"They responded very quickly and sounded very knowledgeable. The test results were sent the following day. This is a minor thing but the inspector talked in technical terms which I did not understand. I wish he could have explained more. However, on the report I received all the technical terms were clearly defined in a way I could understand. A suggestion would be to provide the customer with the explanation of thes terms at the time if the inspection or talk to the customer in terms they can understand."

"My review is tiered because the overall service seems to run on tiers. The technician was great. Very personable and professional. 5 stars for his work. Your tests get sent to the lab. The lab explains the results and recommends a company for a DIY solution. This is where things start to fall apart. The company you get referred to has abysmal reviews and the sales pitch feels extremely predatory. That taints my opinion of the lab results which would be teamed up with a business they probably shouldn't recommend. We're planning on either an independent company locally to get a quote from for any remediations we will take or even see what home depot has to offer. In any event please read the reviews of BioCide, the company they will recommend you use. We're still not sure we even have a real problem if they are working together."

"I called on Thanksgiving day and Chad (owner) responded that day and was able to come out to assess the issue the next day. He and his crew were very respectful of our belongings that had to be moved to deal with the mold. I would hire them again."

Mold Testing and Remediation questions, answered by experts

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

Any unexplained smell in your house should be investigated. However, some home odors are "red flag" worrisome because they pose immediate health and safety risks. Odors should be taken seriously when accompanied by headaches, nausea, or lightheadedness. If you smell an egg-like aroma, this is probably natural gas. You should leave the home immediately, and  contact your gas company.  

Mold in air ducts releases spores into the air, which cause allergic reactions and respiratory issues. Common symptoms include coughing, sneezing, or itchy eyes. Prolonged mold exposure can lead to more serious health issues, especially for those with compromised immune systems.

Toxic black mold on wood appears as dark green or black patches. It often has a slimy or wet texture and may spread across the surface in a spotty pattern. The affected wood might appear discolored, soft, and damp. Identifying black mold early is crucial because it can cause severe health problems when its spores are released into the air. Prompt remediation is necessary to prevent further damage and health risks.

You’ve stored your coats away all summer long, but now that the temperatures drop, you notice they smell weird as you pull them from storage. What’s the deal? If your clothes smell weird after you stored them, they may have been in a moist, dark environment for several weeks or months. This environment is ideal for mildew growth, which can make clothes smell musty.
