Our Commercial Cleaning Process

1

Site Assessment and Customised Plan

We begin with a full on-site inspection to assess the scope of work and provide a detailed, itemised quote. Whether your space requires deep cleaning or targeted touch-ups, we’ll customise our services to meet your exact needs.

2

Cleaning Execution

Our experienced cleaners work with high-grade equipment and eco-friendly products to ensure every area is thoroughly cleaned and sanitised. From windows and floors to hard-to-reach corners, we don’t miss a spot.

3

Final Inspection and Touch-Ups

After the main cleaning is complete, we conduct a final walkthrough with your team to ensure every requirement has been met. If needed, we make final touch-ups so your property is in perfect condition for handover or opening.
