We Practice The Area’s Best Mold Containment.
Should You Care?

Mold May Not Be Able To Grow In Dry Areas Of Your Home…
But Mold Itself Isn’t What You Should Worry About.


When I explain my company’s meticulousmold containment process to homeowners in Northern VA, Central VA, and Washington DC, I typically get one of two reactions…

  1. “Wow, that’s amazing! You really take the time to do things right!”
  2. “… who cares?”

Homeowners in the “that’s amazing” crowd may not always understand all the science behind proper mold containment. But they trust the process. 

The “who cares” crowd is a little different—and I completely get where they’re coming from.

They don’t see why it matters if mold spores move from the project area to other parts of the home if those areas are dry. After all, if mold spores don’t have moisture, they can’t grow into a mold colony. So what’s the harm?

The logic seems sound. But it’s not actual mold you have to worry about.

It’s mold spores.

The Dangers Of Mold Spores

You inhale mold spores with every breath you take. 

You just inhaled some reading that last sentence. 

And you’re now inhaling more as you read this sentence.

Breathing in mold spores in small amounts like this won’t affect the average person. But breathing in the massive number of airborne mold spores caused by remediation? 

That’s a different story.

When you remove or disturb a mold colony, it releases billions of spores into the air to take root somewhere else more friendly. And breathing in this large amount of mold spores is not good. 

There are two harmful part of a mold spore:

  1. The mold spore itself. Of the people who have a health reaction to mold, roughly 90% have an allergic reaction to the mold spore, mold colony, or mold fragments themselves. So breathing in a spore causes an allergic reaction.

Some people think chemicals will save the day but it doesn’t matter: 

If you spray it with a chemical that breaks down the spore into a million pieces—now you have a million more pieces that cause a health reaction. 

If you “kill” the mold with chemicals, now the spore can’t grow into a colony if it lands on a wet surface…but it still causes the same allergic health reaction to you personally.

  1. Mycotoxins. This is a secondary metabolite that fungi like mold naturally produce. A mold colony uses them to fight other colonies for food. Mycotoxins can cause ailments ranging from minor allergic reactions to asthma to life-threatening illnesses. The more mycotoxin you’re exposed to, the bigger the health risk.

Other harmful components of mold are fungal fragments (pieces of the mold colony that have broken into even smaller fragments), beta glucans, mVOC’s (microbial volatile organic compounds), and so on. These are all things you want to avoid behind exposed to if you can help it

Long story short…

Thinking of inhaling mold spores like drinking wine. Consuming a small amount at a time won’t harm the average person. Drinking 10 bottles at a time? That’s a health hazard to anyone.

Why Mold Containment Is Critical: The “Dandelion” Effect

When you kick a “fluffy” dandelion, it releases dozens of its seeds into the air. Mold colonies act much the same way as dandelions… except on a massive scale. 

When a mold remediator is working, he or she disturbs the mold colony. As I mentioned a moment ago, this causes the colony to release hundreds of thousands of mold spores into the air. If the project area isn’t properly contained, those mold spores will spread to the rest of your home

This is why we’re so meticulous with our containment process. 

We go to extraordinary lengths to prevent mold spores from escaping the project area and permeating other areas of your household. If a mold remediator doesn’t do this, the entire project is pointless.

It’s that simple.

But Proper Containment Is More Than Just A Barrier…

A company could have a painstaking containment process. They could meticulously erect the highest-quality barrier. They could use the greatest materials on the market.

And none of it will matter at all if they don’t utilize the Air Filtration Device (AFD) set up as a Negative Air Machine (NAM) during the removal process. 

The truth is that even the best containment barrier on the planet is not airtight. 


  • Spores can float into other areas of your house after walls or ceilings are cut open.
  • The mold remediator has to enter and exit the containment area several times via the zippered entryway.
  • Small gaps in the containment barrier are inevitable. 

If the contained area isn’t under negative air pressure, these “vulnerability” points will let mold spores slip through and cause cross-contamination (i.e., other parts of your house that didn’t have a problem before, now have high amounts of mold spores). 

That’s why Proper Containment + Negative Air Pressure is the proper equation during the demolition and mold-removal phase. I break it all down in this article: How Most Mold Remediators Botch Air Pressure [blog post: “How Most Mold Remediators In NOVA, Central VA & DC Botch Air Pressure].

Bottom Line: We Contain Mold RIGHT

If you’re in the “who cares” crowd I mentioned at the beginning of this article, I hope I’ve shed a little light on why containment is so important. It’s one of the most critical aspects of mold remediation… and it can make or break your entire project.
