Thanks to atmospheric pollutants, biological growth, algae, or other stains caused by moisture or prolonged dampness, at some point in a building’s life exterior cleaning must take place.
Façade cleaning, especially on historically significant structures, can be very demanding and should be completed by a contractor with a vast knowledge of cleaning procedures and experience in historical preservation is a must.
Cleaning can be accomplished in various methods, from chemical cleaning to water soak cleaning without the assistance of chemicals. Cleaning using the assistance of chemicals is completed now using only materials which are bio- degradable and environmentally acceptable.
Masonry, stone or terra cotta should be cleaned using the gentlest method possible. To avoid further deterioration of mortar joints or friable surfaces techniques such as low pressure water and hand brushing should be employed.
Cleaning of historically significant structures should be cleaned following the recommendations of the National Parks Service Guidelines.
Schnell Contractors, Inc. has cleaned a great deal of masonry, stone and terra cotta buildings. Cleaning should only be used to halt deterioration of masonry surfaces or remove heavy deposits of pollution or biological growth. Cleaning can also be employed to remove paint from a surface, restoring masonry to its original condition.
