Self-performing W-2 crews serving Denver — no subcontractors.
An approach validated by Harvard Business School and McKinsey research, built on Nobel laureate W. Arthur Lewis’s dual-sector labor theory.
A-One Janitorial LLC delivers professional post-construction cleaning services across the Denver metropolitan area, from the downtown core and Tech Center to Aurora, Lakewood, Centennial, and the broader Front Range. Denver is one of the fastest-growing construction markets in the Mountain West — producing Class A office towers, mixed-use developments, healthcare campuses, aerospace facilities, and industrial warehouses at a pace that demands a cleaning partner who can perform on schedule and to certificate-of-occupancy standards. A-One’s self-performing W-2 crews are deployed across the metro, ready to mobilize on your timeline.
What sets A-One apart is structural, not cosmetic. Harvard Business School and McKinsey research demonstrate that self-performing operations deliver 15–25% performance advantages over subcontractor-dependent firms. Our model applies Nobel laureate W. Arthur Lewis’s dual-sector labor theory to commercial cleaning services — a framework trusted by Fortune 500 clients across 30+ markets nationwide.
What Is Post-Construction Cleaning?
Post-construction cleaning is the systematic, professional cleaning of a facility following construction, renovation, or tenant improvement work — preparing it for owner delivery, certificate of occupancy, or immediate occupancy. It is not general maintenance cleaning. It requires trained crews, specialized equipment, and a structured phase approach aligned to the construction schedule.
Construction debris, drywall dust, adhesive residue, paint overspray, caulk film, and fine particulate contamination penetrate every surface of a newly built space. A-One’s post-construction cleaning protocols address each phase of project completion — from rough-in through final delivery — so that your property is presented at the standard your clients, tenants, and building inspectors expect.

Three-Phase Post-Construction Protocol
A-One structures post-construction cleaning across three coordinated phases aligned to your project schedule — minimizing trade conflicts and ensuring each phase is complete before the next begins:
- Phase 1 — Rough Clean: Deployed after framing and MEP rough-in. Scope includes debris removal, broom sweep of all floors, elimination of bulk waste, and preparation of the space for insulation and drywall installation.
- Phase 2 — Final Clean: Deployed after punch-out and before furniture installation. Full interior clean covering walls, ceilings, fixtures, flooring, windows, restrooms, kitchen areas, HVAC diffusers, and all horizontal surfaces throughout the facility.
- Phase 3 — Punch-List Clean: Deployed before owner delivery and certificate of occupancy. Detail cleaning of all punch-list items, final glass polish, floor finishing, and touch-up of any areas disturbed by late trade work.
