School, Hospital, & Hotel Exterior Cleaning Services

Institutional Pressure Washing in Chicago, Chicagoland, Northern Illinois, and Northwest Indiana

We, at McCahill Painting Company, are dedicated to providing the best services to our institutional clients. When your public or private institution is gearing up for a new school year or big public event, Chicagoland Pressure Washing can be there on short notice to improve the appearance of the front façade, sidewalks, and other public areas. We are your total restoration solution.


In addition to pressure washing, we also offer water repellant services. This is where we simply apply both water repellents and other clear sealers. For example, after we complete a limestone cleaning project many of our customers take our advice to seal and protect the limestone from future environmental contaminants.

Please consult this list to read more about some of our specialties that involve pressure washing.

Schools/ Universities

We have considerable experience with institutional pressure washing cleaning and restoration projects in establishments throughout the Chicagoland area and the Midwest. Our jobs range in size from cleaning the front sidewalk of a small private school to cleaning entire buildings at large universities and colleges. We are accustomed to working around class schedules. It is not unusual for Chicagoland Pressure Washing to complete projects during a winter break, spring break, or summer.

We also have a strong focus on high school and elementary school cleaning projects. In the photo below, we completed an interior brick cleaning job for De La Salle High School in Chicago. We took extra precautions to protect all substrates while doing an exceptional job! De La Salle later informed us the lighting in the gym increased substantially because of the drastic difference in the wall color after it was cleaned.


Church/ Historical

Chicagoland Pressure Washing also takes pride in completing church and historical restoration projects. This type of cleaning work requires a complete understanding of the substrates being cleaned, environmental considerations and the appropriate chemicals to be used in the cleaning process. Chicagoland Pressure Washing has more than 30 years of experience in this type of work.


A staple of our institutional cleaning and restoration business is hospitals. In addition to our cleaning expertise, we are experienced in effectively protecting hospital staff, patients and visitors. When our swing stages are erected on the side of a hospital building, we use the greatest care and respect when working around patient rooms. We make a concerted effort to avoid disturbing patients. Ideally, patients and residents will be unaware of our presence. Not disrupting operations is one of the many different aspects of our work that we take very seriously. Hinsdale Hospital is just one of many buildings where we applied a water repellent after the cleaning process to help secure the building for many years to come.

Other Sites

No project is too big or too small for us! We have also done work for various different organizations aside from hospitals, places of worship, and restaurants. Our experience is useful in a variety of different settings, as it depends more on the surface that needs to be cleaned. The same type of surfaces that would need to be cleaned house a variety of different businesses. We are highly skilled in power washing, making you happy that you chose us for your project!
