Our comprehensive process combines certified inspectors, accredited lab analysis, and expert review for fast and accurate mold inspection and indoor air quality results.

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.

We perform a comprehensive inspection which includes visual & infrared screening and moisture detection to detect hidden moisture, and we collect air and surface samples from suspected mold-affected areas.

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.

Samples are analyzed at an AIHA-accredited lab — species identified, spore counts measured — and every result is reviewed by our on-staff microbiologist.

We send you a comprehensive interactive web report containing plain-English findings, microbiologist-verified testing results, recommendations for mold remediation and improved air quality, along with preventive tips to avoid future issues.

Common questions about mold, testing, and our process.
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.
Our lab partners typically return mold test results within 1–2 business days. Your inspector will discuss the findings with you once they're available.
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.
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.
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.
Yes. In Houston, there is often flooding. This can leave water hidden inside walls and floors. For water trapped in a wall after a flood, see how testing for mold in walls works. 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.
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.
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.
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.
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.
