The Dangers of a Flooded Basement and How to Avoid Them

September 21, 2022

A leaking pipe, cracked window frame, and holes in a wall could all lead to a flood in your basement.

A flooded basement is one of the most frustrating and potentially expensive issues that you could face as a homeowner. According to CityNews Toronto, the average basement flood costs more than $40,000 in Canada.

Fortunately, there are steps you can take to reduce your risk of a basement flood. What are they? We’ll cover them later in this post.

First, though, we’ll look at some of the most common dangers associated with a flooded basement.

What are the Risks of a Flooded Basement?

Severe Damage to Your Property

A basement flood can cause damage to your home even if the water is removed quickly.

For example, paint on your basement walls may start to peel in a damp environment. Water damage could also create stains on your walls and flooring. And wooden furniture could become damaged if soaked in a flood — you would either need to repair or replace it.

However, the damage could be more than just superficial. Water may cause wood to rot in multiple areas of the basement, including door frames, window frames, and support beams.

Drywall may be damaged in a flood, too, which might affect the structural integrity of your home. If you believe water has damaged your drywall or support beams, it’s crucial that you bring an expert in to assess the situation immediately.

Creating a Breeding Ground for Mold

Mold is one of the most serious problems associated with basement floods, as damp or wet spaces are ideal breeding grounds for mold.

Mold may start to form over time, and while it may initially appear in an isolated corner, it could eventually become a bigger issue throughout your basement. That’s because mold spreads from surface to surface via airborne spores.

Not only does mold create a highly unpleasant musty smell that can turn your basement into a no-go zone, but it also poses a risk to your health. How? Those spores that allow mold to spread may trigger allergic reactions if inhaled. For example, you might develop a runny nose, a rash, sneezing fits, red eyes, and even asthma attacks.

Certain members of your household may be more sensitive to mold than others. Elderly relatives, babies, young children, and anyone with respiratory issues or a weakened immune system could be at higher risk of a bad reaction.

Attracting Pests to Your Home

A wet or damp, dark basement could attract more than mold — you may find insects, rats, cockroaches, and other pests invading your home. You may assume that’s hardly the end of the world if you rarely (if ever) go down into your basement. But any droppings they leave around your property could pose a health risk if you or any other members of your household come into contact with them.

Additionally, rats and mice (and their droppings) could trigger asthma attacks in vulnerable individuals. The sooner you remove water and dry your basement out after a flood, the less likely you will be to develop a long-term pest problem.

Triggering Potential Electrical Dangers

Most of us have one or more appliances in the basement, as well as other electrical items. For example, maybe you like to play video games in your basement for some alone time or you store power tools or your washer and dryer down there.

Whatever electricals you keep in your basement, water damage could turn them into a health hazard. Water coming into contact with an appliance or an electrical outlet may leave them too dangerous to handle. It’s not worth the risk to use them before they’re checked by a professional.

Make sure your power is shut off when you enter a flooded basement for the first time, and stay away from electricals that may have been damaged by water.

What Can You Do To Avoid a Flooded Basement?

There are various ways to protect your basement, and the rest of your home, from a flood.

One option is basement crack repair, involving traditional techniques like caulking and troweling to prevent water from seeping in through damaged areas of flooring or walls.

An exterior waterproofing service is another solution. A reliable team will dig down to your basement’s foundation to fix and seal any cracks or holes. They will apply a bituthene primer and delta membrane to the foundation, and run a weeping tile test to identify potential issues with water leaving your property properly. New weeping tiles will be put into place next to footings, with gravel added to facilitate effective drainage.

With exterior waterproofing, you will enjoy peace of mind knowing that water will  be unable to enter your basement as it might have previously.

With interior waterproofing, a team will create a trench running around the foundation wall and install a drainage membrane and a weeping tile system. Gravel will be placed on top of the weeping tile, and the weeping tile itself will be connected to a sump pump (either a new one or your current one). That will ensure water is removed from your basement and deposited outside of your home before it can turn into a flood.
