Commercial Cleaning Services in Newark, DE

Newark businesses — from Main Street offices and University of Delaware facilities to STAR Campus labs and Glasgow Business Community manufacturing floors — can’t afford a cleaning company that treats every facility the same. One missed disinfection cycle in a medical office, one visibly dirty lobby in a corporate building, or one unaddressed spill in a high-traffic retail space is enough to cost you a client or a lease renewal. 

JAN-PRO Cleaning & Disinfecting in New Castle has delivered customized commercial cleaning programs to Newark, DE businesses for over 30 years. Our certified local franchisees build every cleaning plan around your facility, your industry, and your schedule — not a generic package.

Who We Serve in Newark, Delaware

Newark’s economy spans life sciences, healthcare, education, advanced manufacturing, and financial services — industries with very different cleaning and sanitation requirements. JAN-PRO’s certified franchisees are trained to meet the standards of each.

Corporate Offices & Professional Services

From Main Street businesses and Downtown Newark Partnership members to multi-tenant office buildings and financial services firms, we provide recurring janitorial service, high-touch surface disinfection, and day porter coverage that keeps professional environments consistently clean without disrupting your team’s workday.

Biotech, Life Sciences & Laboratory Facilities

Newark is home to major research and manufacturing operations — including facilities tied to AstraZeneca, W.L. Gore & Associates, Siemens Healthineers at the Glasgow Business Community, and the 30+ companies housed at the University of Delaware’s 272-acre STAR Campus. These environments demand precision cleaning with EPA-registered disinfectants, strict protocol compliance, and vetted, background-checked service providers. That is exactly what JAN-PRO delivers.

Medical & Healthcare Facilities

Newark is anchored by ChristianaCare — Delaware’s largest healthcare provider — and surrounded by medical offices, outpatient clinics, and specialty practices serving New Castle County. Our medical facility cleaning programs comply with OSHA and CDC standards, using hospital-grade disinfectants in exam rooms, waiting areas, and patient-facing spaces to reduce cross-contamination risk.

Educational Institutions

The University of Delaware enrolls more than 24,400 students in Newark, making cleanliness and infection control a year-round operational priority. From UD facilities to schools in the Christina School District, JAN-PRO provides daily cleaning using non-toxic, student-safe products — with electrostatic disinfection available for high-traffic areas during cold and flu season.

Industrial & Manufacturing Facilities

Newark’s industrial parks — including the Sandy Brae Industrial Park and facilities in the Glasgow Business Community — house manufacturers and engineering firms with heavy foot traffic, production floors, and specialized facility needs. We provide industrial cleaning programs scaled to the demands of these environments.

Retail, Restaurants & Hospitality

The shops, restaurants, and hospitality businesses along Main Street and throughout Newark’s downtown district benefit from flexible cleaning schedules designed around business hours — early morning, evening, or weekend service that does not interfere with customer-facing operations.
