Silicone Render cost in Kent: 2026 Price Guide

26 Aug

If you're pricing up silicone render for a house in Kent, you can expect to pay roughly £65–£95 per m² fully installed (materials and labour), or £7,500–£13,500 for a typical three-bedroom semi-detached home. Detached properties usually run from £13,000–£19,000+, while mid-terraces start around £4,500–£6,500. Exact pricing depends on wall area, the condition of your existing walls, scaffolding needs, and whether a full basecoat system is required.

Below, we break down exactly what drives that price, what's included, how it compares to other render types, and what to watch out for when comparing quotes from Kent rendering contractors.

Average silicone render cost by property type (Kent, 2026)

  
      Property type
      Approx. wall area
      Typical installed cost
    
      Mid-terrace (2 exposed walls)
      50–70m²
      £4,500 – £6,500
    
      Semi-detached (3 exposed walls)
      90–120m²
      £7,500 – £13,500
    
      Detached house
      130–180m²
      £13,000 – £19,000+
    
      Bungalow
      60–90m²
      £5,500 – £9,500

Property type	Approx. wall area	Typical installed cost
Mid-terrace (2 exposed walls)	50–70m²	£4,500 – £6,500
Semi-detached (3 exposed walls)	90–120m²	£7,500 – £13,500
Detached house	130–180m²	£13,000 – £19,000+
Bungalow	60–90m²	£5,500 – £9,500

These figures include surface preparation, primer, the silicone topcoat, and standard scaffolding for a two-storey property. They assume the existing substrate is in reasonable condition — if walls need extensive repair or a full basecoat system, costs will sit toward the upper end or above this range.

What affects silicone render cost in Kent?

Wall condition and prep work. If your existing render or pebbledash needs removing before the new system goes on, this adds both labour time and disposal costs. Sound existing render can often be rendered straight over, which keeps costs down.

Basecoat requirements. Silicone can be applied as a standalone topcoat over a well-prepared, primed substrate. But on older brick, block, or where extra impact resistance is needed, a fibreglass-reinforced basecoat goes underneath first — this is a different, more involved system and costs more per m².

Scaffolding and access. A two-storey terrace or semi typically needs £800–£1,800 of scaffolding. Detached properties, awkward access, or homes near boundaries and shared walls can push this higher.

Property type and layout. Bay windows, dormers, multiple gable ends, and decorative detailing all add labour time compared with a simple flat-fronted wall.

Colour and texture. Standard colours from the manufacturer's palette are included in most quotes. Bespoke colour matching or unusual textures can add a small premium.

Where you are in Kent. Labour rates vary modestly across the county — coastal towns like Herne Bay and Broadstairs can involve extra prep for salt exposure, while properties in conservation areas (parts of Sevenoaks, Tonbridge, and Canterbury) may need planning considerations factored into the project timeline, though not usually the render cost itself.

Silicone costs more upfront than traditional sand and cement, but it doesn't need repainting — cement render typically needs a fresh coat of masonry paint every 5–10 years, which adds up over the render's lifetime. Over a 20-year period, silicone often works out cheaper overall once you factor in redecoration costs for painted finishes.

Is silicone render worth the cost?

For most Kent homeowners, yes. The main reasons silicone render commands a higher price — and why it's now the most requested finish we install — are:

It's flexible. It moves with the building through seasonal expansion and contraction, so it resists the hairline cracking that affects cement render.
It's hydrophobic. Water beads and runs off rather than soaking in, which protects the wall structure and reduces algae and staining.
It's self-cleaning and colour-stable. Rain washes surface dirt away, and the colour is mixed through the material rather than painted on, so it won't fade or need repainting for 20–30 years.
It's breathable. Moisture vapour can still escape from the wall, which matters for older Kent properties — Victorian and Edwardian solid-wall houses in particular need a breathable system to avoid trapping damp.

Getting an accurate quote

Online cost guides can only give you a ballpark. The real number for your property depends on an on-site survey — wall condition, access, and exact measurements all move the price. A reputable Kent rendering contractor will:

Inspect the existing substrate before quoting, not just from photos
Confirm whether you need a basecoat system or a straight topcoat
Include scaffolding, waste removal, and VAT in the written quote (not just a headline day-rate)
Offer a manufacturer-backed or insurance-backed guarantee on the finished system

Frequently asked questions

How much does silicone render cost per m² in Kent?
Expect £65–£95/m² fully installed for a straightforward job on a sound substrate. Add a basecoat system and costs typically rise to £85–£130/m².

Is silicone render more expensive than K Rend or monocouche render?
Slightly, yes — silicone usually sits £10–£15/m² above monocouche systems like K Rend, largely because of its self-cleaning, hydrophobic properties and wider colour range.

Does silicone render cost include scaffolding?
A properly itemised quote should include scaffolding for a standard two-storey house. Always check what's included before comparing quotes on price alone.

How long does silicone render last?
20–30 years with minimal maintenance, when installed correctly over a well-prepared substrate.

Can I get a fixed price without a site visit?
Only as a rough guide. Wall condition, exact measurements, and access can't be judged accurately from photos alone, so a genuine fixed quote needs a site survey.
