What affects the cost of commercial render cleaning?
- Render type — K-Rend, Monocouche, silicone, spar-dash, and pebble-dash each need different biocide and technique combinations.
- Facade area (m²) — most contracts price per square metre of render surface.
- Building height — single-storey elevations clean from ground with extendable poles; anything above 10m needs MEWP or rope access.
- Soiling level — heavy algae, moss or lichen may need a two-stage biocide + second visit after the kill-off period.
- Site access — city-centre sites with pedestrian areas, permit requirements, or hoarding can add cost.
- Protection requirements — neighbouring glass, cladding, or landscaping may need masking/protection.

Frequently asked questions
How much does commercial render cleaning cost per m² in the UK?
For accessible single and 2-storey render, £6–£12 per m². Multi-storey work needing MEWP or rope access runs £15–£30 per m².
Is render cleaning safe for K-Rend and Monocouche?
Yes — we use low-pressure soft-wash with biodegradable biocide specifically formulated for these render types. No high-pressure, no surface damage, no colour bleaching.
How long does the clean last?
A proper soft-wash biocide treatment typically keeps algae and black staining at bay for 2–4 years depending on location, aspect, and local tree cover. Sites near woodland may need more frequent cleans.
Do you offer scheduled maintenance contracts?
Yes. Annual or bi-annual render-maintenance contracts keep facades consistently clean and typically cost 20–30% less per visit than one-off treatments.
Can I get a fixed price before the work starts?
Yes — every commercial quote is a fixed price. We survey the site, agree the scope in writing, and the quoted price is what you pay.
Do you clean heritage and listed buildings?
Yes — we use conservation-grade soft-wash techniques and liaise with listed-building officers where required. Always quoted individually.
Will the biocide damage plants or landscaping?
No — we use biodegradable biocide that is safe around plants, lawns, and pets when diluted to working concentration. We also protect sensitive planting with sheeting during application.
Are you insured?
Yes — £10 million public liability, employer’s liability, and professional indemnity. RAMS provided for every commercial site before work begins.
