Historic building preservation often includes facade conservation and the cleaning surfaces to help restore the original appearance. Laser ablation, also called photo ablation or laser cleaning, is a relatively new technology that provides a way to clean historic surfaces in a safer, less invasive, and more environmentally friendly way.
Laser light is one of the most delicate and efficient means to removing certain types of soiling on historic buildings, monuments, and sculptures. The concentrated energy of the 1064nm Nd:YAG Q-switched laser removes buildup without damage, leaving even very delicate materials clean and intact—perfect for historic surfaces, and environmentally friendly too. Our team has used laser cleaning on some of the most significant historic properties in North America, including the U.S. Capitol and Jefferson Memorial.
Laser cleaning technology continues to evolve and training and education is important. Our laser experts are certified by the Laser Institute of America as either Laser Safety Officers and or Class IV Laser Operators on the safe application of laser on a wide range of historic materials. We have a pool of 100 watt and 500 watt portable lasers for a broad spectrum of conditions. We look forward to assisting you on your next project.
