The time it takes to clean an office building depends on several factors, including the size of the building, the level of cleaning required, and the number of cleaners working.

Here’s a general guide…

Small Office (1,000 to 3,000 sq ft)

• Time – Typically 1 to 3 hours for a standard cleaning (dusting, vacuuming, emptying trash, cleaning bathrooms).

Medium Office (3,000 to 10,000 sq ft)

• Time – About 3 to 6 hours for a thorough cleaning, which may include additional tasks like window cleaning, restocking supplies, and deep cleaning high-traffic areas.

Large Office (10,000+ sq ft)

• Time – 6 to 10 hours or more, depending on the complexity of the cleaning and the number of people working.

Factors That Affect Cleaning Time

• Cleaning Frequency – Daily cleaning will usually take less time than weekly or monthly deep cleaning.
• Tasks – Specialty services like carpet cleaning, window washing, or floor waxing can add significant time.

Conclusion

• Small Office – 1 to 3 hours.
• Medium Office – 3 to 6 hours.
• Large Office – 6 to 10+ hours.

The time will vary based on office size, cleaning scope, and the number of staff involved.
