Keystone Preservation Ltd

Keystone Preservation provides specialist industry accredited cleaning solutions for building restoration and conservation. Our bespoke, technology-lead approach creates a cleaning solution specific to each and every building we visit.

Our Service
Our fully trained staff carry out site surveys using drone technology to provide an unobtrusive video inspection of the building prior to the commencement of any work. Our engineers use tracked access lifts enabling them to access any hard to reach areas both inside and outside of the building without the need for costly and intrusive scaffolding.

Historic
Protecting the surface of your building is key when cleaning a historic building. Whilst the temperature in the system is high, the pressure on the surface being cleaned is very gentle and the volume of water is low resulting in unsaturated stonework that will be dry within minutes. The aim is to clean and remove dirt, staining and biological build up without damaging the surface or altering the patina of the stonework.

• Biological Matter
  The build up of biological matter over several years will result in staining to a buildings surface. Keystone are able to remove moss, algae, fungi and other biological matter using only steam.


• Surface Pollutants
  Years of continual build-up can cause lasting staining which cannot be removed by high pressured water. Using steam with temperatures that reach 150 degrees Celsius, Keystone Preservation have an overwhelming success rate in removing pollutants from a building surface whilst causing zero damage to the stonework.

Equipment

• DOFF
  DOFF is a steam based surface cleaning system. It is unlike any other steam system and can achieve temperatures of up to 150 degrees at the nozzle end – making it a ‘super-heated water/ steam system’. The DOFF systems will remove moss, algae, fungi and other biological matter form most surfaces including stonework, masonry and paving. The steam not only removes the build up of matter but also kills off spores meaning there is then no need to use a chemical biocide during the removal process or as a protection against further biological activity.



• Spiderlift
  The Spiderlift is a narrow tracked boom lift designed to access areas that traditional cherrypickers can’t and is often used in place of traditional and expensive scaffolding systems. Our spiderlifts feature dimensions compact enough to fit through standard single of double doorways increasing its versatility. With working heights of up to 19 metres and power options including diesel, mains and battery options the spiderlift is perfect for a range of internal and external property maintenance.
