Welcome to Cornerstone Cleaning.
The Home of Solid, Dependable Service.

We are a family-owned business with over 30 years of combined professional cleaning experience, offering a variety of services to small businesses throughout Rhode Island. Co-founders Robert D’Ordine and Salvatore Butera’s love for cleaning started from working in the casino cleaning industry, where they both held supervisory roles leading their workforce to success. Bobby and Sal have been professionally trained in areas such as conventional and green cleaning products, industrial cleaning equipment and techniques, OSHA laws and regulations, bloodborne pathogens, and more. Together they have taken their wealth of knowledge, experience, and leadership to the world of commercial cleaning to form Cornerstone Cleaning Services.

About Us


During the course of the day, your place of business can become soiled and unsanitary. Your workplace is a reflection of your business and an establishment that is not properly cleaned and sanitized could result in the potential loss of clientele. Your employees are the driving force behind your business, an unsanitary work environment could lead to frequent employee absences and ultimately a depleted workforce. We are here to help!


All offices need a system to get them clean and there are many different factors that come into play, such as the busyness of your workplace, number of employees, hours of operation, type of business, and office layout, just to name a few. Cornerstone Cleaning Services will design a cleaning regiment specific to your needs.


Between foot traffic bringing in all types of dirt and debris, including sand and salt from a harsh New England winter, and everyday spills such as food, drinks, gum, and ink your carpet takes a beating! Among the many industry approved methods that we use the two most common are Encapsulation and Hot Water Extraction.


There isn’t anything more satisfying to us at Cornerstone Cleaning than taking a tired and worn out VCT floor and transforming it to look like a polished and shining gem. Vinyl Composite Tile (VCT) is a common choice of flooring in commercial buildings most commonly found in restrooms, kitchens, exam rooms, and hallways.


Our extensive window washing process includes; the removal of any debris stuck to windows, washing and squeegeeing of windows, and the cleaning of all ledges and sills—leaving you with streak free windows sure to shine.


Cornerstone Cleaning can take care of all of your pressure washing needs. Whether it is your parking lot, walkways, stairs, decks, awnings, or the exterior of your building, our pressure washing will wash away all the unsightly dirt and grime.


Spend less time ordering and picking up your everyday consumable products and more time focusing on what matters the most—your business. Let us take care of the ordering, delivery, and stocking of all your products.

These guys are extremely professional, friendly, thorough and don’t miss an opportunity to impress. Thanks for making our company look better!
