520 Cleaning Solutions

The name that keeps surfacing in 520 Cleaning Solutions' reviews isn't the company's — it's Carol's. Customers write about her by name, and several of them have been writing about her for years. The company works out of Bridgewater and covers a wide slice of eastern Massachusetts, from the South Shore towns up through Boston, Cambridge and Somerville, doing recurring house cleaning along with deep cleans, move-in/move-out turns, post-construction cleanup and office work. It says it has been at this for over seven years, originally trading as Carol's Cleaning before renaming through the pandemic, and its site describes founder Carol as a Brazilian entrepreneur who built the business after coming to the United States. On Google the tally is 5 stars across 40 ratings, but the more useful part is the tenure inside those reviews. A customer writing in May 2025 said they had been with the company for over five years; another in November 2024 counted more than ten, spanning “one puppy, three babies (who are now messy tweens) and one move from the city out to the suburbs.” Speed is the other repeated theme. A January 2025 reviewer called for a deep clean and was fit in the next day. A November 2024 customer who had just moved said Larissa, Tatiana and Marcia turned up two hours after the phone call and cleaned out the old apartment. A real-estate agent, also writing in November 2024, said they bring the crew in to clean homes for buyers at closing and to prep listings before they go on the market. The paperwork is younger than the story, and that gap is worth understanding before you book. Its BBB profile lists 520 Cleaning Solutions, LLC as started and incorporated on 7/3/2024, two years in business, one employee, and not accredited — its A grade there rests on length of time operating, not on customer reviews, of which BBB has none. BBB also names Ana DaCosta as manager, while the website and the reviewers point to Carol, whom a couple of customers call Carolina. The “AHA Accredited” badge on the site is the company's own claim. House cleaning isn't a trade Massachusetts registers, so there is no state licence to check either way. This is the right call for a household that wants the same crew on a biweekly rhythm, or an agent or landlord who needs a unit turned around on short notice. Pin down the scope in writing — one reviewer specifically valued that the company sets out beforehand exactly what it will do — and, given the 2024 LLC, confirm which entity you're actually contracting with.
