"Did you know mildew is the gas given off from mold?? Joe offered great advice about the growth of mildew into mold, and my landlord's responsibility to remove it. I feel that he is knowledgable and would perform a thorough inspection. Based on my present economics and quotes from 2 other firms, and not to discount Mold Testing CO at all, I decided on another company. Joe at Mold Testing CO is definitely my second choice."

"For clarification, the project was mold mitigation and restoration, not testing. Scott (owner) was great, able to jump right on the project and complete in timely fashion. The final cost was several hundred dollars under the initial "worst case scenario" quote."

"All and all they were professional on time and I really needed to know the answers I got. But it would have been nice if they had encluded the radon test, for the price paid! Also I was told they would help me all the way through even with resources and med. if needed. To good to be true. Maybe a little."

Mold Testing and Remediation FAQs, answered by experts

Mold inspections are worth it because they can catch troublesome mold problems early before they get out of hand. It's worth it to address mold problems as soon as possible because mold can be hazardous to your health and cause damage to your home and its belongings. Mold testing and inspections are the best way to know if you have a mold issue in your house.

While bathroom mold, commonly known as black mold, does not produce harmful mycotoxins, it can still pose health risks. If disturbed, mold spores can become airborne and potentially cause allergic reactions, respiratory problems, skin irritations, and other health issues. This is especially true for individuals with allergies or sensitivities. While bathroom molds are not as dangerous as other mold species, prompt action is crucial to mitigate health risks and prevent further spread. 

Slime mold can thrive for weeks or months in the perfect environment, but that rarely occurs. The mold will typically die within a week of you noticing it. However, it could be dead long before it disappears, and since it’s safe to handle, it’s easier to get rid of it all at once. This eliminates its chance to spread, and also won’t leave you looking at decaying slime mold.

If you notice increased energy bills, poor airflow, or frequent HVAC system issues, a professional assessment is advisable. Technicians can identify duct leaks or inefficiencies that require updating or maintenance.

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.
