    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 underhouse ventilation system is installed inside your subfloor space to stop any excess moisture from entering your home.

    How Subfloor Ventilation Works

    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. The affordable solution is an economic, long-lasting under house ventilation system installed by Doctor Damp – trusted suppliers of underfloor ventilation in Sydney, Brisbane and beyond.

    Our consultants and 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. Whether you require sub floor ventilation in Sydney you can rest assured your under floor ventilation system will be customised to match your home and budget with a solution that works

    Subfloor Ventilation System Features

    The design of subfloor ventilation systems, including the choice and placement of underfloor ventilation fans, ducts, timers and exhaust vents, will result in:

    We only use quality, fit for purpose components including metal cased pumps with a five-year manufacturer’s warranty, acoustic sound insulated ducting, and special imported high moisture resistant (PVC fume control duct) PFC ducts. Better quality components result in superior performance and lower operating costs.

    Exclusive to Doctor Damp is the Silentflow pumps, Fanvent Pro V pumps, and smart pump models.

    Insulated ducting is used for improved acoustic performance, and special imported high moisture resistant (PVC fume control duct) PFC ducts are used to improve durability and longevity in damp under floor environments. Timers, mounted next to the sub-floor access hatch for easy service and maintenance, will be installed so that pumps run only during daylight hours. A five-year manufactures warranty applies to all Silentflow and Fanvent products for sub floor ventilation that we supply and install.
