Does dry fogging eliminate mold? The short answer is no. Dry fogging does not eliminate mold by itself. It is a low-cost, band aid solution to your mold problem. On the surface it may appear that it worked, but in reality it’s only removing the surface mold, leaving behind an expansive root system. Let’s dig deeper into this.

Reasons Why you shouldn’t only use dry fogging to eliminate mold 

1. Dry fogging alone does not take into consideration what the true cause of the water or moisture intrusion that led to your mold growth in the first place. A source of water, humidity, or moisture had to first take place before the conditions are met where mold can grow. Dry fogging only addresses what’s on the surface of the home, and by doing so, you are neglecting to identify and correct the source of intrusion.

2. Mold has hyphae which are a roots-like system that physically grow into porous building materials such as drywall or insulation. So when you use a dry fogging for mold remediation strategy, you’re simply not removing the hyphae from the building material.

Put simply, mold will grow back again. The low cost of dry fogging mold removal may seem attractive, it isn’t money well spent when the mold comes back. 

Almost every dry fogging mold remediation company out there will recommend you have your home on an ongoing treatment plan. They know their solution is a band-aid and want the re-occurring revenue from you as a customer when you have the dry fogging process performed again in the future.

Correcting the source of the problem may seem more expensive upfront but it will save you a lot of time, money, and energy in the long run once the problem is resolved. Always remember the following quote:

“The bitterness of poor quality often remains long after the sweetness of low price is forgotten.”

3. The process of dry fogging will never be able to “penetrate” walls or ceilings and eradicate mold colonies that are often growing behind the surfaces. Without addressing the cause of the problem and the structural degradation that often accompanies the presence of mold, the structure will continue to degrade and mold will continue to colonize behind the walls or ceilings that are being “treated”.

Proper use of dry fogging in mold remediation 

Fogging is what we would call “Phase 2” of remediation where you clean up the surfaces of the home to remove any contamination that was created by the sources of mold.

This is only something that should be embarked on after “Phase 1” is completed by removing the sources of mold creating the contamination, and correcting the conditions that led to the mold sources growing in the first place. If you do “Phase 2” of remediation without first doing “Phase 1” of remediation, you’ll end up having to reinvest in both phases again, in the proper sequence, which will result in money wasted on trying to do demolition-free remediation first.

So while fogging is a very useful part of mold remediation, be weary of any claim that dry fogging alone will eliminate mold.
