Industry blast cleaning experts working throughout the UK

We are considered industry experts and have completed preservation projects on some of the country’s most complex historic buildings, including St Fagan’s National History Museum, where we removed centuries worth of tar and smoke residues from the inside a 30-foot chimney.  This demanded very careful work as the acidic conditions rendered the interior surfaces of the chimney extremely delicate.

Health and safety are paramount to us. Full documentation, including method statements, risk and COSHH assessments, Health and Safety Policy and Environmental Policy will be provided for every cleaning and restoration task.

Heritage Property Restoration

Blasting soda is an extremely soft media with about the same hardness as talcum powder (2.4 on Moh’s hardness scale) and will therefore not cause damage to the substrate of surfaces. It is used in historic and heritage property restoration to clean and remove surface deposits from:

  • Building facades
  • Stone including sandstone, limestone, York stone, Portland stone, marble cleaning, terrazzo and granite
  • Flagstone flooring & path ways
  • Fountains and ornamental sculptures
  • Ceramics and glazed tiles
  • Glass & stained glass
  • Structures and monuments manufactured in ferrous & non ferrous metals including anodised aluminium, stainless steel, brass, copper, bronze, cast and wrought iron
  • Plastics & nylon components
  • Rubber & neoprene
  • GRP, fibre glass & plastic coatings


Blast Cleaning Services for Conservation of Historic Buildings

Blast Cleaning is a broad term to describe a few different processes used in the restoration and preparation of surfaces. It can involve both dry blasting and wet blasting using different grades of blast cleaning media. Contact us for advice about the best method of application and the correct blast media to ensure optimum results and the desired finish.

Fire and Flood Restoration

The soda blasting process saves both time and money by salvaging and deodorizing assets once deemed as total losses. It quickly neutralises smells from mould and algae after flooding as well as toxic pollutant residues left behind from fire damage.  Fire and Flood Restoration
