Can mold be completely removed from a house?

Hi, I’m Jeremy with SafeAir Certified Mold Inspection and I am a Certified Microbial Consultant. You can find me on the web at or you can also call me at 404-695-0673.

A question I am often asked is: Can mold be completely removed from a house?

There is some mold in every home. It is not possible to remove 100% of mold contaminants from the indoors. 

Also, mold spores from the outdoors find their way indoors through doors and windows and are part of the natural air quality. 

Even after a through mold remediation, there is always going to be some trace of mold contaminants leftover. 

After a successful mold remediation, mold levels indoors are brought back to a normal level.

We recommend having an air sample collected, by a professional mold inspector, in any indoor locations where mold remediation occurred as a measure of the success or failure of mold remediation. 

We recommend there be fewer than 800 allergenic type mold spores, per cubic meter of air, in an indoor air sample.

If you have remediated a mold problem to the best ability possible and you are still having issues with the indoor air quality, I recommend improving the filtration of the air in the home. 

This can be accomplished by installing a premium filter in the HVAC and operating the HVAC on fan continuously when heating and cooling is not desired. 

You will want to install a filter that is a minimum of a MERV 8 rating. A filter with a higher MERV rating, such as a MERV 11 will remove more mold spores from the air. 

You want to find out what MERV rated filters your HVAC will accept and install the highest MERV rated filter your HVAC will accept. HVAC filters can be purchased from the internet.

You can also work with your HVAC company on upgrading the filtration of your HVAC. HVACs can be retrofitted to accept much larger filtration systems than the standard HVAC will accept. 

This will remove the vast majority of mold spores in the air and cleans the air tremendously.

I had a premium air filtration system installed on my HVAC systems by Reliable Heating and Air. It was about $1500 dollars per HVAC after all of the bells and whistles. The air quality in my home is excellent. 

They had a more expensive upgrade that I wish I would have purchased. 

Your HVAC company will have options for improved filtration systems for your HVAC as well.

If you need a mold testing or just have questions, please call SafeAir Certified Mold Inspection for all of your mold testing and inspection needs.
