Frequently Asked Questions about Mould and Moisture Damage

What causes condensation?

Condensation is caused by excessive or trapped moisture in the built environment. The moisture is caused by either a water ingress (typically when there is a burst pipe or a flood etc) or by an atmospheric imbalance (when the dwelling is too cold and poorly ventilated). Condensation is the moisture in the air which, as the house cools down overnight, falls from the internal atmosphere and condensates on the coldest surfaces in the affected area.

How do I get rid of condensation?

Condensation is dealt with by removing the excessive moisture from the internal environment. Adding heating will delay the onset of condensation for the simple reason that warm air can suspend more moisture for longer than cooling air. The two critical factors when dealing with condensation are ventilation and heat. By combing the two condensation will be eliminated, provided of course that the source of the moisture has been resolved. Often adding heat and practising ventilation daily can be enough to reduce or eliminate condensation. Other times, mechanical ventilation is required, typically in well sealed modern apartments.

Why do I have both condensation and mould at the same time?

Mould can ONLY grow when moisture is present. Without moisture there is NO mould. So once condensation is occurring, mould growth will inevitably follow.

What is rising damp?

Rising damp is damp or moisture which rises vertically via capillary action through masonry building products like bricks. The moisture can be trapped moisture in the subfloor, or moisture in adjacent soil or concrete. If moisture laden soil or concrete is pressed against the brickwork of the dwelling, it transfers from the soil or concrete into the brickwork and will then rise up in the brickwork, manifesting itself as salty deposits on the brick work.

Is Rising damp dangerous?

The salt deposits found in the rising moisture is cancerous to the masonry brick work of the dwelling and if left for long enough, will ultimately destroy the mortar and eventually the brick work. However, this is a very slow process and can take 20 years or more to cause long term damage to the bricks or mortar.

What is mould?

There are two kinds of mould - visible mould and non visible mould. Non visible mould - mould spores -  is one of the seven particles that are found in household dust. If you have dust you have mould spores. Once moisture is added, the non visible mould will germinate as visible mould growths. Mould growth will generate more mould spores.

Can I remove mould myself?

Yes easily. Simply mix vinegar and water and spray onto mould growth and wipe off. There may be some residual staining following remediation.

Why does the mould return after I have cleaned it off?

This is because you have not addressed the underlying cause of the mould - moisture. The mould has grown for a reason and the reason is that moisture is present. The moisture issue must be dealt with at the same time as the cleaning of the mould.

Can I get rid of mould spores from my property myself?

Yes you can. Mould spores can be dealt with as you would deal with dust - by constant vacuuming and ventilation. Even the professional equipment which is used to remove mould spores simply filters the internal air via a HEPA filter which traps the particles as they are drawn through the filter. Vacuming and ventilation will achieve the same end result.

My bathroom tiles are leaking. Can I just seal the tiles? There are some companies who offer this service.

You can but you will not be treating the underlying issues that have bene created by the moisture leak - mould growth timber damage and wood rot. It is always best to deal with the issue properly the first time and this will involve removing the tiles, drying and waterproofing the substrate under the tiles and then retiling. More expensive but the only way to resolve the issue permanently.

Inspect for Moisture & Damp

  • Thermal imaging cameras detect moisture and danp problems behind walls.
  • Inspection cameras can detect mould and rising damp in areas that may not be accessible.
  • Penetrative and non penetrative moisture metres can detect moisture and damp on wall surfaces and inside wall cavities.
