A mold inspection starts as a home inspection, which is a non-invasive, visual examination of the home's interior and exterior, and its various systems and components.
The scope of a mold inspection requires particular knowledge of HVAC systems, roofs, the exterior, and plumbing systems. Musty odors, moisture intrusion via a roof or plumbing leak, or even evidence of suspected mold can warrant a mold inspection.
Once mold gets a foothold, it cannot always be completely eradicated, so the best cure is prevention. Homeowners must be vigilant about checking for leaks both inside and outside, and making sure their home is free of conducive conditions - the main culprit being water. For instance, firewood stacked up against the side of the house can retain moisture from dew, rain and snow. Leaks should be fixed as soon as possible. And indoor humidity and moisture should be controlled by making sure appliances, such as the clothes dryer and dishwasher, are vented properly, and that the vents themselves are operating as they should. Windows are another place prone to mold growth if the frames are old and damaged, or the seals on the panes have failed. And basements and crawlspaces are notorious breeding grounds for mold, especially if they're used only for storage, the windows are old or damaged, and/or the area experiences occasional flooding. All of these things fall under the category of home maintenance, which Woodard Inspections can educate their clients about.
Mold testing involves two main methods: air sampling and surface sampling. Both types require analysis by a certified laboratory. Woodard Inspections is trained to know when to offer what test is and this service is not part of a standard home inspection.
Along with the sampling equipment, the tools commonly used by home inspectors for a mold inspection of the home's interior include some of the following:
Air sampling is conducted indoors and outdoors using spore traps or canisters. This less-common method is used for homes in areas suspected of having high concentrations of mold spores. The outdoor samples are used to create a control or baseline to determine the level of contamination, and then the control is compared to the indoor samples. When taking the outdoor sample, the home inspector should be alert to environmental conditions that can affect the results, such as wind, rain, snow, and fluctuating temperatures.
Surface sampling is the more common and easiest method for testing for indoor mold.
Here are some methods of surface sampling that can be performed:
When it comes to mold, prevention is the best way to combat it. A damp or musty smell is a likely indicator and should be investigated thoroughly. Homeowners should be encouraged to locate and repair all plumbing leaks and sources of water intrusion, which can quickly lead to mold growth. Woodard Inspections is trained to identify mold, as well as conducive conditions and where mold is likely to grow. Mold testing is offered as an additional service for a fee and falls outside of the scope of the standard inspection.
