Blogs on Post-Renovation Cleaning

You’ve just completed a renovation, extension or new build in Sydney. The tradies have left, the paint has dried, and you expect to walk into a fresh, clean home. Instead, fine dust covers every surface, lingers in the air, and keeps returning no matter how often you clean. This frustrating situation is extremely common — and it happens for a very specific reason.

Post-renovation cleaning differs significantly from regular house cleaning. Construction dust is extremely fine, highly invasive, and much harder to remove. At 1800 CLEANER we specialise in proper builder’s and post-renovation cleaning. Our advanced 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 renovated homes dusty for months.

This practical guide shows why standard cleaners fall short and exactly how we deliver a truly clean, healthy home.

Why construction dust creates such a big problem

Renovations generate massive volumes of microscopic dust. Cutting tiles, sanding floors, plastering walls and painting release particles far smaller and more abundant than everyday household dust. Many measure under 30 microns — roughly 1/30th the width of a human hair.

Moreover, this dust spreads everywhere. It infiltrates air vents, settles behind cupboards, works under floors and embeds itself deep into carpets and upholstery. In Sydney’s humid coastal climate the situation worsens quickly. Moisture keeps particles airborne longer, and mould can start growing if the dust remains.

Construction 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 not only look bad — they irritate lungs, trigger allergies and asthma, and pose longer-term health risks when left circulating.

Why standard cleaners and normal methods fail

Most cleaning companies treat a post-renovation clean like a regular house clean. They wipe visible surfaces, use standard vacuums and mops, and finish the job. Unfortunately, these approaches cannot handle fine construction dust effectively.

Ordinary vacuums only capture larger particles. The finest dust escapes through the exhaust and blows straight back into the home. Wiping and dusting simply stirs up more particles and charges them with static electricity. As a result, the dust becomes airborne for up to five days before resettling — this is the Dust-Drop Effect.

Consequently, many homeowners live with construction dust for months. They constantly re-clean and breathe in irritants, which is exactly why specialist post-renovation cleaning matters.

How 1800 CLEANER removes construction dust properly

We approach every builder’s and post-renovation clean with scientific precision. Our system actively targets and captures the heavy, fine dust created by renovations.

Here’s exactly what our process includes:

• We thoroughly dust and clean ceilings, ledges, walls, blinds, vents, fans and windowsills using techniques that trap dust instead of spreading it.
• Our team performs deep HEPA vacuuming on every floor, carpet, stair and area under furniture (up to 45 kg).
• We clean hard floors and all visible surfaces with professional microfibre systems that lock in particles.
• While the team works, our HEPA + ioniser + anti-bacterial unit runs continuously and actively pulls fine dust from the air.
• We finish by flooding the home with negative ions, creating that fresh “mountain air” feeling and helping capture any remaining particles.

Because these technologies and techniques work together, we remove up to 97% of fine particle dust down to 30 microns in one visit. We therefore eliminate the Dust-Drop Effect so your home stays noticeably cleaner long after we leave.

Real results from Sydney renovations

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

The long-term benefits of specialist post-renovation cleaning

A proper builder’s clean does far more than create a good first impression. It protects your family’s respiratory health, reduces long-term cleaning effort, and prevents months of ongoing dust problems. Once we remove the heavy construction dust, your regular maintenance cleans become faster, easier and more effective.

Frequently Asked Questions

Q: When is the best time to book a post-renovation clean? A: Book as soon as the builders finish and all major work is complete. The sooner we remove the fine dust, the better.

Q: Can normal cleaners handle builder’s dust? A: Most cannot. Standard equipment and methods simply do not cope with the volume and fineness of construction dust.

Q: How long does a builder’s clean take? A: A typical post-renovation clean takes a full day (6–8 hours), depending on the size of the home and scope of work.

Q: Will this help with asthma or allergies after renovation? A: Yes. Removing construction dust and silica particles often brings significant respiratory relief.

Q: Do you offer ongoing maintenance after the builder’s clean? A: Absolutely. We recommend a 21-Point Spring Clean followed by regular maintenance to keep your home dust-free long term.
