What we do, and how we do it

Composite decking is the right choice when you want the look of timber without the maintenance. The boards are capped, so they do not absorb water, they do not splinter and the colour stays where it started. The frame underneath is what decides whether the deck feels solid in year five, so we build it on treated or aluminium joists at the right centres, with the correct fixings and a slight fall so it drains.

We install it as standalone decks, as level changes between a patio and a lawn, and as wraparound terraces for bifolds. The fascia and edge details are the part you notice every day, so we take the time to get them clean and consistent.

Your options

Choosing what goes down

  • Capped composite boards

    Fully capped boards with a protective shell on all sides. Resistant to stains, moisture and fading, and they clean with a brush and water.

    Best for: Family gardens, dining areas and anywhere you want a low maintenance surface.

  • Aluminium sub-frame

    A metal joist system that will not rot, warp or split. More expensive than timber but it lasts the life of the boards and keeps the deck perfectly level.

    Best for: Decks over damp ground, shaded gardens and customers who want the longest lifespan.

  • Treated timber sub-frame

    Pressure-treated timber joists with the correct spacing and fixings. Proven, cost-effective and easy to inspect in the future.

    Best for: Most residential decks where budget matters as much as lifespan.

  • Fascia and edge trims

    Matching boards used to box in the frame and finish the exposed edges, so the deck looks built rather than bolted together.

    Best for: Every deck. The edge is what you see from the lawn and from the house.

Design - Build - Bloom

Design - Build - Bloom, applied to composite decking

  1. Design

    We measure the space, work out the board direction so the joins fall naturally, and agree the shape, steps and fascia details. You see the layout before the frame is ordered.

  2. Build

    Old surface out, frame in at the correct centres with a slight fall, boards fixed with colour-matched fasteners, and fascia boards fitted to hide the frame. Our own carpenters, and the site is swept every evening.

  3. Bloom

    Borders reinstated to the deck edge, planting positioned to soften the fascia, and a quick guide on how to clean it. The deck should look like part of the garden, not a platform dropped on top of it.

Price guide

Most projects land between £4,000 and £12,000

Size, height, frame choice and access set the price. A small ground-level deck in a sheltered garden sits at the bottom; a large raised deck with steps, balustrade and an aluminium frame sits at the top.

We publish this so you can decide whether we are the right fit before anyone gives up an evening. We are not the cheapest quote you will get. Every price is fixed in writing after a site visit, no day rates and no surprises mid-build.

FAQs

Composite decking questions we get asked

How long does composite decking take to install?

A straightforward ground-level deck is usually three to five days. Add a couple of days if it is raised, has steps or a balustrade, or if the old deck has to be removed first.

Does composite decking need planning permission?

Usually no. Decking under 300mm above ground level and covering less than half the garden normally falls under permitted development. Raised decks that overlook a neighbour, or decks in front gardens, can need consent. We check at the site visit.

Is composite decking slippery?

Good quality capped composite has a slip-resistant grain and is generally less slippery than timber when wet. The main safety issue is usually the frame, not the surface, which is why we build it level and secure.

Can you build it over an existing patio?

Sometimes, if the existing base is sound and has a fall. More often we take the old surface out and build the frame from scratch so the deck drains properly and does not rock.

How much does composite decking cost?

Most composite decks we build land between £4,000 and £12,000. Size, height, frame choice and access move the number. Every price is fixed in writing after a site visit.

What guarantee do you offer?

Our workmanship is guaranteed and the boards carry their manufacturer warranty. Because our own crews build the frame and lay the boards, there is one company to come back to if anything needs attention.
