How to hire a deck building & repair pro in Ireland
- Find installers with verifiable reviews (Onlinetradesmen, local recommendations) — no licence exists for decking in Ireland
- Check planning: decking raised significantly above ground level or in front gardens may need planning permission; most low garden decks are exempt development
- Ask for public liability insurance
- Confirm treated timber grade for the sub-frame and a ground membrane
- Get a written quote separating sub-frame, boards, balustrade and waste removal
- Ask about slip resistance — grooved or composite boards suit the wet Irish climate
Most ground-level garden decking in Ireland is exempt development, but raised platforms that overlook neighbours can require planning permission. There is no statutory licence for deck installers, so insurance and references are the vetting tools.

Frequently asked questions
How often should a timber deck be stained or oiled?
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.
What should a deck quote include?
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.
How do I vet a deck builder in Dublin?
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 Dublin, also check any licence or registration your local rules require for structural outdoor work before signing.
What deck size do most homeowners build?
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.
How much does it cost to build a deck?
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.
Composite vs timber decking — which is cheaper long-term?
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.
How long does a deck build take?
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.
Does decking make sense in the Irish climate?
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.
