Day Porters & Overnight Janitorial Crews
Janitorial service is the recurring contract that resets your building: restrooms cleaned and restocked, floors vacuumed and mopped, trash and recycling removed, high-touch surfaces disinfected, break rooms and common areas returned to standard. It runs on a fixed schedule, usually after hours, and it is the foundation every other cleaning service sits on top of.
When a single nightly clean is not enough, our porter services keep your facility looking sharp throughout the business day. We provide uniformed staff dedicated to your building, restocking, monitoring restrooms, wiping down high-touch areas, and addressing spills the moment they happen.
Pair daytime porters with overnight janitorial crews for around-the-clock cleanliness in office buildings, medical complexes, condo clubhouses, and high-traffic public spaces.
How often you need service is driven by headcount and traffic, not by square footage alone. A 6,000 square foot office with 12 people can run comfortably on three nights a week. The same footprint with 60 people, a busy reception area and two shared restrooms usually needs nightly service, because restrooms and break rooms are what generate complaints, and they degrade on a people schedule rather than a floor-area one.
Every program is quoted from a walkthrough and delivered against a written scope of work, so both sides know exactly which tasks are nightly, which are weekly, and which are periodic. Floor care, carpet extraction and window cleaning are quoted separately as project work rather than folded in vaguely, which keeps your monthly cost predictable and stops those tasks from quietly never happening.
The part clients notice most is staffing. You get a dedicated, background-checked crew who learn your building, your access procedures and your supply closet, with supervision and photo reporting so you can verify the work without walking the floors yourself. Most complaints about a janitorial contract are really complaints about crew churn, and that is a scheduling decision we make deliberately rather than a lottery.
We run janitorial programs across Charleston, North Charleston, Mount Pleasant, Summerville, Goose Creek, Moncks Corner, Hanahan, Ladson, West Ashley and Daniel Island, Monday to Saturday, 6:00 AM to 8:00 PM. Multi-location operators get one point of contact and consolidated billing rather than a different crew leader at every site.
