SUB FLOOR AND INTERNAL VENTILATION ISSUES? MUSTY ODOURS? CALL DAMPCO ON 1300 382 826 NOW

Ventilation is the single most important factor when it comes to condensation and mould. Increasing ventilation will remove moisture from the internal atmosphere and eliminate condensation.

If the moisture intrusion has been identified as being caused by a lack of ventilation - and this is often the case - then adding ventilation will obviously assist the building to relieve itself of a build up of moisture. It is however, very important to understand, that if moisture has established itself in a building, it is often necessary to dry the building prior to establishing or increasing ventilation in the property. A poorly ventilated subfloor is often the cause of rising damp and other moisture issues.

NATURAL VENTILATION

Increasing natural ventilation will sometimes enable a building to breathe enough to reverse an excessive moisture atmosphere - after drying. In the subfloor, cross flow ventilation is vital and modern building regulations have strict requirements as to the number of passive vents required per lineal metre of wall space. Older properties tend to never have enough passive vents and often even those that are installed are inadequate due to the low level of many older houses. Adding passive vents is a first step to reducing subfloor moisture - and Dampco can install passive vents (subject to access) from as little as $220 per vent.

FORCED AIR VENTILATION

If moisture is an ongoing problem the best method of permanently relieving the property of a build up of moisture - either in the subfloor or roof cavity - is to add a mechanical ( forced air) ventilation system. These are typically switched via a 24 hour timer or a hygrometer (humidity thermostat) and are operated via 240V. Because they are powered (not solar) and switched, these systems put the home or building owner in complete control of the indoor environment and they are therefore able to manipulate the indoor environment to permanently keep the property moisture free.

Again, it must be stressed that drying the property prior to installing a forced air ventilation system is generally required. Call or email us for more details and to arrange for a free inspection and 12 report.
