Factors affecting Trex decking prices

Whilst Trex decking is more expensive than some other brands. The boards only contribute a small amount to the overall cost of renovating your garden.

Many factors play a role in the Trex deck cost, including:

Garden design

If Trex decking is part of a wider garden transformation, there may be costs associated with designing your garden and buying and installing hard and soft landscaping materials.

Labour

Depending on the project’s scope, if any groundwork is required or if you want any raised structures, the labour cost can be the largest or smallest part of the project cost.

If you install the Trex deck yourself or hire a deck builder when their demand is lower (typically in the winter months), this can help bring the cost down.

Trex board type

Trex comes in different versions, colours and styles designed to suit a range of budgets, including Trex Select, Enhance and Transcend.

Limited edition colours tend to cost more. For those on a budget, we recommend the Trex Select range.

Add-ons

A Trex deck is more than just the flooring. You can also opt to add in railings, stairs, roofing, lights, benches and other features.

A railing may be required to meet Building Regulations, depending on the height of the decking.

If you plan on using an existing substructure, you’ll need to factor in the cost of removing any existing decking and making good of the substructure.

We recommend you ask your Trex installer to survey this to ensure it can be used

All of those so-called add-ons will increase the total Trex decking cost.

Size of your decking area

The larger the area or the more unusual the shape, the greater the cost. Curved designs cost more to build than simpler, straight sections.

You can expect to pay around £100+ per square metre for the boards with any add-ons priced separately.

Is Trex decking worth the cost?

With high durability and an expected life of over 25 years, Trex pays for itself over time. Here’s how it compares to other types of decking:

Timber – Unlike traditional timber decking, Trex composite boards don’t rot or go mouldy. Whilst wooden boards can often vary in quality, Trex boards are always consistently high quality, helping to reduce waste and speed up the installation process.

Stone – Stone flooring can be prone to cracking, erosion and damage over time. It’s also slippery when wet. Trex decking does away with all of these problems.

PVC – Whilst PVC is low maintenance. It’s less environmentally friendly and prone to fading and staining over time. Trek is equally low maintenance, without the other drawbacks.

Other composite decking products do exist, including Dura and TimberTech.
