Render Cleaning in St Ives
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
St Ives property owners come to us for render cleaning for one of two reasons: something has failed, or the house looks tired.
Most of what we see around St Ives reflects the wider Cornwall pattern — granite and cob cottages, slate-hung walls and exposed coastal housing, and driving-rain penetration and salt damage on exposed elevations.
The area sees severe driving rain and salt-laden coastal exposure, which is the single biggest factor in how long any render lasts here. Exposure here is category-defining — dashed and roughcast finishes genuinely outperform smooth render on west-facing coastal walls.
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 St Ives
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.
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.
