How much stone carpet costs per m² (2026 guide)

The price of a stone carpet floor cannot be settled over the phone with a single figure, and be wary of anyone who does so without seeing your floor. The real cost depends on your specific case: on the metres, the state of the substrate and the finish you choose. What we can do —and it is honest— is explain what it depends on so you reach the quote knowing what you are paying for and why.

What the price depends on

Stone carpet is priced per m², but that price per metre is not fixed: it shifts with several factors.

• The total m². The larger the area, the better the price per m² usually works out: fixed costs (travel, kit set-up, waste) are spread across more metres. A small pool or a landing has a higher price per m² than a large patio.
• The colour and type of aggregate. Not all aggregates cost the same. The origin of the stone, the colour and the grain size influence the price of the material. A premium aggregate or a specific colour can push up the price per m².
• The state of the substrate. This is the factor that varies most from one job to the next. A sound, flat, well-bonded floor needs little preparation. One with loose tiles, cracks, uneven levels or damp demands prior work (repairing, levelling, treating) that adds to the quote. It is not an optional extra: it is what makes the job last.
• The system thickness. Depending on the use (pedestrian, pool edge, vehicle traffic) one thickness or another is applied, and that changes the quantity of material.
• Access to the site. Getting the material and the kit to the area is not the same in a ground floor with direct access as in a top-floor flat with no lift or a plot that is hard to reach. Logistics has an effect.
• The type of resin and the finish. The binder decides much of the behaviour (UV, outdoors) and of the price. A sun-stable aliphatic resin does not cost the same as a basic one.

Indicative range per m²

. This article does not publish a figure of our own without the craftsman validating it. We give the factors and settle the price after the visit; we would rather not give you a number we cannot then stand behind.

Market guidance (this is not our quote): various installers and public sector information place outdoor stone carpet installation in a broad range that varies greatly depending on the state of the substrate, the thickness and the area. It is only a reference so you know what order of magnitude you are dealing with; your real price only comes out after seeing your floor.

Why a cheap quote can end up expensive

When a quote is well below the rest, almost always something has been cut where it does not show: in the substrate preparation. It is the stage that decides whether the surface holds or lifts, and the one that takes the most labour. Good aggregate over a poorly prepared substrate ends up coming away, and then it has to be redone, which works out far more expensive than having done it well the first time.

Other ways of cutting corners that you pay for later: using less thickness than the use calls for, a lower-quality resin that yellows or degrades in the sun, or skipping the treatment of existing damp. Cheap, in outdoor flooring, is usually a down payment on the next job.

What an honest quote includes

A clear quote should set out, as a minimum:

• Substrate preparation: cleaning, crack repair, levelling and damp treatment if there is any.
• Priming and material: the bonding coat, the aggregate (with its colour and grain size) and the resin.
• Labour and finish: the application and the finishing.
• What it does NOT include: putting in writing what is left out avoids surprises (e.g. major civil works, drains, removal of a complete tiled floor).

If it all goes on a single line of “flooring, X €”, ask them to break it down: in this trade, detail is a sign of seriousness.

Frequently asked questions

Can you give me a price by WhatsApp?

We can guide you on the order of magnitude, but the firm price we give after seeing your floor: the state of the substrate changes the result so much that giving a figure blind would be misleading you.

Why does the price vary so much between quotes?

Because they do not all include the same things. Two quotes can look identical and one allow for substrate preparation while the other does not. Compare what each one includes, not just the final number.

Is it cheaper than breaking up and re-tiling?

Often yes, because stone carpet is applied over the existing floor and you save the cost of lifting the tiling, the rubble and its removal. We look at it in renovating a patio without building works.

Is the price for a pool edge different from a patio?

It usually is: a pool edge requires a carefully done non-slip finish and a good resolution of the drainage and the fall, which can influence the price. We cover it in the best paving for a pool edge.
