Our Best Basement Mold Prevention Tips

Mold isn’t something anyone wants in their home, but unfortunately it can show up when you least expect it in areas where you least expected it to. Mold, while also unpleasant to look at, can also cause risks to you and your family’s health. Keep reading to learn more about basement mold and the steps you can take to prevent it from growing. How and why does mold grow in your basement?


We’ve all come across a moldy basement in our time. There’s something about that one subterranean area of the house that seems to attract mold and fungus more than any other. However, why is that? There are many possible causes — but usually, the main root of the issue is the fact that concrete is porous and sponge-like when surrounded by moisture. This tends to be less of a problem above-ground where the weather is changeable and your walls’ contact with water is limited to short bursts. Underground, however, is of course a different story.


Moisture from the ground is in constant contact with your basement — and if your foundations aren’t properly prepared for this, it can leach into the wall. This can create the perfect conditions for fungus and mold to prosper.


What are the consequences of a moldy basement?


We’re all familiar with the musty smell — it’s unpleasant, off-putting and a tell-tale sign of mold in a basement. Mold can cause serious health problems when human lungs are exposed to their spores for any amount of time. At the very least, it can cause respiratory issues such as coughing and congestion (and in especially bad cases can produce toxicity). It’s also not just lungs that can be damaged — a mold infestation can also cause material damage to books, wallpaper, paint. Left untreated, it can also cause structural damage to drywall and timber framing.


What can you do about it?

It’s important that as soon as you notice mold in your basement, you take action. Mold is an agent of decay, so it’s important that homeowners do their best to keep it at bay. Not practicing mold-control can end up being costly and extremely inconvenient in the long run. Here are a few steps you can take:

  1. Look for moisture - Before the issue even takes root, it’s a great idea to look for areas that could become home to a mold infestation. Look for wet patches, condensation, discoloured areas of concrete and check that your basement is well-sealed from the elements. Chipped windows, loosely fitting outside doors and cracks in your walls can all become unwanted sources of moisture.

  2. Know the signs - Keep an eye out for the telltale black spotting on walls and pay attention to the smells in your basement.

  3. Do a basic treatment - Once you have identified a mold issue, it is a good idea to take some basic steps to treat it topically. There are many consumer-grade mold sprays and fungicidal paints that you can use to patch up the issue in the short-term.

  4. Bring in an expert - While sprays and paints are useful to try to keep the problem under control, the issue will not be resolved until the underlying problems with moisture in your basement have been corrected. This will generally require the help and advice of a professional.
