"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 There was a red flag for a VOC called Methylene Chloride--Banned outdated paint.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"

We offer residential mold inspections, air quality testing for molds and allergens, and radon measurements. We're BBB Accredited and for the past three years have been awarded the BBB Certificate of Customer Satisfaction and Excellence! Our mold inspections evaluate both external and internal conditions of your property and identify when there is mold. We utilize air quality sampling and surface sampling to identify the types and concentrations of mold spores using accredited 3rd party laboratories. Our inspections also identify conditions that could cause mold in the future and can save thousands on expensive remediations. In the event of a small mold contamination, we can remediate to return the area to a pre-mold healthy condition. For larger remediations, we can refer you to a number of excellent remediation companies that we work with. Our radon measurements use state of the art CRM's (Continuous Radon Monitor) that provide important data on radon levels within the environment. We also offer Electret ion Radon measurements for longer term measurements, or for those looking for a slightly less expensive solution. We're fully insured, certified and licensed and we educate our clients while we go about our business! This has been very well received as we believe our clients want to understand just what they're paying for and it helps prevent future issues. Check out our services offered and call or click to schedule an inspection or measurement today!

Mold Testing and Remediation questions, answered by experts

Odors, humidity problems, and health symptoms like headaches or allergies.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

If you’re unsure whether you have mildew or mold, you can hire a professional to test the material. The mold inspection cost can range from about $300 to $1,000, depending on the size of the growth area. Once the testing professional tells you whether you have mold or mildew, you can then take the necessary steps to get rid of it.

The duration of mildew smell in carpets depends on several factors, including the extent of moisture, cleanliness, and ventilation. If promptly addressed, the smell can diminish within a few days to a couple of weeks after thoroughly drying and cleaning the carpet. However, in severe cases or if not properly treated, the smell might persist. Persistent odors could indicate deeper mildew growth, requiring professional cleaning or, in extreme cases, carpet replacement to completely eliminate the smell.

Black mold appears in areas with constant moisture and has a slightly fuzzy texture. It’ll have a primarily circular pattern. While it’s known to have a black color, it can also appear dark green, or dark brown, although a few types include orange or white flecks. Identifying black mold is important because people who inhale the spores could suffer respiratory issues or neurological problems. Black mold is a toxic material and requires a professional to remove it.
