Your Local Composite Decking Supplier

Q: What is composite decking made from?

Composite decking is made from a combination of materials designed to replicate the look and feel of natural timber decking whilst offering superior performance. Our Millboard range uses a fibre-reinforced polyurethane core composed of over a third recycled materials including limestone diverted from landfill, topped with a hand-tinted Lastane surface layer that provides exceptional scratch, fade and slip resistance. Each board is composed of a blend of 38% recycled materials, including limestone diverted from landfill, bonded in a polymer resin. Crucially, Millboard contains no actual wooden fibres, eliminating the risk of warping, rotting, moulding or insect damage.

Q: Does composite decking come with a warranty?

Our Millboard composite decking comes with a 25 year residential warranty and 10 year commercial warranty as standard. It must be activated within 90 days of purchase. To activate it, simply send your receipt directly to Millboard and they will issue your warranty certificate. You can also ask your local branch landscaping team to help you activate your warranty. Other composite decking brands stocked in branch will carry their own warranty terms, so always ask your local EH Smith landscaping team for more details and advice on how to register.

Advice from the EH Smith Landscaping Team

"The main thing that drives people away from composite decking is the price, but it is the best decking option out there. Our composite decking not only looks the part, but it is also hard wearing and long lasting, backed by a extensive warranty up to 25 years. The upfront cost is higher but ultimately you are paying to not do it twice. No wooden fibres mean no moulding, swelling or warping and the lost-head fixings mean there are no screws or nails sticking out like a sore thumb."

Composite Decking FAQ's

What is composite decking made from?

Composite decking is made from a combination of materials designed to replicate the look and feel of natural timber decking whilst offering superior performance. Our Millboard range uses a fibre-reinforced polyurethane core composed of over a third recycled materials including limestone diverted from landfill, topped with a hand-tinted Lastane surface layer that provides exceptional scratch, fade and slip resistance. Each board is composed of a blend of 38% recycled materials, including limestone diverted from landfill, bonded in a polymer resin. Crucially, Millboard contains no actual wooden fibres, eliminating the risk of warping, rotting, moulding or insect damage.

Is composite decking better than wooden decking?

Composite decking offers significant advantages over traditional timber. It requires no sanding, staining or annual treatment, is fully resistant to rot, mould and insect damage, and will not warp or swell over time. Millboard's Lastane surface provides higher slip resistance than timber even in wet conditions, and with a 25 year residential warranty it is built to outlast traditional wood decking considerably. The upfront cost is higher, but as our team put it, you are paying to not do it twice.

Does composite decking come with a warranty?

Our Millboard composite decking comes with a 25 year residential warranty and 10 year commercial warranty as standard. It must be activated within 90 days of purchase. To activate it, simply send your receipt directly to Millboard and they will issue your warranty certificate. It is a straightforward process and well worth doing to protect your investment. You can also ask your local branch landscaping team to help you active your warranty. Other composite decking brands stocked in branch will carry their own warranty terms, so always ask your local EH Smith landscaping team for more details and advice on how to register.

Can composite decking fade, warp, break or crack?

Millboard's fibre-reinforced closed-cellular internal structure is engineered for exceptional strength and durability whilst remaining lightweight. Under normal use and with correct installation it should not crack, split or break. The board composition is entirely wood-free, which also eliminates the risk of the kind of structural degradation that affects traditional timber over time, such as rotting, warping or insect damage. The boards also contain integrated UV stabilisers to ensure impressive fade resistance over time. The elastomeric surface also ensures increased weather resistance against the wide range of seasonal UK weather.

How do I know how much composite decking to buy?

Start by measuring the length and width of your deck area and calculating the square meterage. Factor in any waste from cuts, particularly if your deck has an irregular shape or requires angled cuts, and always order a little more than you think you need. Our landscaping teams across all EH Smith builders merchant branches are happy to help you work out quantities and make sure you order the right amount for your project. It is always better to have a little spare than to run short mid-installation.

Which composite decking colour should I choose?

Think about what is already around your outdoor space. Warmer tones like golden oak composite decking work beautifully alongside traditional brick properties and natural stone, whilst cooler greys like limed oak composite decking and darker finishes such as burnt cedar composite decking suit contemporary rendered properties and modern garden designs. Consider the colour of your house, any existing paving or walling, and how much natural light the space receives. Coming into your local EH Smith branch to see the range in person is always the best approach, our expert landscaping teams can also help you find a combination that ties your whole outdoor space together.

How do I maintain composite decking?

One of the biggest benefits of composite decking is how little maintenance it requires compared to traditional timber decking. There is no sanding, staining or oiling needed. Simply clean as required using appropriate cleaning products for the deck location. Millboard's non-porous Lastane surface actively resists mould and algae growth, meaning your decking should stay looking its best with minimal effort year round.

Posted: November 05, 2026
Categories: News

September marked an exciting step forward for our transport fleet, with the delivery of five new vehicles to support our branches and enhance our delivery capabilities.
As part of our ongoing relationship with Thomas’s Group and West Midlands Hire, we were invited to work with Volvo Trucks. These latest additions represent a continued investment in our fleet, helping us meet the evolving demands of our customers and ensure we can deliver a wide range of building materials safely and efficiently.
New vehicles have been allocated across branches including Olton, Cannock and Leicester. Stourbridge has also welcomed a medium-sized crane vehicle, while Hemel Hempstead has received its new Moffett-equipped vehicle.
A key feature of the new fleet is the installation of Atlas 165 lorry loaders on all crane vehicles. These offer significantly improved lifting capacities compared with the older Hiab cranes they replace, providing greater capability when handling heavier building materials and

The TwinsBuild Brick Throne Comes to EH Smith Shirley
Posted: October 08, 2026
Categories: News

If you have visited our Shirley branch recently, you may have noticed something a little unexpected in the entrance. Not a display of paving slabs or a stack of building materials, but a full size brick throne.
The throne was built over two days by TwinsBuild, the bricklaying duo behind one of the most talked about entries at the SuperTrowel Masters Competition 2026. Twin brothers Jonny and George McFarlane from Derbyshire, aged 22, both passionate about bricklaying and both very much responsible for the impressive structure now sitting at the entrance to EH Smith Shirley.

"We've been laying bricks for seven years now. We really enjoy bricklaying and more than anything we enjoy the detail work which is what inspires us to do builds like this."
~ Jonny McFarlane
We documented the entire build across the two days, from the first brick to the finished throne. Watch the full timelapse and hear from Jonny and George themselves in the video below, and if you want to follow their work, you can
