Mold Sampling

Does your building have a mold problem?  Our professional mold sampling provides many important pieces of information:

The Presence of mold.  Several types of sampling are used to determine if a suspected area contains mold growth. 

The  Types of mold.  Stachybotrys, Aspergillus, Cladosporium.  Distinguishing between different types of mold growth is indecisive without laboratory sampling.  Our mold testing accurately determines the species of mold growth in your building.

The Quantities of mold.  We measure the quantity of mold to determine if a mold problem is present.  Even in the cleanest of buildings mold is present.

Identifying the problem and determining the probable cause.

First, we pinpoint the problem areas in your building.  Where is the mold growth?  Basement, crawlspace, attic, or concealed in a bathroom wall?  All of these are common locations for mold growth. 

Second, we determine the probable cause of the mold growth.  Mold requires 3 conditions to grow, moisture, a food source and the right temperature, therefore we look for a source that has all of these conditions.

Some common conditions that facilitate mold growth include:

Plumbing Leaks      Foundation Leaks   Roof Leaks    High Humidity

Third, We outline our recommendations and provide expert advice and consultation tailored to your situation.

FAQ's - Professional Mold Sampling & DIY Mold Test Kits

How many mold samples do I need?

The amount of mold samples needed is typically based on the size and design of the building. Generally a minimum of 3 samples are required and more if conditions warrant.

I know I’ve got a mold problem, do I still need testing?

Mold growth occurring indoors produces a wide variety of affects on the indoor air quality. To accurately determine the location, types and quantities of mold require sampling.

What is the most common type of mold testing?

Non-viable air sampling is the most common type of testing used in a mold inspection. This test provides us with two key pieces of information: the type and quantity of mold spores present in the indoor air.

How long will it take to get the mold report?

Laboratory results are typically available within 2-3 days. After the samples are collected, they are shipped to a certified laboratory. Here they are analyzed and a report is generated and sent electronically to your Mold Inspector. Your inspector will then provide you with this report and explain the results make any recommendations.

What is the difference between professional mold sampling and mold test kits available in hardware stores?

Several types of DIY mold testing kits are commonly available at hardware stores. Typically these rely on a Petri dish sampling technique. Though inexpensive, unfortunately these kits provide very little useful data. Petri dish sampling relies on gravity to bring mold spores onto the collection plate. These spores are then allowed to grow in ideal conditions. The problem of course is that mold spores are everywhere. With Petri dish kits, even the cleanest house will show a mold problem. Professional testing follows a scientific methodology of collection. A uniform amount of air is passed through a collection cassette. This is compared to an outside control sample collected in the same manner. This comparison allows us to accurately determine the amount of mold spores in the air.

                     Mold Inspection And Sampling

    A thorough mold inspection involves two main components, a visual inspection and sampling. The visual inspection focuses on identifying the extent of the visible mold growth and the conditions conducive to mold growth.

    Depending upon the scope of the inspection the process is either limited to a specific portion of the building or encompasses the entire property. Visual inspection and air sampling will identify problem areas that may be adversely affecting your Indoor Air Quality.

    Indoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria, allergens), or other contaminants that can induce health effects.

    Techniques for analyzing IAQ may include collection of air samples or collection of physical samples on building surfaces. The resulting samples can be analyzed for mold, bacteria, allergens.  These investigations can lead to an understanding of the sources of the contaminants.
