Commercial Post-Construction Cleaning
Post-construction cleaning for commercial builds, tenant improvements and remodels. Ascent Cleaning cleans up after the builders, from rough cleans while work is under way to the final clean before move-in.
Rough, final, and touch-up cleaning
Rough and progress cleans keep the site workable while the project continues. Final and pre-opening cleans ready finished spaces, and touch-ups catch areas reworked by late trades.
Floors, windows, and interior surfaces
We clean new floors, interior glass and window frames, fixtures and restrooms, using the right method for each new surface. Our cleaning also covers the entrances and hardscape you choose.
Cleaning after the trades
We work as the construction team releases each area, so cleaning keeps pace with the project as spaces are completed.
From turnover to everyday care
Once the final clean is done, the space is ready for its new occupants. The space can then move straight into recurring janitorial service, so the new space stays as clean as it was on opening day.
New floors can be maintained from the start with commercial floor care.
What each stage of a post-construction clean covers
Rough cleaning happens while trades are still on site. It clears debris, packaging and loose dust from areas the builder has released, so the next trade starts on a clean floor. Progress cleaning repeats that pass as more spaces open up.
The final clean is the detailed one: dust removed from ledges, frames and reachable fixtures, glass and window frames cleaned, restrooms and kitchenettes made ready to use, and floors cleaned to suit their new material. A touch-up pass afterward handles areas reworked by punch-list trades.
Tenant improvements and remodels in occupied buildings
Not every project is a new building. Tenant improvements in San Francisco office towers, refreshed suites in Pleasanton business parks and remodeled storefronts in Roseville retail centers all happen next to people who are still working. Keeping dust out of the occupied space matters as much as the clean inside the work area.
Cleaning is timed with the construction team’s schedule, so finished areas are released, cleaned and handed back in order. Adjoining corridors and lobbies used by other tenants are cleaned on the same visits, so construction dust doesn’t spread into occupied space.
Planning the clean before the project ends
Bring cleaning into the schedule early. Tell us the square footage, the project type, which stages you want covered, the target opening or move-in date, and the flooring being installed. New resilient floors and freshly poured concrete each change how the final clean is planned. Your general contractor or property manager gets our certificate of insurance before the crew arrives on site.
Multi-site rollouts, such as a retailer fitting out stores in several cities, run every location’s final clean under one plan, timed to each store’s opening date. Once a store opens, it moves onto the same recurring schedule as the rest of the group.
What happens on a final-clean day
Final cleaning works top to bottom: high reachable surfaces and fixtures first, then glass, then restrooms and kitchenettes, and floors last so settled dust comes up in the final pass. Rooms are finished in order, so the construction team can walk each one as it is completed and flag anything for touch-up.
Post-construction cleaning costs by the square foot
Post-construction cleaning is a one-time job priced per square foot across all phases. Most commercial projects land between $0.29 and $0.70 a square foot for rough, final and touch-up cleaning together, going by 2026 published market data, with light remodels at the low end and dusty new builds with lots of glass and fixtures at the top or beyond it.
Consider a 10,000-square-foot tenant improvement in Campbell with new carpet, a kitchen, two restrooms and a glass storefront. Priced at $0.42 for all three phases, the cleaning comes to $4,200. If the builder only needs the final clean and a touch-up before the tenant moves in, the per-foot rate drops, since the rough pass and progress cleans fall away.
Dust load is the main driver: drywall sanding, flooring work and ceiling work leave far more residue than a paint-and-carpet refresh. The amount of glass, ledges, light fixtures and cabinetry, how many phases you need, debris and packaging left behind, and deadlines tied to an opening date all push the price. Rush or short-notice scheduling costs more, and so does night or weekend work around other trades. A walkthrough with you or your builder sets the phases and timing, and we price each phase in the quote so the total is clear before work starts.
A few useful answers
Common questions.
Can cleaning follow each phase of a renovation?
Yes. Rough and progress cleaning follow the project, with final and touch-up cleaning once areas are complete.
How soon after construction ends can the final clean happen?
As soon as the construction team releases the space. Final cleaning is scheduled around your opening or move-in date, with a touch-up visit after any late trade work.
Can post-construction cleaning cover a tenant improvement in an occupied building?
Yes. Work areas are cleaned as they are released, and adjoining shared areas are cleaned on the same visits.
Which surfaces need special care after construction?
New floors, glass and fixtures. We check each new surface and the residue on it before choosing a cleaning method.
