An Indian sandstone patio in the UK typically costs between £2,000 and £6,000 installed. It sits between budget concrete paving and porcelain on price, which is a good part of why it's been the default choice for British gardens for the best part of two decades. Two things in a sandstone quote catch people out, though, and neither is the slab price: whether the stone is calibrated, and whether sealing is included.
Indian sandstone patio cost by size
These are installed prices for Indian sandstone patio installation — excavation, sub-base, laying, jointing and finishing, not the slabs on their own.
Typical UK installed prices. Actual quotes vary by stone grade, slab thickness, access and whether sealing is included.
| Job size | What's usually involved | Typical cost |
|---|---|---|
| Small sandstone patio, up to around 15m² | A seating area in a single size or simple mixed pattern, calibrated stone, straightforward access | £2,000 – £3,300 |
| Medium sandstone patio, around 15–30m² | A full garden patio, mixed-size pattern, edging and falls designed in, sealing usually included | £3,300 – £4,700 |
| Large sandstone patio, 30m²+ | Larger area, premium colour or thicker hand-cut stone, steps or circle features, drainage work | £4,700 – £6,000+ |
That works out at roughly £130 to £200 per square metre installed — above a general patio installation in concrete flags, and below the £165 to £230 that porcelain typically runs to. The patio installation cost guide and the porcelain patio cost guide have the comparable breakdowns.
Calibrated or hand-cut: the cost driver nobody quotes for
Indian sandstone is a natural, quarried stone, and it doesn't come out of the ground at a consistent thickness. What happens next is where a lot of the price difference between two similar-looking quotes lives.
- Calibrated stone has been machine-ground on the back to a consistent thickness, usually around 22mm. It costs more per square metre, but it lays fast and evenly because every slab sits on the same depth of bed.
- Uncalibrated, hand-cut stone varies — often anywhere from 15mm to 35mm within the same pack. It's cheaper to buy, and it's genuinely lovely stone, but the installer has to adjust the mortar bed under every single slab to bring the faces level. That's slower, and on a decent-sized patio it can add the best part of a day.
Neither is wrong. What matters is that the quote and the stone match: a price based on calibrated stone laid on uncalibrated stone either overruns or ends up with an uneven surface. If two sandstone quotes are a few hundred pounds apart, this is the first thing worth asking about.
Sealing is a line item, not an optional extra
Sandstone is porous. Unsealed, it takes up water, tea, barbecue grease and leaf tannins readily, and it's more prone to algae and to the slow fading that shows up first on lighter colours. Most installers either include sealing in the job or offer it as an add-on, and it's worth having either way — but it should appear on the quote as its own line so you can see what you're getting.
Ask how many coats are included and what product is used. Ask, too, whether the quote covers the initial seal only. Sealing is not a one-off: a sandstone patio typically needs resealing periodically to keep working, which is the main running cost of choosing natural stone over porcelain.
What else moves a sandstone quote
- Colour and grade. Buff and mixed 'autumn' blends are the volume products and sit at the bottom of the range. Consistent greys, blacks and the cleaner premium grades cost more per square metre.
- Slab thickness. Thicker stone costs more to buy, weighs more to move and needs a deeper build-up.
- Pattern. A single-size layout is quick. A mixed-size patio pattern takes planning and more cutting, and a circle feature or a fanned edge takes more again.
- Sealing. Whether it's included, how many coats, and whether it's repeated after the joints have cured.
- Ground conditions and access, as with any patio — soft ground means a deeper sub-base, and no side access means every pack of stone comes through the house.
Sandstone joints are usually wider than porcelain ones, and whether they're filled with mortar or a brush-in compound affects both the price and how the patio ages. It also affects what maintenance looks like later — washed-out joints are the most common reason a sandstone patio needs repointing a few years in. Get the jointing method named on the quote.

Frequently asked questions
Does Indian sandstone need sealing?
It's generally recommended. Sandstone is porous, so unsealed stone is more prone to staining, algae growth and colour fading over time. Most installers include sealing as part of the job or offer it as an add-on, and it typically needs repeating periodically rather than being a one-off treatment.
Why are some Indian sandstone quotes so much cheaper?
Usually one of three things: uncalibrated rather than calibrated stone, sealing excluded, or spoil removal excluded. All three are legitimate ways to quote, but they aren't like-for-like with a quote that includes them. Ask each installer to confirm which of the three applies before comparing prices.
How long does an Indian sandstone patio last?
With proper installation and periodic resealing, twenty years or more is realistic. Natural stone tends to weather gracefully rather than simply looking worn out, though the joints usually need attention long before the slabs do.
Is Indian sandstone slippery when wet?
Riven sandstone has a naturally textured surface that generally gives good grip when wet. A sawn or heavily sealed finish can be smoother, so it's worth asking your installer about slip resistance if the patio will be a main route to the door or gets little sun.
