Cladding cleaning for commercial businesses removes dirt, algae, and pollution from building exteriors, helping to restore a clean, professional appearance. When left untreated, this build-up can trap moisture and lead to issues such as staining, surface deterioration, or long-term damage to cladding materials.
At Neptune Cleaning, we provide safe, non-abrasive cladding cleaning services for businesses and commercial sites. Whether you manage offices, retail units, schools, healthcare facilities, or industrial buildings, we tailor our approach to suit your cladding type and building layout, helping to maintain both appearance and long-term condition.
We tailor our commercial cladding cleaning service around how your building is used and operated. For high-traffic retail and public-facing sites, we prioritise uniform panel cleaning to remove visible streaking, traffic film, and lower-level staining that affects first impressions.
For offices, schools, and healthcare environments, we plan access and cleaning schedules carefully to avoid disruption, selecting cladding-safe methods that prevent water ingress around windows, joints, and service penetrations. Whether the requirement is a one-off refresh or a structured maintenance programme, our approach is adapted to the building’s function, occupancy, and cladding layout.
Our commercial cladding cleaning service is designed not only to improve appearance, but to protect cladding systems over time. After cleaning, we apply a specialist biocide treatment directly to cladding panels, joints, and overlap points where organic growth commonly returns, helping to prevent the rapid re-growth of algae and staining.
By treating the cladding as a complete system rather than just the visible surface, we slow the build-up of traffic film and biological growth across large elevations. This keeps cladding cleaner for longer between cleans and reduces the need for frequent maintenance visits, helping businesses maintain a consistent, professional exterior.
This image shows a specialist cleaning system installed within one of our service vehicles, purpose-built for commercial and industrial cladding cleaning. The equipment is designed to clean cladding panels safely and evenly, using controlled water pressure and flow to suit materials such as aluminium, steel, composite panels, and powder-coated finishes without stripping coatings or forcing water behind panels or joints.
The system includes long-reach hose reels that allow our team to clean continuous runs of cladding across large façades and elevations without interruption. Combined with cladding-specific brushes and low-impact washing methods, the setup enables the effective removal of traffic film, algae, and atmospheric pollution that commonly builds up on cladding systems. All equipment is securely mounted to ensure safe, consistent operation, allowing us to clean commercial cladding efficiently while protecting panel finishes, fixings, and seals.
