A mold growth that starts in the basement can easily spread to the rest of a home. And even if it doesn’t, the spores that it releases in your home will be just as dangerous. They can still trigger allergic reactions and cause severe respiratory complications in loved ones.

The good news is that mold in the basement can be fixed. This can be done by first fixing the underlying cause of excessive moisture in the basement, discarding mold-infested items, and then killing the existing mold.

Thereafter, taking preventative measures like installing a good dehumidifier, improving aeration by investing in a decent fan, and then routinely cleaning the area with mold-killing, will go a long way towards preventing a regrowth of mold in the basement.

Here is what you should know about fixing a mold problem in the basement.

Step 1: Discard items that have been heavily infested with mold

Items that feature extensive mold infestation are challenging to completely restore. This is so especially if you are dealing with rugs, mats, cardboards, and items made from mold-friendly materials. For such items, trying to simply restore them might end up leaving your basement with traces of mold. Therefore, discarding them is always advisable.

Step 2: Identify and fix leak sources

A leading cause of mold in basements is moisture leaks. This may result from plumbing leakages, condensation leaks from air conditioning units, and water seepage as a result of flooding or rainwater. Therefore, finding and fixing these leaks will go a long way towards fixing your mold problem.

Step 3: Invest in exhaust systems for cooking and showering areas

Steam from cooking areas and vapor from showering areas are a common contributor to high humidity in a home. This includes the basement. When you invest in good exhaust systems for these areas, you can get rid of the excess moisture before it has time to spread to the basement. Doing so will help to make your home less mold-friendly and it will thus help to keep your basement mold problem at bay.

Step 4: Improve air circulation in your home

Better air circulation reduces the odds of condensation. As a result, the chances of moisture settling on surfaces in the basement will reduce. And since mold loves surfaces that are moist or wet, this will help to stem your mold growth problem.

Therefore, investing in a fan is advisable. Making sure that you always leave your windows and doors open, especially after taking a shower or cooking, will also help.

Step 5: Install a good dehumidifier

Dehumidifiers are great at reducing humidity in homes. Installing a good one in your basement will reduce the overall moisture content in the basement and this will discourage mold growth.

Step 6: Avoid overcrowding items in the basement

Crowding reduces air circulation. It also tends to mean more surfaces on which mold can grow. Therefore, by reducing overcrowding, you will improve air movement in the basement, reduce opportunities for mold growth, and eventually fix your mold problem.

Can mold in the basement be completely removed?

Yes, mold in the basement can be completely removed. In order to do so effectively, one has to first remove items that have severe mold growth and discard them.

Thereafter, they have to scrape off mold from affected surfaces and then vacuum it with a vacuum that is fitted with a HEPA filter. They then have to soak the surface with a mold-killing solution like undiluted vinegar, diluted bleach, or commercial mold-killing solutions. Scrubbing the surface, applying more solution, and then wiping the surface to dry it should then follow.

Taking extra steps like installing a dehumidifier, investing in a good fan, and always opening doors and windows after taking showers, can go a long way towards keeping the mold from growing back. Some homeowners also find that occasionally spraying surfaces with mold-killing solutions helps to prevent mold regrowth.

3 Ways to get rid of mold in the basement

As a homeowner, you have several options as far as getting rid of mold in the basement is concerned. The following are the most common, and most effective, ways of ridding yourself of mold from the basement.

Use a sponge or a piece of dry clothing to get rid of any excess moisture and to speed up the drying process.
  3. Use commercial mold-killing solutions – A number of reputable companies manufacture mold-killing solutions that are specifically designed to kill and remove mold.

This is because mold usually releases spores. These spores get airborne, and when they do, they can travel to almost any part of a home.

What you need to keep in mind is that mold spores are the ones that cause skin irritation, eye irritation, respiratory complications, and all of the problems that come with a mold infestation. These spores are typically airborne, and when their concentration in the basement increases, the chances of the spores invading the upstairs increase.
