Render Cleaning in Down
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
Down property owners come to us for render cleaning for one of two reasons: something has failed, or the house looks tired.
Across Down, stone and brick cottages, coastal villas and modern housing dominates, and coastal salt and driving rain on exposed peninsula properties is what we are called out to most often. The area sees wet with strong coastal exposure on the Ards peninsula, which is the single biggest factor in how long any render lasts here.
Local factor. The ards peninsula is exposed on both sides, so properties there weather from multiple aspects rather than one prevailing direction.
Is render cleaning right for a Down property?
Choose soft-wash cleaning to restore a discoloured render without the substrate damage that pressure washing causes on thin-coat systems.
That decision gets made at the survey, not on the phone. We will tell you plainly if a different system would serve the building better — including when a cheaper one would.

FAQs
Render Cleaning in Down — questions
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.
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.
