"This was not the first time using an Air Quality inspection company. They were help full, accessible, timely, accurate, and provided an analysis report that included a representative to review and answer questions. They also provided a referral to a remediation company that approached the issue in an efficient and cost effective manner."

"Shane was my first contact (via phone) and was very knowledgeable and went above & beyond to answer all my questions. I tend to have pretty good discernment, and I immediately sensed I was dealing with an honest, straightforward company. Shane offered me an appointment 2 days later that s fast! Awesome when you re concerned about mold! Ray came to our house (a several hour drive to the Redding area!), and was prompt & called ahead to be courteous. Total genuine and nice guy (especially bc he s a dog lover ;) He wasn t rushed at all, answered all our questions (we had a lot), and actually said he likes & welcomes questions! After we received our report & invoice, I THOUGHT I was messaging my husband, lol, but I texted Shane: Thumbs up! They did thorough testing, & the price was still what was initially quoted! I highly recommend these guys!!"

"They wear masks and are all tested regularly for COVID, which I appreciated. I cannot begin to convey how difficult it was to get rid of the contaminated sentimental and irreplaceable childhood items at my parents' home, and they were so understanding and sensitive to the loss of the items. Their compassion made the process a lot easier for me. The home had been condemned, and due to how meticulous the report was, it was certified as habitable again. I felt like 911 Hazmat was on my side and there to help me, and I found that to be invaluable."

Mold Testing and Remediation FAQs, answered by experts

Homes should be checked for mold annually, especially if you live in an area with high humidity or frequent rainfall. Inspections are crucial following flooding, roof leaks, or plumbing issues. More frequent checks are necessary if your home has a history of mold problems or water damage. Regular inspections help detect mold early, preventing costly remediation and minimizing health risks, especially in moisture-prone areas such as basements and bathrooms.

Yes, it is common for mold to grow on the underside of the siding due to the moist atmosphere. When there is an abundance of moisture, mold has the ideal environment to spread and thrive. This fungus can be found on virtually any surface, both indoors and outdoors. Generally, it is most active when the environment is warm, damp, and humid.

Wood stain is not considered toxic after it dries. The solvents in wood stain are what give off volatile organic compounds (VOCs), which are toxic, but these dissolve as the product dries, leaving behind a non-toxic product. When working with wood stain, you should always wear a respirator and rubber gloves to protect yourself, but once it dries fully, it’s not toxic, according to the manufacturer’s instructions.

You normally won’t see any dust or mold actively floating out of your vent, but you might notice your vent looks dirty. Mold will cling to the sides and collect almost like black soot. Dust will look, well, dusty, but there will usually be a heavy buildup so expect thick gray layers on the bottom and sometimes the sides of the vent. If you suspect you have mold in your vents, call a professional immediately.

While mold in the bathroom can appear black, it isn’t always the dangerous black mold strain Stachybotrys chartarum. This type of mold typically appears after a flood or a long-term leak. If you suspect black mold, you should get it tested by a local mold testing service to determine whether it’s safe to remove yourself.
