What is Mould?

 

Mould spores exist readily in nature and are an important part of plants, soil and natural decay. In the outdoors, moulds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees. However, indoors mould growth should be avoided since it will break down building materials and can cause extensive damage. Moulds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mould may begin growing indoors when mold spores land on surfaces that are wet and contain cellulose materials such as dust, paper, wood, cardboard and fabrics.

After a proper assessment a mould clean up protocol can be created where we will put you in touch with our qualified contractors that can then safely remove the mould growth.

How does mould grow?

Mould needs food and water to grow. The food is any cellulose material such as soil, wood, paper, organic debris, dust, fabric, drywall, carpeting, etc. The water can come in the form of high relative humidity, small water leak or flood.

Why is mould growth a concern?

The difference between mould growth outdoors compared to indoors is that outdoors there are a wide variety of mould types (genus and species) that keep each other fairly balanced.

Indoor mould growth usually involves one or a few types of mould species that greatly outnumber the concentration found indoors even outdoors. Mould amplification indoors is usually due to a moisture problem which will continue to fuel mould growth. As time goes by the problem can become larger, more severe and more difficult to clean up.

If the mould species found indoors is considered toxic or pathogenic and in large enough numbers, then a variety of health effects can occur.

Health effects can range from simple head aches, sinus or breathing problems to more severe nose bleeds, skin rashes, bleeding of the lungs, cancer, even death.

If I find mould why don’t I just remove it and not bother testing it?

In some cases that is sufficient. However, you don’t necessarily need to see mould growth in order to have a significant mould problem. Some moulds grow inside the wall cavity without any evidence at all on the visible portion of the wall.

In many instances mould may be visible in one room of a building, but the source of the growth is in another room or portion of the building which does not show visible evidence of growth in readily accessible areas.

Some of our investigations have resulted in significant mould growth findings where no mould growth was even suspected.

I found mould and have reduced the relative humidity to 30% to dry it out.

Although high relative humidity can cause mould growth, reducing the relative humidity to very low levels like 30% to dry out the mould is not advisable either. Drying out the mould can increase the chance of it aerosolizing. Mould has a natural defense mechanism where if disturbed, attacked or is dying, it will send out potentially millions of spores into the air that will settle and grow elsewhere. Avoid high relative humidity, but also avoid drying out. A relative humidity of 40% to 50% would be more advisable and have the mould tested and removed.

I found mould growing in a corner of my bedroom. I will just replace the drywall.

If you have mould growth you need to know why and how much. The source of the mould should be identified in order to avoid the problem repeating itself. If there is a roof leak or other moisture problem it needs to be fixed.

A mould test should be performed to determine how bad the mould problem is, what type of mould it is and if it’s in any other portion of the building. With this data a proper method of removal can proceed. In some cases a carpenter can replace the drywall. In other cases the unaffected portions of the building, the occupants, and the people doing the mould remediation need to be properly protected.

We just bought a house and will be renovating. How can a mould test help.

Especially in scenarios where you don’t really know the history of the building, it is advisable to test for possible mould amplification before removing walls, carpeting, or doing another structural work. If you start removing drywall and see the back side of it black with mould it is in many cases too late.

Sick Building Syndrome or Building Related Illnesses are increasingly the result of either careless building maintenance, careless renovating practices, or toxic mould exposure caused by aerosolized mould spores due to the removal of building materials without proper mechanical safe guards.

With this in mind, do not delay getting your mold situationt taken care of because it could have big ramifications to the well being of your family. You can use our mold removal Toronto service to get rid of the problem immediately.
