Clean Spaces
We just finished construction and there is still dust everywhere, when is the building actually ready for employees or customers?
Final cleaning should happen after the dustiest work is complete and before people begin using the space normally.

Construction dust travels farther than people expect
Fine dust can settle on horizontal surfaces, inside cabinets, around door frames, on glass, and in rooms that were not the main work area. It can also resettle after the first cleanup if sanding, cutting, or installation continues elsewhere in the building.
Wait until the messy work is actually finished
If crews are still sanding, cutting, patching, or moving dusty materials through the space, a detailed final clean may need to wait. Otherwise, the cleaning team can finish a room only to have it coated again later.
Think like the person walking in on opening day
Look at the space from the perspective of an employee, customer, tenant, or inspector. Are floors clean, glass clear, restrooms ready, fixtures wiped, surfaces free of residue, and entrances presentable? Those are the details that make the building feel complete rather than still under construction.
Schedule the final clean before furniture and occupancy when possible
Cleaning is easier when access is open. If desks, displays, or furniture are installed first, dust can become trapped around them. The ideal timing is after construction is substantially complete but before the building becomes fully occupied.
