Regular façade maintenance is important. Contaminants that build up over time can find ways to penetrate the surface, causing structural deterioration, fractures, and corrosion. Wind, temperature fluctuation, and humidity levels affect the rate at which pollutants and deposits accumulate contribute to the deterioration.
There is more than one approach to cleaning historic building surfaces. The unique composition of the substrate and the soiling determines the best approach. What may be a safe and effective for the treatment of certain stains or materials may be too harsh or leave discolorations on another. Reactions can occur immediately or gradually in a delayed reaction. Investigation, testing, and analysis is typically recommended to find the most suitable approach. The versatility of modern laser technology as well as high capacity steam can offer a safer, less invasive, and more environmentally friendly options in certain cases.
If neglected, façades can also present a safety hazard. Severe stone and mortar disintegration can resulted in the loss of architectural elements and sculpture, posing a potential risk to the public. Our conservators can carry-out the required surveys and translate data into scope drawings when planning specific conservation treatments and direct planning and implementation during the building’s restoration.
