Have you given much thought to the the crawl-space below your home? Most probably not. Unless an awful smell has appeared or there has been flooding, you may never have given it a second thought. Poor or non-existent underfloor ventilation can cause major issues for your home if not taken seriously – they can also become expensive.
Even though all homes SHOULD be built with subfloor ventilation, they are sometimes not. Or they may be built with venting… but garden beds and other structures may be built up against the home blocking any air flow beneath the property structure.
If there is not efficient air flow beneath a property, there is poor ventilation. Sometimes the air flow will need to be forced by a professional subfloor ventilation system.
When the ground is very moist, that moisture can be drawn into the air under your home. That damp air can then move up and draw into the porous building materials of your home. The real risk occurs when this damp air is not expelled from underneath your property because ventilation is poor or non existent. Mould and mildew can also begin to grow, and cause a dank musty smell.
Moisture underneath and within your building material can also attract termites as the timber that provides the foundation structure of your home begins to decay. Besides the damage that termites can cause, mould, mildew, rising damp and decaying timber can also result in health problems for the inhabitants of your home.
When your home is built the most basic of subfloor ventilation is put in through the form of air vents. Quite often this does not efficiently do the job, depending on your area, individual property and climate. Sometimes taking a look at each vent may reveal a reason why it is not working the way it should, a garden bed may be built up too high against it, the property may have inadequate drainage so rain is flooding into the subfloor, or perhaps the vents have just become blocked by debris or have been originally built in an incorrect position for airflow.
Even though all may be correct with your built in vents, it may not be enough to keep your home from being affected by damp. The overall best solution is an adequate subfloor ventilation system. But how does it work? Professional subfloor fans are positioned to draw out and externally exhaust damp air, using pumps and fans that are specifically designed exactly for the job at hand. These systems are customised for your property floor plan and the type of damp issues you face in your home. Subfloor ventilation systems are extremely quiet, run on a timer system and are generally inexpensive to run.
The Benefit of Termite Protection
Termites thrive in damp conditions, while feeding on timber. The risk of termites invading your home is increased where timbers have become damp and started to decay. An effective subfloor ventilation system ensures your home is less likely to be affected by termites.
The Benefit of Reduced Structural Damage
A damp subfloor can lead to structural damage. Moist air can start decay healthy timbers and attract termites.
Good ventilation helps to ensure the healthy dry timber that is the foundation of your home stays strong structurally sound without decay, rot and termite activity.
The Benefit of Limited Mould Growth
The main thing mould needs to grow is damp air. When there is mould growing in your subfloor it can cause a range of health issues which will usually trigger respiratory reactions in people which often are mistaken for allergies.
Efficient subfloor ventilation that reduces the air moisture under your home will fortunately limit mould growth.
The Benefit of Cost
There can be no price put on the cost of good health. Damp homes coupled with mould can cause a range of health issues.
The cost of termite treatments and potential structural repairs can be extremely expensive. Quite often insurance will not even cover termite damage. In comparison, the expense of good subfloor ventilation system is minimal.
