A complete access solution for rendered façade cleaning projects

If you are a surveyor, architect or property manager searching for a range of sensitive and approved render cleaning solutions which will restore your property back to its former lustre (whilst ensuring the long-term integrity of the building fabric is retained), speak to a member of our specialist render restoration team today.

We provide a complete solution for cleaning render, repairing and protecting render along with other building façade materials such as stone, brick, concrete and architectural cladding. Cleaning any building façade is a delicate and sensitive process. With render you must try to limit the cleaning programme and pressures applied to the substrate to help preserves it integrity for the future. Time and time again we see new rendered facades suffocated with algae, over-cleaned and in a state of decay due to poor and generally ill-considered practice, a lack of attention paid to the renders long-term performance.

Managing organic and visually unattractive growth on the rendered façade is simple, plus it reduces the need to clean the building as the treatment targets and removes the root causes of the discoloration and decay on the rendered facade. We apply a product that absorbed into the render and breakdown the algae, lichen and moss spoors if working on a roof by puncturing microorganisms cell walls. It does not interact with the mineral components of self-finished renders and does not contain any compound deleterious to the colouring agents or the surface cohesion. On porous render, the surfactant active will decontaminate deep into the surface porosity by capillary action and can then be treated with a light steam clean to create the final product. If the render is also affected by carbon and environmental pollutants a light, but phased steam clean using 150degree steam is the most effective to help achieve the desired end result.

As modern architecture pushes the boundaries of material design and performance, the need to take greater care of the building fabric increases. We use hot water cleaning, low pressure cleaning, Torik and steam cleaning methods to restore, preserve and maintain soiled building façades and exteriors on old, modern and new buildings through-out the UK. We only sensitively clean external buildings, removing staining such as carbon, traffic film, effluence staining, leeched salts, organic matter, environmental pollution and paint from your stone, concrete, brick, rendered or cladded building façade.

Kerry Quinn - Echo Arena

Customer service is paramount to Building Transformation and they invested vast amounts of time in providing me with a programme to facilitate what was a very complex and time-specific programme of work for the site. The quality and level of support provided by Building Transformation is priceless to any client/contractor.

Marc Blow MCIOB MBIFM - Carillion Amey

The approach and advice on setting up the works at the Wolverhampton Civic Centre were first-class. Building Transformation’s attention to detail was excellent and the RAMS were followed meticulously to every detail. We were delighted with the works and service, and would not hesitate to use them again, nor hesitate to recommend them to any organisation.

Kevin Egginton - Wolverhampton Council

A 200,000 sq. ft., four-storey leisure venue in the heart of Nottingham city centre surrounded by major traffic routes needed work to be done overnight to deal with the traffic issues, while the site remained open throughout. The project took around three weeks to complete and went exceptionally well; the Building Transformation staff were flexible and able to work round dynamic operational issues. The clean was of a high standard and has made a significant different to the image of the building. A very difficult job done well.

Suzanne Green - Land Securities

May & Co have worked with Building Transformation on a number of projects which have included external building cleaning and refurbishment. They provided a great service, supported by the high level of documentation from the initial quotation to books and industry-related guidance, all relevant to our project.

Our Philosophy

21st Century Façades: Breathing Life into Urban Landscapes

The urban environment has changed enormously since the majority of building maintenance concerns were focused on more traditional masonry structures, materials, pollution levels, weather patterns – even the height of most buildings are completely different to a hundred years ago. This book illustrates how Building Transformation’s methods breathe new life, energy and vitality into building skins and cities.
