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"

"My remediation was challenging because I live a couple states away from the house I own. I had received a quote from another company saying that my whole bathroom needed to be torn out. When AM/PM inspected, they suspected that the damage was not that widespread. Sure enough, when they did the demo, the mold had not spread widely into the walls. I appreciated their honesty, even though it meant a smaller job. Maya came to the house to assess the damage, then remained my point of contact throughout the job.

Radon gas testings FAQs

Radon gas is a serious health hazard, as it is the second leading cause of lung cancer in the United States. When inhaled, radon breaks down into radioactive particles that can damage lung tissue. Because radon is odorless and invisible, regular testing every two years is crucial to detect its presence. If you have recently remodeled or started using different areas of your home, like the basement, additional testing is essential to ensure your family's safety.

Yes, you need a radon test to ensure your home is safe. The EPA recommends testing your home for radon every two years and after any renovations. Since about one in every 15 homes has elevated radon levels, regular testing is essential. Including a radon test in your home inspection is crucial when buying or selling a property, and some areas require disclosure of radon levels by law. Don't rely on neighboring homes or regional data; the only way to know your home's radon levels is through testing.

Certified professionals conduct radon testing, including accredited home inspectors and specialized radon mitigation companies. These experts follow strict EPA guidelines and use calibrated instruments to accurately measure radon levels throughout your home. Choosing a certified provider ensures you receive reliable results that protect your family's health and property.Professional testing is crucial for accurate detection and effective mitigation if needed.

Radon inspectors typically specialize in testing and assessing radon levels but may not perform mitigation services themselves. If your radon inspector identifies elevated levels of radon in your home, they will recommend a qualified radon mitigation specialist to address the issue. These mitigation experts install systems designed to reduce radon concentrations effectively, ensuring your home is safe.

No, air purifiers are not effective in removing radon gas from your home. Air purifiers are designed to filter out particles like dust and pollen, but radon is a radioactive gas that cannot be captured by standard air filters. To reduce radon levels, you need a specialized radon mitigation system that removes the gas from your home, ensuring your indoor air remains safe.

While opening windows may temporarily reduce radon levels by allowing some gas to escape, it is not an effective long-term solution. Radon continuously enters your home from the soil, and relying on open windows is not practical or sufficient to reduce levels significantly. To effectively lower radon concentrations, you need a professional radon mitigation system that actively removes the gas, ensuring consistent and safe indoor air quality.
