Render Cleaning in Farnham
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
If you are weighing up render cleaning in Farnham, the starting point is what your walls are actually built from.
Across Surrey, tile-hung and timber-framed cottages, Victorian villas and substantial modern housing dominates, and high-specification smooth render and appearance-led refurbishment is what we are called out to most often.
Local conditions bring a moderate southern climate, and that has a direct bearing on which systems are worth specifying. Work here skews heavily toward discretionary upgrade rather than failure repair, so finish quality and colour matching carry unusual weight.
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 Farnham
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.
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.
