Why DIY Installers Choose Cladco Composite Decking

According to a 2025 YouGov poll, 54% of Britons consider themselves to be dab hands when it comes to DIY. From flat-pack furniture to putting up a new garden fence after a recent storm, many of us love nothing more than reaching for our trusty tool belt, getting creative and bringing our ideas to life.

Not only can it be incredibly rewarding to sit back and admire something you’ve built yourself, but it’s also a great way to keep costs down. While hiring trade professionals can take some of the stress out of a home or garden renovation, it can also seriously eat into your budget — sometimes resulting in compromises on materials or design.

So, if you’re on the lookout for your next DIY project — something you can really get your teeth into — it’s no surprise if your garden has recently become a prime target.

Each year, more and more homeowners in the UK explore ways to turn their outdoor space into a practical extension of the home, and for many, decking is a natural choice, which, if you ask us, is a very good one.

But while putting up a bookshelf or assembling a shed might feel manageable, installing a full garden decking system can feel like a much bigger step. It’s at this point that many people pause and ask themselves:

• “Can I actually install this myself?”
• “Which decking material is the best?”
• “What tools will I need?”
• “What fixings should I be using?”

If that sounds familiar, don’t worry, you’re not alone. And it’s exactly why many DIY installers begin looking for decking options that feel more straightforward to work with, without compromising on the finished result. That’s where Cladco composite decking often comes in.

It offers a practical solution for customers who want to take on their own project with confidence. In this article, we’ll take a look at many of the reasons why DIY enthusiasts continue to choose Cladco’s Signature and ProDeck composite decking for their projects.

It’s a fair question — and one many DIY installers ask before getting started.

The short answer is: in many cases, yes, especially if you’re comfortable taking on practical projects and following the right preparation and installation steps.

Many Cladco customers have already taken on their own decking projects, creating some truly inspirational outdoor spaces — many of which can be seen in our decking gallery and case studies.

Installing composite decking isn’t a small job, but for those with some DIY experience, it can be a manageable and rewarding project, particularly for straightforward garden layouts.

It’s worth bearing in mind how elaborate your decking design is, as this can impact how straightforward the installation will be. A rectangular deck on a flat surface will be far more manageable for a confident DIYer than something that features multiple levels, steps, balustrades and other features.

And while no DIYer ever likes being told what to do, we always stress the importance of following installation instructions. Not only does this help support a successful build, but it also helps protect your product’s warranty.

Before getting started, it’s worth understanding what a typical composite decking installation involves. Most projects follow a clear set of stages, beginning with preparing your space, researching product options, building a sturdy subframe, and then fixing your decking boards into place using the right clips and fixings.

Taking the time to prepare these elements properly can make the process far more straightforward and help avoid issues later down the line.

To make the planning stage a bit easier for our customers, we created a handy online decking calculator on our site, which helps take the guesswork out of organising your project. Rather than relying on what ‘looks right’ or a gut feeling, you can map out your space, choose your materials, and work out the quantities of boards, trims, screws and clips you’ll need.

For many DIY installers, another reassuring point about Cladco composite decking is that it can usually be cut using standard woodworking tools. If you’ve already taken on projects like fencing or furniture assembly, there’s a good chance you’ll already have a lot of what you need, meaning there’s often no need to worry about buying or renting specialist equipment.

When it comes to fitting your boards, one feature many customers find particularly helpful is the Cladco T-clip system, with both Signature and ProDeck T-clips available depending on your build. Installed between each board, these clips help to maintain consistent spacing and create a neat, hidden finish without visible screws on the surface.

To support DIY installers throughout the process, both our Signature and ProDeck composite decking ranges are backed by comprehensive installation guides, alongside plenty of practical advice in our Help & Advice section. These cover everything from recommended expansion gaps and drainage tips, to ensuring adequate airflow — all things that can be easy to overlook if you’re new to decking.

If you’re starting from scratch, our DIY guide on how to build decking is a great place to begin. And if you want to avoid a few common headaches, it’s well worth checking out our guide to common decking installation pitfalls too.

The truth is, there are several practical reasons why DIY installers are choosing Cladco composite decking over traditional timber.

One of the key reasons is the range of trims, fixings and clips available, all designed to work together as part of a complete decking system. 
While a bag of nails or screws and plain timber boards may be the perfect blank canvas for an experienced carpenter, our composite decking boards are designed to help make installation more straightforward for those taking on the job themselves.

As already covered, we also have a wealth of advice and support for our customers, helping to explain everything from preparation and installation through to aftercare. If you can’t find the answers you’re looking for (and how could you?), our friendly, experienced team are on hand to support you, whether via phone, email or our live chat.

There’s also the consistency of the boards themselves to consider. Unlike natural timber, which can vary in shape, condition and colour, composite decking boards are manufactured to be more uniform. For DIY installers, this can help make the fitting process feel more predictable, with fewer unexpected differences between boards to work around.

It’s worth noting that all composite boards are manufactured with a tolerance of up to 5mm in length and width due to the natural materials used and the manufacturing process. This is a standard industry allowance and isn’t expected to affect performance once installed.

So, there we have it. Taking on your own composite decking project might not be as big a leap as you first thought.

It can feel like a big step at first, but as you’ve hopefully seen over the course of this blog, with the right preparation and materials, it’s one that many Cladco customers and DIY enthusiasts successfully tackle every year.

With a system designed for simplicity and practicality, straightforward fixing solutions and plenty of guidance along the way, Cladco composite decking offers a practical option if you’re looking to transform your outdoor space themselves, without making the whole process feel harder than it needs to be.

It’s this combination of ease, support and consistency that continues to make it a popular choice for DIY installers.

Whether you’re still planning your layout or ready to get started, exploring your options early on can help you approach the project with confidence. Trying out our decking calculator is a great place to start, helping you plan your space and work out exactly what you’ll need. You can also order samples to get a better feel for different colours and finishes, and if you’re ever unsure, our team is on hand to point you in the right direction.
