Can Mold Come Back After Remediation?

The short answer is yes.


Mold Spores Are Always Lurking

Even if the quality of the air is in pristine condition, mold spores are most likely present. There are five levels to mold growth and are normally not hazardous within the low levels. If the mold is at level one, (contained within a 10 square foot radius) you may be able to remove it yourself. However, there are steps you can take for complete eradication. Doing so will greatly diminish the chances of the mold returning.


You can greatly reduce the risk of mold coming back by using a mold remediation company that provides clearance testing. This testing ensures complete eradication and will leave you with peace of mind that the problem won’t return. If your mold remediation company missed anything or cut any corners, the clearance team will be able to tell and will demand these errors be corrected.


If you removed the mold yourself, a clearance test is even more necessary. Spending a few bucks so the mold doesn’t return will save money in the long run. A professional will be able to remove it safely and be able to verify it has been completely eradicated. Peace of mind is priceless when it comes to the safety of your home and the ones you love.


4 Questions to Ask Yourself After Mold Remediation


  1. How Does Mold Form in the First Place?

To keep mold from coming back you should know how it grows to prevent regrowth. There are three basic components that mold needs to thrive in; food source, moisture, and air. Mold reproduces through tiny spores that travel through the air and will multiply once it finds a moist surface. These pests like to nest in places you normally wouldn’t consider and are sometimes not visible to the naked eye.


  1. Do I Need To Complete A Clearance Test? 

If mold is growing the only way to know it is gone for good is a Clearance Test. This is why a Clearance Test is so important even if you trust the remediation company you are working with. If any of these things are present, mold will regrow-


  • Is there any visible fungal growth?
  • Is there moisture, debris, or dust still present?
  • Are the construction materials moisture free and within normal limits?
  • What is the fungal spore count in comparison to other areas in the home that were not affected by mold?


  1. Was the source of the moisture clearly defined and dealt with?

Where the moisture was coming from will determine if it will return. If the source is not found, you can’t be certain that the mold will not return. When the source of the moisture is discovered and resolved the mold can no longer thrive.


  1. Have You Taken Proper Precautions to Lower Chances of Mold Returning?


  • Check your pipes for leaks.
  • Keep the rooms in your home clean and keep the air in your home circulating.
  • Do not trust bleach to get rid of mold.

Bleach does not actually kill the spores on porous surfaces. The bleach remains on the surface level as the water travels inside the pores. This is just feeding the mold by adding more moisture to the mess! The chlorine in bleach can escape through plastic which is what they are packaged in. If your bleach cleaner isn’t brand new, it could be completely ineffective.

  • If something was ruined in flooding or damaged by mold, get rid of it!

Mold loves moisture so don’t keep things that could be potential homes for the spores.

  • Keep a dehumidifier in the basement or other damp areas.

Areas that are moisture-prone are also more mold-prone. Keeping these rooms dry might save you from mold infestations.

Oregano, cinnamon, thyme, tea tree, and clove are all awesome mold-fighting essential oils.
