Stone Cleanomg

A data sheet on our stone cleaning services, a suitable summary for printing is available in pdf format, here

We specialise in using a low pressure sand jetting system that has been used nationwide for property restoration, including gaining approval for and subsequently working on many Listed Buildings.

The system, in our trained hands, causes minimal damage to an underlying surface and is flexible enough to tackle most property restoration cleaning tasks.

The low pressure sand jet can clean stone without injecting large quantities of water into the surface, and with minimal surface damage, at the same time, the 'wet' system also captures dirt and abrasive, preventing the health and safety risks associated with dry blasting.

A Partially Cleaned House in Sheffield - cleaned by us in December 2003 Note also that the building has not been scaffolded - a significant saving compared to traditional dry blast systems that need scaffolding and sheeting to contain the blast media. Note that the windows have been boarded over with plastic sheet to protect them.

A further advantage of the system we use is that it also uses far less abrasive than traditional techniques, making expensive abrasives cost effective, but more significantly reducing waste. Abrasive does not need to be recycled, preventing cross contamination between jobs, and apart from in specialist cases, is not a major part of the running costs.

The sand jet will only blow out loose pointing. In general re-pointing is unnecessary after using this process. Paint can be just as effectively removed from stone, as from brick.

 

The Assembly Rooms in York. A very Listed building, Cleaned by us for Lanstone Conservation (who undertook stone repairs at the same time) 2008. With the size and location a fully sheeted and boarded scaffold was required for this job.

Cleaned (and stone repairs done) a few weeks later.

Hull's Boer War Memorial - Cleaned in October 2001

Key Benefits

• The low pressures mean that the system is gentle enough to clean delicate surfaces, yet powerful enough to strip multiple layers of paint in one pass.
• It is not a chemical process so no noxious or harmful slurries or fumes are generated.
• As it uses only minimal amounts of water and abrasive the system is regularly used indoors.
• Considerably less mess than other systems.
• Cleaning to the requirements of BS 8221-1&2 :2000 the British Standard Code of Practice for Cleaning and Surface repair of buildings.
• Quick efficient Graffiti Removal. No interference with other work in area.
