How Cladding Cleaning Works
Cladding cleaning must be done using the appropriate method for each material. Surface finishes vary widely across warehouse metal cladding, office aluminium panels, retail UPVC frontages, and residential composite. If the pressure or cleaning solution is wrong, cleaning will cause irreversible damage.
Our standard strategy: we start by applying a controlled solution of sodium hypochlorite to the entire facade, then allow dwelling time to break down organic growth and surface contamination. To remove residues and improve appearance right away, we finish with a light rinse of the surface. For robust materials (unpainted metal, corrugated sheets, fibre cement), we use controlled pressure. We use low-pressure soft washing on delicate panels like painted metal, UPVC, timber, or composite. For large commercial facades and elevations up to 12 metres, we use extendable telescopic poles from ground level.
We follow cleaning with applying a DDAC biocide treatment across the entire surface. This will prevent the regrowth of algae, moss, and bacteria as it adheres to the panels and activates every time it rains. This step provides protection for 4-5 years. When biocide isn't used, algae will regrow within 6-12 months on north-facing elevations.
Commercial cladding cleaning prices start from £400. Residential from £300. Call 07307 358765 for a free estimate.
