"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."

Customers say: True professional

"I am so grateful to Johnnie and Chris from Mid Hudson Home Restoration! My husband and I hired them on two separate occasions. First hire - there was water damage in the basement and possible mold. I consulted with Johnnie over the phone and he quickly arranged for a visit. He quoted us that the work will be done in 3-5 days. Johnnie and Chris carefully took apart the dry wall, remediated the mold, and sealed everything up again in the timeframe they promised. They also repainted our entire basement and did a great phenomenal job. Second hire - we had a ceiling leak from an unknown source. Johnnie cleared his schedule for us and came immediately once he saw the video we sent. He found the source of the leak within minutes and over the next couple days, replacing the ceiling and sealed everything up. Johnnie and Chris are detail oriented and thorough with their work. Above all, they are warm, honest people who truly care and take pride in what they do."

"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."

"Montclair township has a requirement for landlords to perform a visual lead paint inspection on a regular basis. Christian did this work for me, walking through my apartments and letting me know what spots needed to be touched up with paint. Then he provides a certificate to send to the town. Christian is communicative, reliable, prompt, and professional. He turned the certificate around really fast, too. I can’t recommend him more highly to anyone who needs environmental inspections in their home."

"I just got done speaking to Spencer on the phone who was very generous with his time running through all the potential contaminant issues, breakdown of Oasis services, and was very candid on whether i should even proceed with any testing. If i do proceed I will certainly pick this company."

"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

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.

Thorough inspection, air quality tests, and surface sampling to detect mold presence and levels.

Some causes of brown well water—like excess tannins or dissolved iron—don’t pose a health risk. In other cases, harmful bacteria might be the culprit. If your well water has suddenly turned brown, it’s a good idea to use a home water test kit to get a better sense of what’s going on with your water. Consider calling a professional for an expert opinion before drinking the water and hoping for the best.

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

Humidity, moisture, and a lack of ventilation can all cause mold to grow on surfaces in and around your home.
