Sentinel Cleaning Company

Sentinel Cleaning Company is a Hyannis-based house cleaner that Priscilla Barbosa says she started in 2008, putting the business at about 17 years old by her own account. It covers a wide stretch of Cape Cod — Hyannis, Barnstable, Centerville, Chatham, Harwich, Mashpee, Osterville, the Yarmouths and more — handling house cleaning, vacation-rental turnovers, move-in/move-out jobs, carpet extraction, hard-floor care and window cleaning. What stands out across its fifteen Google reviews is how long some of these relationships run. One customer says Priscilla and her team have cleaned their home for nearly 20 years; another for almost 10; a third for five. Several describe standing monthly visits — one homeowner budgets three to four hours per cleaning — and the detail people keep singling out is the same: dusting, vacuuming and floors done thoroughly enough that, as one reviewer put it, they never need to do a spring clean of their own. A few reviews name specific crew members, Rosineia and Alcione, suggesting a small, consistent team rather than rotating cleaners. Every review on file is five stars, and Google's own rating sits at 4.9 from 20 ratings. There isn't much to flag before calling — no complaint turns up anywhere in the fifteen reviews, and several customers name Priscilla Barbosa directly as easy to reach and organized about scheduling. For anyone on Cape Cod looking for a recurring house cleaner rather than a one-off deep clean, this reads as the kind of company people keep for years rather than switch away from — worth a call to confirm current availability and pricing for your specific area.
