Mold Education

Please allow yourself a few minutes to read this valuable information before you spend your money on a mold inspection, it could save you many headaches and a lot of money. A lot of information is false and exaggerated regarding mold.  

Don't be confused. It's all about the air we breathe.

(as well as the value of your real estate)


Most Americans spend 90% of their time indoors, and most of that time is spent either at home or at work. It is a fact that mold spores can enter our bodies through skin, eye and mouth contact. In the truest sense, mold primarily becomes a problem when the air we breathe becomes saturated with amplified levels of mold spores.


Mold growth (colonization) occurs when water leaks or water intrusions occur causing mold spores to become airborne. Whether at home, work or school, airborne mold spores can affect our health.


Those most affected by mold are:

  • Children

  • Elderly

  • People with allergy or asthma conditions

  • People with a compromised immune system from a disease, surgery or other health problem


Excessive moisture is the culprit and mold is the result.

When mold colonizes indoors it releases spores which become airborne, just as though it was outdoors. However, when trapped by indoor containments, the airborne spores have nowhere to go. As a result, much like smoke in a closed room, the air becomes densely filled with toxic mold spores, forcing mega-doses to be ingested by anyone who occupies the environment. Performing a mold inspection and taking an air sample will reveal air quality conditions.

Stop the moisture source first. Then clean up the mold.

Create a dry and more efficiently ventilated indoor environment or the situation will only continue to get worse. Mold spores are present naturally on most every surface. Mold spores simply wait for water to begin colonizing. It can be a simple elevation of humidity, not just actual visible water. Although we can never get rid of mold completely, we can control it.   


Inspect for mold & water intrusions and test the air.

The only way to know what is in the air is to take samples. People can spend a lot of time and money cleaning mold conditions which pose no direct or potential health threat. A formal water intrusion and mold inspection will reveal current and potential water intrusions and mold colonization. 


Air sampling and mold testing should reveal any amplified levels of airborne mold spores, and hopefully the source of the mold spore contamination. Lab analysis will determine the types of mold and the total mold spore counts present. It will also help to determine what further actions may be appropriate.

Why are you here?

If you think you have a mold problem, find a category below that fits your situation.


Buying a home

Make sure you are not purchasing a mold problem! You could be faced with significant expense cleaning up a mold problem that was not discovered during the time of purchase. An unknown mold problem could exist. Mold inspection and mold testing will provide the actual conditions.


Selling a home

Make sure you are not selling a mold problem. "Ignorance is bliss" as they say, but lack of knowledge does not relieve liability and potential for lawsuits. Know what you sell! California is a FULL DISCLOSURE state, sellers are liable to disclose all facts about the property they sell. Many wise sellers have their own mold inspection and mold testing done to avoid surprises and minimize future liability.


Real estate agent
Most professional agents and brokers are keenly aware of the mold issue and how to handle it. However, it is recommended that agents and brokers encourage, as opposed to discourage.  Mold inspection and mold testing should be considered on any occasion where moisture or water problems have occurred.


Property Manager or a Landlord 
Protect your interests and your client's interests by showing due diligence regarding mold in your tenant occupied property. Lawyers are aggressively encouraging tenants to seek legal actions for negligence against landlords regarding mold issues, of which, many times are frivolous. Landlords are mandated by law to provide a healthy indoor environment. Many proactive landlords are now having annual water intrusion inspections, mold inspections and mold testing to ensure against frivolous, as well as legitimate lawsuits. 


Are you a tenant?

Do you have a mold problem that is not your fault? If so, let your landlord or property manager know immediately, preferably in writing. Notify your landlord regardless of whether it is your fault or not, to prevent further damage and contamination. Give them the opportunity to properly investigate and correct the problem before taking matters into your own hands.

What Makes a Good Mold Inspector

As the mold inspection industry evolves, many people have jumped into the mold business to take advantage of the new service as a potential profit center. And, as one might imagine, some are more qualified than others. There are many great mold inspectors who came from other professions, having received superb training and certifications, and who are leading the way by providing top quality mold inspection services to their clients. Many agree the best mold inspectors are those who have an extended background in general building construction and home inspection.

Look for these qualifications before hiring your mold inspector:

  1. IESO (Indoor Environmental Standards Organization) Standards of Practice Certification

  2. BOARD CERTIFIED Certified Residential Mold Inspector (CRMI) by the American Council for Accredited Certification (ACAC), formerly known as American Indoor Air Quality Council (AmIAQC)


Take your time, and ask a lot of questions...get multiple opinions and quotes...and above all, if you are comfortable with a specific mold inspector, don't let the cost be the determining factor regarding who you finally hire!  

Beware of Bad Mold Inspectors

There are a lot of mold inspection companies that play on people's fears to get their money. A true mold problem is handled in three steps.

  1. Initial Inspection: An independent mold inspection and mold testing by a certified and insured mold inspection firm. This step documents the problem and serves as a guide for necessary repairs.

  2. Remove the Mold: Professional mold remediation by an independent certified mold remediation firm (following IICRC 520 standards of practice).

  3. Post-Remediation Inspection: Re-inspection and re-testing by the original inspection company to determine if the repairs were properly and effectively completed.

Never allow the remediation company to perform the post-remediation inspection or testing of their own work. It is a conflict of interest and you can never be certain if the work was done properly.


Your mold inspection firm typically acts as your guide during the process. After the three-step process is complete, you will end up with three separate documents. They represent the acknowledgment of a problem, the repair of the problem and the independent verification that all repairs were successfully completed.


By adhering to the three-step process, not only will you be comfortable that your environment is safe once again, but you will also be protected from real estate devaluation. In today's real estate world, nobody wants to buy a mold problem. Home owners are required by law to disclose home conditions before the home sale.


If you've had water intrusions or leaks which resulted in mold, producing the three documents for the buyer and/or buyers agent will immunize yourself from any attempt at negotiating a lower price due to a mold problem.
