"I received my call earlier today, and discussed my concerns. I wanted to start the process toward remediation asap! Mr. Griffin was at my house 4 hrs later. He was professional, compassionate, and answered all my questions, since this was a new experience for me and of concern. By 3pm, my home was totally inspected and my airborne samples were collected and headed to the GA lab for testing and results. Within minutes, a email to track my lab results status was sent to my phone! I can't do anything until the results are determined,and Mr. Turner, Senior Mold Analyst gets the report! The ball is rolling! MsV"

"Very well. Will serviced the house. He suspected there could be mold in the ducts, because there wasn't any in the furnace itself. I had burning sensations in my eyes and throat and that usually is generated by mold. The burning continues, so I'm not sure there was a mold issue, but I'm glad I had the service done just in case there was. Will is very professional. Explained everything that he was going to do. He left the house in the same condition as when he arrived. Also, he was quick to say that if I had any problems in the future, he would be glad to come back."

"Eric and his crew, Christopher and Joe, did a great job. Eric informed us of his three day plan to complete the job and it went exactly as he stated. They showed up on time and kept us informed throughout the process. The price was fair and exactly as quoted. In addition, they were courteous and professional. I highly recommend Fox Environmental Services."

"We had a good experience with this company performing mold removal and installation of a water proofing system in our basement. They took the extra time to really evaluate the mold and water issues we had in our basement and explained in detail all of our options and the process involved in the resolution. The crew was knowledgeable, and professional. They reviewed the scope of work with us to make sure we were pleased with the process and results. They showed us pictures of the progress, tested the system sump pump in front of us, and went over how everything was put together and how the system will function. They also provide a good comprehensive warranty on the system. We'd recommend this company to anyone out there with similar issues in their basement."

Mold Testing and Remediation FAQs, answered by experts

Yes, it is common for mold to grow on the underside of the siding due to the moist atmosphere. When there is an abundance of moisture, mold has the ideal environment to spread and thrive. This fungus can be found on virtually any surface, both indoors and outdoors. Generally, it is most active when the environment is warm, damp, and humid.

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

A mold inspection costs an average of $660, with a typical range between $300 and $1,025. However, costs can be as low as $150 or as high as $2,800 depending on several factors. These include the size of your home, the type of mold, the extent and accessibility of the affected area, your location, and the number and type of samples required. Hard-to-reach areas like air ducts, crawl spaces, and wall cavities can increase the cost. Specific tests have different prices; for example, swab testing typically costs $200 to $300 per area, while more extensive air testing can range from $250 to $700. A thorough inspection is crucial for determining the scope of the problem and identifying the best remediation method.

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

Black mold and wood rot are both types of fungi that thrive in damp areas, but they are distinct issues with different consequences. Wood rot specifically refers to the decay of wood caused by fungi, which compromises the wood's structural integrity. Black mold, on the other hand, is a fungus that grows on the surface of materials, including both rotting and non-rotting wood. The primary difference is their impact: wood rot affects the wood's structure, while toxic black mold is a health hazard. Inhaling black mold spores can cause severe respiratory issues, whereas wood rot spores are generally not harmful to people. Because mold can grow on rotting wood, the two issues can be interconnected, but they are not the same.
