"Dave was extremely helpful in giving grounded, low cost solutions for my ongoing mold issue. Proving sound and reliable advice in a sea of so much overwhelming information was invaluable. He took the time to look over a previous report that provided misguided information and recommendations and took the time to walk me through the correct steps saving me so much time and headache. Thank you so so much. I highly recommend this company for their mold services and consult."

"This was not the first time using an Air Quality inspection company. They were help full, accessible, timely, accurate, and provided an analysis report that included a representative to review and answer questions. They also provided a referral to a remediation company that approached the issue in an efficient and cost effective manner."

"Many people advised me not to contact a Mold Inspector, because â They always find moldâ . These are people who donâ t go to dentists because they might find cavities. The first time I hired Steve Ramos, he found â No Moldâ on the property I asked him to inspect so I knew I could trust him. This year I suspected I had mold in my rental property and wanted to be sure my pregnant tenant was safe. Steve not only found the source of mold, he told me exactly what type of mold I was dealing with, what the risks were to my tenant and unborn child, and what steps I needed to take to eliminate it. He was always available, and still is, to answer my questions and work with my contractor to insure a safe environment for my tenants and their baby. Nobody wants to have to call a mold inspector, but if you do, I urge you to call Steve Ramos. He is not only excellent on a professional level, he is also honest and caring on a personal, human level and goes way beyond his job description to help his clients."

"The introductory meeting went very well. The representative, Stephan, was very professional, arrived on time and had a professional appearance. He asked good questions , so to understand the extent of our rodent house mates and wanted to see all areas of the house inside and out. He completed a thorough inspection and educated me with his findings and clearly proposed what his company could do to remove the mice. We signed up and are looking forward to being mouse free!"

Mold Testing and Remediation questions, answered by experts

Several factors affect the color of mold, including humidity levels, age of the mold, and amount of light it receives. A patch of mold that starts out green may darken and turn black as it ages. A species of mold may be green if growing in one environment, but be black in another environment. Color usually isn't a reliable way to determine mold species or risk.

In some cases, black stains on brick are caused by organic substances like algae and mold. However, it's more likely that the black spots you're noticing on your bricks come from carbon from vehicle exhaust or soot. Black stains can usually be removed by scrubbing the brick with a brush and masonry cleaner or power washing.

Costs depend on property size, test types, and additional services like mold sampling.

In mild cases of mold growth, you can DIY mold remediation with a simple cleaning using safe and natural cleaning solutions like baking soda, hydrogen peroxide, vinegar, or lemon juice. However, if the mold is larger than 10 square feet or you suspect toxic black mold, you should not do mold remediation on your own. Instead, you should hire a professional mold removal company to handle the job.

The primary difference is that black mold (Stachybotrys chartarum) is considered toxic and more dangerous than regular mold. It can produce harmful chemicals called mycotoxins, which may lead to severe health issues like respiratory problems, skin irritation, headaches, and other long-term complications. While regular mold is rarely toxic, it can still cause allergic reactions and respiratory irritation. Visually, black mold often appears dark—green, gray, brown, or black—with a fuzzy texture, whereas regular mold can be almost any color. Black mold is less common and typically grows in areas with severe water damage. Regardless of the type, you should not ignore any mold infestation in your home.
