Historic building rehabilitation often includes surface cleaning to help restore original performance characteristics and appearance. New technologies, particularly laser ablation, provide opportunities for cleaning historic surfaces that are safer, less invasive, and more environmentally friendly.
Cleaning using laser light can be the most delicate and efficient means of removing certain types of soiling on historic buildings, monuments, and sculptures. The concentrated energy of the 1064nm Nd:YAG Q-switched laser light removes buildup without damage, leaving even very delicate materials clean and intact. This is what makes laser cleaning perfect for cleaning historic surfaces. This method has the added benefit of being environmentally friendly. Our team has used laser cleaning in some of the most significant buildings in North America, including the US Capitol and the Canadian Houses of Parliament West Block and the Jefferson Memorial.
Laser cleaning technology continues to evolve, but our team keeps up with developments through constant training. Our staff includes Laser Institute of America Certified Laser Safety Officers and trained Class IV Laser Operators certified and experienced with safe applications of lasers on a range of historic materials. We have a pool of 100 watt and 500 watt portable lasers that can be used to work in a broad variety of conditions. The use of this technology is exciting and continues to grow. We are eager to apply it to any number of new and challenging projects. Work with us to determine how laser ablation can work for you.
