Cleaning building facades efficiently, swiftly and to the highest standards

Thomann-Hanry® was established in 1946 by Robert Thomann, in Paris. Over the years, Mr Thomann refined and perfected the façade gommage® masonry cleaning system, developing the unique, low-pressure, dry and scaffold-free façade cleaning process we use today.

Thomann-Hanry®’s façade gommage® is the only system specifically designed to professionally clean exterior building facades without the need for scaffolding – enabling businesses to function normally while works are in progress.

Holding accredited environmentally friendly credentials, as it does not require gallons of water or any chemicals, the system was patented in 1985. Today, the façade gommage® cleaning technique is in high demand to restore many of the world’s most iconic buildings.

Established in the UK since 2005, Thomann-Hanry® have grown as an award-winning main contractor for external facade restoration. Using its secure and efficient non-scaffold façade cleaning system, the company has cleaned and renovated hundreds of London’s most historic building facades.

“Thomann-Hanry® are at the forefront of the exterior stone cleaning and restoration industry – and have been for a number of years. Cleaning and maintenance work is vital to ensure the preservation of iconic buildings in the city”
