Here’s How You Can Prevent The Spread Of Mold In The Home?

There is no guarantee that mold can be completely eradicated, so therefore prevention is the best remedy. The first step is to be vigilant about checking for leaks both inside and outside, and sure the home is free of conducive conditions.


For example, do you have firewood stack up against the side of the home? This alone can retain moisture from dew, rain and snow. The points below should be taken into consideration for preventing mold in the home. Here are some other things that you should consider during your home maintenance routine:


  • If you notice any leaks, fixed them as soon as possible.

  • Indoor humidity and moisture is another factor to consider, make sure that your clothes dryer and dishwasher are vented and operating as they should.

  • Last but not least, check your basements and crawl spaces, as they can be notorious breeding grounds for mold, especially if the windows are old, or damaged, and or the area experiences occasional flooding.


What Are Methods For Mold Testing?

There are two main methods for mold testing. Which are air sampling and surface sampling. Both types require analysis by a certified laboratory. The mold sample can be tested by local health department or by a private lab. It’s more common for a private lab to perform the analysis and generate the results in the report.


Besides sampling equipment, the tools commonly used by the home inspector during the mold inspection include the following:

moisture meter: This basic tool is used to detect moisture in structural components. There are invasive and non-invasive models available.

  • humidity gauge: This measures the humidity level inside a room or building.


  • thermal imaging or infrared (IR) camera: Where visual inspection is not possible, especially for suspected water intrusion that's inside structural components, damp and wet areas can be detected non-invasively with thermal imaging. Problem areas will show up as dark gradients.

  • borescope: This is a camera that can visualize suspected mold growth and other problems inside plumbing pipes and structural elements through an opening in the component.

  • rotameter: This device measures the air flow rate, which can be helpful to determine if the home has conducive conditions for mold growth.



Air Sampling and Surface Sampling


Air sampling can be conducted indoors and outdoors using space traps and canisters. Although a less common method, it is used for homes in areas suspected of high concentrated of mold spores. The more common and easiest method for testing for indoor mold is surface sampling.

Here’s a look at some sampling methods that can be performed.


Here are some methods of surface sampling that can be performed:


  • Tape sample: This is the most common method of sampling visible mold, as it allows the inspector to collect several samples in different parts of the home quickly. Sampling kits are typically sold by the laboratories that test for mold and send back the results of their analysis.

  • Swab sample: A cellulose swab with a liquid preservative is used to collect any suspected mold for laboratory testing.

  • Carpet sample: In rooms where there is carpeting, testing can be performed on vacuumed contents, or even a snip of the carpeting. Typically, carpets that have visible mold or have tested positive for mold should be discarded and replaced, as it's nearly impossible to remove all traces of mold from carpet fibers, where mold will likely continue to grow.
