There's no single right answer, but there is a simple way to decide: count the people and count the visitors. The more people use a space, and the more of those people are customers or clients, the more often it needs a professional clean.
A small office with a handful of staff and few visitors can usually stay in good shape with a weekly clean that covers restrooms, the break room, trash, and floors, plus a wipe-down of desks and high-touch surfaces.
Offices that see clients every day, like insurance agencies, real estate offices, and professional suites, usually do better with two or three cleans a week. Restrooms and entryways are where customers form an impression, and a weekly schedule leaves too many days in between.
Medical offices, busy storefronts, and anywhere food is prepared often need daily service, at least for restrooms, kitchens, and floors.
Whatever the frequency, ask for a written checklist. It's the easiest way to know what's being done on each visit, and to catch problems early. Mary's Black Label Cleaning Co. cleans offices across Monticello, Covington, Conyers, and the surrounding area, after hours or on Saturdays.
