Rendering

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 properties in Conisbrough rely on external render for weather protection — silicone render is chosen for re-renders in the area for long-term durability.

Why customers call us

Common situations we resolve

Conservation area properties seeking a silicone render that is an acceptable alternative to the existing mineral finish — colour and texture selection matters

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

Conisbrough

Property considerations in Conisbrough

Conisbrough is a town south of Doncaster known for Conisbrough Castle, a well-preserved Norman keep. The housing stock includes Victorian brick terraces and semi-detached properties in the older parts of the town, interwar development, and post-war estates. The town sits in the Don valley below Conisbrough Cliffs. Many older properties have solid masonry walls. The castle and surrounding area are popular visitor destinations.

Conisbrough's Don valley position south of Doncaster means standard South Yorkshire rainfall — the valley floor is relatively sheltered from westerly weather, though exposed hillside properties face more demanding conditions.

Properties near Conisbrough Castle and within the historic town area may be subject to conservation area planning conditions on external appearance.

How we work

Our approach

01

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.

02

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.

03

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.

04

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.

05

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.

Pricing

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.

FAQs

Common questions

Is silicone render acceptable in a conservation area?

It depends on the local authority's approach and the specific property. Many conservation areas prefer mineral or monocouche finishes that read as more traditional than polymer silicone. Some councils accept silicone render in subdued colours on non-primary elevations. We advise on what has been accepted for similar properties locally, but confirmation with the local planning authority before work begins is always recommended.

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.

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.

Do I need planning permission for render work in Conisbrough?

For most residential properties in Conisbrough, changing external render colour or applying a new render system does not require planning permission. However, properties within Conisbrough's conservation areas, or that are listed buildings, may need consent before any change to external appearance. We flag this risk during the survey and can advise on what is likely to be acceptable — but confirming with the local planning authority is recommended before work proceeds.
