Commercial Cleaning in Charleston, SC

Preferred Services Group delivers consistent, professional commercial cleaning to businesses across Charleston, Summerville, Goose Creek, Moncks Corner, and North Charleston. Our cleaning programs are tailored to your facility type, square footage, traffic patterns, and budget.

Whether you operate a corporate office, a medical building, a retail storefront, or a multi-tenant property, we build a recurring cleaning schedule that keeps your space healthy, presentable, and compliant.

Every program starts with a walkthrough rather than a phone estimate. We measure the areas that actually drive cost, count restrooms and entrances, look at floor types and the traffic they take, and ask about the compliance requirements specific to your building. A medical suite and an open-plan office of identical square footage are not the same job, and pricing them as though they were is how a cleaning contract ends up either overpriced or quietly under-serviced.

What you get back is a written scope of work: exactly what is cleaned, how often, and at what price. Daily tasks, weekly tasks, and periodic work such as floor care or window cleaning are listed separately so nothing is assumed on either side. If something falls outside the recurring scope, it is quoted as project work rather than absorbed silently or skipped.

Consistency comes from crew assignment, not from a checklist. You get a dedicated, background-checked crew who learn your layout, your access procedures, your supply closet and your expectations, supervised with photo reporting so you can see what was done without walking the building yourself. Most complaints about commercial cleaning are really complaints about staffing churn, and that is the part we design out from the start.

Scheduling flexes to the building. Offices and medical practices are usually best served in the evening or overnight, retail before opening, and buildings with restricted access or security procedures on whatever window their protocol allows. We work Monday to Saturday, 6:00 AM to 8:00 PM, and can add a day porter where a building needs attention while it is occupied rather than only after everybody leaves.
