Post-Construction Cleaning Services

From Rough Clean to Final Inspection—OSHA Compliant & Schedule Ready.

The Three Phases of Construction Cleaning: Rough, Final, and Touch-Up

Post-construction cleaning is a phased process that prevents delays and rework. We align directly with your schedule:

  • Phase 1: Rough Clean (Debris & Prep): Occurs before flooring and paint. We remove heavy debris and scrape sub-floors so finishing trades can work safely.
  • Phase 2: Final Clean (Inspection-Ready): A deep clean once trades finish. We detail vents, glass, and floors to ensure the building passes the Certificate of Occupancy walkthrough.
  • Phase 3: Touch-Up Clean (Punch List): Occurs after final repairs. We remove reintroduced dust and smudges to ensure a pristine handover.

Job Site Safety: OSHA Compliance, PPE, and Silica Dust Control

On active sites, untrained crews are a liability. We operate as a safety-conscious trade partner: 

  • Silica Dust Control: We meet OSHA standards using industrial HEPA vacuums to capture hazardous silica at the source, protecting air quality and preventing fines. 
  • Mandatory PPE: Teams arrive equipped with hard hats, vests, and steel-toed boots—so your superintendent never has to stop work to correct us.
  • Hazard Awareness: Staff are trained on Job Hazard Analysis (JHA) to safely navigate scaffolding and machinery without disrupting trades.

Scheduling Flexibility: Working Around Trades and Tight Deadlines

Construction schedules rarely run exactly to plan. Costina adapts to your timeline, not the other way around:

  • Dynamic Rescheduling: We coordinate directly with your Site Superintendent and adjust around late trades, material delays, or last-minute changes.
  • Off-Hours & Night Work: Final cleans can be performed nights or weekends to avoid “stacking trades” and site congestion.
  • Surge Capacity: When timelines compress, we scale crews quickly to meet non-negotiable handover deadlines.

Protecting New Finishes: Safe Removal of Paint, Adhesives, and Overspray

Improper cleaning damages new finishes. We use material science to remove residue safely: 

  • “No-Scratch” Glass Protocol: We identify sensitive tempered glass and use non-abrasive pads to remove overspray, preventing permanent scratches from “fabricating debris.”
  • Adhesive Removal: We use specialized solvents to chemically dissolve silicone and glue bonds, protecting stainless steel and millwork from abrasion.
  • Floor Compliance: We protect warranties by using pH-neutral cleaners strictly matched to the manufacturer’s specifications for LVT, concrete, and stone.

Inspection-Ready Detailing: Preparing for the Certificate of Occupancy (CO)

Our goal is a signed Certificate of Occupancy. We prevent handover delays by cleaning to strict inspection standards:

  • Life Safety: We hand-wipe fire sprinklers and smoke detectors to ensure they are dust-free for the Fire Marshal inspection. 
  • Interior Cabinetry: We vacuum and wipe inside all millwork and drawers to remove hidden sawdust, ensuring owners see a finished product.
  • Pre-Inspection Audit: We perform a “White Glove” check to fix potential punch list items—like smudges and haze—before your final client walkthrough.

Post-Construction Cleaning vs. Standard Janitorial: Why Specialized Expertise Matters

Many contractors mistake post-construction cleaning for “stronger janitorial work.” In reality, they are distinct disciplines.

  • The Risk: Standard janitors maintain spaces; they lack the tools for silica control or adhesive removal. Using the wrong team risks scratched glass, damaged flooring, and failed inspections.
  • The Solution: We approach cleaning as a specialized trade, using industrial HEPA filtration and non-invasive scraping methods. 
  • The Result: Your project isn’t finished until the handover is flawless.
