Silicone Render — what you need to know
Silicone render is the most widely specified modern exterior render system — a polymer-modified, through-coloured finish that is both hydrophobic and breathable. The silicone chemistry makes the surface self-cleaning: rainwater beads and runs off rather than soaking in, carrying surface dirt with it. The colour is carried through the render depth, so there is no surface paint to chip or fade. Manufacturer-backed system warranties are available on qualifying installations. It is suitable for most residential properties in Yorkshire and is our most popular system.
Solid-walled Victorian terraces in Heworth rely on external render for weather protection — failed render on these properties allows rain to penetrate directly through the masonry. Silicone render is increasingly used for re-render projects in the area.

Solid brick or stone Victorian properties where the original sand-cement render has reached end of life and needs replacing with a breathable silicone system
Dated pebbledash or roughcast that is beyond repair and needs replacing with a clean modern finish
Cracked, stained or failing render letting moisture into the masonry behind
Properties where the exterior needs refreshing cosmetically and weatherproofing structurally
Houses where EWI is being installed and a silicone finish coat needs specifying over the insulation boards
Property considerations in Heworth
Heworth is an established east York suburb with a high proportion of Victorian terraced and Edwardian semi-detached properties, particularly on the streets running north and south of Heworth Road. Many of these properties are of solid brick masonry construction. The area was developed largely to house workers from the Rowntree's factory (now the Nestlé site) in the late 19th and early 20th century, and retains a cohesive Victorian residential character. Heworth Green is the main road running south-east towards Layerthorpe.
Heworth's east York position means standard Vale of York rainfall, with east-facing elevations potentially more exposed to cold north-easterly weather that can accelerate render weathering.

Our approach
Free on-site survey
We visit the property, assess the substrate — masonry, existing render, pebbledash — and establish what preparation is needed. We take measurements, advise on colour options from the manufacturer range, and identify any structural issues (cracking, blown sections, damp) that need addressing before rendering.
Preparation
Sound preparation is what determines how long the finished system lasts. We clean the substrate, repair cracked or blown areas, apply primer where required, and fit render beads and trims to all external angles, window and door reveals, and the render termination line at the base of the wall. Scaffolding is erected where required.
Base coat
A polymer-modified base coat is applied and reinforced with fibre mesh embedded into the wet render. This base coat forms the structural layer of the system, distributing any minor movement across the wall and preventing point-stress cracks reaching the surface coat.
Silicone finish coat
The silicone finish coat is applied to the cured base coat. It is textured to the specified profile — fine, medium or coarse — and coloured throughout. The surface is self-cleaning and breathable from day one.
Inspection and handover
We inspect the completed elevation with the client, address any snagging, remove scaffolding and clear waste before leaving. System warranty documentation is provided on qualifying installations.
What determines the cost
We provide fixed written quotes — what you are quoted is what you pay. The factors below determine where your project sits within the range for this type of work.
- Total wall area — measured in square metres
- Substrate condition — significant preparation (removing failed render, repairing masonry) adds cost
- Scaffolding requirement — multi-storey or larger properties require more scaffolding
- Access constraints — terraced properties, tight plots or limited road access
- Extent of existing roughcast or render blow — more cut-out and repair work before the new system can go on
The most accurate way to understand the cost for your specific property is a free on-site survey. We assess the substrate, take measurements and provide a full itemised written quote.

Common questions
Will silicone render work on a solid brick wall?
Yes — silicone render is specified for solid masonry as well as cavity walls. On solid-walled properties, the breathability of the render system is important: silicone render allows water vapour to pass out through the wall, which is correct for solid construction. The substrate preparation and primer selection need to be matched to the masonry type. We assess this during the survey.
Can silicone render be applied over existing render?
Only if the existing render is fully sound, well adhered and structurally stable. Any sections that are hollow, cracked through or blown must be cut out and repaired before a new system is applied over the top. Applying a new render system over a failing substrate is one of the most common causes of early failure. We assess the existing render during the survey — if it is not in a good enough condition, we will tell you.
Does silicone render need painting?
No — and it should not be painted. Silicone render is through-coloured and its self-cleaning behaviour depends on the silicone surface remaining exposed. Painting over it traps moisture and negates the water-repellent properties. If the colour has faded significantly, a silicone-based exterior coating by a specialist is the correct approach rather than paint.
Is silicone render suitable for an exposed Pennine-facing property?
Yes — provided the system is correctly specified for the exposure level. For properties in high wind and rain exposure zones, the key factors are substrate preparation quality, full base-coat coverage with mesh reinforcement, and the correct termination details at the base of the wall, around windows, and at the eaves. We assess exposure during the survey and confirm the system is rated for the conditions before recommending it.
