Mold is a byproduct of the breakdown of organic matter, such as plants, wood, and even food and certain beverages. The problem posed to humans by mold is their spores, which can be released into the air and land on damp surfaces indoors, where they will continue to grow if the conditions are right. Mold growth left unaddressed can quickly spread and result in damage to the structure of a home. More importantly, mold can compromise the respiratory health of susceptible individuals.
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 InterNACHI® Certified Professional Inspectors® can educate their clients about.
