Janitorial Services in Port Jefferson, NY

Finding dependable janitorial services in Port Jefferson can be difficult, especially when your facility sits on a busy corridor like Main Street & East Main Street. Since 2003, our team (Port Jefferson is about 20 minutes north of our Medford headquarters) has delivered janitorial services to waterfront restaurants and inns, along with retail boutiques on Main Street. 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 Port Jefferson janitorial services crews regularly work along Route 112 (Port Jefferson Station) and near St. Charles Hospital, serving ZIP codes 11777, 11776 (Port Jefferson Station), 11778 (Rocky Point). 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.

Port Jefferson facilities face local conditions that generic cleaning companies overlook: harbor winds, salt air and summer tourist foot traffic. Warehouses and flex buildings in Hicksville, Medford and along the LIE corridor generate fine dust that requires frequent high and low dusting. This local knowledge is why our janitorial services in Port Jefferson 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 Port Jefferson 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 Port Jefferson business.
