Priscilla Barbosa is the founder and owner of Sentinel Cleaning Company. She has been running the company since 2008 with a hands-on approach, and many long-term clients mention her by name in their reviews.

Sentinel is locally owned and operated, not a franchise. That means personalized service, direct communication with the owner, and cleaning plans tailored specifically to each client. No scripts, no one-size-fits-all checklists.

Yes. Our seasonal closing clean empties and sanitizes the refrigerator and appliances, cleans every surface, washes floors and leaves the home ready to sit empty through the winter. We can do it while you are off Cape and coordinate access with you or your property manager.
