Commercial Cleaning Services in Stony Brook, NY

Finding dependable commercial cleaning services in Stony Brook can be difficult, especially when your facility sits on a busy corridor like Route 25A (Main Street). Since 2003, our team (Stony Brook is about 20 minutes from our Medford headquarters) has delivered commercial cleaning services to medical and research offices near Stony Brook University Hospital, along with academic and technology tenants. 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 commercial cleaning crews regularly work along Nesconset Highway (Route 347) and near Stony Brook University Hospital, serving ZIP codes 11790, 11794 (Stony Brook University), 11733 (Setauket–East Setauket). We clean corporate offices, multi-tenant professional buildings, retail stores & showrooms, auto dealerships, banks & credit unions 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. South Shore and East End properties battle sand, salt air and high humidity that promote mildew and film on glass. We adjust glass, HVAC grille and restroom protocols seasonally. This local knowledge is why our commercial cleaning 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 nightly (5–7 nights per week) or one-time deep cleaning, we design a schedule and a transparent price that fit your Stony Brook business.
