What Causes Household Mold?

5/4/2018 (Permalink)

What are the most common causes of mold in homes?

The unfortunate reality is that problematic mold can really pop up anywhere that isn’t dry. We see it most often in attics due to roof leaks, poor air circulation, and bathrooms that ventilate into the attic rather than outdoors; crawl spaces because earthen or gravel flooring allows moisture and spores to rise from the soil; basements that have flooding from foundation leaks or plumbing leaks; and interior living spaces with leaks, bad windows, and high humidity.

Is there a chance I have mold and don’t even know it?

There are four criteria that you should be aware of:

  1. A musty odor is caused during the colonization of some fungal species, but can come and go depending on moisture levels and air current changes.
  2. If you have water staining or if building materials have discoloration that’s spreading over time… that may be a sign of mold.
  3. Mold spores that were already present will begin to colonize just 48 hours after a water event.
  4. Health Effects. If your allergy or respiratory symptoms begin to worsen or if you feel worse in certain indoor environments and better when you leave that space, you may have mold.

What is the removal process like?

The remediation process (providing a remedy to a known mold issue) involves three things: Killing the fungi, removing the dead mold, and protecting against future mold growth/colonization. In order to do this, professionals have a multi-step process that he uses:

  1. Contain work area and apply negative air pressure HEPA air purifiers to prevent cross-contamination.
  1. Mist EPA registered anti-microbial to suspend and kill mold spores.
  1. Remove affected building surfaces.
  1. Bag and dispose properly
  1. Treat cavities/underlayment and dehumidify.
  1. Abrasively remove dead loose mold.
  1. Apply EPA registered protective sealer.
  1. Perform clearance testing.

Why is it important to hire a professional?

It is always a good idea to consult with an honest mold professional. If there’s an issue you can tackle yourself, they should give you recommendations about how to do so. Honestly though, it may be a bit too much for a homeowner to keep safe while preventing cross contamination, killing mold, removing it and preventing new mold from growing. That’s when a professional is necessary, so you can get things done properly.
