CSI-Absolute Clean Inc. of Chicago has a well-earned reputation for top-notch cast stone cleaning, cast stone repair and cast stone sealing services specifically designed for exterior cast stone surfaces. 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.
At CSI-Absolute Clean Inc, we provide professional cast stone cleaning, sealing and repair services. Maintaining the beauty of your cast stone is our specialty. Our extensive knowledge and experience in cast stone cleaning and cast stone repair has made our company one of the leaders in the Chicago & Chicago land area.

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.

Good, bad or indifferent, we love all the feedback we receive from our clients. Though we love to hear how great we are...it is from our shortcomings that we grow the most as a company. We thank all our clients for taking the time to leave a review as it is our guiding post to continue to improve.
Impressed with every part of this company. Superior customer service, friendly and polite staff including office and scheduling. Our free inspection and estimate by Cesar was informative and comprehensive. He was patient and willing to answer any questions and concerns. The technician Angel called ahead to give us an accurate arrival time. He was a pleasure. His work was excellent.
Every step of the way, CSI Absolute Clean has proven to be among the best companies I've ever interacted with. Of any kind. They deserve your business. I can't say enough how I recommend them. I know I'm gushing, but they deserve it.
CSI is the best! They do an outstanding job at a very reasonable price. They are all such a pleasure to work with and have restored my stone back to a perfect state. Highly recommend!!
We got our marble island and marble floors polished and they never looked better, this is the third time using CSI for this service and I have to say, this time I feel they did an excellent job, Angel is a professional in what he does, he was always making sure we were happy with the results, he was dedicated and care for every detail, the prior time we used CSI I didn't like the job they did, my flors had a dull looking in some parts and I am not sure if they actually sealed them because they got bad fast, but his time with Angel everything looks amazing, he made sure we got the finish we liked and we got so many complements about our island.
If you use CSI ask for Angel and his parters.
