Render Cleaning in Knighton
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
Render Cleaning in Knighton is work we take on regularly, and the Powys housing stock is a big part of why.
Powys is characterised by stone farmhouses, timber framing and rural cottages, with lime render on rural stone and timber-frame properties the recurring theme on the properties we survey.
The area sees high rainfall with exposed upland conditions, which is the single biggest factor in how long any render lasts here. Powys is overwhelmingly rural, solid-wall and upland, which makes breathable lime the standard specification rather than a heritage exception.
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 Knighton
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 render cleaning last?
Typically two to four years before noticeable regrowth, depending on shading, aspect and nearby vegetation. Annual maintenance treatments extend that considerably.
Why is only one wall green?
North-facing and shaded elevations stay damp far longer, so algae establishes there first. Overhanging trees and leaking gutters accelerate it.
