Stone cladding cost: what you pay for
Why one m² of cladding can cost very different amounts, how to work out quantities without over-ordering, and what to budget for beyond the stone.
Ask what stone cladding costs per m² and the honest answer is: it depends on more than the stone. Two walls the same size can come out very differently once the format, the wastage, the fixing and the finish are counted.
Here is what goes into a cladding quote — ours or anyone’s — and how to work out quantities so you order enough, without paying for crates you don’t need. Not sure which format you want yet? Start with the types of stone cladding.
What sets the cost per m²
-
The stone and colour
Slate, quartzite and Lesotho sandstone each have their own price, and so do the colours and selections within each range.
-
The format
Riven strips, interlocking panels, drypack, building stone and random cladding are prepared differently. The more the stone is prepared before it reaches you, the quicker it is to fix; split building stone and random formats take more of your stonemason’s time.
-
Coverage and packaging
Riven strips are packed 1 m² per level and panels are boxed with a fixed coverage, so you buy the area you need. Building stone and random formats are supplied by the pallet.
-
Wastage
Allow about 10% extra for cuts, corners and pieces you won’t use. Walls with many corners, pillars and openings can need a little more.
-
Fixing and labour
The adhesive and the installer’s time depend on the format and on the wall itself — what it is built from, and whether it is inside or out. Tell us about the wall and we’ll advise.
-
Sealing
Sandstone and slate on outside walls should be sealed to keep water marks and staining off the surface, so budget for a sealer such as Water Block.
-
Delivery
Collect from our Northriding warehouse in Randburg, or we deliver palletised stone to site on our own fleet — across Gauteng and to every province.
How much cladding do you need?
- Measure the width and height of each wall in metres, and multiply them for the area in m².
- Subtract windows, doors and any other openings.
- For pillars and columns, measure every face you will clad and add them up.
- Add about 10% for cuts and corners.
- Convert to packs: riven strips are 1 m² per level; for panels, divide by the coverage per box and round up.
A wall 4 m wide and 2.7 m high is 10.8 m². Add 10% and you need about 11.9 m² — that’s 12 levels of riven cladding, 19 boxes of Verona panels at 0.63 m² each, or 27 boxes of Jasper at 0.45 m² each.
