Restoring Excellence The world leading faรงade cleaning experts
“Despite the presence of exceptionally high levels of pollution which had accumulated on the limestone façade over many years, Thomann-Hanry® was able to clean the entire sevenstorey building in just two days. They organised all the permits and managed the site so that the work could be undertaken on one of London’s busiest streets without disrupting traffic, pedestrians, retailers or office workers. Their operation was excellent and, best of all, the building’s appearance was transformed.” Marc Cross, Associate Director, Building Consultancy – Hartnell Taylor Cook
Cleaning building façades 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 cleaning process that we use today. Thomann-Hanry®’s façade gommage® is the only system specifically designed to professionally clean exterior building façades without the need for scaffolding – enabling businesses to function normally while works are in progress.
Using its secure and efficient non-scaffold façade cleaning system, the company has cleaned and renovated hundreds of London’s most historic building façades.
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.
Committed to providing the highest levels of service, Thomann-Hanry® has also developed Aqua Fend®, a range of products to protect both façades and ground surfaces against moss, graffiti, water, dirt and pollution.

A revolution in building faรงade cleaning and restoration
First impressions count The exterior of your building influences a visitor’s opinion, even before they set foot inside. The patent-protected Thomann-Hanry®’s façade cleaning system is the solution you need to optimise the curb appeal of your business. Our unique non-scaffold process yields impressive results with minimal disruption. When considering a building exterior clean, using a unique system that does not require the use of scaffolding can make the work significantly easier. Business can continue to run as usual, minimising loss of trade, maximising profit potential and maintaining 'as normal' day-to-day operations, whatever the business. Façade gommage®, more than any other cleaning techniques, provides unrivalled results with detailed stonework such as dentils, cornices, modillions, and statues. The powder is so fine it can clean the smallest of crevices with none of the risks associated with pressurised or superheated water. Unlike other traditional techniques, which can have a harmful high impact, the façade gommage® system provides perfect results without damage.

The facelift experts The future of façade restoration Sympathetic and knowledgeable restoration of building façades is a specialised skillset encompassing several highly prized trades – from hand-carving stone and the replacement of sections worn away through years of exposure to the elements, to installation of new timber around long decayed window frames. Metal, brick or stone – whatever the material, time and weather will eventually wear it away.
Scaffold-free restoration Contrary to popular misconception, virtually all types of restoration work can be undertaken from platforms – a huge advantage for occupied buildings with regard to speed, security and efficiency. Using platforms instead of scaffolding, we have carried out stone repairs, repointing, roofing, painting, mastic replacement and bird proofing on many high profile buildings across London and further afield.
Professional façade cleaning, masonry repairs and external building refurbishment Thomann-Hanry® is unique in its approach to restoration in several ways. First and foremost, our artisans are in-house, continually trained and operating with top of the range tools and equipment. Our Restoration team complements other divisions of the company by offering the full breadth of building restoration from Thomann-Hanry® mobile platforms, thus removing the need for scaffolding from almost any project. There is no element of work on the façade of a building that the Thomann-Hanry® Restoration team cannot carry out.
• Our banker masons produce the replacement stones that our restorers introduce to buildings. • Our carpenters create the new sections of timber that we use to replace where window frames have passed the point of repair. • Our decorators bring timber and metalwork, long-faded by the elements, back to life. • Our lead workers carry out a full range of services to any structure, including lead repairs and replacement, extensions, modifications and sympathetic, partial restoration of Listed buildings to heritage standards. • Bird deterrent systems are introduced, stone or brick restored and protected, stains and marks removed.
Structural and building surveys in detail We are often approached for advice and recommendations in regards to building defects and preventative maintenance, and to that end employ a façade specialist qualified to CEng MICE MIStructE MSAICE, as well as a MEng qualified Senior Mechanical Engineer. Whilst façade surveys are our specialty; we also bring our expert knowledge of structural engineering and historic materials to bear on defects relating to the whole structure, assessing the extent and cause of any damage before providing an analysis of the most viable solutions. We perform visual surveys from MEWP wherever possible and, if necessary, with the assistance of our Restoration teams, carry out
more invasive investigations of properties to determine the most appropriate methods for repairs, alterations or other modifications as specified by the client. At Thomann-Hanry®, we can laser scan façades to produce precisely accurate elevation drawings prior to the survey and carry out testing to the client’s property and its materials. If we are the appointed contractor, our Engineers are an integral part of our team – if not, they can act independently. In either case, they provide a vital resource to ensure works are completed to the best possible methodology and specification.
When considering works to a Listed building, Listed Building Consent (which is separate from Planning Permission and Building Regulations Approval) is usually required. Here at Thomann-Hanry® we directly employ highly qualified consultants capable of submitting applications and supervising works, as well as dealing with any queries which arise along the way. Over the last ten years, we have worked on hundreds of Listed buildings from Grade I up to Scheduled Ancient Monuments. Our façade gommage® system was recently evaluated by conservationists using laser scanning, prior to approval by Historic England, and was shown to be no more disruptive than water cleaning. Using no water or chemicals, we remove the pollutants without adversely affecting the patina, preserving the character of the stone. Our Restoration teams are well versed in best practice and working as much on Stucco and Lime render projects as well as they do on Portland stone, Yorkstone and Granite buildings. We have carried out significant restoration projects on prestigious Grade I Listed estates such as “Cliveden House” and “Dropmore Park” and stucco rendering on grand private houses such as “47 Belgrave Square” and “115 Eaton Square”, in London. In 2015, we restored the “Bank of England”, a project which included cleaning, restoration, stone carving and leadwork. Globally, we have cleaned three UNESCO World Heritage Sites and hundreds of the world’s most famous buildings, such as the “Kremlin Palace Hall”, “Canadian Parliament” and the “Louvre Museum”. In 2014, we were employed by the State of New York as one of just three companies allowed to carry out trial cleans on the 3500-year-old “New York Obelisk”, all of which were highly successful.
The most secure plan For obvious reasons, security is a key concern for banks. As a result, a scaffold-free system is by far the preferred solution for cleaning the exterior of a bank, as it offers increased security as well as guaranteeing minimal disruption to visitors and employees alike.
The Portland stone was cleaned by façade gommage® and any damaged stone replaced by masons from the Thomann-Hanry®’s Restoration team. Sections of leadwork were also repaired. Our interior stonework division – Specialist Stone Care – restored and cleaned the Terrazzo walls within the archive room that had been locked away, undiscovered for over half a century.

Scaffold-free façade cleaning and restoration Façade gommage® cleans masonry sensitively and without abrasion. Building façades are visible to the public at all times and visitor’s experience remains unaffected.
Thomann-Hanry® have cleaned the façade of Gibb’s Building in King’s College, Cambridge, using façade gommage®, refurbished and redecorated every timber window, metal grill and the underside of the central archway passage. In addition, the stonework was restored to a high level, including the supply and installation of new Portland stone balustres to match existing.

London’s finest hotels receive the five-star treatment from Thomann-Hanry® The Ritz Hotel’s management selected Thomann-Hanry®’s façade gommage® cleaning system to bring the building back up to the hotel’s impeccably high standards. 3,600m2 of Portland stone and Cornish grey Granite – including intricate moulding and decorative carving – was cleaned in just three weeks.
The summer season brings great business for the hotel industry, with rooms fully booked and visitor numbers spiking significantly. But what would happen if your hotel or building required an exterior revamp, resulting in it being covered in scaffolding? The beauty of Thomann-Hanry®’s unique system is that cleaning can take place during specific times due to the quick set up and speed of cleaning, meaning guests aren’t inconvenienced, and clients don’t think the premises are closed.
• Cleaning is fast and non-intrusive. • Business can function as usual. • No loss of revenue. • Minimal or zero disruption to guests and employees.

Superior quality in internal stone care The floor covering is the most important area in any building and acts as an integral part of its design. If the first impression is that the floor is smooth and clean, most people assume that the building is well maintained, which conveys an organisation’s operating culture and, most importantly, the care for the people within it. Specialist Stone Care is Thomann-Hanry®’s interior stonework division, which works with natural stone and offers extensive knowledge of different cleaning processes, products and impregnators. Our technicians can restore all natural and man-made stone floors and surfaces. Led by industry expert Kevin Hooper, who has over 30 years’ experience in the industry, our technicians have benefited decades of experience of cleaning interior stone. The team frequently focus on the maintenance of flooring, often in areas with high footfall.
Specialist Stone Care can survey the flooring throughout your portfolio and provide detailed recommendations, not only for initial restoration but also advise and implement periodic maintenance cleaning programmes to your teams.
• S pecialists in the restoration, repair, polishing and maintenance of all natural and man-made stone.
• W e employ experienced operatives who have industry recognised accreditations. Unsuitable stone cleaning methods can cause irreparable damage, so it’s essential that specialist operatives are used to ensure that your property investment is in safe hands.
• W e also offer an all-in-one invisible surface protection range called Aqua Fend®. This shields floors, walls and other surfaces against long-term damage, ensuring easy ongoing cleaning and maintenance.
Cleaning and resealing stone surfaces The use of natural stone in the commercial environment continues to grow year on year and periodic maintenance is critical to its appearance and longevity. Combined with high traffic and lack of proper maintenance, grease and dirt are detrimental factors which can significantly contribute to the dramatic deterioration of stone surfaces. Once restored, the correct programme for daily cleaning is essential not only to maintain the stone’s natural appearance, but also to prevent permanent staining. Stains can cause disfiguration, grout can decay, and a build-up of ingrained dust and grime will cause the stone to lose its natural sheen. “Internal stone flooring, staircases and decorative features can be incredibly beautiful. However, much like anything else, if left uncared for, the cost of maintenance and ultimately restoration can prove exceptionally expensive. A key example of this is when the wrong chemicals are used for cleaning stonework – a very common issue that can arise even when employing reputable cleaning or maintenance companies. It is often not appreciated that, depending upon the type of stone, different chemicals are required for the cleaning process.” Kevin Hooper, Head of Specialist Stone Care.
All-in-one invisible surface protection Reduce cleaning and maintenance costs while keeping your walls and floors clean Once building surfaces have been cleaned and restored, they should be protected against future weathering and deterioration. The primary concern is to prevent the build-up of dirt particles and damp, which can react with the masonry and reduce its lifespan. Protecting surfaces also extends the cleaning cycle. Aqua Fend速 impregnation products offer the highest grade of surface protection. Aqua Fend速 effectively protects concrete and stone surfaces, forming an impenetrable but breathable barrier against contaminants without affecting surface colour. As the capillaries of the surface are protected, contaminants will sit on top, allowing them to be removed by basic cleaning operations. Thanks to Aqua Fend速, pollution, oil, grime, grease, bird droppings, algae and other surface contaminants are no longer an issue or expensive to remedy. Aqua Fend速 range now includes four exclusive products that are specifically designed to protect buildings, pavements and floors against a multitude of unwanted contaminants.

Unlike other products, our formulation does not break down under intensive cleaning and offers an unmatched life expectancy of twenty years on façades. Product performance can be guaranteed by way of a ten-year insurance backed warranty.
