Customers say: True professional

"No one wants to find mold in their home (or in our case, the home we were buying), but everyone wants to find good, reliable, knowledgeable people to help them, and Johnnie definitely fits the bill. We were referred to Johnnie and got him on-site the very next day he was very accommodating. He spent a ton of time not only carefully working in the house, but gave generously of his time to explain things to us thoroughly. He was very honest, gave us his unfiltered assessment based on his expertise (which we appreciated), and we can not recommend him enough. If you are looking for someone who is personable, reliable, reasonably priced, and really good at their job, hire him, you will not be disappointed."

"Thomas Candella did a great job identifying the source of the mold issue, managing and remediating the mold - this was my first experience with mold and Tom was very patient with all my questions. He was professional at all times - from the first call to Robert Kye, the owner to the last visit, putting up the drywall, painting and providing pictures for submission to the insurance - I highly recommend Certified Mold Removal, Inc for all your mold issues. Mold in the home is not healthy."

"Project: Remove damaged kitchen cabinets and sheet rock caused by water damage. They came in with a crew of workers and removed the cabinets and drywall and insulation. Performed Mold Remediation where needed. Set up blowers to dry everything out. Very professional and reliable. They cleaned every thing up and left the area spotless. Would highly recommend."

"When I initially discovered I might have had asbestos in my cracked flooring, I was very anxious and scared. I got connected with Christian the same night the discovery happened. He answered a lot of my panicked questions with calm and patience. As frantic as I was he was very understanding and helpful. My experience with Christian was great and I definitely would recommend him. I contacted another asbestos tester before reaching Christian, and they treated me with disrespect and could not care less. If you want someone who is understanding and attentive to your situation, dont look anywhere else! Thanks again Christian!"

"Extremely professional operation. These are the best people to use to diagnose any indoor air quality or mold, radon, etc. To me, it’s important to separate the person evaluating the condition from a company that also happens to offer remediation services. That’s my personal opinion and not any type of blanket statement. They were readily available, the Lead Contact was a. man named Mark Stern, who is a total Environmental professional. Fortunately, we had no issues, but wanted peace of mind, which we got in a very detailed Inspection and Report within a day or so. Happy to recommend them to Inspect, Test and Report on possible Indoor air safety issues."

Mold Testing and Remediation FAQs, answered by experts

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

If you’re worried mold might still be lingering after you’ve cleaned your items, here are signs to watch for:

  • Musty smell

  • Visible spots or stains

  • Allergy symptoms when you’re around the item

  • Damp or sticky feel.

If you notice these signs, it might be time to let go of the item or get professional treatment.

Yes, a refrigerant leak is extremely toxic and dangerous to breathe. Refrigerants can displace oxygen in a room, which can lead to suffocation, loss of consciousness, serious health issues, and even death. You may also suffer from refrigerant poisoning, which can cause symptoms like headaches, nausea, dizziness, swelling of the throat or sinuses, vision loss, and a burning sensation in your eyes, ears, nose, lips, and tongue. If you experience any of these symptoms, you should seek medical attention immediately. In addition, refrigerant leaks are toxic to the environment and can cause permanent damage to the ozone layer.

Black discoloration on your attic insulation may be caused by buildup from soot, dust, or dirt, which does not come with dampness or a musty odor. However, another cause of black discoloration on attic insulation is black mold, which has a musty smell and other signs of damage. If you’re unsure what black stuff you’re looking at, consult a pro to be safe.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.
