Whilst no job is too small, our Gommage® cleaning system really comes into its own when used on large buildings with a surface area of 500 sq m or more.

Our biggest project to date is the Louvre in Paris, which is a staggering 136,000 sq m. The highest challenge was the 56-storey MetLife skyscraper on New York’s Park Avenue.

Most masonry and stone cleaning companies use copious amounts of water. The Thomann-Hanry® system is different. We pride ourselves on our environmentally friendly credentials, as we don’t use gallons of water or any chemicals. Our cleaning powders are mainly organic or mineral in composition and are either biodegradable or recycled, so not only will you be helping to save the planet, but you won’t be affected by any water restrictions in your area. The only water used is to dampen down the dust collected by the Gommage® system, which is then filtered and recycled.

We’d like to add to our ever-growing global portfolio with projects here in the UK. We are also interested in working with established restoration companies. Please get in touch for more information.
