When you have mold, making the correct decisions right away is critical. Whether it is mold in your home, school, place of work, or apartment there are many factors to consider. Are you going to be involved in a mold lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need post mold remediation testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It is important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages and property damages require different environmental tests to prove your case in court. Tests that a common, or inexperienced, mold inspector would not typically use or know to use.

"They did a prompt professional job. I received the report in about 7 days. Mold was found in the air due to high humidity in the air. All of this seemed OK but then I was forwarded to the Biocide company that tried to get me to buy a DIY mold remediation kit. There a time pressure to buy the kit for the best price at $2400. They said the nature of the mold would require a hazardous work fee from any remediation company that would cost from $12,000 - 18,000. This is when I started questioning the service I received. My pulmonologist also looked at the test results & said the mold levels did not seem too bad. Also, the humidity readings on my house thermostat did not read the high level that the report stated. So, I do not know if there was any value with the service & I am not sure if I would recommend them. The only way to really find out would be to call in another testing company but I did not want to spend another $660. So, I had the remediation work done for $1900 & was satisfied."

Certified Mold Removal has been providing expert licensed and certified mold inspection, testing, removal and remediation services Since 1995! Not All Mold is Dangerous! Don't Let Other Companies Scare You! Call now and we can have a licensed and certified mold inspector at your home today!

"Alaert! I hired this company to test the air in my detached garage and paid $600 for the mold test. The results showed Cladosporium, which is one of the most common molds found both indoors and outdoors. What I didn?t expect was the remediation proposal that followed: over $45,000 in recommended work for a detached garage. In my personal opinion, the scope and price were extremely excessive for the type of mold identified. The quote included multiple rounds of fogging, containment, demolition, and even pages of alarming health claims ? including everything from depression to cancer ? that felt more like fear tactics than practical guidance. I?m not a mold expert, but after getting additional opinions, it was clear to me that the recommended work and the severity of the warnings did not match the situation. I chose not to move forward. If you?re considering this company, I highly recommend getting multiple quotes and doing your own research. My experience left me very uncomfortable"

Our services include Mold Testing, Remediation and Water Extraction as well as Air Duct Cleaning and Sanitizing. We have more than thirty years experience in the building industry. We are capable of repairing any damage caused by mold, water, fire or the remediation itself. We have full compliment of licensed sub- contractors, Electric, Plumbing, Masons etc. Servicing all of New Jersey.

"AMS is our HERO. The city sewer backed up and filled one third of our basement just before kickoff on Super Bowl Sunday. By halftime George had arrived. He calmly assessed the situation, and set up a time to return the following morning. His workers were polite, professional, and meticulous, and did an unbelievable job of cleaning up a horrible mess. By the end of the day the damaged items, sewage , and much of the smell was gone. Huge fans and a germ-killing ionizer ran for three days. When they were finished the floor was bone dry and absolutely clean. It occurred to us that the floor could not have been better cleaned if it were being prepped for painting. So we will be doing so. AMS has innate integrity and a wealth of knowledge across a wide spectrum. Any project can be entrusted to their competent hands. Chester and Jean Lehmann"

Mold Testing and Remediation questions, answered by experts

Early signs of asbestos exposure might not immediately manifest. Over time, symptoms may include persistent coughing, chest pain, shortness of breath, and fatigue. However, these symptoms can mirror other respiratory conditions, making diagnosis challenging. Seeking medical evaluation is crucial for early detection and intervention.

Determining if vermiculite contains asbestos requires professional testing. Visual inspection alone cannot confirm the presence of asbestos fibers, as these fibers are so small that they are not visible to the naked eye. A certified asbestos inspector will collect samples of the vermiculite insulation and send them to a laboratory for analysis. Microscopic examination using polarized light microscopy (PLM) or transmission electron microscopy (TEM) is necessary to accurately identify asbestos fibers. DIY sampling is strongly discouraged due to the potential health risks associated with asbestos exposure.

There are two types of mold symptoms in the home: visible mold and unexplained health issues. If you have allergies out-of-season, brain fog with no other obvious cause, constant congestion, and other such symptoms, you may have a mold problem. Oftentimes you can smell mold in your home, even if you can’t see it. 

Mold can damage the surface it’s growing on, cause mold-related sickness, and even affect your upper respiratory system.

According to the EPA, mold allergies are common and can cause skin irritation, respiratory problems, headaches, and other allergic reactions. Mold allergies can also trigger asthma attacks in people with asthma. Additionally, some molds produce mycotoxins, which can lead to very serious conditions, like lung cancer.
