Finding a good janitorial company in Chicago was harder than we thought. We wanted someone that we could trust and work with for the long term. Our Chicago location isn’t huge, but they treated us as if we were their largest client. They always come on time and work hard to make our offices and showroom professional and inviting. They’re always on top of things and we can count on Cosmopolitan to make sure that all of our cleaning and maintenance needs are meet.

Cosmopolitan has been maintaining our medical facilities and doctors offices for several years without incident. They especially helped up out when we required last-minute deep cleaning and disinfecting in a few of our Chicago out-patient facilities. Their people and expertise especially with medical exam offices really made our doctors and tenets feel comfortable during these times.

A customer recommended them to us almost 2 years ago, and weve been using them ever since. The place always looks great when theyre done. They do great work, and we couldnt be happier. More importantly, they always as us if they could be doing anything better, and frankly we can never think of anything. They do exactly what a great cleaning service should do. We would recommend them to anyone.

We have been using Cosmopolitans restaurant cleaning service ever since we opened our restaurant in Chicago. I realize they specialize in medical office cleaning, but restaurants need the same level of cleaning and attention to detail as any medical facility. Great work.

Been receiving services from this company for many years and they always go above and beyond my expectations. Even have referred them to others in the past. You can count on them too! Will always consider Cosmopolitan Building Services!

The service is very good and we are very happy with the outcome. Would recommend to anyone looking for a commercial cleaning service for their business.

I have used this company for my businesses and I highly recommend them, excellent job every time, great customer service
