Janitorial Services in Stony Brook, NY

From Route 25A (Main Street) to Nicolls Road (CR 97), Stony Brook property managers and business owners choose Lupes Cleaning Services for professional janitorial services. Since 2003, our team (Stony Brook is about 20 minutes from our Medford headquarters) has delivered janitorial services to academic and technology tenants, along with retail plazas on Route 347. Every program starts with a free on-site walkthrough so we understand your square footage, foot traffic, operating hours and the specific surfaces in your building before we write a single line of the scope of work.

Our Stony Brook janitorial services crews regularly work along Nesconset Highway (Route 347) and near Long Island High Technology Incubator, serving ZIP codes 11790, 11794 (Stony Brook University), 11733 (Setauket–East Setauket). We clean offices, warehouses & distribution, gyms & fitness centers, schools, retail and more, using EPA-registered products, HEPA-filtered equipment and color-coded microfiber to deliver hygienic, inspection-ready results that are consistent from one visit to the next.

Stony Brook facilities face local conditions that generic cleaning companies overlook: heavy spring pollen and academic-calendar traffic surges. Entrance mats, lobbies and restrooms need extra attention during Long Island's winter months. This local knowledge is why our janitorial services in Stony Brook last longer between deep cleanings and keep your floors, glass and restrooms in better condition all year.

As a licensed, bonded and insured Suffolk County contractor, Lupes Cleaning Services gives Stony Brook clients written checklists, supervisor quality inspections, backup staffing and a guaranteed response within 24 hours. Whether you need 5–7 nights per week or custom schedules, we design a schedule and a transparent price that fit your Stony Brook business.
