If you have started ringing around for prices on a raised deck, you may have had a bit of a fright. Quotes for raised and multi-level decking in Ireland can look steep next to a flat deck, and it is hard to know whether a number is fair or whether you are being chanced. This guide sets out what raised decking actually costs in 2026, why a sloped or raised build runs dearer than a flat one, and what an honest quote should have in it, so you can sense-check anything you are quoted in Louth or anywhere else.
Why a Raised Deck Costs More Than a Flat One
The first thing to understand is that you are not paying more for the same deck. A raised deck is a bigger piece of engineering than a ground-level one, and almost all of the extra cost is in the parts you never see.
On flat ground, a deck sits low on a simple frame. Lift that same deck up on a slope and you add longer posts, more of them, concrete foundations dug down to firm ground, and diagonal bracing to stop the structure swaying. Then, because it is up in the air, it usually needs steps to get onto it and a balustrade to make it safe. None of that applies to a flat deck, and all of it costs time, material and labour.
So when a raised deck comes back dearer, that is not a markup. It is the price of the structure that keeps it solid and safe for the next twenty years. You can see what goes into raised and multi-level decking in Dundalk and the full build process for the work that goes into building a deck on a slope, which is really where the money goes.
What Raised Decking Costs in 2026
Most installers price decking per square metre for supply and fit, and that rate is your starting point. As a rough guide for 2026, a flat treated-timber deck tends to start around €120 to €160 per square metre, and composite runs higher again, usually somewhere from €180 to €260 per square metre depending on the board. We keep the full base-rate breakdown on our decking cost guide for County Louth.
A raised or sloped build then adds to that, because of the extra structure above. How much depends almost entirely on the height and the steepness, so it is impossible to give one honest figure that fits every garden.
A worked example helps. Take a raised composite deck of around 20 square metres in a sloping back garden, with a short flight of steps and a run of balustrade. As a rough guide in 2026 you might be looking at somewhere in the region of €5,000 to €8,000, with a timber version coming in less, perhaps €3,500 to €6,000. The figure moves with the board you choose, how high the deck sits, the state of the ground and how easy it is to get materials in. The only number that actually means anything is a written, itemised quote for your specific garden.
What Should Be in the Price
This is where people get caught out, so here is what a complete raised decking quote should already include, and the extras to watch for:
- Foundations and subframe. The concrete footings, posts and bracing. This is the bulk of a raised deck and should never be a vague line.
- Steps. A flight of steps typically adds a few hundred euro, often in the €300 to €800 range depending on width and material. On a raised deck you almost always need them, so they should be in the quote, not sprung on you later.
- Balustrades and handrails. Priced by the linear metre and listed separately. A raised deck above the regulation height needs them, so check they are costed in.
- Old-deck removal. If there is an existing deck to take out, taking it away and disposing of it should be in the price.
- Site clearance and cleanup. Spoil from the foundations and offcuts taken away, the site left tidy.
It is worth knowing your rights here. The Competition and Consumer Protection Commission advises getting a written quote rather than an estimate, because a written quote is legally binding while an estimate has no such standing, and asking for a full breakdown of all costs before any work starts. That single step heads off most of the horror stories.
Why Two Quotes for the “Same” Deck Look So Different
It is common to see a composite deck of around twenty-something square metres with a railing quoted close to ten thousand euro, and a homeowner left wondering if that is normal. Sometimes it is, sometimes it is high. The honest answer is that without the detail you cannot tell, and that is exactly the problem.
A quote can swing by thousands depending on whether the ground needs digging out, how high the deck sits, whether a premium board or a budget one is being used, how much railing is involved and whether removal is included. Two installers can quote the “same” 20 square metre deck and be pricing two completely different jobs. The cheapest is not the best value, and the dearest is not always a rip-off. What tells you the truth is the breakdown, not the bottom line.
Getting an Honest Raised Decking Quote in Louth
We do not put a flat figure online because no two sloping gardens in Louth are the same, and a number plucked off a website would only mislead you. What we do instead is come out, look at the fall of the garden and the ground conditions, and give you a fixed, written, itemised price with the foundations, the frame, the steps, the railings and the removal all listed. The price you hear is the price you pay.
Seamus and Pete have been pricing and building raised decks across Dundalk and the Louth towns for over thirty-five years, so the quote you get is based on what the job actually takes, not a guess.
If you have a sloped garden and want to know what a raised deck would really cost, the quickest way is to get a proper look at it and a written price you can rely on. No vague estimates, no surprises at the end.
