Rising Damp – Solutions To Eradicate Damp From Your Home

Many homes suffer from dampness rising up thru the floor. Not only does this lead to odour and mould, it can actually undermine the structural integrity of your property and also provide an ideal environment for termite growth.

A Typical Solution

A timer controlled, mechanical ducted subfloor ventilation system will provide air flow and air exchange to remove that damp layer of air and keep your subfloor dry.  We need to consider geography (slope), geology (sandstone, clay) and also existing drainage in developing a solution.


A quality system for an averaged sized home should be around $2500 supplied, installed, including GST and 5 years warranty.


Sure.  Talk to us about supplying a kit.

The quality of indoor air that you breathe can spell doom to your health if it is polluted. There are many components in the home that could pollute your indoor air. Damp in the home will affect your health – you might develop asthma, allergies and other respiratory infections. Young children and the elderly are particularly vulnerable to infections resulting from a damp home. This is why Mouldbuster is committed to providing solutions to the rising damp in homes.

A damp home encourages the growth of mould, which produces substances that could trigger allergic reactions. Spores from mould might cause you to sneeze and you might even develop a skin rash or suffer from itchy eyes or a runny nose. Moreover, damp in the home encourages the spread of bacteria and attracts pests such as mice and cockroaches.

The home becomes damp when there is excess moisture in the air that has nowhere to escape. Damp conditions in the home could be caused by:

  • Rising damp in the sub floor.
  • Building materials in a new home that have not properly dried.
  • Leaking water pipe.
  • Rain trickling into the home from window frames and damaged roofs.
  • Lack of proper ventilation in the home.

How To Get Rid Of Rising Damp From Your Home

When there is excess moisture in the home, condensation easily takes place when this moisture gets into contact with cold surfaces like walls and windows. The water droplets that are formed cause the home to become damp.

The sub floor is also a contributor of rising damp in the home. Excessive moisture in the sub floor could be caused by pools of water that collect after a storm. Leaking pipes and insufficient ventilation all play a role in causing damp conditions in the under floor. The damp in the under floor causes decay of timber and encourages termite attacks. Any metals used in the sub floor become corroded and the structure of the home becomes compromised.

Home ventilation can be used as a method of managing moisture build up in the home. There are different ventilation methods that can be used to ensure your indoor air is fresh and dry. Some of the ventilation methods include:

  • Whole house ventilation
  • Sub floor ventilation

Whole house ventilation systems are mechanical systems used in homes that are insulated for energy efficiency. There are different types of whole house ventilation systems. These include balanced, supply, exhaust and energy recovery systems.

  • The balanced ventilation system is made up of two fans and two ducts. The positive pressure fan forces in fresh air into the home while the negative pressure fan expels almost the same amount of stale air from the home.
  • The supply ventilation system uses a positive pressure fan to bring in fresh air from the outside. This creates positive pressure in the home that forces out the stale air through vents and other openings in the home.
  • Exhaust ventilation systems use a negative pressure fan to pull out stale air from the home, creating negative pressure. This forces fresh air from the outside to rush into the home through vents and other openings.
  • An energy recovery system ventilates the home while ensuring that energy losses are minimal. They work by transferring heat from the stale outgoing air to the fresh incoming air.

Sub floor ventilation systems can either be supply, exhaust or balanced. Our ventilation experts are skilled in the installation of all types of ventilation systems. We can install a whole house ventilation system that includes sub floor ventilation. We can also install a stand-alone sub floor ventilation system for your under floor.
