"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."

"Had an emergency - time sensitive need to conduct a mold test and they worked with me and made it possible the very next morning. Can't tell you how important this was since my landlord's insurance hired mold "specialist" showed up a week later, with much different results. Great follow-up experience with Austin R."

"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

Professional carpet cleaning can cause mold if the job is not done properly. There are two ways this can happen—if your carpet cleaner fails to dry the carpet properly, or if your carpet cleaner uses an excessive amount of water during the cleaning process. Mold can grow wherever moisture is present, so make sure you hire a pro who knows the process inside and out.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Frequently, fungi have a gray color with a powdery or fuzzy texture on a wall. In showers, fungi and mildew may resemble a pink slime. Meanwhile, toxic mold may resemble a fuzzy growth on walls that’s often black or green in color. Some toxic black mold will have specks of orange or white on it. However, not all dark-colored mold you find on a wall is toxic. An infestation of toxic mold often will spread faster than fungi on walls. If you are unsure whether you have toxic mold, reach out to a professional for help.

Most grass mold isn’t harmful to humans. Slime molds in particular aren’t toxic and may even possess some benefits. Other molds, like powdery mildew and snow mold, generally aren’t a concern, but can still cause allergic reactions and respiratory distress in those with high allergy risk and compromised immune systems.  

Since most mushrooms are beneficial for your grass, and otherwise harmless, it’s not a good idea to kill them with fungicide. If you suspect you have a poisonous type of mushroom in your grass, you should consult a professional concerning mitigation. There are lots of types of mushrooms and most are perfectly safe.
