10 Easy Steps on How to Get Smell Out of Basement After Flood

Follow these steps, and you should be able to restore your space to its former glory in no time at all.

1. Open Windows:

The first step is to open windows around the basement to increase air circulation and allow fresh air to enter. This will help remove odors from the room naturally. Additionally, this will help to reduce humidity levels which can also cause odors.

2. Turn on Fans:

Next, turn on fans in the room to further aid with odor removal. This will also help to reduce humidity levels, making it less hospitable for germs and bacteria that cause bad smells. Don’t forget to open the windows when using fans and ensure that it is running continuously for at least half an hour.

3. Use a Dehumidifier:

If you have a dehumidifier available, use it as well to reduce moisture levels in the room, which can be a breeding ground for unwanted odors. Try to keep the dehumidifier running for at least a few hours each day. Because the room may still be damp even after using a dehumidifier, it can also be beneficial to use an air conditioner.

4. Clean All Surfaces:

Use cleaning products such as bleach or white vinegar and water solution to clean all surfaces of the basement, such as walls and flooring. This will help remove any trapped odors. Moreover, a vacuum cleaner can suck away any trapped moisture in carpets or furniture.

5. Soft Vacuum Furnishings:

If you have carpets or soft furnishings in the basement, use a vacuum cleaner to remove any trapped moisture which can cause bad smells. You can also use baking soda to absorb any odors that remain. Be careful not to leave the baking soda in place for too long, as it can cause damage to fabrics.

6. Clean Out Drains and Pipes:

To prevent bad smells from entering the room through drains and pipes, clean them out thoroughly using a cleaning solution or vinegar and water mixture. Apply the solution to the inside of the pipes and drains and leave for around 10 minutes before rinsing off with hot water. Ensure all the drains are completely dry before closing them up.

7. Place Odor Neutralizers Around the Room:

There are certain odor-neutralizing products that can be used to help get rid of lingering odors in the room, such as baking soda or activated charcoal bags. Place these around the room to help eliminate odors. Be careful not to leave them in place for too long as they can be damaging if left for too long.

8. Place Fresh Bedding and Towels:

Using fresh bedding, towels, and blankets can help to absorb any remaining odors in the basement. Change them every few days until all unwanted smells have been removed. If you have pets, make sure to wash their bedding frequently in order to get rid of any lingering odors.

9. Sprinkle the Carpet with Odor Neutralizers:

If you have carpets in the basement, sprinkle some odor neutralizing products such as baking soda or activated charcoal onto them before vacuuming them up. This will help to remove any trapped odors from the carpet fibers. Another option is to use a carpet shampooer, but make sure that the room is completely dry first.

10. Use Air Fresheners:

Finally, use air fresheners around the room to keep your basement smelling fresh. Make sure to change them regularly to keep the odor at bay! Because flooding can often cause mold and mildew to form, it’s important to tackle any issues with these first. Be sure to use a professional service to help you with this if necessary.

By following these simple steps, you should be able to easily get rid of any unpleasant smells from your basement after a flood. With patience and persistence, you will soon have your space smelling fresh and clean again!

5 Additional Tips and Tricks

1. If the smell persists, consider investing in a wet-dry vacuum. This can help suck out any moisture left in the air and on surfaces, thus helping to remove the odor-causing bacteria.

2. Investing in an air purifier or dehumidifier can also help reduce the smell in your basement after a flood. Both of these machines work by removing moisture from the air and preventing it from condensing into the walls and floors, which is how odors are created.

3. Consider installing a sump pump in your basement to minimize future flooding. This will help ensure that any water that accumulates during heavy rains is pumped out quickly before it has a chance to cause serious damage to your home, as well as to emit unpleasant odors.

4. Clean all affected surfaces with a bleach solution to kill any lingering bacteria or mold spores that could be causing the smell. Be sure to use a diluted bleach solution, as full-strength bleach can damage some surfaces.

5. Set up fans in your basement to help circulate the air and get rid of any odors that may remain after cleaning. The fans will also help dry out any still dampness, thus helping to prevent mold growth and further odor issues.

With regular use, you’ll soon have a smell-free basement!

5 Things You Should Avoid

1. Avoid using any cleaning product that has a strong scent. After a flood, the smell of chemicals in the air can further pollute the air and make it difficult to get rid of the musty odor.

2. Don’t use bleach or ammonia-based cleaners. Both can be damaging to your basement walls and floors, as well as irritating to your nose and eyes.

3. Avoid storing anything that could attract bugs or rodents in your basement until you have thoroughly cleaned and deodorized it.

4. Don’t leave wet items such as rugs, clothing, or furniture in the basement for too long; mold will begin to form quickly if left unchecked.

5. Don’t forget to open windows regularly and let fresh air into the basement. This will help to remove any lingering smells and prevent musty odors from settling in.

Do Not Forget to Open Windows Regularly

With a few simple steps, you can get rid of the musty odor in your basement after a flood. Be sure to take safety precautions when cleaning up and to deodorize your basement, and avoid taking any actions that may worsen the smell or cause further damage to the area.


To conclude, proper ventilation is the key to getting rid of stale and musty odors in basements after a flood. If you could open windows or install a fan to draw fresh air in and push out bad air, that would do wonders for improving air quality and smell. Alternatively, if that’s impossible, you can use activated charcoal or cat litter to absorb odor molecules and keep them from circulating around your home.

If none of these solutions are viable, you may want to try using a dehumidifier or invest in an ozone generator for more serious problems. All in all, it’s important to keep up with basic maintenance like cleaning and sanitizing surfaces and ensure there is no standing water before taking on any long-term solutions. The most important thing is to take action before the smell gets too offensive and spreads throughout your dwelling.

Hopefully, the article on how to get smell out of basement after flood has been helpful in teaching how to properly and safely get rid of the odor. With a few simple steps, your basement will be smelling fresher than ever!
