Render Cleaning in Johnstone
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
Our render cleaning work in Johnstone starts with a free survey, because guessing at a render specification is how jobs go wrong.
The prevailing picture in Renfrewshire is sandstone tenements, Victorian terraces and postwar estates. That means tenement harling and render failure on sandstone terraces comes up more here than almost anywhere else.
The area sees wet with strong exposure along the Clyde, which is the single biggest factor in how long any render lasts here. Clyde-side exposure and high rainfall mean west-facing tenement elevations here weather considerably faster than sheltered ones.
When render cleaning is the right call. Choose soft-wash cleaning to restore a discoloured render without the substrate damage that pressure washing causes on thin-coat systems.

FAQs
Render Cleaning in Johnstone
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.
