More time enjoying, less time maintaining. Contemporary, weather-ready decking without the oiling. A free visit lets a local installer understand your priorities, check practical details and recommend a specification that suits both the garden and your budget. You will receive a fixed written quote for the agreed scope, with no obligation to go ahead.
Capped or uncapped boards?
Capped boards have a protective outer layer that helps resist stains and moisture. Uncapped products leave the composite material exposed and can require a different cleaning routine. Compare the actual manufacturer specification rather than assuming every composite board performs identically. A capped, mid-range product is often a sensible starting point for a Scottish garden. Ask to see samples outdoors, where colour and texture look different from showroom lighting. A wood-grain finish can feel more natural beside a sandstone house, while a plain contemporary finish suits a restrained modern garden.
Hollow and solid cores
Hollow boards can be lighter and less expensive, while solid-core products may suit exposed edges or certain demanding applications. Neither description alone guarantees quality. The manufacturer sets the permitted spans, fixing system and suitability for steps or raised structures. Ends may need matching caps or fascia boards. Your installer should explain which parts of the design will remain visible and how those edges will be finished. Comparing complete systems avoids choosing an attractive board only to discover that matching trims or suitable stair details cost extra.
The subframe and fixing system
Composite boards still need a well-built supporting structure. Timber, composite and aluminium subframes each have suitable uses; the right choice depends on the site, product and budget. Hidden-fix clips keep the surface neat, but must allow the specified expansion gaps. Joist spacing, edge support and ventilation are all important. A low-maintenance board installed over a poorly ventilated, deteriorating frame will not give a low-maintenance deck. Ask whether the quoted price includes foundations, joists, membrane, clips and finishing trims, and whether every component follows the board manufacturer’s installation guidance.
Living with composite in Scottish weather
Composite does not need oiling, is generally splinter-free and avoids timber-board rot, making it attractive in wet conditions. It is not maintenance-free: leaves, mud and algae still need removing, and drainage channels should stay clear. Use the manufacturer’s recommended cleaning method rather than an aggressive pressure setting. Boards can become warm in direct sunshine, particularly darker colours, and some colour change may occur. Slip resistance varies by product and surface condition. Check published product information and choose a finish appropriate to steps, shaded corners and regularly wet areas.
Lifespan, warranties and long-term value
Many manufacturers offer warranties in the 10–25 year range, but coverage, exclusions and installation conditions differ. A warranty is not a promise that every part of the deck will last equally long or that accidental damage is covered. Keep the product details and maintenance instructions after handover. Composite usually costs more initially than softwood; its appeal is reduced upkeep over time. For a household that would otherwise pay for repeated sanding and oiling, that difference can be worthwhile. Compare the complete installed cost and likely care needs, not the board price alone.

Discuss the whole project
If the work involves more than one part of the garden, tell the installer at the first visit. Fencing, paving, garden design and decking often need to be planned together so access and drainage still work. Ask about product care, insurance and workmanship terms before accepting the quote. Partners carry out and are responsible for their own installation work.
