About Us

About Us

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

The Company has grown considerably since then and ‘façade gommage’® has been used to restore many of the world's most high profile, iconic buildings. Click here to see our Case Studies. In addition to Paris, we now have offices in Amsterdam, Brussels, Geneva, Lisbon, Luxembourg, Madrid, Milan, New York, Montreal and of course, London.

To ensure consistent quality control, the materials and equipment we use and the all important on-site application process are the same all over the world. This assures our clients that every project using the ‘façade gommage’® system will achieve the same impeccable standards.
