"WOW!! Joel was an absolute pleasure to work with. He’s a great communicator and took lots of time to explain the work to us. I’ve done a lot of research about mold remediation, and everything I read was in line with what Joel told me. Our aging relative was worried and stressed about the upheaval of a large remediation project, and Joel and his team were SO kind and understanding of him. I feel that we got a great value for our money, and the project was finished on time. I highly recommend this company."

"Ted from Biotek noted that since I had already done some home project work, the fix needed was actually something I could do myself. He gave great feedback on the root problem for moisture continuing to build up was the lack of a hose feeding to a vent from the bathroom fan, and that a simple dryer hose running to an existing vent exit in the attic would help on that front. He then gave steps on using a vinegar solution, elbow grease, and letting the area dry for several days (avoid that shower) after killing the existing mold, before applying a layer of mold sealing primer (like Killz). He saved me at least $2500 compared to some quotes I'd received to take care of the problem."

"I am not lying when I saw that EnviroFry is the best business/company I have ever worked with or hired in my entire life. My son was severely ill with mold illness and PANS and it took FOUR mold companies to find all of the hidden mold in our home… EnviroFry was the company that finally found all of the mold. They are like mold finding ninjas. Not only are they the most skilled at what they do (I would literally fly them across the globe if I had to because they are the only ones I trust) but they are the most amazing, kind, compassionate, and loving people… just the type of people you need with you and advising you when you are scared and overwhelmed. We have now been back in our home for 3 years and everyone is healthy and doing great. We had a successful remediation. I recommend them to everyone I know and they have helped so many friends and family members of mine and all of them feel the same as I do about their excellence."

"I would recommend this company for asbestos abatement. I was very grateful that they were able to help me in such short notice to remove the asbestos when another company did not show. I thought their price was pretty fair and was told by the mold testing company that they do good work. I would not hire this company to do anything else. I was in a bind and got a quote on what it would be to mud and paint the ceiling and paint the house. I was very very unhappy with the quality of the work of the painters he hired. I feel I should have been deeply reimbursed or discounted because the paint job was so bad. They got plaster everywhere on my kitchen cabinets and are unable to remove it so I must just look at it. They did not replace some of my lights and there are cracks in the seems and every worker I have comments on how bad the paint job is. Very dissapointed that I spent so much money for that. They came out to try and fix it and it was not even fixed. Maybe a little better on the ceilings. It was extremely hard to get the electrician that I hired through them to come up and finish the job here in Charleston. I believe he lived a few hours away and everything was just a headache. He was unable to find a certain part and I ended up having to research and find it online. We lost at least a week while he was looking for that."

"I purchased a 1920's Bungalow and discovered after a very heavy rainfall the crawl space flooded, which led to a very musty smell in my house. I hired a different company who tested and said there was various mold including black mold, but could not find it. I then contacted EnviroFry. Deven and William tested and found it in my attic and crawl space. They removed the mold in the attic and in the crawl space, installed a French drainage system inside the crawl space and encapsulated it with vapor barrier. They cleaned my ducts and fogged my HVAC and house. They were very professional and are wonderful people! I have already recommended them to people I know. I highly recommend them!"

Mold Testing and Remediation FAQs, answered by experts

Homes should be checked for mold annually, especially if you live in an area with high humidity or frequent rainfall. Inspections are crucial following flooding, roof leaks, or plumbing issues. More frequent checks are necessary if your home has a history of mold problems or water damage. Regular inspections help detect mold early, preventing costly remediation and minimizing health risks, especially in moisture-prone areas such as basements and bathrooms.

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.

The most common sign of a carbon monoxide leak is the visible black soot marks on the walls near your wood stove. An excess accumulation of smoke in other rooms of your home could also indicate that your wood burning stove is leaking carbon monoxide. If you notice either of these signs or are still unsure, it’s best to leave the premises and contact your fire department to check your home’s levels. 

Some mold can look like dust, but most doesn’t. Powdery mildew is often confused with dust as it’s a similar color and grows in a similar way. Some gray molds can look like dust as well, but usually, it’s pretty easy to spot the difference. It’s better to be safe, so if you aren’t completely sure what you’re seeing is dust, call a mold professional to check it out.

White mold is generally considered less harmful than black mold, which can be more toxic due to the mycotoxins it produces. However, white mold can still be harmful, particularly for individuals with mold allergies, asthma, or other respiratory conditions. Exposure can cause symptoms like nasal stuffiness, throat irritation, coughing, or skin irritation, and it can exacerbate existing health issues. Because any type of mold can pose health risks, all mold infestations should be treated seriously. Prompt remediation is necessary, and you should take proper precautions, such as wearing protective gear and using appropriate cleaning agents, when dealing with it.
