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"

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

Certainly, DIY mold tests are not perfect when trying to determine whether you have a mold problem. They could give you a false positive reading, or they may fail to detect mold that’s behind a wall, especially if the infestation is still small. Ultimately, you should seek a mold inspection if the DIY test gives you a positive result, just to be certain. And if the test is inconclusive, it’s probably worth seeking an inspection from a pro.

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.

Slime mold isn’t toxic to your dog, even if they eat it. Toxicity and comfort are two different things, and if you notice your dog eating slime mold, you should stop them, but not worry too much. Expect a period of gastrointestinal distress, and possibly some other complications, but your dog should be ok within a few days.

It is not advisable to stay in a house with black mold. Exposure to black mold, or any mold, can lead to health problems, especially for vulnerable individuals such as children, the elderly, or those with weakened immune systems. Black mold produces mycotoxins, which can cause respiratory issues, skin irritation, fatigue, and headaches. If black mold is detected, it is crucial to evacuate the premises, seek professional help for remediation, and only return once the area is thoroughly cleaned and confirmed mold-free by experts.

A mold inspection costs $660 for the average homeowner. This cost can range anywhere from $150 to $2.800, depending on the size of your home, the number and type of samples, and the number of hard-to-reach areas of your home that need testing. 

Places like air ducts, crawl spaces, and wall cavities are particularly inviting for mold spores but require more time from your mold inspection pro. Additionally, swab testing, where a surface sample from an area of your home is collected, generally costs $200 to $300 per area. Air testing, however, is more costly, ranging from $250 to $350, but can cost as much as $700.
