Composite decking built correctly, from the ground up.
A deck is only as good as what holds it up. Ellis takes the time on groundwork, levels and subframe that quicker jobs skip, then finishes with Trex boards backed by a warranty of up to 50 years. It's why so much of his work comes from recommendation.

From initial engagement and enquiry to order placement and install, Ellis maintained good communication... The finished decking looks superb, and has a quality look and feel underfoot. Highly recommended.
Don't make the mistake of going with the cheapest option... The installation process was smooth and Ellis couldn't have been more professional or helpful, with great attention to detail ensuring a flawless finish.
We have worked with a number of masters of their craft. Ellis stands out amongst them. 10 out of 10.
Ellis was very professional from start to finish. He came up with very good ideas for the design. Extremely pleased with the finished deck and railing system.
Excellent communication from start to finish. We were away for half of the fitting but Ellis took photos every day...
His attention to detail is to be admired, and he is not afraid of giving you ideas for your project. We cannot rate or recommend Ellis highly enough.

Composite decking FAQs.
Anything else, just ask. Ellis would rather answer a question than have you guess.
How much does a composite deck cost?
It depends on the size, height, ground conditions and which Trex range you choose. Send a photo and rough measurements and Ellis will give you a rough price before arranging a visit.
Do I need planning permission?
Most garden decks don't. As a general rule, a deck raised more than 30cm off the ground usually needs planning permission. Ellis will flag it at the design stage if yours might. Read the full planning guide.
Can you build on a sloped garden?
Yes. Slopes are where a well built subframe matters most. Ellis plans the levels and steps first, and can produce a detailed 3D design render as an optional extra so you can see exactly how it will sit.
Is Trex worth it over timber?
Trex won't rot, splinter or need staining, and it's backed by a 25 to 50 year warranty depending on the range. It costs more up front, and pays that back in years of no maintenance.
Can you replace my old timber deck?
Yes. Timber decking replacement is one of Ellis's core services. The old deck comes up, what's underneath gets checked properly, and it's rebuilt in Trex so it won't rot, splinter or need staining again. More on timber decking replacement.
What does the Trex warranty cover?
Trex boards come with a 25 to 50 year limited residential warranty depending on the range, covering the boards against material defects, fading and staining. Ellis talks you through the exact cover for the range you choose.
Do you do commercial decking?
Yes. As well as garden decks, Ellis installs commercial composite decking for businesses across South Wales. See commercial decking.
Do you cover my area?
Ellis covers Abergavenny, Monmouthshire, Cardiff, Newport, Cwmbran, Pontypool, Brecon, Hereford, Ross-on-Wye and the Cotswolds. Not sure if you're in range? Just ask. See all areas we cover.
