Thomann-Hanry® are all about improvement in façade renovation.
As first impressions count, the exterior of your building influences a visitor’s opinion, even before they set foot inside.
Thomann-Hanry® have forged a reputation for remarkable non-scaffold transformations of historic buildings using façade gommage®, as well as stone restoration, internal floor restoration, metal cleaning and painting. From the Bank of England and the Ritz to the Reform Club and King’s College, Cambridge, our highly specialised processes have gently lifted and removed generations of grime to reveal these landmarks in all their original splendour.
Our patented system façade gommage® is a facade cleaning technique that projects fine, sharp powders under compressed air to gently loosen, lift and remove layers of dirt, leaving the underlying stonework undamaged and in its bright, original state.
Façade gommage® is slowly but surely transforming and revitalising the streetscene in London. Better still, as the process is carried out from a lorry-mounted cabin, the day to day lives of building occupants, visitors and passers are unaffected. The buildings themselves are kept free of unsightly scaffolding from start to finish.
Working meticulously on each building, our Survey teams can identify areas in need of restoration, repair or redecoration, including windows and timber. Where sections of masonry are beyond repair, our banker masons source and work with matching materials to faithfully recreate replacement stones to slot invisibly into the existing structures.
As our uniquely gentle process is ideally suited to Listed buildings, we’re proud to have worked closely with Historic England and conservation teams on many iconic buildings – not only in London but across the UK – erasing decades of dirt and revealing the breathtaking beauty of this country’s proud architectural heritage.
Through our projects, you find out more about this fascinating process and its transformational effects.
