After the last nail is hammered and the final coat of paint is dry, your building still isn’t ready to shine. Dust, debris, paint splatters, and leftover materials cover every corner. That’s when post-construction cleaning comes in — the final and most important step before the property becomes move-in ready.
But how much does construction cleaning cost? What should you expect, and how can you plan your budget smartly?
In this guide, we’ll explain everything about post-construction cleaning costs — from price ranges and cost factors to smart budgeting tips. Whether you’re a builder, property developer, homeowner, or real-estate agent, this guide will help you make informed decisions and avoid unnecessary expenses.
What Is Post-Construction Cleaning?
Post-construction cleaning (also called after-build cleaning or builders cleaning) is the professional cleaning process performed after construction or renovation work is complete. It removes the dust, debris, and marks left behind by builders, painters, and tradespeople.
This isn’t regular house cleaning. It’s a detailed, heavy-duty clean designed to make a new or renovated space spotless, safe, and ready for use.
A typical post-construction cleaning includes:
- Removing construction dust from floors, walls, and ceilings
- Cleaning paint or plaster splashes
- Washing and polishing windows and glass
- Vacuuming carpets and mopping floors
- Deep cleaning kitchens and bathrooms
- Wiping switches, doors, frames, vents, and fittings
In short — it transforms a construction zone into a fresh, clean property that’s ready for inspection or move-in.
Why You Should Budget for Construction Cleaning
Many people forget to include cleaning in their project budget. As a result, they end up rushing or overspending at the last minute.
Here’s why proper budgeting matters:
- Smooth handover: A clean site ensures builders or developers can hand over on time.
- Better presentation: Clean properties attract buyers and tenants faster.
- Compliance and safety: Dust and debris can be health hazards; professional cleaning ensures a safe environment.
- Cost control: Planning early helps you compare quotes and avoid surprise expenses later.
Think of cleaning as the final polish your project deserves — not an optional extra.
Average Post-Construction Cleaning Costs in Australia
Prices vary depending on the size, type, and condition of the property, but here’s a general guide to average construction cleaning prices in Australia (AUD):
| Property Type | Average Cost | What’s Included |
| Small Apartment or Unit | $250 – $400 | Light debris removal, vacuuming, surface wipe-down |
| Medium Home (3–4 Bedrooms) | $450 – $800 | Full interior clean, window cleaning, kitchen & bathroom detail |
| Large or Luxury Home | $800 – $1,500+ | Multi-room deep cleaning, window polish, floors & fixtures |
| Commercial / Office Site | $1,000 – $3,000+ | Heavy-duty cleaning, floor buffing, external washdown |
Tip: Always ask for a detailed, written quote listing inclusions, equipment used, and any optional extras like high-pressure washing or floor polishing.
Factors That Affect Construction Cleaning Cost
Every project is different. Several key elements influence your total price:
1. Property Size
The larger the property, the more rooms, floors, and surfaces need attention — increasing both labour time and cost.
2. Type of Property
Houses, apartments, and commercial sites all have different cleaning requirements.
For example, an office may need machine floor polishing, while a home might require window detailing and kitchen sanitising.
3. Level of Dirt and Debris
Heavy post-renovation mess — such as dried plaster, adhesive, or concrete dust — takes longer to clean than a light tidy-up.
4. Number of Cleaning Phases
Most professional cleaners perform up to three stages:
- Initial Clean: Removal of rubble, dust, and rubbish
- Detail Clean: Deep cleaning of fixtures, fittings, and surfaces
- Final Clean: Touch-ups before client inspection or handover
Each stage adds to total cost, but ensures flawless results.
5. Access and Location
Hard-to-reach areas, multi-storey buildings, or sites with limited parking often cost more because they require extra time or special equipment.
6. Special Requests
Extras like window tracks, tile grout cleaning, carpet steam cleaning, or pressure washing can increase the total bill. These tasks need extra tools and skilled staff.

How to Plan Your Cleaning Budget
1: Estimate Early
Include cleaning in your initial project budget.
For most builds, allocate 0.5% to 1% of the total construction cost for cleaning.
Example:
If your build costs $400,000 → set aside $2,000–$4,000 for post-construction cleaning.
2: Request Detailed Quotes
Ask at least three cleaning companies for quotes.
Request written breakdowns of:
- Included services
- Labour hours
- Equipment use
- Disposal fees
3: Schedule the Cleaning Wisely
Plan cleaning after all construction and painting are finished — ideally right before handover.
If you schedule too early, you may have to pay for repeat cleaning.
4: Choose Experienced Professionals
A professional team knows how to protect new surfaces, handle delicate finishes, and use safe, non-toxic products.
Example Cost Breakdown (Medium 3-Bedroom Home)
| Task | Hours | Cost (AUD) |
| Rough Clean | 3 | $180 |
| Detail Clean | 5 | $350 |
| Window Cleaning | 3 | $160 |
| Bathroom & Kitchen Detail | 2 | $140 |
| Floor Polishing | 2 | $120 |
| Rubbish Removal | – | $70 |
| Total Estimate | – | $1,020 |
These figures are averages — actual prices vary based on your region, company, and project size.
How to Save Money Without Cutting Quality
- Do light prep work yourself – Remove big debris before the cleaning team arrives.
- Plan once, not twice – Schedule cleaning after all trades finish to avoid rework.
- Bundle services – Combine window, carpet, and floor cleaning for a better rate.
- Keep areas sealed – Use plastic sheets and dust barriers during construction.
- Ask for package deals – Some companies offer discounts for repeat or referral work.
DIY vs Professional Post-Construction Cleaning
| Feature | DIY Cleaning | Professional Cleaning |
| Equipment | Household tools | Commercial-grade machines |
| Speed | Slow and exhausting | Quick and efficient |
| Finish | Incomplete or streaky | Spotless and detailed |
| Safety | Exposure to fine dust | Trained, insured, and safe |
| Cost | Low upfront | Higher, but worth it |
Bottom Line:
DIY is fine for small jobs. For larger projects or commercial sites, hiring professionals saves time, effort, and ensures a perfect finish.
Common Post-Construction Cleaning Cost Mistakes
Avoid these pitfalls when planning your cleaning budget:
- Forgetting to include cleaning in project cost
- Hiring cleaners without checking insurance or experience
- Accepting vague or per-hour quotes without itemisation
- Scheduling cleaning before trades are finished
- Ignoring surfaces that need special care (like marble or glass)
Always review the cleaning scope in writing to avoid disputes or hidden fees.
How Professional Cleaning Adds Value
Post-construction cleaning does more than just make things look good:
- Creates a great first impression – Especially for property sales or rentals
- Prevents damage – Removes abrasive dust before it scratches surfaces
- Improves safety – Eliminates nails, glass, or fine dust that cause accidents
- Saves time – Your team or client can move in faster
- Protects your investment – Clean properties maintain their finish longer
Think of it as the final stage of craftsmanship — where your hard work truly shines.
Eco-Friendly Cleaning Options
Many modern companies now use green cleaning products that are biodegradable, non-toxic, and safe for the environment.
These not only protect your newly finished surfaces but also keep indoor air quality clean and fresh.
When requesting a quote, ask if they use:
- Water-based solutions
- HEPA-filtered vacuums
- Microfiber mops instead of chemical sprays
It’s better for your health, your workers, and the planet.
When to Hire Budget Friendly Professional Cleaners
You should book a post-construction cleaning service when:
- Construction is 100% complete (no more painting or drilling)
- The property is dusty, and detailed cleaning is required
- You need the space ready for staging, handover, or inspection
- You want to meet safety or presentation standards
It’s best to book at least 1–2 weeks in advance to ensure availability.
