Mold Remediation vs Removal: What’s the Difference?

Mold is a fungus that can be found in and around our homes. Once these spores latch themselves onto walls and ceilings they can spread at a rapid pace. The danger that a mold infestation holds for family members are devastating. Neglecting to get rid of the infestation can cause many health risks such as nasal stuffiness, wheezing, throat and eye irritation, and other respiratory issues.  For those suffering from asthma, the exposure to mold infested areas are even more dangerous. 

Many companies claim to remove all fungus and spores from properties, the truth is, in order for it to completely disappear from a home one should invest in mold remediation for a successful outcome. Qualified and experienced mold remediation companies will completely understand the science behind the spread and growth of these microscopic spores. 

A Little Bit About Mold: 

  • Spores are very small and can’t be seen with the naked eye. 
  • Spores are spread into homes through windows, the air conditioning system, or doors; they can get caught on your clothing and pet’s furry coat or float into the house with the wind. 
  • It can be found outdoors and indoors; it’s not confined to a specific space.
  • When exposed to moisture or water, mold can rapidly grow and turn into huge colonies. 
  • Colonies are grey, black, and brownish of color and are typically found on walls, ceilings, or floors. 
  • Moldy areas will have a musty, damp, and strong smell that leaves a horrible stench in a room that’s left untreated. 
  • When left untreated, colonies can cause hazardous health risks that has an effect on the respiratory system. 
  • Even after remediation, colonies can form again if the core moisture problem isn’t addressed.
  • Keeping your indoor space at a humidity level of below 45, will prevent colonies from growing back. 

When this fungus is completely understood, a company can assess the level of infestation and come up with a plan to remove it completely. Not just remove it, but also prevent it from growing back again. 

So, if both of these concepts are basically the same, what exactly is the difference between removal and remediation?


Even though these terms are used interchangeably by professionals, they mean two different things. Removal refers to only one part of an entire remediation process. It’s only used interchangeably when spoken to clients, because ‘removal’ is a much better understood concept by common folk. 

Remediation actually involves many different steps within the process that ensure all spores of the fungus are removed from the premises. These steps include: 

  • Assessing the area and identifying the severity of infestation
  • Communicating with the client
  • Containing and preparing the area for removal
  • Removing of the spores and colonies in the affected area (known as the ‘mold removal’ step)
  • Cleaning and sanitizing the area after removing of spores and colonies
  • Implementing other treatments that might include demolition of too heavily affected properties
  • Other preventative measures to avoid future growth and spread

As a customer, it’s important that you ask the company about the process they will be following. Asking about the process will clarify the steps that they will be taking. Whether it will be from the assessment through to the preventative measures or will they only be removing?

Before you hire a remediation company, you should consider the cleanup process that they will be following. As this will be the biggest indicator of whether it’s only removal or a complete remediation. 

Let’s take a closer look at the entire process step-by-step:

Step 1 – Identifying the Problem

It’s important for a mold remediation company to visit the affected premises first. Not only should the severity of the infestation be assessed but the cause of infection should be identified as well. 

In order for the removal, cleanup, and prevention steps to be successful, the problem should be properly addressed. This will ensure that, after removal, mold won’t return. 

Trained inspectors will use specific tools and measurement machines to assess the humidity levels within the property. If the problem is severe, teams might have to start breaking down walls or look behind building structures to find the source. This will only be done once the area has been properly prepped. 

Step 2 – Preparation and Containment

Before teams start to work it’s extremely important for the remediation company to contain the area. This is important for personal protection, safety of the environment, and preventing spores from becoming airborne and landing on other unaffected areas. 

Quality companies will typically use HEPA-filtered air filtration systems to ensure the environment stays unaffected, clean, and safe. Click here to learn more about how mold can affect you and your immediate environment.

Step 3 – Removal

To remove all fungus from the affected areas, professionals will use HEPA vacuums, and disposable materials. They will also surgically remove fungus and spores from buildings by demolishing it in a controlled manner. 

Other treatments might include the application of antimicrobial and a concentrated hydrogen peroxide mixture that help remove mold roots embedded within the structure’s walls. 

The removal process usually follows a specific protocol that should be followed by licensed companies. This ensures that the entire process is done safely. 

Step 4 – Prevention

To avoid future contamination and re-growth a professional will take necessary preventative measures. This will include removing the core problem and applying a mold-proof coating to the affected areas. 

Because the terms removal and remediation are used interchangeably in the industry, it’s important that you look at the finer details of the process before booking with a company. Don’t be fooled by thinking your fungus problem will be something of the past only because a company claimed to have removed it completely. Ensure that the service will follow all steps within the remediation process and you’ll have a guaranteed successful outcome.
