Installation Guide

A professional-finish composite deck can be installed by a competent DIYer over a weekend.

1

Plan and measure your area

Mark out your deck area and calculate the total square meterage. Add 10–15% for cuts and wastage.

💡 Order free colour samples first to see boards in your garden's natural light
2

Prepare the sub-frame

Install pressure-treated C24 timber or aluminium joists on a firm, level base. Joist spacing must not exceed 400mm centre-to-centre for perpendicular boards, 300mm for diagonal laying.

💡 Leave 5–10mm ventilation gap beneath the deck for airflow and drainage
3

Lay the first board

Start at the most visible edge or against the house wall. Allow a 5mm gap from any fixed structure. Use the supplied starter clips — slot into the board's groove and screw into each joist.

4

Continue laying boards

Press each board firmly into the previous clips, then add middle clips to the exposed groove. Check alignment every 3–4 boards. Stagger butt joints by at least 600mm across rows.

💡 End-to-end gap should be 5mm per metre of board length for expansion
5

Cut and finish edges

Use a fine-tooth circular saw with the cut side face-up. Seal cut ends if the deck will be exposed to standing water at that edge.

6

Add trims and fascia

Finish exposed edges with matching fascia, corner trims, and skirting. Fit edge boards using stainless screws colour-matched to your boards.

💡 Wash with soapy water once installed — no oiling, sealing, or treatments needed

Frequently asked questions

Each panel covers 1.83m of horizontal run. Measure your boundary, divide by 1.83 and round up. Add one extra post compared to panels (e.g. 5 panels need 6 posts).
Yes — order up to 6 free colour samples delivered within 3–5 working days. Strongly recommended for matching to existing garden features.
Yes — our composite fencing is engineered for 60mph+ winds when correctly installed on concreted posts. Boards slot into post channels, distributing wind load rather than catching it.
Yes — the Deluxe Composite Gate matches the Deluxe fence range exactly. Hinges, latches, and reinforced gate posts are included.
For posts, yes — post-mix or concrete is essential for stability. The fence itself does not need a concrete footing along its length: a 25mm gap at the base for drainage is preferred.
In-stock items dispatch within 48 hours. Standard UK delivery takes 3–5 working days for fence kits. Free delivery on orders over £1,000.
Aluminium bolt-down posts for hard ground (concrete, slabs, deck). Composite concrete-set posts for soft ground. Both types come with matching caps to finish the run.
