The most common decking complaint is not about the wood. It is about the bill. Someone is quoted one figure, the work starts, and a string of extras appears that nobody mentioned at the outset: steps, railings, taking the old deck away, a bit of levelling. The hidden costs with decking are rarely a scam. More often they are things a vague quote simply left out, so they land on you at the end when it is too late to plan for them. The fix is knowing what those extras are before you sign anything, and knowing what a proper quote should already cover. Here is the full list.
Why Decking Bills End Up Bigger Than the Quote
There is a real difference between an estimate and a quote, and it matters more than most people realise. An estimate is a rough guess that can move. A quote is a firm price for clearly defined work. If you only ever get a verbal “ah, it’ll be around four grand”, you have nothing to hold anyone to when the final invoice says five.
This is not a small problem in Ireland. The State’s consumer watchdog reported that home improvement issues were one of the biggest drivers of complaints to its helpline, with consumers spending an average of close to €15,000 on jobs that later went wrong. Its standing advice is blunt: get a written quote rather than an estimate, because a written quote gives you far stronger rights if the bill does not match what you were told. The CCPC’s guidance on hiring tradespeople is worth reading before any garden job. Almost every decking horror story starts with a price that was never written down and never itemised.
The Extras That Don’t Always Make It Into a Quote
These are the line items that turn a tidy headline figure into a nasty surprise. None of them is unreasonable to charge for. The problem is when they are left off the quote rather than listed on it.
- Steps. The single biggest one. Each step run adds roughly €300 to €800 depending on the width and the material, because steps are slow, fiddly work compared with laying a flat surface.
- Railings and balustrades. A safety requirement on any raised deck and a real cost in both materials and labour. Always ask whether the quote includes them.
- Removing the old deck. Tearing out and disposing of an existing deck takes time and usually means skip hire. This is one of the most commonly omitted items, and it is exactly why we include having an old deck removed and replaced in Dundalk as part of the job rather than a surprise at the end.
- Ground preparation. Uneven, boggy or previously concreted ground may need levelling, drainage or excavation before a frame can go down. A quote given without anyone looking at the ground cannot account for this.
- Access. A van that cannot get near the garden, or materials that have to be carried through the house, adds labour and often floor protection. Difficult access quietly inflates a lot of trade quotes.
- Fascia, skirting and finishing. Closing in the sides of the deck so the frame is not on show is sometimes quoted as an extra rather than assumed.
- Lighting. Integrated deck lighting is a separate cost, both the fittings and the wiring.
- VAT. A contractor’s supply-and-fit decking job is normally charged at the reduced 13.5% VAT rate that applies to construction work in Ireland. The trap is a price quoted before VAT. Always confirm the figure you are given is the VAT-inclusive total.
What an Honest Itemised Quote Already Covers
Here is the other side, and it is the part that separates a fair installer from a cheap-looking one. A proper supply-and-fit quote should already include, as standard and not as extras:
- The structural subframe, the timber skeleton the whole deck depends on
- The decking boards, fixed and finished
- A weed membrane underneath
- Basic cleanup of the work area
When the subframe is quietly stripped out of a quote to make the per square metre rate look keener, that is the most expensive hidden cost of all, because it is the part that fails first. The honest way to compare two quotes is to put them side by side and check they include the same things, which is far easier once you start comparing quotes by the square metre. If one quote is missing the subframe detail, the removal, or the steps, it is not cheaper. It is just less finished. For the full picture of how we price decking across County Louth, the rule is simple: everything you will be charged for is on the page before we start.
Do You Need Planning Permission for Decking in Ireland?
This is the worry people assume will become a hidden cost, and for most gardens it does not. A standard low or ground-level deck in a back garden is normally exempted development, meaning no planning permission and no fee. It only becomes a planning question in two situations: a substantially raised deck that lifts the ground level well above the neighbouring ground, or a deck that could overlook a neighbour and affect their privacy. In those cases the safe move is a quick check with Louth County Council before you build, and Citizens Information sets out the basics of exempted development and when permission is needed. Building regulations on safe guarding for raised decks still apply separately, which is the proper reason a tall deck needs railings.
We work right across Dundalk, Blackrock, Carlingford, Ardee and the rest of County Louth, and we quote the same way every time: in writing, itemised, with the steps, railings and old-deck removal listed so nothing appears at the end that was not there at the start.
