time you want to spend on upkeep and the conditions in your garden. Choose grooved boards for grip, build the frame and airflow properly, read the warranty and look at samples before you decide. Do that, and either material can give you a deck you will enjoy for many years.
