Daniel and his team have some of the best commercial cleaning expertise in all of Chicago. They are professional, quick, communicative and easy to work with. Highly recommended for any companies serious about having a pristine place of work.

Cortex Cleaning has been a great partner in maintaining our venue and studio. They are so knowledgable about the best options to clean and protect everything from our concrete floors to our furniture upholstery and everything in between. Daniel and team are extremely responsive and helpful in scheduling and offering up solutions to our expansive cleaning needs.

Bloom Events used Cortex Cleaning for their first event. They did an amazing job. They responded quickly to the initial request and answered all my emails in the same fashion. They are competitively priced. The staff showed up on time and completed the scope of work perfectly. I recommend them and we will be using them again in the future.
