Deck Building & Repair in Dún Laoghaire

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.

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 Dún Laoghaire, also check any licence or registration your local rules require for structural outdoor work before signing.

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 Dún Laoghaire will know the local threshold and handle the application; be wary of anyone who says permits never apply.

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.

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.

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.

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.
