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 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

Black mold on wood is a very serious issue. Besides compromising the structural integrity of the wood, it poses significant health risks. Stachybotrys chartarum, commonly known as toxic black mold, produces mycotoxins that can lead to respiratory issues, allergies, skin irritations, and other health problems. If left untreated, it can spread rapidly and compromise the structural stability of the affected wooden structures. Immediate remediation and preventive measures are essential to mitigate the risks associated with black mold on wood.

You should not run an air conditioner with mold because it could spread the spores throughout your home. Mold exposure can trigger several health problems, including coughing, wheezing, sneezing, itchy eyes, and a sore throat. Living in a moldy house can also increase your risk of other illnesses, including sinus infections, pneumonia, and bronchitis.

The EPA broadly defines hazardous waste as any waste that could pose a danger to humans or the environment. More specifically, it includes any material that could combust or explode under normal temperatures and pressure, as well as materials that are toxic or corrosive. Some common household hazardous waste products include aerosol cans, paint cans, old tires, medical supplies, unused medications, fire extinguishers, cleaning solutions, and lawn care products.

Neglecting mold growth on wood can result in various issues that deteriorate its appearance and jeopardize its structural stability. The mold's ability to multiply and expand can disintegrate the fibers of the wood, weakening it further. In addition, the allergenic spores and mycotoxins released by mold can pose health hazards through inhalation or contact. Ignoring the mold's presence allows it to thrive, increasing the likelihood of spreading to other surfaces and requiring extensive and expensive measures to control in the future. Addressing mold on wood promptly is crucial to preserving its condition and safeguarding the health of those around it.

Before you start removing mold, turn off the furnace. Clean away any visible mold from accessible areas using a mixture of water and mild detergent. Change air filters and check for moisture sources like leaks. If the problem persists or it's widespread, hire a local HVAC company for professional cleaning.
