What is Sub Floor Ventilation?

Subfloor ventilation, also known as under floor ventilation and under house ventilation, is a type of ventilation system that removes damp air from inside your household and transfers dry, fresh air to areas beneath your floor. An under house ventilation system is installed inside your subfloor space to stop any excess moisture from entering your home. A subfloor (or underfloor) is liable to get damp & musty if left unchecked. Without sub floor ventilation, you risk:

Don’t risk your greatest investment becoming an expensive repair job—no home subfloor should be a problem.

How Subfloor Ventilation Works

The purpose of sub-floor ventilation is to replace the moist air with fresh dryer air. The simplest method used to achieve this is to install a number of vents in the wall around the building and rely on natural ventilation (air movement) to take care of the underfloor ventilation.

Excessive sub-floor moisture can cause rising damp, wood rot, problem odours and pest infestation. If untreated, sub-floor moisture may result in the growth of moulds and mildew, causing serious health issues.

Our technicians know how to install sub floor ventilation systems and how to remove ground moisture from underneath raised floors. Duct openings will be positioned at problem locations so that damp air may be drawn off and externally exhausted. 

If you require sub floor ventilation services near Coffs Harbour, you can rest assured your under floor ventilation system will be customised to match your home and budget with a solution that works

Myles from Thunder Electrical was fantastic. I had a hot water issue at my holiday apartment late on a Friday afternoon, and he knew exactly what the problem was straight away. He provided a quote over the phone and had everything fixed within 1.5 hours of my initial call. Super efficient, reliable, and easy to deal with. Can’t recommend him highly enough—will definitely use Thunder Electrical again!

Thunder Electrical are amazing at what they do. Easy and convenient to book in jobs with and upfront and fair with their pricing. Work with you to get what you need and don't cut corners. Very good with their communication regarding what needs to happen and what is involved in getting the job done. Were great at fixing up some old dodgy electrical work that had been completed previously. Will be getting them back and highly recommend!

These guys give tradies a GOOD name! Brilliant service. Called in the morning with a hot water system problem, Myles was here in the afternoon (even calling to let me know he would be a bit later the originally expected), assessed the fault, fixed it for us then and there! Polite, professional and did what he said he would when he said he would. So refreshing - as what the hot shower later that evening! Highly recommend - first time we've used Thunder - won't be the last.
