Remove the Water

If the flooding in your basement was caused by heavy rainfall or a natural disaster, you can start removing it straight away. If it was caused by one of the aforementioned issues, it may be best to stop or fix the cause before you get to it, depending on the issue. For instance, if there is a huge pipe leak, trying to remove the water first is likely to be futile.

If you want to get rid of the water quickly and efficiently, use a submersible pump. You can also use a wet-dry vacuum. If these are not an option, you will have to bail out the water the old-fashioned way—with buckets.

No matter what method you use, make sure to dump the water as far as you can from the foundation. To remove as much moisture as possible, open the windows and set up some fans or use a dehumidifier.

Commercial dehumidifiers or air movers are the best solutions, so try to rent one if possible. It may take 1 to 3 days to completely dry the basement. Get to this task as quickly as you can. If you wait for too long, mold may appear.

Salvage What You Can

Try to rescue what you can. If the flooding is huge, you will most likely have to come to terms with the fact that you can’t save everything, so focus on electronics, important documents, and family keepsakes.

You need to properly dry the belongings you want to salvage. Unfortunately, you will have to throw out some of the damaged items.

Paper items, insulation, carpeting, and carpet padding are most susceptible to water damage. It is best to replace these items with new ones. To dispose of damaged items, it is best to use heavy-duty plastic bags.

You may need to remove the drywall as well. This depends on how long the water sat in your basement and how heavy the flooding was.

Disinfect and Deodorize

Once everything is dry and you have removed everything, you need to disinfect the basement and the salvaged items. This will prevent the growth of bacteria and mold.

It’s best to create your own bleach solution that you will use as a disinfectant. Pour a cup and a quarter of bleach in one gallon of water, give it a mix, and spray it on hard surfaces. Use a hospital-grade, color-safe disinfectant on fabrics.

Sprinkle a bit of baking soda on the fabrics in order to prevent unwanted odors. Let it sit overnight and vacuum it the next day. You may need to repeat this step.


Basement floods and leaks require quick action. To successfully deal with water damage, you need to know what signs to look for and where to look for them. It’s also good to know who to call for help in such situations.

If the water damage in your basement was caused by extensive flooding, you may be able to deal with the aftermath on your own. If the damage is too big, however, it may be best to hire a professional flood restoration damage crew.
