Managing Mould

Managing Mould

Managing #mould. It’s everywhere, so how?

Managing mould doesn’t have to be an uphill battle.

Mould spores are everywhere, and they are waiting for enough moisture to reproduce. 

So… ultimately, mould is a moisture issue

Without moisture, most mould will not survive.

Different moulds have different moisture requirements, which means that even if you live in a very dry climate, you may well have mould-related issues, but the types of mould will be different to what would be found in a humid climate.

I often talk to clients about this and because it allows them to be proactive.

I am a strong believe in informed choices and taking action – so that you aren’t being reactive…

Moisture is Something We Can Control

I focus on this element as this is what we can control. This is where we can play an active role in keeping mould at bay.

Managing Mould At Your Place

Since mould is a moisture issue, we are going to focus on moisture.

Moisture can come from weather-events, building-related issues and occupant activity. Today, we are going to focus on occupant activity – this is what you do within your “four walls.”

My top 5 sources of increased moisture include:

  1. Bathing – showering or bathing
  2. Using the clothes dryer
  3. Hanging laundry inside
  4. Cooking, especially with gas 
  5. Breathing

These are all regular events in most households, so what can you do?

The first step is to monitor the levels of relative humidity (RH) to help keep mould at bay. The ideal range is between 45-55% RH. 

To understand more about humidity, please read this post.

A simple and inexpensive way to monitor RH is with a hygrometer – you can get a simple one here

Some Simple Steps

Based on my top sources of moisture, managing mould can be done simply and easily by following these seven simple steps.

  1. Use the extractor fans when bathing, cooking or doing the laundry
  2. Dry your laundry outside
  3. If you do have to use a dryer, vent the dryer to the exterior
  4. Make sure you use the extractor fan every time you cook. If you don’t have one, then open windows to all for cross-ventilation
  5. Open your windows and doors! It can take as few as TWO MINUTES to exchange the air in your home. It is essential to do this as often as possible – at least 6 times day
  6. Consider a dehumidifier (especially if your extractor fans vent to the ceiling void, and not outside)
  7. Consider an air purifier to help to keep the air clean
