How Much Does Roughcasting Cost? (2026 Prices)
Looking for a straight answer on roughcast cost in Scotland? This guide sets out realistic 2026 prices per square metre and by house type, what pushes quotes up or down, and how to compare contractors without getting caught out by vague one-liners.
Quick answer
Expect £45–£65 per m² for wet or dry dash roughcasting in Scotland. A typical three-bed semi runs £4,000–£8,000; a detached home £7,000–£12,000. Stripping old render, scaffolding and repairs add to the base rate.
Roughcasting Prices Per Square Metre
Per-m² rates are useful for comparing systems, but they mislead on small jobs because scaffolding, access and site setup are largely fixed costs. On a full house they work better as a guide.
| Finish | Typical price (Scotland, 2026) |
|---|---|
| Wet dash roughcasting | £45–£60 / m² |
| Dry dash roughcasting | £50–£65 / m² |
| Coloured through-render systems | £60–£80 / m² |
| Patch repairs | Priced per job |
Rates usually assume sound substrate ready to receive render. Full strip-out of bossed or failed roughcast is additional labour — and often the difference between a cheap quote and a lasting job. See our roughcasting service for what a proper specification includes.
Typical Costs by House Type
| Property | Typical total |
|---|---|
| Mid-terrace | £3,000–£5,500 |
| Semi-detached | £4,000–£8,000 |
| Detached | £7,000–£12,000 |
| Bungalow | £4,500–£7,500 |
These figures generally cover labour, materials and standard scaffolding for a full elevation package. Chimneys, complex bay windows, restricted access streets and extensive masonry repairs sit outside the base range.
What Affects the Price
- Condition of existing render — stripping bossed render is labour-intensive and often unavoidable for a durable finish.
- Access and scaffolding — steep sites, shared closes, and rear elevations without vehicle access all add cost.
- Substrate repairs — cracked masonry, rotten timbers and failed sills should be fixed before new render goes on.
- Finish choice — through-coloured systems cost more up front and save repainting forever.
- Location and constraints — conservation areas, parking permits and phased occupied sites affect programme and price.
Roughcasting vs Painting Over — the False Economy
Painting failing roughcast traps moisture and typically buys two years at best. If the dash is sound, clean and dry, paint can refresh appearance — but if it's cracked or hollow, you're decorating a problem. When repairs beat full replacement we'll say so; when they won't hold, we'll explain why. For the painting debate in detail, read painting pebble dash.
How to Compare Quotes
A proper quote should include:
- Preparation specification (strip, key, repairs)
- Base coats and finish system named (e.g. K Rend)
- Scaffolding, waste disposal and making-good
- A clear workmanship guarantee
Red flags: no survey, cash-only, or a vague "re-dash walls" one-liner with no materials or prep detail. Cheap quotes that skip preparation are how bossed render returns in three winters.

Frequently Asked Questions
- Is roughcasting cheaper than smooth render?
- Traditional wet or dry dash is often similar or slightly cheaper than premium silicone systems per m². Through-coloured silicone costs more upfront but removes future painting.
- Does roughcasting add value?
- A sound, uniform exterior protects the structure, improves kerb appeal and can support saleability — especially versus cracked or bossed render.
- How long does a roughcasting job take?
- Most homes take one to two weeks once scaffolding is in place, depending on weather, stripping and repairs.
- Can I get a price without a survey?
- We can give a ballpark from photos and measurements, but a firm written quote needs a site survey.
