mould remediation in Oakville, Burlington, Hamilton

Do you have a moldy or musty smelling basement?

Mold is never fun. It’s not even a fun word to say and finding mold anywhere in your house is never fun.

One of the most common places you can find mold in your house is in your basement.

But what causes mold to grow in your basement?

Is there anything you can do to prevent mold from growing in your basement?

And if you think there might be mold, how can you find it and how can you remove it?

All great questions.

How Does Mold Start To Grow In A Basement?

Moisture can seep into a basement in a variety of ways and the moisture can come from a variety of different sources. First off, any water or dampness problem that you might have in your basement takes a very long time to properly dry out.

This is because most basements get hardly any sunlight, are very poorly ventilated, and basements are often humid.

This is a perfect environment for mold to form and grow.

To make matters worse, once the mold has started to grow in your basement, it will probably go unnoticed for a long time since people don’t usually spend that much time in their basements. Of course, this depends on the type of house you have.

Also, when was the last time you cleaned your basement? Really cleaned your basement? People hardly ever do and the dust and dirt that builds up over time also help mold grow.

What Causes Mold To Grow In The Basement?


High humidity in the summer, the cold temperatures of the winter, and the usual wet spring all factor into creating a lot of condensation in a basement. Condensation collects on metal peoples, cold concrete basement floors (even if there is carpet over top) and on walls.

Flooding and Basement Mold

Perhaps the biggest cause of mold forming in a basement is the most obvious one – flooding.

If a house is flooded, the water runs down to the basement and stays there long after the other rooms have dried.

This is where you really have to be careful as dangerous molds like toxic black mold (Stachybotrys chartarum) can start to grow after a flood. These molds need materials to be very wet for several days to begin growing.

How To Prevent Mold After A Flood?

So you had a flood in your house – not good. So what are you supposed to do after a flood happens?

The best thing you can do is to contact a mold remediation company or water damage specialist who performs cleanups of homes after floods.

If you decide to try and clean up your home yourself, here is what you need to know:

  • Clean and dry your house and everything inside as soon as possible. Get rid of any standing water that you can. Use fans, air conditioning units, heathers or dehumidifiers to help dry out your home faster.
  • Get rid of any wet materials from your home immediately. Wet insulation and wet underpads from carpets can take a very long time to dry out and so you need to get rid of them. Unfortunately, any drywall that got wet also needs to be cut out and removed. You should replace these materials only after your home has completely dried out.
  • Clean items in your home that got wet using a detergent or cleaning product and then let them dry out. As a general rule, you should throw away things that got wet from flood water and which can’t be cleaned or dried. Also clean hard, non-porous surface in your home and let them dry out.

What To Do About Mold From Basement Leaks

Another common problem that leads to mold growing in a basement is leaking pipes. But that’s not all, water in the ground can also find its way into the basement through cracks in the wall.

Once the water in the basement has evaporated and gone away, it causes the humidity levels in the basement to go up. The humidity then usually stays high thanks to most basements having poor ventilation and hardly any sunlight. Some molds can start to grow in the basement just from these high humidity levels.

How Can You Find Mold In The Basement?

When looking to see if you might have a mold problem in your basement, you should start by trying to find any signs of moisture. Areas where there are signs of water damage or leaks are likely spots for mold growth.

Mold can grow anywhere. On items and building materials made from organic substances. In the basement these surfaces can be found everywhere – drywall, wooden building frames, carpet, insulation, wallpaper, furniture and cardboard boxes are just a few examples.

If you cannot find any mold in your basement, it doesn’t mean that it’s not there. It just means that perhaps you can’t find it. Don’t forget that you always have the option of getting mold testing done, and the sooner the better.

Mold testing can be performed by professionals for you, or you could visit your local Home Depot and buy a do-it-yourself mold testing kit. Both air and surfaces should be tested for mold spores during any mold testing.
