"Don Lambert, the owner of this company is a get nice man, and is very informative. He will tell your what's what, and leave you feeling confident in your choice to have hired him. He inspected our new home, and also did an air test for mold (separate service from home inspection) and we can gladly say we recommend him for sure!!"

"There are so many mold remediation companies out there, but NO ONE IS AS GOOD as Mold One! Mike and Ron are compassionate, flexible, and willing to explain everything! They were there for me 100%, every single step of the way, during the most horrific time of my life. My prior mold remediation company had been negligent, leaving me exposed to toxic black mold on a daily basis, and Mold One took care of all of it--with no mess or dangerous dust. Mike was LITERALLY a life-saver. There are so many mold remediation companies charging 10 times as much, and doing a far worse job. It is very difficult to find a company you can fully trust to put your interests first (so many say they do, but when it comes down to it they overcharge or cut corners, leaving you in danger!). I hope Mold One becomes the partner of choice for all the major insurance companies, because they are BY FAR MORE COST EFFECTIVE and thorough than any other company I've found."

"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

Mold Testing and Remediation FAQs, answered by experts

Most grass mold isn’t harmful to humans. Slime molds in particular aren’t toxic and may even possess some benefits. Other molds, like powdery mildew and snow mold, generally aren’t a concern, but can still cause allergic reactions and respiratory distress in those with high allergy risk and compromised immune systems.  

PVC is not considered a hazardous waste in most areas, but regulations vary by location. If in doubt, you should contact your local sanitation department to confirm. The Center for Biological Diversity (CBD) has been working to get PVC classified as hazardous waste, so it’s possible that it will be considered as such in the near future. If it is, disposing of PVC will require the use of a hazardous waste disposal facility or transporter in your area.

The flooring that is the least toxic is solid wood. Natural linoleum, tile, stone, bamboo, and cork flooring also make the list of least-toxic flooring types. These flooring materials are safer and healthier for your home because they are natural materials that aren’t manufactured with chemicals, unlike laminate flooring. While some laminate flooring brands are made with less formaldehyde, many contain high levels of toxic chemicals that can off-gas in your home for months and years after installation.

Choosing natural flooring materials that are easy to clean without chemical cleansers can also help keep your home safer.

Slime mold will go away on its own within a few days to a couple of weeks. Generally, there is no need to use chemicals on this matter. If you want to get rid of it right away, rake over the slime mold and the surrounding area or hose off large patches of it.

Damp air from a humidifier can cause mold in ducts if it raises the air's humidity level too high for the duct system to handle or malfunctions, but it’s not a normal occurrence. To avoid mold trouble, set the humidistat to between 30% and 35% and inspect it often to ensure accuracy.
