We do not use harsh detergents or abrasive cleaning materials. We provide our services to both residential homes and commercial businesses throughout the city of Chicago, North Shore and the South West Suburbs.
Cast stone is a porous cement manufactured from natural sands, carefully crushed stone, gravels, minerals, and pigments combined to achieve a color and architectural look often used in exterior parts of masonry on a building. It behaves similar to cement in that if not cleaned and sealed, the surface will hold soil and is susceptible to staining. In fact, in high moisture areas, it is common to find mold, mildew and microbial growth staining, and in worst case scenarios, cast stone will erode from water damage in states that have harsh winter climates.
Therefore CSI-Absolute Clean Inc. can help you preserve the beauty of your cast stone and prevent permanent staining and even water damage. Our skilled and experienced technicians will ensure proper care is taken when cleaning your cast stone and revitalizing it to the way it was meant to look.
