Second-Generation Leadership. Forty Years of Delaware Service.


Founded in 1984, Bishop Cleaning began with a commitment to integrity and meticulous care. Over four decades, we've grown from a trusted local cleaning service to a comprehensive facility maintenance provider, now led by its second generation.
This evolution is grounded in continuous training, adopting cutting-edge technologies, and expanding our expertise to include specialized services like biohazard remediation and high-rise access, all while maintaining our core family values.
Certified Safety. Vetted Teams. Unwavering Accountability.
We believe in direct local accountability, ensuring every project meets the highest standards. Our teams are fully vetted, trained, and compliant with OSHA, IICRC, IWCA, and GBAC STAR protocols, guaranteeing peace of mind for every client.
