Inspections Only – Not Remediation
Unlike cheaper companies with a conflict of interest, our partners provide unbiased assessments because they don't profit from finding problems. Our only job is to make sure you get the truth, not buy services you don't need.
Texas Occupations Code 1958.155(a) prohibits licensed mold inspectors from both inspecting and cleaning/remediating. We follow this ethical standard nationwide, even where not legally required.
Advanced Inspection Protocol
Our comprehensive process combines cutting-edge AI technology with expert analysis for fast and accurate mold inspection and indoor air quality results.

Pre-inspection Survey
Initial consultation discussing property history, past water damage, and moisture problems. This survey takes 10 minutes and can be done over the phone or in-person.

Property Inspection
Using our own industry leading AI software we perform a comprehensive inspection which includes visual & infrared screening, moisture detection to detect hidden moisture, and collect air and surface samples from suspected mold-affected areas.

Indoor Air Quality Assessment
We use advanced chemical and particulate sensors to detect formaldehydes, volatile organic compounds, fine particulates (PM2.5), carbon dioxide, and other contaminants that may cause similar symptoms to toxic mold exposure.

AI Sample Analysis
Using our proprietary Marvin Lens AI technology, we analyze air and surface samples, identifying and counting mold spores within hours of collection. Results are reviewed by our on-staff microbiologist for accuracy.

Reporting & Advice
We send you a comprehensive interactive report with our AI helper containing findings, testing results, recommendations for mold remediation and improved air quality, along with preventive tips to avoid future issues.

Frequently Asked Questions
Common questions about mold, testing, and our process.
How do I know if I need a mold inspection?
You may need a mold inspection if you notice musty odors, have experienced recent water damage, or are facing unexplained health issues like headaches or respiratory symptoms. Mold often grows in hidden areas, so a professional evaluation can help identify any problems.
How long does it take to get mold test results?
Our lab partners typically return mold test results within 1 to 3 business days. In urgent cases, same-day results may be available. Your inspector will discuss the findings with you once they're available.
Is mold dangerous to health?
Yes, certain molds release allergens or mycotoxins that can cause health issues, especially in children, the elderly, or individuals with preexisting respiratory conditions. Common symptoms include coughing, sneezing, and eye irritation.
Can mold testing confirm if my AC system is spreading mold through the house?
Yes. Houston is known for its high humidity. This can make HVAC systems a big source of mold. Moisture builds up inside the coils and parts where the air moves. This helps mold grow and its tiny parts get into the air. Air sampling can help find out if there is mold moving around your system. This is helpful even if you do not see any mold.
Will mold testing help determine if the damage is from a recent event or an ongoing issue?
Yes. When you look at what you find during an inspection and what comes from lab tests, you can see if mold is growing now and if it started after something like a storm or leak. You can also learn if there has been a problem with water for a long time. This helps know how fast you need to act and what you should do next.
Can mold testing help me prove the extent of damage after flooding?
Yes. In Houston, there is often flooding. This can leave water hidden inside walls and floors. Mold testing helps to find out if there is any contamination. It also helps to see how much it has spread. This is important to show any damage and to know how to fix it.
Is mold testing important if my home smells musty but I don’t see anything?
Yes. A musty smell often comes from hidden mold or too much moisture in your place. A professional test can find mold in the air even if you can’t see any mold. This helps to find out where the problem is coming from.
Can mold testing show whether the issue is affecting just one area or the entire home?
Yes. Mold testing looks at several samples from inside and outside the building. It helps find out if the mold is only in one area or if it has spread everywhere. This step is needed before you choose the best way to fix the problem.
Will mold testing help me avoid unnecessary full-home remediation?
Yes. If you don't test, you might think things are worse than they are and pay too much for big cleanup jobs. Lab results show you where the mold is and how bad it is. This helps you fix the problem in the right spot so you do not spend more money than you need to.
Can mold testing help if there are no clear regulations or enforcement in Houston?
Yes. Houston does not have strict rules for taking care of mold, mainly in the places that people rent out. That is why it is very important for you to have your own records. Testing gives you clear, test-based proof. This helps you in case there is a problem or when you need to make a choice.
