2 Composite Decking Pros in Belfast Who Saved Us from Splinters
I used to put off fixing our garden for ages, even though it was clearly past its prime. Actually, our outdoor space got so bad that guests started calling it ‘vintage’—I wasn’t really sure if that was meant as a compliment or not.
But when our dog straight-up refused to step outside unless it was bone dry and puddle-free, I got the real wake-up call. After one too many sunburns and a nasty splinter trying to fix it myself, I figured it was time to ask for help.
So I hit up my most DIY-obsessed pals and asked for contractor recommendations. If you’re searching for the best decking pros in Belfast who can save you a lot of time and money, we’ve got you covered below.

FDSNI Fencing Decking Specialists is one of our top composite decking installers in Belfast for both private and commercial clients.
It offers bespoke designs for garden layouts, so we bet you can plan your dream garden with its team. You can also add fences, gates, bench seats, and gazebos to make your space more unique.
Not only that, but we also like the environmentally friendly decking boards the company uses for a guilt-free project.
Moreover, it’s handy for us that the boards used are weather-resistant and splinter-free—safe for children and pets! Plus, there are tons of colours and finishes to choose from.
We’re also stoked about the complimentary consultations and design, as well as the detailed quotations the staff provides for full transparency.
Just note that the premium services here can be more expensive than several other budget installers.

2. HMC Joinery & Building

Address: 29 Rosetta Avenue
Phone: 02890 201599, [email protected]
If you need woodworking experts, HMC Joinery & Building offers quality craftsmanship known for its function and form.
Besides professional composite decking installations, the team provides timber alternatives and bespoke services for your garden. This includes seating, steps, and cladding (structure covering or coating).
And if you’re planning something bigger, we’re in awe that the company can do full outdoor renovations involving patios and landscaping. Ideal for really big spaces, we say.
Another thing we’re impressed by is the team’s ability to keep the worksites tidy. Personally, we think this is an underrated yet very important consideration for picky clients.
Nevertheless, one client we talked to mentioned that his project timeline got extended unexpectedly. If your project needs complex customisations, we advise communicating these from the get-go to help manage expectations.
