Can You Repair Render? What UK Homeowners Need to Know | HouseRenderPro

Yes, Render Can Be Repaired! – Here's How

Over 80% of damaged render doesn't require full replacement – including silicone, monocouche, K Rend, pebble dash and traditional scratch coat. As George Edward (17 years' UK rendering experience) confirms:

*"Professional patch repairs cost 60–80% less than re-rendering and extend your finish's life by 10–15 years. The key is matching the repair to your specific render type."*

Here's your complete guide to render repairs in 2025:
