How Much Does Render Repair Cost in the UK? (2025 Guide)

If your property has cracked, damaged, or blown render, you're probably wondering: how much does render repair cost in the UK? The answer depends on the type of render, extent of the damage, and whether you're doing a small patch or full wall repair.

In this guide, George Edward from HouseRenderPro breaks down the real-world costs of render repairs in 2025 — including price per m², common job examples, factors that affect cost, and when it’s time to re-render instead.

Average Render Repair Cost (UK 2025)

George says: “If the damaged render is under 2m², a patch repair is usually affordable. For bigger jobs, re-rendering often makes more sense long term.”

What Affects the Cost of Render Repair?

Several factors can push the price up or down:

1. Size of the Damaged Area

• Larger sections cost more due to extra materials and time.

2. Type of Render

• Cement render is cheapest to repair.

• Silicone render requires colour matching and specialist products.

• Pebble dash costs more due to aggregate and labour.

3. Access & Height

• Work above 2-storeys or over conservatories may need scaffolding (£300–£600 extra).

4. Preparation Required

• Loose or blown render must be chipped away.

• Damp areas may need treatment or breathable repair mortars.

5. Finish Matching

• Texture, colour, or dash stone matching adds to labour and cost.

George’s Tip: “Matching an old render isn’t just about colour – it’s about texture and technique too. Budget a bit extra for blending.”

Is It Cheaper to Repair or Re-render?

George says:

“If your wall’s got more than 3 or 4 repairs in different places, re-rendering can actually be more cost-effective and will look far better.”

Can I DIY Render Repairs to Save Money?

✅ Yes – for small cracks or touch-ups, confident DIYers can save £100–£300 using ready-mix repair mortar or masonry filler.

❌ No – for blown render, pebble dash, or silicone finishes, you’ll need professional tools, experience, and materials for a proper job.

George’s Warning: “Bad repairs stand out. I’ve fixed DIY patches that actually cost more in the long run.”
