"Richard Gray and his daughter Jayce, also a certified environmentalist, were punctual for our appointment and very thorough with sample testing and air quality testing. They were very patient in explaining their process and answered all my questions without hesitation. I would highly recommend them to anyone seeking air quality testing and mold abatement."

"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!!"

"The company sent a packet with instructions to provide samples from two sites. We returned these in the Priority envelope provided. Within a few days we received an evaluation of the mold. It does not appear to be a serious problem. I would have graded this work higher if the company had provided general guidelines for remediating the problem. We were relieved to find the problem not serious, but would have appreciated more clarity, such as a simple page outlining safe and unsafe do-it-yourself procedures materials materials. (Suggestions I found online, such as whether to use vinegar, bleach, etc., were sometimes confusing, even contradictory.)"

"I suspected the presence of mold in our first floor due to an allergic reaction and a previous leak in the area. John Riera and his son came, took moisture readings and air samples. In addition, John was able to troubleshoot and provide other possible causes/solutions to the allergies. He produced a detailed report with good advice. The service is pricier than other mold inspection companies, but I like that there is no potential conflict as he does not do remediation, and that his expertise extends to other chemical contaminants."
