Banish Mold Infestations With Professional Help

How to take mildew out of concrete

What gets rid of black mold? Most of the cleaners weve mentioned can snuff out black mold infestations, but we recommend getting professional help for significant black mold growth. This is because Stachybotrys chartarum, or black mold, can be harmful if breathed in large quantities.

If a basement mold problem is really severe, mold removal specialists might turn to fumigation to eradicate the infestation. Whichever method they choose to take care of your mold problem, you can rest assured that a professional will do a thorough job to prevent the black mold areas from returning.

If you dont eradicate the source of the moisture that caused the mold, you could see more mold, but a professional will eradicate all mold spores and roots from an infestation so that the same colony cannot grow back, particularly in the same area.

Dehumidifiers and waterproofing paint can be useful for helping to stave off future mold issues. Wet, moldy surfaces like carpeting and drywall are often too far gone to be salvaged and need a replacement instead.

When mold is found in the interior of a home, its a much bigger deal because of the serious health hazards of black mold. For more extensive interior mold problems, it may be best to hire a professional mold mitigation service for removal.

If thats not in the budget or youve discovered the problem while its still relatively small, you can do it yourself.

Begin by protecting yourself. Because mold can affect the respiratory system, its best to use a high-quality respirator to block out mold spores. Also, use rubber gloves and goggles for eye protection.

Create either a bleach solution or a solution of detergent and water. The Environmental Protection Agency suggests the latter as detergent can better penetrate concretes porous surface than bleach.

For thorough cleaning, use trisodium phosphate, an industrial-grade detergent that will kill mold and remove grease and grime. Apply the cleaner with a brush and scrub thoroughly to remove the mold and engage the roots. Wipe clean.

Once clean, use a bleach or vinegar solution and allow the solution to dry on the wall or floor. This will serve as a preventative to keep the mold from returning.

Kill Mold Safely With Vinegar

One of the safest DIY cleaners for killing mold is vinegar. Vinegar is a mild acid that doesnt smell particularly pleasant, but it does its job with mildew. However, vinegar does not kill 100% of mold types, so do your research or test a small area before committing to it.

  • Baking soda and water solution

To clean mold with vinegar, liberally spray moldy areas with the undiluted white vinegar. Leave it on the moldy areas for at least an hour to penetrate and kill any roots embedded in the walls or floor.

Optionally, you may spray a solution of baking soda and water onto the vinegar-saturated areas to up its mold-killing power. Wipe down the surface with clean water to finish the job. White vinegar is an excellent , too!

If your basement smells like sewage, you may have a clog in the drain in the floor or in the toilet in the bathroom. Pour a mixture of vinegar, water, and baking soda into the drain to release the clog and quickly eliminate that sewage smell in the basement.

Repeat applications may be necessary if the clog does not break up the first time. However, after the clog clears, your basement will smell fresh and clean again.

Preventing Future Mold Growth

You should seal the concrete with a good-quality acrylic sealer designed for exterior use. Let the concrete dry at least 2 or 3 days in rain-free, sunny conditions before sealing. I recommend using a low-solids solvent-based sealer to allow for better breathability, especially considering the warm, humid exposure conditions. Read my article Driveway Sealer for Concrete to learn more about choosing and applying sealer.
