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.

Pre-Treatment: spray application of our alkaline trimix chemical with the purpose of breaking the surface tension of the soil, penetrating the grout in order to defloculate imbedded soil. It then breaks down soil and suspends it in the water molecule/cleaning detergent for easy removal.
Agitation: Manual or Mechanical – Aids the Pre-Treatment to saturate, and helps further loosen soil.
Extract: done via truck mount or portable machine vacuums off suspended soil in water molecules
Rinse: Triple Steam rinse flushes out any dirt remaining in the tile & grout ensuring full removal.
Emulsify: a chemical rinse that is the 2nd rinse step synergistically reacts with the pre-treatment to attract all chemical and soil to the surface
Neutralize: a chemical rinse that is the 3rd step in the rinse step that flushes all residue and solutions out, neutralizes them, and brings the tile & grout PH back to balance PH7 to prevent re-soiling.
Speed dry: expedite drying to eliminate/avoid efflorescence
Dry Buff: Removes any remaining residue, also aids to expedite drying
Seal: Application of appropriate deep impregnating/penetrating sealer. (sealers may vary depending on the type of stone)
Final Buff: Ensures full penetration of sealer, removes any excess sealer residue.

I just had CSI redo my bathroom marble floor which had become etching in it and I am blown away by how good a job they do.
Raul was one of the best tradesmen I have ever had the pleasure of working with.
I don't ever write reviews but the caliber of work, professionalism and just all round wonderful experience makes this review necessary
If you have any marble/ stone or some other issues you want fixed call CSI - wish we had done this over 12 months ago!!
I had a very good experience with CSI. They helped me to save black marble that was ruined by acidic cleaner. Stone looks like new! They are easy to reach over email, they provide a free estimate, they also show up on time! Most important they do a great job! Very professional! I'm glad I went with this company!!!
Andre was outstanding. The actual price he charged was significantly lower than the estimate due to the condition of my marble bath (talk about honest). He was right on time, super efficient, thorough and careful (put up lots of plastic and covers on his shoes). The results exceeded my expectations, so I asked him of he could squeeze in the kitchen before he left. For a nominal fee he polished up my kitchen counter & island. On Monday morning I received an updated invoice with detailed listings of the price changes. Nice job !!
