Commercial render inevitably accumulates staining and organic growth. Left untreated, algae, mould, traffic film, and air-borne pollutants cause streaking, patchiness, and premature degradation. Servos Exterior Cleaning provides a specialist commercial render cleaning service that restores façades safely and keeps them cleaner for longer, without the risks of high-pressure washing.
Our method centres on professional softwashing for render backed by targeted treatments and low-pressure rinsing. We clean K-Rend, Weber, Sto-Rend, Parex/monocouche, silicone and acrylic renders, insulated render systems (EWI), and more, delicately, thoroughly, and with minimal disruption to your site.
What Is Commercial Render Cleaning?
Commercial render cleaning is a controlled, low-pressure process that removes algae (green, red, and black), mildew, lichen, carbon staining and general grime from rendered façades. Unlike traditional jet washing, softwashing render uses carefully dosed, render-safe solutions and controlled rinses to break down contamination at the root, protecting finishes, sealants, and pointing.
For stubborn pollution film or localised staining, we complement softwashing with precision rinsing and, where appropriate, gentle steam detailing, always at settings suitable for delicate substrates.
Signs Your Commercial Roof Needs Cleaning
Over time, pollution, moisture, and organic growth can cause visible staining and discolouration on rendered surfaces, affecting both the appearance and longevity of your building.
- Green, red, or black algae streaks on elevations, often worse on north-facing or shaded walls
- Brown/grey traffic film and “tide marks” beneath window sills, parapets, or copings
- Moss build-up around gutters, downpipes, plant rooms, or plinths
- Patchy, dull, or chalky areas where colour has become uneven
- Persistent drip lines from HVAC overflows, fixings, or architectural details
If you’re seeing any of the above, your facade will benefit from a professional commercial render cleaning treatment to restore appearance and slow future regrowth.
Why Choose Softwashing for Render?
Softwashing is the industry-preferred method for render cleaning because it is gentle, effective, and long-lasting.
- Safe for modern renders – Low pressure protects silicone/acrylic finishes, monocouche, and EWI systems.
- Removes contamination at source – Formulations neutralise biofilms and spores to delay regrowth.
Colour-true results – Lifts staining without scouring or burn marks associated with high pressure. - Low water usage & fast drying – Minimises water ingress risks and speeds return to service.
- Smart for busy sites – Quiet operation and flexible scheduling reduce operational disruption.

The Benefits of a Professional Render Cleaning Programme
1 . Protects the Substrate
Our render cleaning service uses measured chemistry and low pressure to avoid surface erosion, hairline damage, or water tracking behind coatings.
2. Longer-Lasting Clean
By tackling spores and biofilm, softwashing extends the interval between cleans, supporting lower life-cycle costs for façade maintenance.
3. Compliance & Kerb Appeal
Cleaner elevations support brand reputation, tenant satisfaction, and health & safety standards across multi-site estates.
4. Rapid Drying & Minimal Disruption
Efficient rinsing and low water volumes mean quicker drying times, fewer access constraints, and predictable programmes.
5. Environmentally Responsible
We use biodegradable, render-appropriate solutions, controlled dosing, and capture/containment where required, aligned to COSHH and environmental best practice.
Our Commercial Render Cleaning Process
- Initial Survey & Test Area – We identify render type (e.g., silicone, monocouche), map contamination, inspect sealants and detailing, and carry out a discreet test patch to confirm the specification.
- Access & Protection – We plan safe access (MEWPs/rope access/scaffolds), protect glazing and landscaping, and coordinate with facilities teams for safe cordons and signage.
- Targeted Softwash Application – Metered, render-safe softwash chemistry is applied to break down biofilms and staining without damaging the finish.
- Controlled Low-Pressure Rinse – We rinse at low pressure to lift contamination and residues while protecting the substrate, edges, and sealants.
- Detailing & Stain Treatments – Localised treatments for drip lines, bird fouling, or rust/efflorescence; gentle steam detailing may be used where appropriate.
- Post-Treatment & Aftercare – A biocidal post-treatment (render-compatible) can be applied to inhibit regrowth. We provide an aftercare plan with recommended re-inspection intervals.
