"Brian with Southside mold and testing is one of the best companies I have ever experienced. Discovering mold in your home for us was very unsettling and scary. From the first phone call with Brian to the mold remedy completion, we received service excellence and piece of mind. Brian is very talented, knowledgeable and professional. He explained in detail the what, how and why about the project in its entirety. Even with the price being great, I am still not one to hire service without having at least two or three professional quotes and opinions but this Company and Brian made it apparent to look no further. Thank you Southside Mold and testing and THANK YOU BRIAN!!"

"We have a cold room for adhesive storage and had a horrible case of mold due to an incorrect build out. I called these guys and they came out very quickly. They removed all of the mold along with infested ceiling tiles and paint the fell off of the wall during the process. They left the walls looking new again and cleaned their mess. We have not had a mold issue since. I highly recommend these professionals!"

"Overall was good for what the service is. The technician was a postal worker and home inspector. So mold test company appears to be brokers. Their pricing was competitive from other quotes I received but I honestly think it was pricey for time spent and what they do. But like I said the price was pretty standard from the companies I called, in my opinion. But the technician was attentive and knowledgeable, and friendly."

"When I went looking for flooring at a local store, the man said there was a good chance the tiles and glue were asbestos. My research indicated I could just cover the floor (encapsulate it) or remediate it. Even though it was expensive, I thought it best to remediate it. I used Angi's which is what I ALWAYS do and looked up service providers. I called a couple of them and got prices. Environmental was not the cheapest, but Maximus made me feel comfortable. He not only reviewed what needed to be done in the basement, he advised me about other things, as well. I felt like he really knew what he was doing, and he spent time with me. He gave me options, and I think he went above and beyond."

"On 3/10/26 our community was struck by a tornado. We called Flawless restoration that night and by 9:00am the next morning (3/11/26) they had a crew at our home. They were professional and did a GREAT job. At a time when they could have price gouged us, they did not. Their price was very reasonable. we highly recommend them."

Mold Testing and Remediation FAQs, answered by experts

Mildew and mold are not different—mildew is a specific type of mold and yes, it can become dangerous if left untreated. It would be amazing if we were all biochemists but because we most likely aren’t, it isn’t wise to assume any mold is mildew on sight alone. Harmless mold and toxigenic mold (which can be deadly) look very similar, so if you see any new mold that looks even a little suspect, call a mold professional immediately.

Yes, mold behind drywall can affect your health, even if it is not visible. Mold releases spores and mycotoxins into the air that can be inhaled, leading to various health issues including respiratory problems, allergies, asthma symptoms, coughs, and other infections. While individuals with pre-existing conditions like allergies, asthma, or weakened immune systems are particularly vulnerable, anyone can be affected by prolonged exposure. Additionally, if left untreated, mold can spread throughout your home and compromise its structural integrity, resulting in costly repairs.

If you see black stuff under your vinyl flooring, it’s probably mold. There is a chance it could just be dirt, dried-out adhesive, or slight water damage, but some of those are causes for mold growth, so you should remove it immediately anyway. In some older homes, it could be black mastic asbestos. If you think it could be this–you guessed it–call a pro.

A stain from a water leak will usually be brown and concentrated in a single area where the water is originating from. You may find it under a damaged section of roof, under an upstairs bathroom, or beneath your HVAC system. Stains from condensation are more likely to be widespread since they don’t come from a single point of water intrusion. Condensation stains also look blotchy and may smell musty, and they won’t be concentrated in a single area on your ceiling.

Seeing black dots around the air vents is alarming, but don’t worry. It’s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months.
