Most buildings have exteriors  consisting of brick, vinyl siding, aluminum siding, stone, masonry, or cedar. Up to now, high pressure washing with bleaching agents and acid cleaning were the only method to clean these surfaces. Besides being harmful to the environment, these products actually damage the surface. Vinyl becomes chalky with bleach.  High pressure acid cleaning damages the brick by pitting it, and it can burn the brick, turning it to an orange color.

Envirotech's environmentally safe system solves these problems and makes exterior surfaces look like new. In one step,we clean and restore all the above surfaces by removing the unsightly mold, mildew, dirt, chalkiness,pollution,andenvironmental
