Why “killing mould” is simply not enough


There are many different approaches to mould remediation. Some methods include the use of chemicals, some involve physical mould removal and others involve a combination of the 2 methods.

In the area of mould remediation there are quite a few issues that arise:

Has the cause of the mould been dealt with?

There is no point remediating mould if the source of the mould has not been dealt with. The mould will simply keep coming back and will continue to cause issues. The source could be caused by water leak, poor ventilation, humidity or a multitude of other reasons. If mould is found in a property the first thing to do is to identify the reason for the mould and to fix this issue properly.

Is the person looking at your mould issue really an expert in mould?

There are so many self proclaimed professionals out there claiming to have very cheap mould remediation strategies. Generally if something sounds too good to be true, it is not going to fix the problem. Unfortunately when dealing with mould there is not a simple solution. If you do not get a professional to assess the situation to start with, it could cost a lot more than the initial cheap price. We would recommend that you hire an independent environmental professional to test the property and assess the extend of the mould and moisture and to suggest suggested actions. I would ask the expert a few questions:

(a) What standard are you recommending work is completed to? Work should be completed to the IICRC S520 Mould Remediation Standard.

(b) What remediation qualifications do they have? They should have the IICRC Applied Microbial Remediation Certification as a minimum. This course teaches professional to conduct assessments and remediation work to the IICRC S520 standard.

(c) What knowledge do they have about mould, how mould grows and factors in the environment?

(c) Is the person independent or do they have something to gain from giving you specific results?

Does the person know how to sample mould?

Knowing how and where to take samples is extremely important. This can mean accurate results which reflect the indoor environment and the actual mouth growth.

(a) Is the person testing for both viable (alive) and non-viable (dead) mold spores?

(b) Have the sampling tools been used in an ethical way to get accurate results?

(c) Is the person sending the samples to a reputable mould laboratory who specialises in mould?

To ensure that a mould job is dealt with properly the above points need to be taken into consideration.
