How to Remove Mold from Home?

Removing mold from your home can be a challenging task, but here are some steps you can take:

1. Identify and address the source of moisture:

Mold requires moisture to grow. Identifying and addressing the moisture source in your home is essential. This may include fixing leaks, improving ventilation, and reducing humidity levels.

  • Bathroom

In the bathroom, look for mold in the shower. Along the seals of the tub, behind the toilet, and under the sink. Don’t forget to look inside the cabinets close to these warm, wet places.

  • Kitchen 

In your kitchen, look around the sink and behind the fridge, dishwasher, and washing machine, all of which get wet. Check inside the cabinets, especially those that are close to pipes.

  • The attic and the cellar

Mold can grow in these places because they are not used or disturbed. Look around the water heater, vents, windows, and any stored items that could be a place for mold to grow. If your house has a crawl space, you should look for signs of decay.

  • Living Room and Bedrooms

Even though it is less likely, mold can still live behind furniture, on mattresses, and in stored clothes or blankets. Check the area around your windows, especially if you have central heating, because condensation on the windows can cause water to build up on the sills.

  • Clean up visible mold:

Use a solution of one part bleach to four parts water or a commercial mold cleaner to clean up the visible mold. Follow the steps outlined in the previous answer for cleaning mildew.

  • Remove moldy materials:

If mold has grown on porous materials such as drywall or carpeting, removing and replacing these materials may be necessary to remove the mold altogether.

  • Encapsulate surfaces:

Once the mold has been removed, you can encapsulate surfaces with a mold-resistant coating to prevent future growth. This may include painting or applying a sealant to surfaces such as walls or floors.

  • Maintain proper ventilation:

Ensure your home has adequate ventilation in bathrooms, kitchens, and basements. Use exhaust fans or open windows to improve airflow and reduce humidity levels.

  • Regular cleaning and maintenance:

Regularly clean and maintain your home to prevent moisture and mold growth buildup. This includes periodically cleaning bathrooms and kitchens, using a dehumidifier in high-humidity areas, and addressing leaks or water damage.

  • Fix the plumbing leaks and other water issues quickly. Find the source of the mold. 

Removing mold requires identifying and addressing the source of moisture, thorough cleaning, and ongoing maintenance. Suppose the mold growth is extensive, or you are unsure how to proceed. Consulting with a professional mold remediation service may be necessary in that case. If you have not located the mold sources, contact a professional if you think it is hiding below the wallpaper and are afraid that eliminating it will lead to spore release.
