They can however, cause a variety of health problems. When mould growth is disturbed or improperly removed, mould can produce spores that can affect furniture and other belongings causing a more wide spread mould issue. In addition, inhaling mould spores is what triggers the health issues related to mould growth indoors. The age of the building has no bearing on whether there could be a mould growth issue.

Mould Inspection - Mold Inspection

An air quality assessment together with a mould inspection can uncover hidden sources of pollutants in your home or office. A proper mould inspection should never be just a quick visual inspection and a few laboratory samples. Although this approach is a cheaper, the results could be misleading and falsely determine that you have mould growth or falsely determine that you don't have an indoor mould growth problem. It’s almost like a doctor not taking the right amount of tested to determine your ailment and then guessing what’s wrong.

If you dont’ use a mould detection dog, it may be a guess!

Proper mould assessments should begin with a comprehensive instrument survey for air quality to identify and locate hidden pollution levels indoors. This will assist in determining where and what type of laboratory analysis is appropriate and will assist in identifying the cause of an indoor mould problem. A qualified mould inspector should also identify the source and extent of the moisture damage that lead to the mould problem using thermal imaging and moisture meters. This can determine if area are still actively growing mould. Finally, the mould detection dog can locate specific areas of mould growth and can determine whether the issue is in one specific area of a room or the entire room.

Why tear apart an entire room to find it’s just a mould problem in one corner?

A proper instrument survey for air quality, thermal imaging and moisture survey, mould detection K-9 and a series of surface and air samples for mold spores can provide the mold inspector with detailed information on the cause, source and solution of the mold growth issue in your building.

If you have a mold issue, believe you have a mold issue or are unsure whether mold or air quality problems are affecting your us today.

Mould in your home or office can be a scary thing...but it doesn't have to be. Let us us show you how.



If you see mold growth it is important not to disturb it until you have a clear understanding of the severity and extent of the mold issue. Touching, cleaning, spraying with a chemical or any other action that disturbs mold growth can release thousands of spores into the air. In some cases this can make the mold growth problem much bigger and can result in higher clean up efforts.

A proper mold inspection will result in a scope of work for a remediation company to follow to allow for the proper and safe removal of your mold issue. In some cases, we can also guide you through the mold clean up yourself if the mold problem is small enough.


If you have had any kind of moisture issue indoors, you could have a mold growth issue. Moisture damage can come from a flood, a leak or even sustained elevated humidity or condensation. You do not necessarily have to smell mold or see mold to have a mold growth issue. Mold likes to hide behind walls, behind baseboards, under flooring and above ceilings.

A mold free environment also does not exist so it is important to have a proper mold assessment performed. A well executed mold inspection can give you the location, extent and severity of the mold growth area and airborne mold spores.


If you have had mold growth cleaned up, removed or may wish to have a Post Remediation Verification Assessment done. This type of mold assessment can determine if the mold issue has been cleaned up properly and if the mould spore levels in the breathable air have returned to normal.

Even when mold remediation has been performed properly by a well trained and experienced contractor, mold spore levels can remain elevated...unless tested.
