Deck Building & Repair in Wales

Every 12-24 months for oil finishes and 2-4 years for film-forming stains, depending on sun exposure. Re-coating on schedule is the single biggest factor in how long the boards last.

Deck cost is driven by area, height off the ground, and material. Ground-level softwood decks are the cheapest; elevated decks need engineered footings and balustrades, and composite or hardwood boards can double the board cost. Most quotes are priced per square metre or square foot, with stairs, balustrades and lighting as line items.

If the frame (joists, bearers, posts) is sound, boards and balustrades can be replaced individually and the structure re-stained for a fraction of a rebuild. If posts are rotting at the base or the ledger connection to the house is corroded, replacement is usually safer and not much more expensive than piecemeal repair.

The most common residential decks fall between 12-25 m² (130-270 sq ft) — enough for a table, chairs and a grill. Costs do not scale perfectly with area: small decks carry fixed costs (access, footings, delivery), so price per square metre drops as size grows.

A simple ground-level deck takes 2-4 days. An elevated deck with footings, stairs and balustrades typically takes 1-2 weeks, plus any permit or inspection lead time before work can start.

A complete quote lists demolition/removal of any old structure, footings, framing timber and spans, board type and grade, fixings (hidden vs face-screwed), balustrades, stairs, waste removal, and whether permit fees and engineering are included. Missing line items are where cheap quotes grow.

Spring and early autumn — installers are cheapest and most available outside the May-July rush, and timber should not be oiled or stained in frost or on wet boards. Winter builds are possible but ground conditions slow footing work.
