Castle Keepers built its name on green cleaning: crews work with engineered water and PerfectCLEAN microfiber cloths, a method that lifts dirt and germs with little more than tap water instead of a cart of harsh chemicals. It is the Greenville branch of a privately owned South Carolina company that has cleaned homes since 1994, and the people who show up are trained employees on staff, not contractors booked under the brand name.
The work runs from recurring and one-time house cleaning to office cleaning, reaching across Greenville out to Taylors, Greer, Simpsonville, Mauldin, Easley, Powdersville, Travelers Rest, and Fountain Inn. Reviewers tend to name the specific cleaner assigned to their home and mention the same team coming back visit after visit, which is the harder thing for a cleaning service to get consistently right.
