Zak and Ryan did a amazing job. Even with the obstacles of a double story home with a internal switch board they persevered in the heat and got the job done. Thanks guys we realy appreciate your work and polite attitude.

We assess subfloor moisture, access, existing vents, airflow paths and drainage before deciding whether mechanical ventilation is appropriate. The quote covers the agreed fans, ducting, controls, dedicated supply, installation and commissioning. For extraction, cross-flow design, humidistat controls and installation details, see the full detail on underfloor ventilation.
At around 1830 people per square kilometre, Croydon South properties have enough clearance around them that vents work if they are not blocked. Croydon South is around 130 metres. Moderate conditions with predictable damp on the high side.
Croydon South is 29 kilometres from town. We will tell you plainly if your floor is a slab and this is not your issue. Croydon South is in Maroondah. Subfloor ventilation needs no council permit in the ordinary case. It needs licensed work and a Certificate of Electrical Safety.

Background that shapes the job: Croydon South Post Office opened on 1 February 1961 as the suburb was developed.

No. The run from Boronia to Croydon South is about 5.2 kilometres north, which is well inside our regular patch, so there is nothing added for travel.
The neighbouring suburbs we work are Bayswater North, Croydon, Kilsyth and Ringwood East. A Croydon South booking often slots into a run we already have through them.
The council is Maroondah and the postcode is 3136. Ordinary work here needs no council permit, only licensed work and a safety certificate.
It fixes the subfloor moisture that feeds it. If there's an active leak or a drainage problem, that has to be sorted too, ventilation manages humidity, it doesn't stop water coming in.
Tell us about the damp, odour or floor symptoms you have noticed. We’ll assess access, airflow and moisture, then provide a clear ventilation scope where appropriate. Book an assessment or call our Boronia crew to discuss the work.
