Smell Removal Solutions for Flooded Basement

 

1 Step 1: Fix Leak & Drain Basement

As a preliminary step, you will need to fix any water pipe leaks or water passages into the basement and drain the water out. In most cities, professional services can be hired to perform the task of pumping out all of the water level found within the basement’s space.

 
 

2 Step 2: Sun Dry Items & Baking Soda

Once you have the water pumped out of the basement, you will need to move out all items that have been affected by the flooding to dry out and deodorize within the sun. While the flooring is still moist, use an entire box of baking soda to sprinkle over the surface area of the basement’s flooring.

 
 

3 Step 3: Enzyme Cleaner or White Vinegar Wipedown

Once the entire area has been evacuated of flood affected items, proceed to wipe down all surface areas within the space with enzyme cleaner or white vinegar. Both of these deodorizing solutions will have the effect killing the mold spore that work to cause the dank mildew odor within the space. When using white vinegar, you will need to mix a solution of one part white vinegar with three parts water. You will need to apply either of these solutions while using a rag for the walls and a mop for the walls. Upon completion, it is smart to open the windows within the space and run one or two area fans within the basement to speed the drying process.

 

4 Step 4: Run Dehumidifier

If you notice that the basement might need something a bit more substantial than area fan to properly dry out the space, you may want to consider buy a dehumidifier. This machines will work to pull all of the available moisture out of the space and make it very difficult for mildew to grow within the space.

 
 

5 Optional: Ozone Machine

If a mildew odor remains after everything within the basement has been properly treated and dried out, you may want to consider renting an ozone machine. These machines are highly effective but also require precaution during their use. It is extremely important not to be with the space it is treating as it can be deadly within extreme cases.
