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.

"The mold testing is fine. The mold remediation company is very sketchy. Just buy some air purifiers."

ATLAS Environmental Inspections is a fully licensed and fully insured environmental inspection firm offering experienced and professional mold and asbestos testing services to residential, commercial, and industrial clients in the greater Philadelphia, Chester, Montgomery, Bucks, and Delaware counties. ATLAS Environmental Inspections continually strives to provide professional, courteous, and accurate environmental inspection services with an emphasis on total customer satisfaction. Atlas Environmental Inspections believes in partnering with its clients and attempts to simplify highly technical industrial or chemical jargon into a more understandable context. Most of our clients have never been exposed to an environmental hazard and consequently do not know where to turn for testing or what steps to take in addressing these concerns.

"I had a bad experience with a different company, and so, I was a little skeptical and wary when I started working with Jason. He was very patient with me, showed me all his credentials, took the time to explain what he would be doing and why, and otherwise showed me that he runs a competent and professional outfit. The type of test they took satisfied my insurance company and they even offered to let me pay after the test was done. In short, I am 100% satisfied with Jason and Atlas Environmental Inspections. It was great being able to work with such a great company after having had that previous bad experience."

Mold Testing and Remediation questions, answered by experts

Identifying harmful strains of mold helps prevent respiratory and allergic reactions.

Nearly all homes have at least some airborne mold spores. If you want to determine the concentration of spores in the air, you have a few options. The most effective option is to hire a professional tester who can take air samples of the home. The tester would send the samples to a laboratory to determine the concentration of mold spores. 

Signs you may need mold remediation include visible mold growth on walls or ceilings, a persistent musty odor, or health symptoms like allergies and respiratory issues. Areas affected by water damage or excessive humidity are prone to hidden mold. A professional inspection can confirm whether mold remediation is required, especially for large or concealed infestations.

Mold inspections are worth it because they can catch troublesome mold problems early before they get out of hand. It's worth it to address mold problems as soon as possible because mold can be hazardous to your health and cause damage to your home and its belongings. Mold testing and inspections are the best way to know if you have a mold issue in your house.

Musty smells often indicate the presence of mold, which can lead to various health risks. Inhalation of mold spores may trigger allergic reactions, causing sneezing, a runny or stuffy nose, and itchy or watery eyes. People who suffer from mold allergies or asthma may experience more severe respiratory problems. Certain types of mold, like black mold, can lead to mycotoxicosis, a condition associated with serious health effects like respiratory problems, fatigue, headaches, and skin irritation if exposure continues for an extended period. Those with weakened immune systems, respiratory problems, or allergies may be more vulnerable to the health risks that come with musty smells. Therefore, it is crucial to address and eliminate the source of the odor promptly.
