Render Cleaning in Holywood
Soft-wash render cleaning and biocide treatment that removes algae without damaging the finish.
Holywood 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. The ards peninsula is exposed on both sides, so properties there weather from multiple aspects rather than one prevailing direction.
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 Holywood
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.
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.
