Troika has provided professional exterior cleaning and restoration services since 1998. Our team combines drone-assisted cleaning with proven traditional methods to match the needs of each building, surface, and trouble area. Drone systems can improve access and efficiency on many mid-rise commercial buildings, while ground cleaning, lift work, and rappelling remain available for stubborn stains or areas that need direct attention. We clean and rinse windows and facades with purified water that dries without leaving mineral water spots. Surface-specific methods help us work carefully around stone, masonry, concrete, glass, metal, roofing, siding, and specialty materials. Every project is evaluated for access, weather, safety, water, surface condition, and the level of cleaning required.
