New homes in Tarneit and Riverbend often leave behind fine plaster, sawdust and insulation particles that settle deep in supply and return runs after builders finish. These materials are lighter than typical household dust and travel easily once the system starts running during Werribee’s warm summers. Standard household filters rarely catch everything, so the particles continue circulating and can reduce airflow over time.
Ductwork in City of Wyndham subdivisions is frequently installed before final plastering and painting, meaning joints and boots can contain chunks of compound that later break loose. Accessing these sections requires removing grilles and using brushes sized for the 150–200 mm flexible runs common in local project homes. Skipping the return side or the main trunk near the furnace leaves the bulk of the contamination untouched.
Homeowners in Wyndham Vale sometimes notice a persistent white film on surfaces weeks after moving in. This is usually construction dust being pushed through the vents rather than a filter issue. A proper post-construction clean uses negative-air machines to contain the debris and prevent it from entering living spaces during the job.
Technician insight
In Werribee the thing that catches most people out with post construction duct cleaning is the fine plaster dust that settles in the long horizontal runs of project homes in Tarneit and Riverbend. Warm summer temperatures mean the system runs longer, pushing that dust into rooms before the owners even notice the white film on surfaces.
New Build In Riverbend
A family moving into a recently completed house near the Werribee Open Range Zoo reported white dust on every surface after the first week of cooling use. Inspection showed thick plaster residue throughout the main trunk and branches installed before final painting. We isolated the unit, agitated and extracted the debris, then confirmed clear airflow at every grille. The homeowners reported no further dust after the clean.
How it works
- 1
Site Assessment
Inspect every accessible supply and return run, note grille locations and measure trunk lines in the new build.
- 2
Isolation And Containment
Seal off the HVAC unit and living areas with plastic sheeting to keep construction dust from spreading during cleaning.
- 3
Agitation And Extraction
Use rotary brushes and compressed air to dislodge debris while the vacuum system pulls it out through the main trunk.
- 4
Final Filter Check
Replace or clean the system filter and verify airflow at multiple points before handing the home back to the owner.
Pricing
Cost depends on the number of runs, length of trunk line and how much plaster dust remains after handover.
