Why we recommend it — and when it’s the right choice

When it comes to premium decking, Millboard is our go-to choice for many projects. It combines the natural appearance of timber with the durability and low maintenance of modern composite materials — without many of the drawbacks found in standard composites.

For homeowners in Chichester and the surrounding areas, Millboard decking is particularly well suited to damp, shaded, or high-use gardens where longevity and appearance really matter.

This page explains what Millboard decking is, why we rate it so highly, and whether it’s the right option for your garden.

What Is Millboard Decking?

Millboard decking is a wood-free composite decking product made using a unique resin mineral core and finished with a realistic hand-moulded surface taken from real oak boards.

Unlike many composites:

It contains no timber fibres
It does not absorb water
It does not rot, swell, or warp

Each board is individually moulded, giving it a far more natural appearance than standard grooved composite decking.

Why We Recommend Millboard Decking

Millboard isn’t the cheapest decking — and that’s exactly why it performs so well long term.

✅ Exceptional Resistance to Moisture

Millboard has an extremely low water absorption rate, making it ideal for:

Shaded gardens
Damp ground conditions
Areas prone to algae and moss

This is a big advantage in many West Sussex gardens.

✅ Natural Timber Appearance (Without the Downsides)

Millboard is often chosen by homeowners who:

Love the look of timber
Don’t want the maintenance
Want consistent colour and finish

There are no repeating patterns, and the textured grain feels far more authentic than most composite boards.

✅ Very Low Maintenance

Millboard requires:

No sanding
No staining
No painting

Routine cleaning is usually all that’s needed to keep it looking good.

✅ Excellent Durability & Safety

Millboard boards are:

Highly slip-resistant
Resistant to cracking and splitting
Comfortable underfoot
Suitable for family gardens

They’re also fixed with a hidden fixing system, giving a clean, high-end finish.

Is Millboard Right for Every Garden?

Not always — and that honesty matters.

Millboard may not be ideal if:

Budget is the main driver
A very minimalist or industrial look is preferred
The deck is temporary or short-term

In those cases, other composite or timber options may be more suitable.

Installation Matters With Millboard

Millboard is a premium product — and it needs to be installed properly to perform as intended.

Correct installation includes:

A solid, well-ventilated subframe
Correct joist spacing
Suitable fixings
Allowance for movement
Good drainage beneath the deck

Poor structure undermines even the best decking boards.

How Long Does Millboard Decking Last?

When installed correctly, Millboard decking can last 25–30 years or more with minimal maintenance.

Its longevity comes from:

No timber to rot
Minimal moisture absorption
Strong, stable core
High-quality surface finish

For homeowners wanting a long-term solution, it’s a very strong option.
