Regardless of the season, water damage can happen at any time of the year. Whether it is caused by snow and ice thawing or a torrential downpour, if water enters your basement, it can become very dangerous. When most people think of water damage, they mostly think of dollar signs. A flood in your finished basement can destroy everything it touches, but most people don’t think about how dangerous basement water damage can be.

A basement flood can be devastating, and most insurance policies don’t cover water in your basement, regardless if it is a flood. You may be immediately concerned with the damage of your possessions, but when it comes to flooding, these items aren’t the only thing that you should be worried about.

Keep reading to learn more about the dangers associated with water damage in your basement, along with how to prevent water damage, how to spot water damage, and what you should do if your basement floods.

What To Do If Your Basement Floods

If you notice that your basement has flooded, the first thing you should do is contact the professionals. You may be tempted to enter the basement to save your personal items, but this can be very dangerous! There are several items located in your basement that require electricity to function. This means that these items may have come in contact with the water which can lead to electrocution if you are not careful.

Mould, Mildew, and Fungus

Another dangerous aspect that is associated with water damage is mould, mildew, and fungus. Mould, mildew, and fungus love to grow in environments that are wet or damp. There are many serious health concerns when living in an environment that is growing mould, mildew, or fungus. Some of these issues include:

  • Eye irritations
  • Respiratory problems
  • Skin rashes

There are many other issues that can be caused by exposure to mould, mildew, or fungus. These issues are even more severe for the eldery, children, and those with medical issues such as asthma. Long term exposure to mould, mildew, or fungus can lead to serious issues including memory problems and brain damage. The best way to avoid mould, mildew, and fungus from growing in your basement is to ensure that your basement is completely water free.


Another aspect that you must consider when you have water damage in your home is the effect it has had on the structure of your home.

Beyond the damage to your foundation, the water can also damage wood and support beams. The water can cause them to rot which can severely degrade the structural integrity of your home.

The complicated part about structural damage that is caused my water entering your basement is that it might not always be obvious. That’s why even if there is a small leak in your home, we suggest that you contact the basement waterproofing and basement foundation repair experts at GJ MacRae.

Property Damage

Another aspect of water damage in your basement is property damage. Your drywall and floors may be destroyed, and so will all of the personal items that you’ve stored in the basement.

Drywall and water don’t mix. Drywall is the product that your walls are made of, and when it comes in contact with water for an extended period of time, it cannot be saved. Not only will the drywall sheets lose their integrity, they will also become a perfect place for mould to grow.

Many people never expect to see their sofa floating in their basement… but sometimes floods happen! Furniture that gets wet is often hard to salvage. Couches hold water and begin to grow mould and wooden items begin to peel and smell. You may be able to save these pieces if they aren’t exposed to the water for too long, but often times it is best to cut your losses and replace them in order to keep your home and your family safe.


It is not safe to enter the water damaged area until all the power to your home has been shut off. We suggest leaving this to the professionals so that there is no risk of injury to you or your family.

Water damage and electrical outlets and appliances can cause serious issues. When water enters your home, it travels wherever it can. This means that it can enter your electrical outlets and all of your appliances including:

  • Furnaces
  • Water Heaters
  • HVAC Systems
  • Washer & Dryer

These items can become corroded by the water which can put your and your home in danger is they are used after getting wet. We suggest that you contact an expert to examine all your appliances prior to using them after any water enters your home.


Another thing that is attracted to wet, dark spaces is pests. From mice to rats, cockroaches to other insects, when you have water damage, they will come. Not only are these unwanted creatures unpleasant, their waste has been linked to triggering asthma attacks and other respiratory issues. It is important to make sure that the damaged space is dry and that the source of the leak is fixed so that you don’t have to call in an exterminator!
