When Is Mold Remediation Required?

Share This Post

We don’t always need Mold Remediation. But mostly, remediation depends on prevailing
conditions such as flooding or when there is a severe decline in air quality. Sometimes the need
for mold remediation is determined through inspection and testing done by the occupant or a
hired mold inspector.

Or in other instances, it could happen upon recommendation by a public health officer. In this
article, we discuss three scenarios when remediation is inevitable.

During Post-Flood
Floods can be devastating. Dealing with post-flood damages is quite overwhelming too. But with
the right know-how, it is possible to get things back to normal quickly and safely.

It is pertinent to know how to deal with molds during emergencies such as floods. To understand
how to tackle the mold problem, you must understand the morphology of fungi.

Molds spores germinate within 48 hours, and that means you need to act fast. Getting the
building dry must happen as quickly as possible.

As you drain all moisture, consider all the cavities and walls. Do a thorough mopping of all
areas, including the doors, cabinets, and closets.

To dry up all moisture, use dehumidifiers and fans. By employing this technique, you draw
moisture through air circulation.

Tip: Disconnect electrical cables to avoid the risk of electric shock when draining soaked rooms.

After 48 hours, mold remediation becomes a complex activity. Mold begins to grow fast in
hidden areas, posing a health risk to you and other occupants of the building.

Cleaning hidden areas like in cushions or under the carpets require expert intervention. As the
situation develops, it becomes difficult and dangerous.

Wearing Personal Protective Equipment (PPEs) becomes critical as the risk increases. And if you
are not in a position to remove mold by yourself, then seek help from a certified mold

Here are PPEs necessary for mold remediation in flooded environments:

● Rubber boots
● Gowns
● Face shields
● Masks
● Goggles
● N-95 respirators or similar alternatives
● Latex gloves

Remember, by using PPEs, you protect yourself from other risks like bacteria and other toxic

Assessing the damage post-flood helps in knowing whether the repair will work or a complete
tear-out/replacement is required.

While repairing, raise the boards to at least 2 feet from the ground. Also, watch out for asbestos
and lead components present in housing built before the 1980s.

Always clean surfaces using water and detergents. Avoid mixing bleach and ammonia or other
incompatible products as they produce toxic fumes.

When air quality declines

Dust is the first culprit that affects overall air quality in any environment. The particulate matter
is something we cannot run away from as far as mold growth is concerned.

There are various ways that dust forms. It can be as a result of chemical gases reacting in the air,
from combustion processes in industries or as a result of mechanical action like during soil
erosion or mining.

Dust movement is dependent on wind direction and speed. Even in less windy areas, dust
particles accumulate slowly, and the effect is seen in our homes.

You will find dust settling beneath shelves, cupboards, or in wardrobes. If left unchecked, that
creates perfect breeding for molds.

When left uncleaned, dust moves to upper surfaces as most dust particles defy gravity. With
humidity and oxygen, mold spores begin to contaminate the air in your indoor environment.

Mold spores are microscopic. They contain allergens that are toxic and irritating. As they
continue to fill the air space, the health risk of occupants becomes a vital issue.

Long term exposure to dust containing mold puts your health at risk. It exacerbates conditions
like hay fever, allergies, and asthma.

With declined air quality, mold remediation is the ultimate solution. Negative air containment is
the best way to eradicate mold in a stuffy environment.

Recommendation by Public Health Officer
The US lacks regulations governing mold remediation activities. However, the Environmental
Protection Agency provides guidelines for conducting mold remediation in schools and
commercial buildings.

A Public Health Officer is a critical human resource for disseminating information on air quality,
focusing on dampness and molds. These officers have the authority to conduct site visits and
make recommendations on mold remediation.

In New Hampshire, tenants must conduct a proper inspection of essential things that include
molds. They should report any cases of mold growth to the landlord before moving into the

Once tenants notify the landlord, the landlord will then plan an immediate mold remediation
exercise. To be sure, check landlord-tenant laws in your state.

So far, few states have made strides in putting in place regulations and standards governing mold
remediation. States like Maryland, California, Texas, New Jersey, and Indiana have standards on
permissible mold levels.

When mold is detected by testing

You can test for molds on your own or invite a mold inspector to do a professional job for you.
Testing determines the need for mold remediation.

However, it is worth noting that testing is not necessary as molds get removed anyway. Also,
there is no standard for acceptable levels of mold.

Testing is expensive too! But when conducted, it informs the next steps for mold remediation.

So, why is testing necessary?

● It analyzes the toxicity of molds. Some molds are harmful while others aren’t, and that
helps in understanding how to handle the molds.
● It helps you understand the source and reasons for more growth
● Testing helps to scientifically understand the nature of the environment one is living in

● It also helps to know the air quality index that informs safety

Mold testing achieves great results when preceded by physical inspections. When a certified
mold inspector visits, they can reveal the extent of mold growth, thus recommending proper
steps for mold remediation.


We can note that inspection and testing inform the need for mold remediation. It lays bare the
mold situation based on Science. In the case of commercial buildings and schools, mold
remediations happen upon recommendation by a public health officer. Circumstances could also
lead to mold remediation, for example, when there is flooding or when the air quality is
significantly affected.
