How Often Should a Commercial Office Be Professionally Cleaned?

The most common question we hear from Lexington business owners setting up a cleaning contract for the first time isn't "how much" — it's "how often." The honest answer is that it depends more on foot traffic and industry than on square footage alone.

Daily or nightly cleaning

Offices with client-facing lobbies, medical and dental practices, restaurants, and any space with more than 20-30 people through the door each day generally need cleaning every night or every business day. Restrooms, break rooms, and high-touch surfaces accumulate grime fast enough that skipping even one day becomes noticeable.

Two to three times a week

Small professional offices — law firms, insurance agencies, small tech teams — with a handful of staff and few or no walk-in visitors often do well on a two- or three-day-a-week schedule. Trash, vacuuming, and restroom service still happen regularly, just not nightly.

Weekly service

Very small offices, or spaces where staff already handle daily tidying themselves, can sometimes stretch to a weekly deep clean covering floors, restrooms, and surfaces that don't get attention day to day.

What actually drives the decision

• How many people (staff plus visitors) use the space daily
• Whether clients or the public walk through
• Industry-specific requirements (medical, food service)
• Carpet vs. hard flooring, and how much outdoor debris gets tracked in
• Budget — frequency is usually the first lever to adjust, not the scope of work

If you're not sure where your office falls, the safest starting point is to set an initial schedule, watch how the space looks between visits for a month, and adjust frequency up or down from there. Most Lexington janitorial contracts allow that kind of adjustment without a long lock-in.
