Is it Safe to Stay in a House With a Flooded Basement?

If your home has been affected by flooding, you may be wondering if it is safe to stay in the house. In this guide, we will discuss the risks associated with staying in a flooded home and provide tips for keeping yourself and your family safe.

What to do if Your House Floods

If your home has been affected by basement floods, you will need to take action immediately.

Here are some tips for how to handle a flood situation:

If the flooding is continuing to rise or has already risen above electrical outlets, get out of the house and call emergency services for help. Do not return until it has been cleared by authorities.
Do not walk through the water if it has risen above electrical outlets, and there could be a live current running through the water, which could be deadly if you enter the water.
Turn off the electricity in your home if you can do so safely. This includes turning off the power to your furnace, water heater, and air conditioner.
If it is safe to walk through the water, do not walk through water without proper footwear, such as boots with good treads on them – this can be very dangerous and lead to injury. If possible, wear pants instead of shorts to avoid insect bites and skin infections.
Remove all valuable items from the flooded area and place them on high shelves or in other safe areas.

What are the Risks of Staying in a Flooded Home?

There are several risks associated with staying in a flooded home, including:

Electrical hazards

There is a risk of electric shock or fire if water comes into contact with electrical outlets or wiring.

Insect and rodent infestation

Floodwaters can bring about an increase in insect and rodent activity, which leads to a higher risk of disease transmission from these creatures.

Structural damage

A flood can cause structural damage such as cracks in the foundation or walls due to water pressure changes during flooding events. This can lead to the home becoming unsafe.

Mold and mildew

Excess moisture can cause mold and mildew growth, which can cause respiratory problems in individuals with allergies or asthma.

Gas appliances

If you have a gas appliance in your home and it has been flooded, there is a risk of fire or explosion due to leaking natural gas.

9 Rules for Electrical Equipment Safety After a Flood

If you choose to stay in a home with a flooded basement, be sure to follow these electrical safety rules:

Unplug all appliances and electronics

Removing electrical power minimizes the risk of electrical shock. Shut off the electricity if possible. If you see water or any other signs of damage in the fuse box or circuit breakers, do not go near these areas. Wait for an electrician to inspect them before trying to use them again.

Check for damage

Look for water or moisture in outlets, switches, and wiring. If you see any damage, have an electrician inspect the circuits before using them again.

Do not touch anything wet

Even if it does not look like it is live, do not touch anything that is wet. Electricity can travel through water, so it is best to avoid any contact.

Stay out of the basement

The risks associated with staying in a flooded home are much higher in the basement, so it is best to stay upstairs if possible.

Keep a flashlight handy

In case of a power outage, have a flashlight handy to help you navigate through your home.

Stay away from downed power lines

All downed power lines should be treated as live wires, so stay far away from them and do not touch them.

Check the sump pump

If your home has a sump pump, check to make sure it is working properly and has not been damaged by the floodwaters.

Bring in a generator

If you are able to do so, bring in a generator to power your home’s critical systems.

Wet vacuums should not be used in flooded areas

These machines can electrocute you if they come into contact with water or moisture. They should be used after the waters have subsided.

Can a Flooded Basement Cause Mold?

Yes, basement flooding can cause mold. Mold needs three things to grow: moisture, darkness, and organic material such as food, drywall, or wood.

Basements are often dark and damp, making them the perfect place for mold to thrive.

If you see any signs of mold in your basement, be sure to address them right away. Signs of mold include:

The Health Risks of a Basement Flood

A basement flood can increase the risk of health issues such as:

Respiratory problems

Mold and mildew growth in a flooded basement can cause respiratory problems for individuals with asthma or allergies.

The spread of bacteria and viruses

Floodwaters may contain bacteria or viruses that are harmful to humans, so it is best to avoid contact with them.

Structural damage

A flood can cause structural damage to a home, such as cracks in the foundation or walls. This can lead to the home becoming unsafe.

Insect and rodent infestation

Floodwaters can bring about an increase in insect and rodent activity, which leads to a higher risk of disease transmission from these creatures.

Contaminated water

Floodwaters may contain contaminants such as sewage or chemicals that are harmful to humans, so you should avoid them.

Carbon monoxide

If the floodwater enters your home, it may cause a buildup of carbon monoxide. This can be deadly if inhaled in large doses.

How to Prevent Mold After a Flooded Basement

There are several steps you can take to prevent mold after a flooded basement:

Remove excess moisture – Use dehumidifiers and fans to help dry the area.
Prevent water from entering your home – Check for leaks in pipes, roofs, and windows to prevent future floods from happening again.
Repair any damaged areas - If there are holes or cracks in the walls of your basement, be sure to repair them right away so that water does not leak into those areas again.
Clean up any debris or damaged items - Clearing out any debris and damaged items will help prevent mold growth in those areas of your home, which can lead to health problems for you and your family members.
