"Friendly servicer. However, had a bit of sticker shock with air sampling. Was told it was $160 per sample but it wasn?t clear until she finished that the total would be $320 (a control sample target sample). It would have been better to clearly quote the expected total. "

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"

Mold Testing and Remediation questions, answered by experts

Powdery mildew tends to grow mostly on leafy plants. The mold itself isn’t particularly harmful, except for those who are allergic to mold. However, you should treat it like you’d treat the discovery of any other mold, and get rid of it immediately. Powdery mildew can spread to your home, which can cause expensive damage. 

The easiest way to know if it’s a leak or evaporation that’s causing low water levels in your pool is by conducting the bucket test. However, you can also monitor the chemicals in your pool for signs of imbalances or conduct a visual inspection of the areas around your pool in search of excessive moisture or cracks.

There are different types of mold, and not all humans are the same. For example, a more toxic type of mold may have less of an effect on a healthy person than a less toxic mold in the home of someone who is immunocompromised. If you recognize any symptoms of mold poisoning—sinus issues, brain fog, respiratory distress, constraint cough, migraines, or any others—call your doctor or go to the hospital before you attempt any removal.

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.

Moldy furniture may be salvageable, depending on the extent of the mold growth and length of the exposure. If a piece of furniture is covered in mold and has been for some time, you may want to throw it away, rather than try to clean it. If you're unsure whether a piece of furniture can be saved or not, your best option is to call in a professional.
