Why composite works on the coast
Uncapped or early composite boards could absorb water, stain and grow mould. Modern capped boards are wrapped in a hard polymer shell that keeps moisture and salt out. That makes them a good match for Redcar's climate: they don't rot, crack or splinter, and they don't need the yearly staining that timber does.
Choosing boards for salt and sun
Not all composite is equal. Near the sea we look for boards with strong UV stability, a dense cap and a good textured grain for grip when wet. Lighter shades like driftwood grey and sand reflect heat, stay cooler underfoot and fit the coastal palette. Darker boards can look striking, but they warm up more in summer and show salt residue more readily.
Stainless steel, always
The clips and screws matter as much as the boards. On every coastal deck we use stainless steel hidden clips and screws, so there's no rust streaking across the boards and no fixings failing early. Joist hangers and brackets are chosen for coastal use too.
A frame that dries out
Salt and damp linger where air can't move. We space joists closely, leave the gaps composite makers specify, and keep the area under the deck open to the air, with membrane and gravel to stop weeds and sand sitting on soil. Water drains away instead of collecting.
Looking after it
A rinse with fresh water every few weeks in summer, and after storms, washes off salt and sand. A soft brush and mild soapy water once or twice a year does the rest. No staining, oiling or sanding.
FAQs
Which composite boards cope best by the sea?
Fully capped boards with good UV resistance and a textured surface. We'll bring samples that have proved themselves on coastal jobs and explain the differences.
Will composite go chalky in strong sun?
Good capped boards are designed to resist it, and any change is slow and even. Rinsing off salt regularly helps keep the surface looking fresh.
