"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!!"

"Overall, they did a good job. They are friendly and very helpful. we had a little mess to clean up after, but to be fair, I didn't complain -- if i had they would have come back. Preferably they would have come back to check on their own."

"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 questions, answered by experts

Not necessarily. If the mold is only on the surface or in small areas, you may be able to clean it effectively without removing all the caulk. However, if the mold has deeply penetrated the caulk or the caulk is damaged or deteriorating, you should remove the caulk completely and replace it to ensure thorough mold removal and prevent future growth.

Yes, brown spots on a ceiling are usually caused by water leaks and can lead to mold growth, especially if you don’t correct the underlying problem. Ongoing water leaks and moisture issues will almost always result in mold growth, especially if you live in a warm climate. Mold is a health hazard, so get the root problem fixed quickly, clean it, and encapsulate the area to avoid mold formation.

Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. 

While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.

You can find the smell of mold in your house in two ways: following your nose, and using common sense tactics like looking anywhere there’s water first. Mold cannot form in a completely dry environment, which is why you see mold much more often under kitchen sinks than on garage floors. If you have looked everywhere and still can’t find the source, hire a pro, because you may have mold in your walls.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.
