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

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

PVC is not considered a hazardous waste in most areas, but regulations vary by location. If in doubt, you should contact your local sanitation department to confirm. The Center for Biological Diversity (CBD) has been working to get PVC classified as hazardous waste, so it’s possible that it will be considered as such in the near future. If it is, disposing of PVC will require the use of a hazardous waste disposal facility or transporter in your area.

The high humidity of steam showers creates the ideal environment for mold growth, so it’s important to stay proactive against it. Along with regular cleaning, run your bathroom fan during and after your steam shower. Keep your shower door open and any doors and windows in the bathroom to allow the space to air out properly. If you come across ugly mold spores, spray them with undiluted vinegar, let it sit for at least an hour, and then scrub away the mold.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

If you notice water accumulating in your vent due to a roof or plumbing leak above your ductwork, it's essential to promptly identify the source of the leak and undertake any required repairs without delay. Such leaks have the potential to swiftly result in water damage within your home, ultimately leading to mold and mildew concerns.
