Render makes a property look modern, clean, and professional. But when algae, moss, and pollutants take hold, render quickly turns green, patchy, and stained. What once looked sharp and fresh soon looks tired and neglected.
Render cleaning is not just about appearance. Left untreated, algae growth damages the surface, traps moisture, and shortens the life of the render. Replacing render is one of the most expensive forms of property repair, and unnecessary when cleaning is carried out properly.
This guide explains why render cleaning matters, the common problems property owners face, the methods that work, and how professional services protect your investment for years to come.
Why render gets dirty
UK weather creates the perfect conditions for algae and moss. Damp autumn months combined with low sunlight allow green staining to spread quickly across north-facing walls. Urban areas add another layer of pollution and carbon staining, leaving render looking older than it really is.
The risks of leaving render untreated
Green and black algae staining that spreads across walls
Moisture retention leading to cracking and structural damage
Render decay that requires costly replacement
A negative first impression on customers or tenants
Ignoring render maintenance leads to long-term expense and a tired-looking property.
DIY cleaning vs professional render cleaning
Homeowners and property managers often try to pressure wash render. This is a costly mistake. High pressure blasts the surface, causing cracks and etching that weaken the render permanently.
Professional cleaning uses soft washing and steam cleaning methods. These techniques kill algae at the root, gently remove stains, and leave the render intact. The result is a clean, bright finish without damage.
The render cleaning methods that work
Soft washing: a low-pressure system with specialist biocides that kill algae spores and prevent regrowth
Steam cleaning: gentle heat that lifts stains without damaging the surface
Targeted chemical treatments: for heavy black staining or carbon deposits on urban properties
Preventive treatments: biocidal washes applied after cleaning to slow future growth
How often should render be cleaned
For most properties, render should be cleaned every 2 to 3 years. Properties in shaded or damp locations may require more frequent cleaning to prevent green algae from spreading.
What it costs
Professional render cleaning in the UK typically ranges from £500 to £2,000, depending on the size of the property and severity of staining. Compared to the cost of full render replacement, which can run into tens of thousands, professional cleaning is a smart investment.
Commercial render cleaning
For schools, office blocks, retail units, and apartment complexes, render is the face of the building. Dirty render sends the wrong message to staff, customers, and tenants. Regular professional cleaning keeps the building looking sharp, reduces long-term maintenance, and protects property value.
