"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. "

"Eran and his team were great. I had agreed to remodel my bathroom before moving in to my new house. It turned into quite an adventure once structural problems were identified during demo. Eran worked with me on trying to keep the bathroom timeline on track as I worked to get other contractors in to fix the other problems.  And they worked above and beyond in motivating me when the other contractors were late. We did run in to a slowdown at the end of the project and better communication would have been recognized - the problem was with a supplier outside of Eranâ s control. The end result was a slip at the end date for the project. Once everything worked out, I was very happy with the end result."

"This is my first time leaving a review for a company as I've never felt the need to, but using Pacific Environmental I feel I should share with my home owners. My husband and I bought out first home which we love but a room had acoustic ceiling. I reach out to PEAS, which everyone in the office was very helpful and patient on guiding me through this experience. Their scheduling was amazing as I was dealing with Closing Escrow and moving my family in. Once they arrived, they informed me on the scope of work and what they would be doing and what to expect, this being my 8-year-old son room so I was a bit worried on hazardous material that was being removed and used. CONTAINMENT WAS AMAZING! I was so happy and felt so safe on how they kept the area and the protection they took to take care of my family and themselves. My kids thought the crew looked pretty cool too, haha. CLEANING WAS AMAZING! Work was conducted upstairs and they went the extra mile and cleaned everything they touched, I really appreciate that, as it again made me feel secure and safe. PEAS left a memorial memory our kids still talk about. I strongly recommend them and would use them again."

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

No, heated floors are unlikely to cause mold. In fact, they can help prevent mold growth. The additional heat helps dry excess water and reduce condensation, which can lessen the likelihood of mold growth. Additionally, the heated floors can help reduce humidity near the bottom of the floor.

Determining if vermiculite contains asbestos requires professional testing. Visual inspection alone cannot confirm the presence of asbestos fibers, as these fibers are so small that they are not visible to the naked eye. A certified asbestos inspector will collect samples of the vermiculite insulation and send them to a laboratory for analysis. Microscopic examination using polarized light microscopy (PLM) or transmission electron microscopy (TEM) is necessary to accurately identify asbestos fibers. DIY sampling is strongly discouraged due to the potential health risks associated with asbestos exposure.

It‘s risky to pressure wash indoors, and we wouldn’t recommend it, but following all safety guidelines can prevent the worst outcomes. Always make sure to use an electric-powered machine over one that’s gas-powered, remove obstacles that could cause tripping or falling, and keep appliances like hair dryers and toothbrushes unplugged and out of the way to prevent electrical hazards. 

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.

The microscopic asbestos fibers do not cause eye irritation, throat irritation, or lung irritation. If you are inhaling fibers, you will not know it. This lack of immediate symptoms is one of the reasons why asbestos is so dangerous. You cannot know for certain if you are inhaling fibers, which is why you must wear safety gear if you could have any chance of an exposure while working.
