Porthmadog, Gwynedd
Silicone Render in Porthmadog
Breathable, self-cleaning silicone thin-coat render in a through-colour finish that never needs painting.
Porthmadog property owners come to us for silicone render for one of two reasons: something has failed, or the house looks tired.
Across Gwynedd, slate and stone cottages, quarry housing and exposed coastal properties dominates, and extreme driving rain on slate and stone construction is what we are called out to most often.
Local conditions bring among the highest rainfall in the UK with severe exposure, and that has a direct bearing on which systems are worth specifying. Snowdonia records some of the highest rainfall in britain, and any non-breathable render on stone here will trap water within a single winter.
When silicone render is the right call. Choose silicone where you want a low-maintenance, breathable finish on a solid-wall or insulated property and you don't want to repaint every five to seven years.

FAQs
Silicone Render in Porthmadog
Does silicone render need painting?
No. The pigment is mixed through the topcoat. Painting it would actually reduce the breathability and self-cleaning behaviour you paid for.
Is silicone render breathable?
Yes, highly. It has a low water-vapour resistance, which is what makes it suitable for solid-wall, stone and lime-built properties where trapped moisture is the main risk.
How long does a rendering job take?
A typical three-bedroom semi is usually one to two weeks on site including scaffold, preparation, application and finishing. Weather, wall condition and the system chosen all move that.
Do I need planning permission to render my house?
Usually not on a standard house, but you will if the property is listed, in a conservation area, or if rendering would significantly change its appearance. We flag it at survey.
Will you need scaffolding?
For anything above single storey, yes — it is safer and produces a better finish than working off ladders or towers. Scaffold is included and itemised in the quote.
