How Much Does Commercial Post-Construction Cleaning Cost?

How phase pricing works

Most cleanups are quoted one phase at a time, because each happens at a different point in the build and takes a different amount of labor. Buying only a final clean is common, but when the rough clean is skipped, the final clean takes longer and costs more, since the crew is removing weeks of dust instead of days.

Dust load: the driver behind post-construction cleaning cost

Drywall sanding produces a fine powder that settles on every horizontal surface, inside light fixtures, on diffusers and in window tracks, and it keeps coming back as the HVAC system runs and moves it around. Jobs with demolition, concrete grinding or saw cutting leave even more. If the air handlers ran during construction without proper filtration, dust may be spread well beyond the work area. Exposed ceilings add high dusting from lifts, and residue such as labels, paint overspray, caulk, grout haze and concrete splatter all take hand work with the right tools.

Tenant improvement cleaning cost versus a new building

A tenant improvement suite inside an occupied building is small, but it often costs more per square foot. Crews must protect occupied corridors, book the freight elevator, follow building rules on hours and access, and sometimes clean overnight so neighbors are not disturbed. Finish level matters too: a suite with stone counters, glass walls and millwork needs more careful, slower work than one with standard finishes.

A ground-up building brings scale and different tasks. There is far more glass, often with construction residue on the outside, exterior hardscape to clean, and many trades still finishing punch items around the cleaning crew. Large areas lower the per-square-foot rate, but repeat trips caused by late trade work add it back.

What the price should and should not include

Disagreements on cleanup jobs usually come from inclusions, not rates. Agree in writing on which of these tasks are in the base price, which are priced as extras and which belong to the contractor or another trade before anyone starts.

• Usually included: dusting every surface, cleaning vent faces and fixture exteriors
• Usually included: interior glass and frames, label and residue removal
• Usually included: restrooms, cabinets inside and out, vacuuming and hard-floor cleaning
• Often extra: first finish coats on new resilient flooring
• Often extra: exterior glass above ground level, carpet extraction, pressure washing
• Often extra: high dusting of open ceilings and structure
• Usually excluded: hauling construction debris and dumpsters
• Usually excluded: duct cleaning and repair of finishes damaged by trades

Schedule compression and site conditions

A tight window between the last trade and the move-in date is one of the fastest ways to raise final clean pricing. A compressed schedule means a bigger crew or overtime, and trades still working on the punch list mean return trips. Active construction sites also require safety orientation, hard hats, vests and other protective equipment, and coordination with the superintendent.

Public projects carry one more check. California Labor Code section 1771 requires prevailing wages for workers on public works, and cleanup performed as part of a public works contract may be covered. Confirm with the public agency that owns the project or with the Department of Industrial Relations before comparing bids, because it changes labor cost substantially.

How EBS prices construction cleanup

Post-construction cleanup sits within EBS's specialty and project work, alongside floor care, carpet extraction, glass and pressure washing, so the finishing tasks a cleanup needs can be handled under one project. After walking the space with the contractor or property manager, EBS can price each phase on its own line. Once tenants move in, the building can transition into a recurring janitorial program without changing vendors.
