Construction & renovation cleanup
Post-construction cleaning services
The last trade on site decides whether the building shows like a finished space or a job site. 3Z's takes commercial build-outs, renovations, and tenant improvements across Columbus & Central Ohio from dusty and debris-covered to inspection-ready and move-in clean — on the general contractor's schedule.
How it's phased
Three cleans, one move-in-ready result
Construction cleanup isn't one pass. We phase it consistently to match how a job actually finishes — so trades keep working and the space still hits its turnover date.
Rough clean
Once the heavy work is done: debris and material removal, gross dust knock-down, and a clear path for the finishing trades to move efficiently.
Final detail clean
The big one. Fine construction dust removed from every surface, adhesives and stickers off, fixtures and glass detailed, floors prepped and finished — the space starts to look like the renderings.
Touch-up / white-glove
Right before hand-off or inspection: a final pass to clear settled dust, fingerprints, and punch-list marks so day one looks flawless.
What's included
Every surface a punch list touches
Scoped to your build during a walkthrough — a warehouse shell and a Class A office fit-out are very different jobs.
- Construction dust remediation — walls, ledges, ductwork exteriors, and the fine dust HVAC drives into everything
- Debris & material removal — offcuts, packaging, and staging areas cleared and coordinated for haul-off
- Adhesive, label & sticker removal — from windows, fixtures, appliances, and hardware
- Paint, compound & overspray spots — cleared from glass, floors, and finished surfaces
- Floor prep & finishing — strip, scrub, and finish VCT; extract carpet; polish concrete per the spec
- Windows, frames & sills — interior glass and reachable exterior glass cleaned inside and out
- Fixture & millwork detailing — lighting, cabinetry, casework, doors, and hardware wiped down
- Restroom & breakroom finishing — new fixtures cleaned, sealed, and made ready for use
Who we work with
Built for the people on the hook for the deadline
Post-construction cleaning is a schedule problem as much as a cleaning problem. We're used to working inside a construction environment — coordinating with the super, respecting other trades, and scaling the crew to hit a hard turnover date.
- General contractors closing out commercial projects
- Developers delivering new build-outs
- Property managers turning tenant improvements
- Business owners opening a renovated space

Common questions
Post-construction cleaning FAQs
What is post-construction cleaning?
It's the specialized cleanup that turns a finished construction site into a move-in-ready space — removing construction dust, debris, adhesives, stickers, and paint spots, then prepping and finishing floors so the space is ready for occupancy, inspection, or turnover. It's a different discipline from routine janitorial work, with different equipment and a different pace.
Do you work on the general contractor's schedule?
Yes — that's the whole point. Construction timelines move, so we schedule around your punch list and turnover date, scale the crew to hit the deadline, and phase the clean (rough, final, touch-up) to match trades finishing at different times.
Are you insured for construction sites?
Yes. We carry general liability insurance and can provide a certificate of insurance naming the general contractor or property owner before we mobilize. Our crews follow site safety and PPE requirements.
How is post-construction cleaning priced?
By the scope and condition of the build — square footage, how much dust and debris the trades leave, floor types and finishes required, glass count, and the timeline. We walk the site (or review plans for pre-bid) and give a written project price, not a vague per-foot guess.
Can you handle the final clean and ongoing janitorial after turnover?
Yes, and it's a common request. We deliver the move-in-ready final clean and then transition the building onto a recurring janitorial program, so one vendor is accountable from ribbon-cutting forward.
