Keystone are specialists in cleaning and restoring commercial building exteriors. Your building exterior is the first thing clients, suppliers and customers see as they arrive at your facility and at Keystone we understand the importance of good first impressions.

Our Service

Exterior cleaning can be a difficult task due to height and access. We have a wide range of equipment to tackle such jobs including our high reach spider lifts which enable us to work at heights of up to 19 meters, eliminating the requirement for costly and intrusive scaffolding.

Biological matter can build up on most exterior surfaces, from walkways to step and paths. When wet, the surface can become extremely slippery and hazardous for customers and staff. Our specialist systems are able to remove this build-up from multiple surfaces reducing your risk as the employer.

Keystone’s commercial services include, but are not limited to:

  • Cladding cleaning (removes / carbon/petroleum based contaminants/ moss/ algae/ general dirt/ lime scale and effervescence staining/ microorganisms/ air pollutants)
