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"

Pacific Environmental & Abatement Solutions Inc
Pacific Environmental & Abatement Solutions Inc
Southern California's highest rated abatement Company. Additional DBAs - Pacific Environmental & Abatement Solutions Inc. & P E A Solutions.
"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."

20/20 Advanced Property & Mold Inspections
CRMI #13322 CREIA President, Orange County Chapter ASHI President, Orange County Chapter CREIA Inspector education provider .Master CREIA Inspector - #0086 .ASHI Certified Inspector - #249392 .CRMI (Certified Residential Mold Inspector): (ACAC) American Council for Accredited Certification .IAQC (American Indoor Air Quality Council)-#13288 .Certified Radon Measurement Provider,CDH (California Department of Health Services) #102017RT
"Mike Cantor (20/20 Advanced Property & Mold Inspection) was referred to us by a family member when we recently brought a home. He is the absolute best, most thorough, and professional inspector we have worked with. Mike responded immediately when we contacted him for a home inspection that we wanted done ASAP because of our short escrow time. We were able to set up the inspection in the same week. Mike arrived early on the date of inspection around 8:45 am (start time was 9:00 am). He requested about 7 hours to perform the inspection which caught the owner and realtor both by surprised as most home inspector only gave a cursory 3 hours inspection. Mike was meticulous in his inspection and took time to points out many aspects of the house's construction, remodeling, and reconstruction that we were unaware of. He was extremely detailed in his inspection and documentation with videos, still photos, and even drones (to inspect the roof). Mike was still going strong around the 7th hours which irked the seller/ realtor but was extremely favorable and reassuring to us when we are making such a large purschase/ investment. Mike is a little bit more expensive than your run of the mills home inspector but he is worth every pennies and more. He ended up discovering multiple issues with our house that were not apparent to us on our examinations. We ended up negotiating with the owner to reduce the sale price by $40,000. Mike continued to help us with recommendations after the completion of the inspection on vendors (termite, landscaper, roofer, etc) who he felt were reliable. We can honestly say that Mike Cantor truly loves his work and he is the only inspector we are going to use or recommend going forward. Can't thank you enough Mike."

"Overall experience Terrific. Joseph is one of the most honest, straight forward guys out there. I am very thankful with God that he leasing me in the right way so that I would choose his company over the other companies out there. I’m the beginning I thought that the price was a bit high for my budget but then later I realized the skill level that he does in each one of his kinds of inspection he offers is unbelievable. I owe Joseph my life he helped me convince myself that there truly was a serious mold problem with the house that I just bought not even 1 year ago. So I moved out from my new home in the mean time before my health continues to get in more delicate situation. The mold odor has now begun to cause me to have asthma which I never ever had before in my life. The bank/ realtor Home inspection report of the home never caught any of this bad mal fowl odor and mold infestation from underneath the home. It’s crazy how some of these home inspection still are able to keep their business license when they are worth no good at all. Trust me you won’t regret yourself by choose Guaranteed Property and Mold Inspections. They are by far the best out there.

"Angel did an amazing job pumping out over 6,000 gallons of water from under our house! Diego came out very quickly to initially assess the damage and then Angel and his team started pumping the water out just a few hours later. They worked hard from 8pm to 2am! Angel was so kind, professional, and helpful throughout the whole process! He responded to all my texts so quickly and communicated with the office for me to get all the documentation that my insurance needed. He even followed up to make sure I had everything I needed. Angel came back multiple times to check on our house and make sure everything was drying properly and that there wasn't any further damage.
