Gwynedd
Rendering in Porthmadog
Render, repair, pebbledash removal and external wall insulation for Porthmadog homes — with a free survey before any price is quoted.
Gwynedd is characterised by slate and stone cottages, quarry housing and exposed coastal properties, with extreme driving rain on slate and stone construction the recurring theme on the properties we survey.
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.
How we approach a job in Porthmadog
Every Porthmadog enquiry starts the same way: we come out, tap-test the existing coat, check the substrate behind it and look for the reason anything has failed. Blown render is nearly always a symptom — of a leaking gutter, a bridged damp course, a cracked sill or an over-strong mix — and re-rendering over an unresolved cause simply buys a couple of years.
Every quote follows a free survey — no estimates over the phone, because we cannot see your walls from here.

FAQs
Rendering in Porthmadog — common questions
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.
How long before I can paint new render?
Through-coloured systems need no painting at all. Sand and cement should cure for around 28 days before masonry paint goes anywhere near it.
Do you take a deposit?
For most domestic jobs we take a deposit to cover materials and scaffold, with the balance on completion. Terms are set out clearly in the written quote.
Can you match my existing render?
Usually, yes. We colour and texture match as closely as we can, though weathered render never matches a fresh batch exactly — we will be honest about how visible a patch will be.
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.
