"When I called the mold company for my lab results. They gave me a person named Ricardo Echeverria, Senior Mold Analyst to call for the results. He verbally told me that the cause was something like a remodel, construction going on. There was a red flag for a VOC called Methylene Chloride--Banned outdated paint. I sent Ricardo and email asking if I can have a report of what he said in writing. I only received a contaminants list. I said, I am not a scientist and do not understand the lab results.I never received a response back from him. I called Jeremiah Bancroft a few times and asked for a written explanation of the causes. He could not supply me with a written explanation because it was a legal issue. I asked for his help. I need your help. Jeremiah said, go to your primary care for a doctors note. That was the last time I spoke to him on September 19, 2024"

"FANTASTIC ! Ryan showed up and looked the job over. He identified areas that needed to be sampled / tested. Very professional, safe and hard working team. My wife has asthma so Ryan told me they would be extra careful about dust, etc. They were GREAT throughout the entire remidiation process. They cleaned up the site at the close of each work day. Communication was clear and professional throughout the entire project from Ryan and his team. Would definitely hire him again should the need arise."

Mold Testing and Remediation questions, answered by experts

Mold remediation costs $1,125 to $3,345 to remove mold with a national average cost of $2,225. The reason the cost is high is because there are various health risks associated with toxic mold, such as respiratory distress and carcinogens, with some molds even causing damage to your nervous system. Remediation is not only about removing the mold, but fixing issues that could contribute to future growth. The last thing anyone wants is a toxic mold returning.

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.

Mold can begin to grow in as little as 12 to 24 hours, especially if the room is warm, so drying the area is the first thing you should do after water damage. Because mold and mildew can cause a range of health issues, make sure you clean up any water damage as soon as possible and run blower fans and dehumidifiers for 24 to 72 hours to dry out the room and reduce the risk of mold growth.

Yes, limewash is free of volatile organic compounds (VOCs). Made of lime and water, it is eco-friendly, breathable, and toxin-free. Most synthetic paints have low to high levels of VOCs, which causes their irritating odor, which can have adverse and long-term effects on your health. Conversely, limewash consists of crushed limestone, which undergoes burning, mixing, and aging before being diluted with water—natural pigments add coloration.
