All Clear Environmental Inc
All Clear Environmental Inc
All Clear Environmental is Southern California's one-stop solution for asbestos removal, lead abatement and mold remediation. Our team of licensed professionals has over 100 years of combined experience in the thorough, discrete and environmentally responsible removal of hazardous materials. If you think that your property may be at risk for containing asbestos, lead or mold, we can provide you with the most cost-effective solution. And you can be sure that when we're finished, it will be All Clear.
"Abatement and Remediation are not for the weak or weary - whether managing a personal or professional project, proper containment practices and efforts are essential. I will forever recommend and promote All Clear Environmental - a family-run business with hands-on customer relations. Larry Enos and his son, Beckett, put forth great effort to communicate, assess, and manage the process in good faith. All Clear's team of Rigo et al, handled the physical abatement and remediation, in our home. Rigo and his team made us feel 100% safe, confident, and secure throughout each stage - which was no easy feat with children and pets, in a home. And while there are no accolades for being second-round mold recipients, we hit the jackpot in working with All Clear. We have worked with other companies only to be left with poor communication, a tendency to be overcharged, and dishonesty. Beckett was available almost 24/7 to answer questions via text and live calls. When I felt doubt, Beckett made time to discuss alternative avenues and ensure our best interests were at the forefront of every decision. I recommend All Clear Environmental to friends, neighbors, and strangers with 6/5 stars. Your house is your home - and mold is personal. A company that recognizes the need to love your home well, is a gem beyond measure. Thank you, All Clear Environmental - good people attract good people! Gratefully, Jackie"
