Every company claims to offer the best solution for resolving a mold issue.  While there is a variety of outcomes for every method, on average, one has to perform better than the rest.  But which is it?

 Complete demolition and physical removal, followed by reconstruction is the oldest method. It gets rid of the bulk of the mold growth and spores like all methods do, but it doesn’t treat the air and disturbs and spreads mold spores in the process. Scrubbing has the same effect as demolition, and shares the weakness of limited surface area treated and higher labor costs.  Ozone would be amazing if it was safe to use the concentrations needed to do a proper job.  The proper concentrations of ozone would be extremely toxic, and mean vacating your home for a longer period of time. That said, it does a decent job.  Wet fog or ULV (Ultra Low Volume) is also pretty good, but its average droplet size of ~17 microns is incapable of reaching mold hidden in pockets and gaps as well as our dry fog can which has droplet size of 7 microns.  It also doesn’t dwell in the air for a sufficient amount of time to ensure airborne spores are killed.   UV light is the last approach, which is great for all the areas that the light is able to reach. 

The common measure for efficacy is volume and surface area treated. The more of both that you treat, the better the end result. Dry fog is the clear winner.
