basics of mold removal


Basic Overview of the Mold Remediation Process.


The phrase mold remediation is loosely defined as a collaborative process to kill mold. Mold encapsulation is the process of containing mold within a mold resistant polymer.

However, mold encapsulation can also be used in the absence of visible mold. It may be applied to surfaces where visible mold growth occured, to encapsulate mold spores. These encapsulants are propylene based polymers that react to form an elastic, mold proof seal over walls. This seal will resist moisture, mold, mildew and bacteria when properly applied.


How the mold removal process begins:


1) All HVAC systems and noncontaminated areas must be sealed off from contaminated areas. When mold is disturbed, under magnification, it releases millions of spores. If you’ve ever mowed over a mushroom on your lawn before, you can witness this basic process with large fungi such as mushrooms. Don’t forget that mold is a spungi afterall.


2) Once all areas are sealed, the mold should be powerbrushed with brass bristles. Not all areas need to be powerbrushed, only areas that have been extensively decayed by mold growth.

3) A non corrossive, non toxic , nanobased moldicide must be applied with an airless sprayer. This is for maximum penetration. Once sprayed, all areas should be left to dry for 1 hour. If you must use fans to rush the process, they absolutely must utilize HEPA filters.

4) Once all areas are dried, they should be sprayed with a safe, nanobased mold encapsulant. Certain water based encapsulants are extremely thick and may need to be diluted with water. This will depend mostly on your airless sprayer and its PSI rating.

5) After encapsulation is complete, all contained areas must be HEPA vaccumed to remove any residual more spores. This may seem like overkill to a lot of people, but we have witnessed first hand what can happen when this is not done. We have also witnessed the staggering amounts of mold spores that are released into the air anytime its disturbed. It looks like a small hurricane of mold spores landing on every surface of the contained area. This is why HEPA vaccuming should always be done at the end of the mold remediation process.


Additional information about treating mold:


As a customer, you need to ask questions and examine the mold inspector as he examines your home. There are no regulations for treating mold in New Jersey or any other state.

This is because there are more than 30 million different strains of mold and it would take a lot of money, work and resources for the government to set any kind of regulations for all these different strains.


Also, please be careful and pay attention to what the mold inspector is focused on.


We have noticed this problem in NJ where companies come out and don’t really inspect a home. They may walk around and pretend to do an inspection. They may espouse a few technical facts and try to impress you with the most basic knowledge about mold. But they will very quickly get on the topic of mold testing. And they will both overemphasize and exaggerate it uses. They will make statements like, “we really can’t evaluate your home any further unless air sampling is done”.


98% of the time mold testing is done wrong so should it be done at all? 


If you are selling your home, then yes, it should be done. The home buyer will likely want to see post test results and know that the spore count came down beneath threshold levels.

The problem is, mold testing by nature is wildly inaccurate. We do employ it in our own practice, but most companies will not explain all the factors and triggers that can result in false positives. It happens so often in this industry and people wind up paying hundreds if not thousands for mold testing that does not need to be done.

Remember, the main goal here is to quarantine, kill, shield and secure all contaminated areas. An experienced company knows how to do this without any sampling. The main problem with air sampling (mold testing) is just opening your door or window on a windy day can allow in millions of spores and throw your count far over thresholds. This is taught in any basic microbiology class or mold training course.


The real way to do mold testing and establish accurate values, is to come back to a property once a week, week after week, then calculate averages until you get them within a controlled range?


Yes, in fact – this is the only way to eliminate outliers & false positives. It’s almost like testing blood sugar just a lot more expensive. The more and more testing that is done, the more and more you realize how statistically insignificant 2 or 3 sets of mold tests are. You will gain some valuable insight but it will still be just the tip of the iceberg. And that is the exact problem. So many companies run just 1 set of mold tests on 1 day at 1 particular time but will never explain to you in statistical terms, how insignificant the results are going to be.

They are highly insignificant.

When selling a home, these values are provided merely as a smoke screen to appease the buyer and get them off your back. That is the cold hard truth. Because there is no way the homeowner or agent will want to open up this can of worms. It’s impossible to explain to home buyer, “look, our company (MMRG) has been through this a thousand times before and you just need to take us on our word – the levels are safe”.

We’ve had buyers challenge us many times and it always ends the same. The homeowner spends thousands of dollars for mold testing just so we can say “it’s safe”. When our company already knew that cause we know how mold grows but more importantly how it doesn’t grow. We know beyond a reasonable doubt that the conditions would be completely unviable for mold to recolonize in any area after we have treated it.
