Just had my first experience with CSI and will definitely use them again in the future. I had them strip, clean, and seal slate floors in our kitchen and ceramic tile and grout in our bathroom. The tile and grout were both very dirty. First, I really liked their website and how they introduce you to all their employees. A company that spends the time showing off their employees definitely cares about them. The estimate guy, Earl, was very nice. He seemed to be very knowledgeable. I do wish he would have explained my options for sealants more, as I knew nothing about this. I received the estimate a few days later and was actually able to schedule the work the next week. When the technicians showed up I saw that they held true to what the website showed -- they really were friendly and passionate about the work they were doing. They spent time talking to me and showing me the options. They even did a few example test areas on my floor so I could see what it looked like. I learned so much from talking to them that I decided to use a different type of sealant. The job ended up looking better than I expected. Plus, they finished 4 hours earlier than expected. The office promptly gave me a credit for the difference in labor and supplies. I would definitely use them again. My only advice would be to make sure you do a little research ahead of time if you are getting your floors sealed like I was. These guys know what they are talking about and you will definitely be able to get exactly what you want done at a good price. Also, I was really impressed too with how clean they were. They noticed there was some dirt left on the floor and they cleaned it up right away without me having to even ask. They were super polite too. Great job and great company to work with! read more

The Mrs. and I finally had enough with the two dogs having their way with the bedroom carpet so we decided to give these guys at CSI a shot at removing the stains and odor left by these couple of crazed canines. I was very impressed from the moment I opened our door to them since I respect the fact they respected my home by putting on boot covers even before entering. Secondly, I loved the free in home carpet assesment and consultation which opened my eyes to the true condition of my carpet. Burning carpet fibers, smell test to determine which chemicals can and cannot be used for treatment, a sweeping black light over affected areas not seen with the naked eye, a microscopic inspection of carpet fibers also helped determine there was no further damage - all done before an estimate was even written! And, all the while Free!! Any other company would have easily charged at least $100 just to let them through my door to inspect!! These guys were very honest in educating us on what we really needed done. They're very confident in the job they can accomplish and their work showed in the end result. The dog made, lightly brownish - yellow, polkadot carpet (*insert vomit sound*) is now white again!! Whoohoo! These past few nights, sleep has been the best in a long time. A very thorough, very professional, no gimmick run company. One can't go wrong with using CSI; I'd highly recommend them to anyone who needs any cleaning services. read more

Recently, we had a master bathroom updated and an expensive marble floor and shower surround installed. The contractor did a horrendous job and scratched, scraped and gouged the entire surface of the tile, both floor and walls. Cesar Reyes, CSI Field Operations Manger, came out to the house to assess the situation. He suspected, along with the mishandling of the tile by the contractor, that the tile itself had some type of coating on it. He took a tile back to the workroom to perform testing on it, so he could assess what action to take next. After performing several different tests, Cesar made a second appointment to meet and provide us detailed explanations of his experiments and findings. Unfortunately, the findings provided to us confirmed the tile is irreparable due to a baked coating the manufacturer used on the marble. I can't think of any other situation where a company and its employees would go to this extent of service; filming the experiments on the product, providing a written summary and simply spending the amount of time they did, knowing there was an issue with the product that is unsolvable. We were so impressed that they were honest and did not try to sell us on a repair attempt because they knew it would not work. We very much appreciate the time and efforts and will be sure to recommend and use them for any future projects. read more

CSI-Absolute Clean has never ceased to amaze me, they are competively priced, all there employees are very highly skilled at what they do.

Cesar, Earl and there crew, make the carpets always look like new again and again, and always go out of there way to do so for the last 5 years now and still counting.

Believe me, you can not go wrong with CSI-Absolute Clean at all. Thank God for very responsible people like Cesar and Earl, and there very skilled capable employees.

My name is Glen Bero. I live in Addison, IL. I had CSI-Absolute Clean come out and clean all the cream color carpeting in my condo. I have been living in this XL Condo for 4 years. We have two teenage daughters, two cats and a lot of foot traffic. We have tried to maintain it, but we decided that it was time to get it professionally cleaned. I called CSI-Absolute Clean and the first thing I noticed was that the customer service was very nice, informative and helpful. She took my information, gave me pricing and than emailed me work order and I was scheduled. The technician actually called me to tell me he was on his way and showed up on time. He put on booties, came into my home and went over the work order with me to verify all of the services I wanted. They were polite, friendly and they did an awesome job. My carpets looked great, better than the day we moved in. Thank you CSI GB read more

It's so hard to find good servicemen nowadays. I must've made mutliple calls to different carpet cleaners before i received a straight answer. A friend suggested I called CSI. So i did. At this point what did i have to lose? I'm glad I did. I provided them with a guesstimate of the sizes of the rooms I needed cleaned and I was given a rough estimate. At first the price kind of struck me as high, because of all of the advertisements given by other cleaners, but then I was informed of no extras. The price they gave me included everything the other companies were trying to upsell me. Their price was all inclusive. Long story short, I gave them a shot. They were very courteous, polite, communicated very well, answered all my questions and concerns, and if that wasn't enough, they were on time! The service provided was phenomenol. I'm definitely going to be a repeat customer. read more

CSI-Absolute Clean services are excellent! We have a full house of kids and pets that's run down our floors & carpet to a desperate need of a very good cleaning. I have come across their website that was recommended from a coworker which in turn lead me to try them out. When I had contacted them they were professional about explaining what services they can provide and very patient and flexible in scheduling an appointment. When they arrived at my home the workers were very proficient and skillfully sharp with the job. Since then I have been needing their services for just about everything they can accommodate. Great customer service are key aspects that I really look into, and CSI definitely provides that kind of consistency. read more

He is one fantastic contractor! He's meticulous about cleaning up after working each day. He's courteous and explains what and why he's doing what he's doing. He goes the extra mile to do things right the first time...so you don't have trouble later on down the road. I think his prices are very competitive and reasonable...he works hard...and you get your money's worth out of him. I will definitely use his company again to do other remodeling jobs for me...can't say enough good things about him and his company...I highly recommend using his services...you'll be glad you did! By the way...my bathroom looks downright awesome!!! Thanks again read more

I just had a really positive experience with this company and I am writing my first yelp review! They came to clean the slate tiles in my bathroom but when they got here they discovered that the tiles could not be cleaned until a wax coating was stripped off and then the tile would need to be resealed. They were very honest with me and explained that what I needed done would be more expensive than what I had expected. Although I decided to wait on getting the tile stripped and sealed, they still cleaned up the shower tile free of charge. I will certainly call them back when I save up a little to have complete job done. read more

I highly recommend CSI Absolute Clean! I had my carpets cleaned by Andre and Saul from CSI Absolute Clean yesterday. They arrived a few minutes ahead of schedule with appropriate protective gear, which put me at ease right away. Andre reviewed the carpets I wanted cleaned, let me know the plan of action, then the guys started spot treating and cleaning my carpets. When the work was finished, I was amazed at how clean the carpets were and how thoroughly and quickly the job got done. Thank you to Teri and the helpful team at CSI for making the service I received smooth and easy from the first phone call! read more

These guys are great! Very proffesional, upfront with pricing, no pushy sales, excellent craftmanship. I've never seen any cleaner come in the way they do, they are very passionate about their work. I used them for carpet cleaning, but ended up purchasing the anti-allergen package due to my asthma, and it is definately effective. I have 3 dogs, and a baby. I was most impressed by their pre-inspection, cause they show you exactly what conditon your stuff is in. Not to mention the queen mattress they cleaned for me. Thanks CSI! I will see you again at my next scheduled cleaning date. read more

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 !! Thanks Jim read more

Great experience. As promised, I received great service at a great price. My 50-yr. old marble floor has been restored to a beautiful shine. The guys were neat, considerate, hard-working, careful of my walls and adjoining wood floors. I was surprised when my salesman, Cesar, showed up in the middle of the day to check out how everything was proceeding. I will use them again for my bathroom floors without hesitation. There are too many below average companies and workers out there. CSI is clearly ABOVE average! Thank you CSI. read more

had some acid-etched spots on our marble floor tiles in two bathrooms. Called the company, they responded quickly, set up a time, and I was met by Carlos this afternoon. He was good about calling ahead of time to coordinate (I was coming from down town). He spent a lot of time with the areas and was careful in taking off his shoes in our house. He did a very nice job and got the spots out and re-sealed the tiles. The service and quality were top notch. I would use them again. read more

I'm in the process of moving and it's shocking how hard it is to get good service, and sometimes even a call back, when you're paying someone. CSI was a breath of fresh air. They were thorough, effective, friendly, responsive, on time and did exactly what they said they would do. They cleaned marble vanities, wood floors, slate floors and carpets. I canceled with 2 other companies because CSI did all of it. I highly recommend them. read more

Kathie I. 1/29/2019 job. Angel did a wonderful job cleaning and sealing our large shower! He was professional and honest--which I deeply appreciated! It looks wonderful. Cesar completed our estimate, and was very honest and did not oversell the work we needed. What a breath of fresh air! We would definitely use their services again and highly recommend them to others. Lemont, IL read more

CSI is Great! They cleaned and buffed my travertine tile and grout and the result was a beautifully restored floor. I don't usually take the time to leave reviews but Angel and Saul absolutely deserve praise for their expertise and hard work. They worked all day with just a 20 minute break for lunch and the results were spectacular. I will definitely use CSI again. read more

CSI did the best job! I bought a condo with beautiful looking granite but it felt terrible, no matter what I did to improve the finish. From appointment to inspection to treatment, the service at CSI was exceptional. They did a phenomenal job at a fair price with professional and friendly service. I can't thank them enough and highly recommend! read more

I have a marble bathroom floor and large tub surround that has been in place 24 years that had some spots and cloudy areas. I am thrilled with the wonderful cleaning job and coating job the 2 men from CSI did last week. It really looks better than new. The 2 men not only did a wonderful job but were great to work with. Five stars for them. read more
