Builder’s dust in Sydney homes: Why specialised cleaning matters
If you’ve just finished a renovation, extension or new build in Sydney, you probably expected to move into a sparkling clean home. Instead, you’re dealing with a stubborn layer of fine dust that keeps reappearing on every surface, no matter how much you clean. This is extremely common — and it’s not your fault.
Builder’s dust is different from everyday household dust. It is finer, more abundant, and much harder to remove. At 1800 CLEANER we specialise in tackling this exact problem. Our system removes up to 97% of fine particle dust down to 30 microns in a single visit, eliminating the Dust-Drop Effect that leaves most post-renovation homes dusty for months or even years.
Why builder’s dust is so difficult to remove
Construction work creates enormous amounts of extremely fine dust. Cutting tiles, sanding floors, plastering walls and painting all release microscopic particles — many smaller than 30 microns. This dust is so light that it stays suspended in the air for days and works its way into every crack, vent, cupboard and soft surface.
Unlike normal household dust, builder’s dust often contains:
- Respirable crystalline silica (from concrete and stone)
- Gypsum and plaster particles
- Paint overspray and chemical residues
- Fibreglass and insulation fibres
These particles are not only difficult to see — they are dangerous to breathe and notoriously hard to capture with standard cleaning methods. Ordinary vacuums and cloths simply stir them up, charging the particles with static electricity so they float around for up to five days before resettling. This is the Dust-Drop Effect, and it explains why many new or renovated homes feel dusty for a very long time.
Why most cleaners fail at builder’s dust
Most cleaning companies treat a builder’s clean like a regular house clean. They wipe surfaces and use standard equipment that cannot trap the finest particles. As a result, a large portion of the construction dust remains airborne or escapes back into the home. Homeowners often end up living with this dust for months, dealing with ongoing respiratory irritation and constant re-cleaning.
Specialist builder’s cleaning requires more than enthusiasm — it demands the right equipment and proven technique.
How 1800 CLEANER removes builder’s dust properly
We approach builder’s cleans with the same scientific precision we use for all our services. Our system is specifically designed to handle the heavy, fine dust created by renovations and new builds.
Here’s what makes our process different:
- HEPA filtration captures particles down to 0.3 microns — far smaller than standard vacuums can handle.
- Ionisers charge the fine construction dust so it clumps together and gets trapped more effectively.
- Anti-bacterial filters remove silica, mould spores and chemical residues while releasing negative ions that leave the air feeling fresh.
- Specialised technique minimises disturbance and targets hidden areas under floors, in vents, inside cupboards and behind appliances.
We guarantee to remove up to 97% of fine particle dust down to 30 microns in one visit. This single thorough clean eliminates the Dust-Drop Effect so your home stays noticeably cleaner afterwards.
Real results from Sydney renovations
Don’t just take our word for it. Here’s what some of our clients say after a builder’s clean:
For anyone suffering from asthma or allergies I highly recommend the 21-point clean. I have an asthmatic son who had instant relief in our home after the clean. I will be budgeting in the maintenance service after seeing such a dramatic change in his well-being. Michael and Michelle were on time, friendly, reliable and paid attention to detail. Communication was five stars when making the booking, answering questions and further communications after the appointment. — Cindy P, Vaucluse
Michael and his team did an amazing job with our builders clean. The quoting and booking process was very efficient and the staff so friendly. We were so impressed with the standard of the clean. On top of the normal house clean to remove all the builders dust and generally clean we asked them (at the last minute) to clean our attic which had been left in a huge mess after our renovation. The team did the most incredible job moving and organising all our belongings and cleaning fine dust from a really tricky space. We would highly recommend!! Thanks again to Michael and the whole team. — Tanzim – Coogee
Michael and his team were very professional and considerate in their approach to cleaning my house. I felt very comfortable leaving the house in their hands for 8 hours… I returned to a house full of light and smelling so fresh, sparkling windows. This is the best cleaner I’ve had! I intend to rebook for future 21-Point cleans. I will definitely recommend 1800 CLEANER to my friends and work colleagues. Thank you. — Geraldine, East Balmain

A proper builder’s clean does more than make your home look good on handover. It protects your family’s health, reduces long-term cleaning effort, and prevents expensive recurring dust problems. Once the heavy construction dust is removed, your regular maintenance cleans become much easier and more effective.
