What is House Rendering?
House rendering is the process of applying a protective and decorative coating to the exterior walls of a building.
It serves two main purposes:
- Protection – shielding your walls from wind, rain, and frost.
- Aesthetics – improving kerb appeal and creating a clean, modern look.
In the UK, rendering is popular for both new builds and older homes needing an exterior makeover.
How Does Rendering Work?
Rendering involves applying a specially formulated mixture (cement-based, lime, or polymer) over brick, blockwork, or concrete. The render is then smoothed, textured, or coloured to achieve the desired finish.
Typical process:
- Preparing the surface (cleaning, repairs, or removing old finishes)
- Applying base coats (if required) with mesh reinforcement
- Adding the top coat render (monocouche, silicone, acrylic, etc.)
- Finishing with smoothing, texturing, or decorative detail
Main Types of House Rendering in the UK
1. Monocouche Render
A through-coloured, cement-based render applied in a single coat.
- ✅ Low maintenance
- ✅ Available in multiple colours
- ⚠️ Less flexible than silicone
2. Silicone Render
A modern, polymer-based render known for flexibility and self-cleaning properties.
- ✅ Long-lasting (20–25+ years)
- ✅ Crack-resistant and water-repellent
3. External Wall Insulation (EWI)
Insulation boards fixed to the exterior walls, finished with render for both energy efficiency and aesthetics.
- ✅ Reduces heating bills
- ✅ Improves comfort year-round
Benefits of Rendering Your Home
- Weather protection – keeps water out, prevents frost damage.
- Energy efficiency – especially when combined with EWI.
- Kerb appeal – transforms tired exteriors into modern, attractive homes.
- Low maintenance – modern renders resist dirt, algae, and cracking.
- Increased property value – a fresh, modern finish boosts market appeal.
How Much Does House Rendering Cost?
Costs depend on the type of render, property size, and preparation required.
| Type of Render | Cost per m² | Average 3-Bed Semi |
|---|---|---|
| Silicone Render | £70–£85 | £6,000–£8,000 |
| Monocouche Render | £60–£70 | £5,000–£7,000 |

How Long Does Rendering Last?
- Monocouche: 15–20 years
- Silicone: 20–25+ years

Regular cleaning can extend the life of your render significantly.
