Exterior Cleaning

What is Exterior Cleaning?

Exterior Cleaning is essential for maintaining the appearance and condition of your building. Instead of high-pressure water blasting, we use a low-pressure enviro-clean method combined with eco-friendly chemicals. This approach gently lifts dirt, algae and contaminants without damaging cladding, paint, windows or surrounding surfaces. It’s a safer, more effective alternative to chlorine-based sprays and avoids long-term corrosion or deterioration of materials and finishes. As part of this service, we also clean exterior windows, leaving glass clear and streak-free.

Is Exterior Cleaning right for you?

Common applications in commercial and industrial settings include:

• Food manufacturing sites and cool stores
• Office buildings, warehouses and retail properties
• Sites affected by moss or algae growth on walls, paths or cladding
• Roofs that have become slippery or unsightly
• Buildings with insect nests, cobwebs or bird activity
• Facilities preparing for audits, inspections or refurbishments

What are the benefits of Exterior Cleaning?

• Removes algae, moss, dust, cobwebs and bird mess without damaging surfaces
• Reduces slip hazards and improves the hygiene and safety of your site
• Enhances the appearance of your property and maintains a professional image
• Avoids the risks of high-pressure water blasting or corrosive chemicals, making it safe for delicate surfaces and exposed materials
• Can be completed safely at height, with our trained EWP-certified technicians and hazard controls for full HSE compliance
