Deck Building & Repair in South Dublin

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.

Usually yes once the deck is raised above a threshold height or attached to the house — the exact trigger varies by jurisdiction. Ground-hugging platforms are often exempt. A good deck builder in South Dublin will know the local threshold and handle the application; be wary of anyone who says permits never apply.

Ask for photos and addresses of decks built 3+ years ago (new decks all look good), proof of insurance, and whether they or a subcontractor do the footings. In South Dublin, also check any licence or registration your local rules require for structural outdoor work before signing.

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.

Timber is cheaper to install but needs sanding, staining or oiling every 1-3 years. Composite costs 50-100% more upfront but only needs washing. Over 10-15 years the totals often converge, so the decision usually comes down to upfront budget and how much maintenance you will actually do.

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.

Yes, but algae and slip are the main issues — grooved boards, annual washing and anti-slip treatments matter more than in drier climates. Composite boards have grown popular for this reason despite the higher upfront cost.
