The Need For Moldy Basement Solutions

Some might think that having a moldy basement isn’t a crisis, but it is!

The mold spores travel in the air and can affect those who have respiratory issues like asthma. They can also cause allergies when contact is made with the skin.

To add to that, mold growth destroys the aesthetic appeal of your home, and this would surely reduce the face value of the property if you ever put it up for sale.

Last but not least, mold smells pretty bad, and this would deter you from spending the desired time in your basement, which took you so much time and effort to furnish.

To sum it all up, a healthier environment, the better market value for your property, and sweet-smelling air are among the 3 major reasons you should get rid of mold from your basement walls, ceilings, and floors.

Preparing The Area For Basement Mold Cleaning

Getting rid of mold from all over your basement requires the use of a cleaning solution, so you should expect some splashes here and there. This is why you need to prepare the area first before you clean.

The first thing you should do is take out all the moveable furniture so they don’t get dampened by the splashing liquid. Also, take out anything that could obstruct the work, these include hanging pictures, jackets on a coat rack, etc.

You should also get a broom and sweep the walls so they can be free of dust and debris. Do the same for the ceiling to rid it of obstructions like cobwebs.

It’ll be a good idea to open the basement windows while you clean, as this would allow good airflow. Remember, mold has a musty smell, some inflow of air would make the process less discomforting.

Once you’ve cleared out the workspace and cleaned the surfaces, you can begin getting rid of the mold.

Protecting Yourself From Black And White Basement Mold

Mold spores aren’t something you’d want to get in your eyes or mouth, and mold itself isn’t something you’d like to touch with your bare fingers. This is why you must protect yourself while getting rid of them.

Put on a pair of gloves to keep your fingers from touching the mold, and put on protective goggles to keep mold spores or other cleaning agents from flying into your eyes.

You should also put on a facemask to protect your mouth and nose.

Now you’re all set to begin, let’s start with the ceiling!

How To Get Rid Of Mold On Basement Ceiling

If there’s mold all over your basement, then removal should start from top to bottom. This means you should begin cleaning from the ceiling, then work your way down to the floor.

This is the wise thing to do like water and any cleaning solution you will use flows downwards.

Here are the things you need to get rid of mold on your basement ceiling

  • Cleaning solution (made with either baking soda, vinegar, tea tree oil, bleach)
  • A hard brush (or extension brush)
  • A ladder
  • A spray bottle
  • A clean, dry cloth

To begin, make a solution using either vinegar, tea tree oil, or bleach. Be warned though, do not mix any of these substances with other cleaning agents, as that can cause the production of toxic fumes.

Instead, mix with only water to create your basement mold removal solution. After you have mixed the household mold cleaning agent with water in the right parts, pour the solution in a spray bottle and apply it across the infested ceiling.

Leave the solution to sit for 30 minutes to an hour, then climb up the ladder with your hard brush the scrub the loosened mold off the ceiling. If you’re not a fan of climbing, then a long-handled brush will do.

You can splash some water across the ceiling to take off the remaining mold debris, then dry it off with a clean towel. You can spray the ceiling with the solution once more as a preventive measure.

How To Clean Mold From Basement Walls

After you are done with the ceiling, you can then move down to the walls. Using the same cleaning solution, spray across the infested walls until you have covered all the spaces.

Remember to make a large enough batch that will be able to handle all three areas (ceiling, walls, and floor). Make another batch if need be.

After spraying the walls, use the hard-bristled brush to scrub the annoying mold off. You will have to put in some energy as you scrub so you can really loosen them up.

When you’re done, be sure to wipe with a dry towel. If you’ve still got some mold on the wall after this, you can repeat the process until all the mold on the wall has disappeared.

As a preventive measure, be sure to spray the solution on the wall one more time, then leave it to dry on its own without wiping with a cloth.

How To Get Rid Of Mold On Basement Floors

So, your ceiling and walls have been wiped free of mold, all that’s left to do is the floor. Hopefully, you made a solution batch that’s enough to handle the floor.

You should’ve also removed the carpet from the basement floor before you begin cleaning.

Now take your brush and dip into the solution, then scrub the floor as hard as you can to dislodge the mold. Make sure you get all the spots where mold is growing.

If you don’t, even the smallest amount of mold left behind can begin to grow again.

It doesn’t take long for mold to build up, 24 to 48 hours is all it needs under the right conditions.

When you’re done scrubbing the floors, use a mop to dry it up. This will help you pick up loose mold that’s left behind. You can follow up with a vacuum cleaner to pick up any bits and pieces of mold that were lucky to escape the first time.

You can now re-spray the floor with the solution and leave it to dry on its own.

If the carpet you took outside has also been infested with mold, then you can scrub it using a bleach or vinegar solution. Spread it on a line so that it can dry from the sun’s heat.

The UV rays will also kill any mold growth on the carpet.

Make sure it is 100% dry before you bring it back inside. If it’s not totally dry, then it’ll be damp and will attract mold growth once more. You don’t want to deal with the same issue twice do you?

Killing Mold In Basements

Many commercial mold removal products in the market can also kill mold. However, most products of this nature are toxic and can be harmful to humans and pets if not handled with care.

How To Remove Mold From Brick Basement Walls

Brick is pretty tough, but it can still be porous. This means it can also absorb moisture, which also means mold can grow within it and not just on the surface.

The same method of mold removal from basement walls explained above can be used to get rid of mold from brick basement walls, but you have to ensure the solution you use can penetrate its pores to get to the internal mold and kill it.

In this instance, using a vinegar solution will be ideal, since it’s already in liquid form and can easily be absorbed.

Solutions made with powdery cleaners are great, but the dissolved powder may not go into the brick walls as deep as you would like.

If you must use a powder cleaner, then ensure that it is properly dissolved to stand a better chance of penetrating the pores of the brick wall.
