Our third and final mold inspector...these guys found the mold when the first two inspectors failed. Very very grateful. They are expensive but worth it. read more

Having felt sick for months in my apartment without much explanation, I decided it was time to hire a mold inspector- and I'm so glad I found Mark. The first thing he wanted to do when he came to my apartment was sit down and listen to my concerns and thoughts regarding the inspection. I have never hired anyone who actually made the effort to listen like Mark did. I decided to do an ERMI test and I'm so glad I did- He was very thorough in his inspection and he saw things that I hadn't even noticed. His attention to detail was impressive to say the least. Once I got my report and I had a phone consult regarding my results, Mark explained EVERYTHING, was very patient with me and my concerns, and he helped me formulate a plan of what to do next..thank you Mark!!! Highly recommend!! read more

The Mold Guy has changed their prices to $2500 for the first visit. It's unfortunate that because they do good detective work, they are going to charge astronomical prices which push out working class people. They are taking advantage of people who are sick and desperate by charging that much. They are now like all the other people working in mold who prey on the scared and immune compromised. They are making it impossible for regular working class people with children to get help because we can't afford these prices. Brian, you should be ashamed of yourself. You're ego is out of control. read more

While they appear to be very competent, I felt I was taken advantage of by spending several thousand dollars for them to do some dust samples and send them to a lab for analysis. I already knew my house had mold since my doctor had tested my body for mold, and the test came back positive for several species of mold. The Mold Guy was recommended by the doctor's office as very skilled. I scheduled an appointment . On the day of the appointment, my gut said "I don't have the money to spend on this right now on mold test of house" (I was so sick, I was already out of work). I told the Mold Guy when he showed up I didn't feel like doing the inspection right now, and asked him how much he "trip fee" was if I were to pay him and he just leave. He never answered that question, and kept talking. He was calm not overtly pushy, but persuasive. I spent several thousand dollars to find out my house has mold (which I already knew since my body had mold) but he didn't do any investigation at all as to where it was. Others who spent thousands of dollars told me The Mold Guy spent spent half a day or more digging and probing the house to determine where the mold was, and they received an extensive report. I received lab test results, but no report. I've looked online, and the cost of the 3 lab tests together would might have been around a thousand, but I was charged way more than that, which is why I feel taken advantage of. I do believe they are very skilled in their trade. If you are considering them, just make sure you (a) have thousands of bucks set aside for the mold testing (b) money set aside to do the repairs (c) you talk w/ them on the phone before they drive out and have them line item exactly what they are doing and the cost of each line item. If you are not ready to do the repairs, probably better to hold off on doing the mold testing of your house and just have your doctor test your body for mold. If your body has mold, then you are on the tough road of figuring out if the mold is from the air around your house, your house, your car, your work location, your food, your water, your vitamins/supplements). p.s. I did speak w/ a fellow patient at the doctor's office and he/she said they had one mold tester, that was pretty sloppy, he/she then hired The Mold Guy and Mold Guy found stuff the other guy missed, and she was really happy w/ The Mold Guy's work. read more

The Mold Guy is an alarmist. He will tell you that your house is falling apart when it isn't and there is mold everywhere and scare the heck out of you. He has a bad reputation and I regret ever using this company and spending the money. Stay away. One of my greatest regrets was hiring this company. He has cost me unnecessary stress. read more

The Mold Guy changed my life. I had been extremely sick for 6 months with chronic mysterious illness. After two mold inspections from other less thorough companies, Brian Karr with Mold Guy finally inspected and found the mold (hiding) in our home and I moved out the next day. I then began my long road to recovery with my doctor who referred me to him as she had used him. They are very expensive, but you can't put a price on your health. Highly recommend this company. They are extremely worth it. read more

Sold me on a treatment plan that I didn't need. Preyed on my fears. Very sorry that I didn't research his methods more.

If I could give more than 5 stars, I would! I am totally amazed at the kindness, generosity & professionalism of Mark. RIght at the holidays, Southern California encountered some of the hardest rains in years. These rains caused our power to go out in our house, and the delay in our landlord resolving this issue then caused a mold issue because of the lack of ventilation. Currently, our roommates and the landlord are in a serious conflict over the resolution of this issue, but at the moment, any repairs are coming out of my pocket. So, I called "The Mold Guy, Inc." with literally $20 cash and the serious need for a professional to help me verify that the mold is because of the rain, not our negligence. After consulting with me for over 30 minutes, Mark came and visited my house to take a look at the mold. When I tried to offer him the $20 that I had, he refused. This is community service at it's finest here folks. Here I am, a 20 something year old girl in L.A., being threatened and pushed around by our landlord, and Mark takes time to provide his services despite our finances. I am so grateful and if I ever need mold samples taken, he is the only one I would call. I urge you to give this person your business as well, as this type of person helps make communities better. Thanks Mark! read more

I felt totally ripped off and a delicate situation was accentuated by these folks comments to a tenant. For a recheck i used Decker Environmental - they were faster, matter of fact, helpful AT 1/3 LESS THE PRICE. This was an expensive lesson. BUT I WAS THE ONE WHO PAID THE PRICE. read more

We had health problems for months and the doctors couldn't determine what was wrong with us. As a last resort we figured we'd do a mold test on our house and I am so happy we did. Mark was extremely helpful and through on his inspection. He was understanding and considerate of our situation. And he found traces of 3 different molds (one of which was toxic black mold) in our house, all of which are toxic to people and our poor little dog. I had no idea there were so many kinds of mold that could cause extreme health problems. Mark was able to come out the same day to do the inspection and got us the results ASAP. He even called us prior to the final results coming in to warn us not to reenter the house. Thank you Mark!! read more

Here's the bottom line on The Mold Guy aka Mark: he saved us from buying a property that would have made us sick. That is a priceless task. His tests are seriously professional, his communication is excellent, and his level of knowledge on the subject is incredible. Mark spent hours of his time explaining mold-related issues to me before I ever agreed to hire him, and was spot on with communication before, during and after our purchases. You always want to do business with the owner of a business, and having Mark on your side means you'll get service far and above some bigger shop that will send out Steve The Employee instead of the owner. A++ and THANK YOU, Mark. read more

The Mold Guy is as professional and thorough as you get when it comes to industrial hygienist and testing. Jason spent a lot of time talking us through everything and made sure we understood why and what needed to be done. There was no pressure, and Jason did not hesitate for a second to answer all of our questions. Mark also spent quite a bit of time on the phone with us after we had our results in. They are definitely very knowledgeable and have a true passion for what they do. While I wish nobody to ever have the need to use their services, if you do, I recommend them. Thank you Jason and Mark for your help during that difficult time. read more

We hired The Mold Guy to come and inspect our home. He did a very thorough job and my wife said they were professional and thorough. However, he completely freaked us out. He said someone in my wife's condition should never live in our home. He charged us $2500 JUST FOR THE INSPECTION and wanted another $4k to run the test from all the areas he looked at. I had another mold guy test a year before and he found nothing. My wife has immune issues so we're hunting for the problems. I didn't feel good about a $2500 inspection fee and another insane bill for tests (he's going to reply he discloses his fees up front, but I honestly didn't know NO tests would be done for $2500). So, I got TWO other opinions. After $2000 in tests we found out... NO MOLD, NO TOXINS. NONE. This guy almost freaked us out into selling our home. His reputation is an alarmist who over charges for tests and suggests insanely expensive remedies. DO NOT USE THIS SERVICE. read more

Talked to Mark about my potential mold problem and received great advice that didn't include the company's services. Above and beyond professionalism! read more

I am so grateful to the staff at the Mold Guy and Jason who has helped me in two different houses. I was originally deterred from using The mold Guy since they stated they are more extensive in their testing and charge more than most, and it could cost 2-3K for an inspection - I thought that was/seemed unnecessary. However, inspection fee is around $600 and then whatever tests they need to do is charged for each test. You can speak to the Inspector so that you are mindful and strategic of what tests to take though. As a renter it is not worth it to do very extensive testing, if your landlord is willing to let you out of lease - and if that's your goal, which the landlord usually is inclined to do when there is a mold problem. I still highly recommend having an inspection done by the Mold guy and paying for the inspection yourself as you then own the report -for legal purposes. Because not all mold inspectors are created equal. There are many bad fish in the sea. I was totally screwed by another inspector, whom I had used in a previous building, I thought he was trustworthy so I had my landlord arrange and pay for him. I had no idea this inspector, not the Mold Guy, would end up changing his opinion based on who paid him. His inspection was $1,200, that my landlord paid, and despite lab numbers off the charts he said it was safe to live there. Then I had the Mold Guy come to do an extensive second opinion inspection for $1,700, reviewed the testing done by the other guy and confirmed the massive problems. Not that big of a price difference either if you think about all the money this has cost my health, and the samples the Mold Guy took from wall cavities vs. the other guy who took pointless ambient air samples. It is very easy for the landlord to hire shady mold inspectors who do ambient air samples that show nothing, and say there is no mold problem. Even though mold is in 80-90% of all buildings in LA. I highly recommend anyone suffering from mold to do an ERMI test yourself first (which is trustworthy, it was literally developed by the EPA) educate yourself by listening to moldfinders radio podcast with Brian Karr, and finally call the Mold guy for an inspection for your sanity so you can 100% know where the issue is, for legal purposes if your landlord has been negligible and as a result you have incurred medical problems and costs, and whether to decide to ask for remediation or to move. I wish I would have just done this from the beginning, it is certainly what I am doing now and will continue to do from now on. read more

Mark is very helpful,professional,informative and friendly. Really took time to access my situation and had valuable information that many other mold inspection companies either don't know or don't care to discuss with you. 5 stars. read more

There is not enough space on yelp or enough words to express my gratitude and thanks to Mark Levy. Several weeks ago, we rented an older home built in 1952 in the Rancho Palos Verdes area. Because of its location and quality of schools, this area is in high demand. As such, I never imagined or thought there would be the problems that Mark uncovered during a mold inspection. The reason I called Mark in the first place was because of a large amount of black mold that was under the sink against the back wall upon move in inspection. Despite my realtor's remarks that all houses in the area had mold and could be cleaned with soap/water/bleach, i had an uneasy feeling and called Mark on a Friday afternoon to inspect the property the next day. The reason for our move to this area was because our 2 year old son has asthma and his doctor recommended we move out of the SF valley to the beach area where the air is cleaner. What Mark found as he inspected the house was horrendous. He discovered addtional areas of mold throughout the kitchen, appliances and furnace. There was also extremely high content of moisture in the walls. The attic was a disaster - extremely dirty, covered with asbestos, including the vents. The exhaust from the bathrooms were directed into the attic (apparently a big no-no in construction) as well leaving more mold deposits. Right there and then an there, we knew moving into this home would be extremely dangerous and cause irreversible health issues for my son. Upon completion of the inspection, Mark recommended testing to confirm our suspicions. 3 days later, we had the verbal results of the test showing that the home did indeed contain toxic mold - SEVERAL kinds. 2 days later he had a written report and lab results that showed the home held dangerously high contents of black toxic mold. I can't even begin to think what would have happened had Mark not been so kind to inspect this home for us at the last minute. He was genuinely concerned for our family's safety and our healh and went to great lengths (even working over the weekend) to ensure we had the documentation needed to terminate our lease. The scary part of this whole situation is that the owner was made aware of the issues and claimed she had the home remedied in just 2 days - which, is impossible as the entire kitchen needed replacement along with the ventilation system. Without a doubt, Mark is the best and I can't recommended him highly enough. I think Mark is probably one of the most genuine and caring people I know. His expertise and experience in his field is exemplary. I will NEVER move into a home thqat is not brand new without Mark's inspection first. Thank you , Mark! read more

Thanks to Mark from The Mold Guy, my daughter's health is back to normal. Honest, compassionate, professional, thorough, 4 words that easily describe the guys of The Mold Guy! My daughter was getting sick quite frequently, I decided to have my apartment inspected for mold. Sure enough Mark uncovered mold, which my landlord then repaired...or so we thought. After about a year she started getting sick in the same way again. So I called the company that I knew would be honest and tell me the truth. Again there was mold, at first the landlord didn't want to repair it stating it was previously repaired. Mark wouldn't allow that, he provided me a thorough report again, took the time to talk with my landlord, and provided a list of mold remediation companies for him to call instead of having his 'people' do the work. No more mold! read more

Contacted jim at mold guys and highly recommend this company...service was fast and efficient price was reasonable and cleanup.was spectacular thank you so much for your help in cleaning up my mold problem...carol read more

I had the Mold Guy come out to assess my property for mold a little over a year ago. I had read all the rave reviews and was really eager to finally figure out what was going on in my house. I thought they would help me dig into the causes but that wasn't the case. They just pointed out all the potential things that may be an issue. I had another inspector come out before and I thought they would be much more thorough so was willing to pay their steep fees but after everything just felt I didn't even come close to getting my monies worth out of it. For over a $1k I really didn't learn anything new about my home. I was also disappointed that having been a former client, I recently discovered mold during a remodel and called them 3 times, and left voicemails and they didn't return a single phone call. I even spoke to one of the guys for a couple seconds before the call dropped and he didn't even try to reach me back. I tried the office but it went to vm. Just really disappointed. I spent a lot of money with them last year so you would think the least they could do is call me back. In the end, I had to find another inspector to come out. Never heard from them. read more

Jason has inspected two apartments that I've had problems with water damage and he's simply the best! Not only is he an expert and completely thorough with his inspections, but he's also very compassionate given the illness that can come with mold exposure. I highly recommend using the mold guy if you have any suspicion of mold lurking in your home. I can't say enough about how much I appreciate them. Thank you!! read more

I called The Mold Guy in need of help with a mold report I already had. Mark took the time to look at the report via email. He called back and told me what the report said. He took the time to explain to me in plain terms what my family was living with. His price was completely reasonable. He went way above and beyond for us. I appreciated all of his help in our time of need. I would definitely recommend Mark to any of my friends, and I know if I ever have a mold problem who to call. If you're looking for someone to help you with a mold issue, Mark is the one to call. Thank you mark read more

Jason came out on a Saturday and was very thorough and prompt with the inspection report. We thought we would receive it by Wed. That Monday I was already having it sent to me. I was very impressed!! Also they recommended various people who can remove the mold. I am at that stage now where the remedial work needs to be done. But I would highly recommend the Mold Guy Inc. They answered and explained every question and considering my knowledge of mold is at a zero they did a great job making it easy to understand. Even the report. read more

This review is long overdue, but better late than never! Mark is incredible. He is a true gift and I will be forever grateful to him. I had a mystery illness for 7 years before it was finally discovered that my body was toxic with mold. My doctor recommended that I have my house tested and recommended Mark. Mark is highly skilled and very knowledgable about finding hidden mold and also knowledgable about CIRS (mold illness). He found mold in multiple areas of my house. I remediated it, but decided to move due to the trauma I went through there. When trying to find a new safe house, I called Mark again to assess a home which was in escrow. He saved me once again by finding mold and I dropped out of escrow. Thank goodness for him because my healing depends on me living in a safe space. I am now in a safe home and making great improvements with my health. Mark has been a great support to me and he has gone above and beyond to give me helpful tips for my recovery. He truly cares and I appreciate that very much. The testing does get expensive, but when it comes to your health, you want it done the right way and it is worth every penny. read more

If you want to find the most knowable company in Los Angeles for detect mold it rhe mold guy Mark. They are on top of the education of what mold can do to you and how to detect it in your home. If you have water damage in your home or even if you feel sick all the time Mark education me that it could be mold. They inspected my home and gave me a report to get the problem fixed. I highly recommend them as if you think you have mold you most likely do. Thank you guys. read more

Beware! One word - marauders. The most expensive testing and sampling. Most companies charge $50 per sample. Some $25. This company charges $135 per sample fee. Most companies charge $250 for inspection. Some are free. The Mold Guy will also sell you a DNA test your do not need. Also, their recommendations are the most destructive. They find the most expensive way to remedy the problems and then they refer you to the most expensive restoration companies. read more

The Mold Guys have given me peace of mind during a very stressful time. I had contacted multiple companies recommended by my insurance and finding my own resources, but I was not satisfied with any of them, and none seemed trust worthy. Not only are they very knowledgeable and walk you through everything before you commit to their services, but they are extremely reliable and personable, which is so important when having issues like. Brian really took his time to help me understand the issues going on in my house and how it is directly affecting my heath. The news wasn't great about all the mold in my house, but I couldn't be happier to work with these guys as I get my house back to health. read more

Mark is the consummate professional who is extremely detailed. He gave me information on the phone, took time to tell me what the testing process was about and no pressure. Another company was hired and did not follow the protocol Mark had shared was important in detecting mold. I hired Mark after the incompetent testing was done to find out the truth. Mark cares about finding the truth and provides the information so any mold or toxins located in your home can be removed. There is a reason The Mold Guy has five stars, he is the best and can be trusted. read more

If you are having problems in your household with mold or anything that you think might be mold, these are the people to call. They are professional, kind, and do an excellent job; you definitely get what you pay for. Mark and Jason did a great job with providing me what I needed and did it in a timely manner too. Their work is thorough and detailed and I highly recommend them to anyone and everyone. I have never written a yelp review for any other company before mainly because I don't think it is important, but this company definitely needs to be praised for their hard work and great efforts. Please if you need someone to come out and check out your home or living space, do not hesitate to call the mold guy! They will definitely take care of you and you are in GOOD hands! Thanks Mark & Jason!!! -Mandy read more

We had such an incredible experience with The Mold Guy Inc. Brian was our inspector and he went above and beyond. My husband has severe mold toxicity so we take this very seriously. We are so grateful to have found these guys. Highly, highly recommend. read more

I cannot express enough appreciation for Brian from the Mold Guy, Inc. He came highly recommended by a friend. Brian is extremely professional, knowledgeable, patient and dedicated to his work and customers well-being. After having rapidly developed some mysterious health issues and subsequently discovering a black colored mold in my home, I contacted Brian to do a mold inspection. Brian explained the process in detail to me and answered all of my questions. He took air samples and dust samples and did some VOC testing. We ended up having the toxic black mold and other toxic molds. Brian provided a detailed report, analysis and remediation recommendations that also considered health safety precautions. He patiently went over the report results with me. I ended up having to do a series of testing due to additional flooding. Brian was available even on short notice. Brian's customer service and support was above and beyond. The information he provided me with helped me get out of the toxic environment that was endangering my and my family's health. I highly recommend Brian. read more

Mark and Jason of The Mold Guy SAVED MY LIFE!! Literally! I've been so ill since Oct 13, 2016...after numerous visits to many doctors and then the Emergency Room at Cedars Sinai...my brother in Dallas tells me that my symptoms sound like Black Mold poisoning...so I went online and found Home Advisor and put my information into their site...The Mold Guy came up...I looked at his info and THANK GOD that I did...they immediately called me and set up a day to come to my Hollywood apartment and their testing...they even suggested an 'additional test' that that was not in the original price...but was very happy that I did it...and they RUSHED my results so that I could get them back so the building owners could start reimbursing me for my Pet Hotels bills...The Mold Guy found Chaetomium Golbosom mold in my apartment and in HIGH LEVELS...so as soon as I turned this info over to my building they began remediation immediately. I am getting better by the hour...and I RECOMMEND this company NOT ONLY because they are GREAT at what they do...but on top of that...they are RESPECTFUL...Genuine and Sincere...and you FEEL IT!! Don't go anywhere else if you have the unfortunate situation of mold. The Mold Guy is TOP SHELF MOLD TESTING!! Thanks, again, Mark and Jason for your HEART WORK!!! Les Brandt read more

Mark has been so unbelievably compassionate to my family and I. We had a million questions and he took a ton of time out of his day to answer them all. He was recommended to us from a lawyer and we are so glad we went with his company for our mold inspection. He is kind and genuinely seems to care about our well-being. I cannot recommend them enough! It's hard to come across company's like this that actually care about their customers. His office manager is beyond sweet and "knows her mold!" Glad to see they get 5 out of 5 stars! Well deserved! read more

I have been on Yelp for a number of years and never had the urge to write anything on this website. I'm not one to complain about terrible service or bad food when eating out. I usually just roll with it. What has compelled me today to post this is the absolute Professionalism that was given to me when I called Marc at The Mold Guy, Inc. I had the horrible misfortune of encountering mold in my closet at the beach in Venice. I spoke to my landlord and was able to approve Marc to come in and inspect the apartment. Not only was the inspection comprehensive and informative, but Marc had a genuine interest in hearing me speak and was more than willing to bounce ideas and thoughts off of me. I would say that his business will flourish for years to come based purely on the genuine attitude and demeanor in which he carries himself. After the detailed inspection, I was sent a full report and lab report as well. Not even 48 hours later and I had the proof I needed to give to my landlord. She was unwilling to accept the fact that there was a major problem and was (quite frankly) difficult to deal with, so in some ways it's sad I'm moving out of my apartment of 4 years, but with the time and care that Marc provided, my health was always his top concern. I would highly recommend The Mold Guy for anyone who faces the same difficult situation I found myself in. Can't say enough good things about him. Thanks for putting the human element above the almighty dollar and proving once again that there are good honest people in this world! read more

They were friendly, helpful and thorough, though I wonder if mold is so bad why the guy did not wear a suit or consistently wear his mask. Very expensive process for something that is not dangerous enough to wear a mask or outfit for. nonetheless, they did good work and provided a detailed report. read more

Mark is your man! Your mold man when it comes to figuring out how to deal with your mold issue on your property. We had some mold issues in our commercial location and needed to figure out how to deal with it and Mark gave us a very detailed report along with lab results. He follows up in a timely fashion and worked with us to make sure we understood everything we needed to know. Very knowledgable and easy to work with, I would recommend these guys to anyone who is having mold problems. read more

Jason just left our home and I immediately jumped on Yelp to leave him 5 stars. We have not yet received our results, but that is inconsequential. Jason is knowledgeable, professional, thorough, patient, I cannot say enough good things about him. Mold inspections can tap into people's relationships with money, health, family, etc. Jason was understanding and incredibly helpful. We asked copious questions, and he patiently and thoroughly answered each one. At no point did we feel mislead or upsold. We are aware this is not an exact science. We are deeply grateful for Jason's expertise as well as his customer service. I highly recommend this company. *Oh! I forgot to mention Nicole on the phone! Prior to the inspection my husband spoke to Nicole who was wonderful! Very thorough and willing to help. 5 stars across the board. read more

If i could give ten stars, i would! Mark and Brian inspected for mold in a home we had in escrow. As our inspection period was short, Mark made time to come on very short notice. He was beyond thorough and very strategic about where and how he took samples so as to avoid any unnecessary costs. It turned out the house had a serious mold issue, which was missed by another inspector. Mark and Brian patiently spent a lot of time on the phone with us explaining the results and the extensive remediation that would be required for us to move in. Ultimately, we felt the home was not safe for our family. if you need someone to look into mold in your home, i HIGHLY recommend you call Mark. And, if you have anyone in your family with mold sensitivities, there is absolutely no other choice - call Mark and his team to ensure a prospective home is safe. read more

Loui from the mold guy is the best. He is professional and the prices are super cheap. Definitely would use them again. Request Loui he is awesome and beyond nice. read more

I called the Mold Guy into my home because me & my children were having some health issues & sensitivities. We all had been experiencing discomfort for awhile. I was having all sorts of different allergies. Constant sinus problems & even breathing issues. I felt miserable and tried seeking out Doctors. I still didn't feel any better with all the different medications. Some time ago, I had a flood in my basement. We dried it, sprayed it & bleached some areas... opened windows & assumed all was well. All my systems are located in my basement. I finally called The Mold Guy in, wondering if I may have had any issues? Did I have issues!! Mark did all the necessary tests to determine what may have been going on. I had mold traveling thru all my heat & air ducts affecting all that I breath. Ugh! You can imagine... No wonder I was sick. Mark had a detailed report giving me all the information I needed to help my " sick home." He also referred me to the proper remediation companies to rid my home of it's affected areas . He also was kind enough to refer me to some environmental Doctors that could actual understand all my ailments, and help us get better. I'm grateful to Mark for helping my family to get better. It was such a mystery for me & my family. Who would ever think that your house could be sick! But it makes sense! We live & breath in homes that are living systems that also have to be taken care of! I would hire him again & recommend him to anyone that may be going through similar situations. read more
