John is truly a great business owner that is more passionate about doing things the right way. I had called to schedule a mold inspection but ended up not needing his service. Instead, he provided a incredibly deep education into the science of mold, how mold inspections work, and countered my own misunderstandings on how mold inspections work. As a person with a scientific background, it is easy to tell John cares about doing the work correctly, being truthful, and transparent. If you want honest work, done by someone with passion and with deep knowledge, work with John. I would also like to note that he spoke with me for nearly an hour an even followed up after with texts with citation and more info. read more

John is very passionate about what he does. Quality work. No stone unturned. He did a building inspection and report for us. Very detailed reporting. Very happy with his attention to detail. read more

After reading more reviews, it's obvious that what I experienced is part of a much bigger pattern. The owner becomes hostile and dismissive the moment you ask a simple question. I was calm and respectful, yet I was talked over, corrected, and told that mold is not a health concern at all, which directly contradicts mainstream medical guidance. The consistent theme in these reviews is rudeness, denial, and a complete lack of professionalism toward anyone seeking honest answers. This is not a one-off incident. It's a documented behavior pattern. If you value professionalism, science-based information, and basic respect, do yourself a favor and choose a different company. Previous reply: I want to clarify my experience for anyone considering this company. My interaction with the owner was nothing like what he is describing. I was respectful, calm, and simply trying to understand the situation so I could make informed decisions about my home and my family's health. At no point was I rude, dismissive, or combative. Unfortunately, instead of receiving professional guidance, I was spoken to in a condescending and argumentative manner. My questions were interrupted, minimized, and met with hostility. I was surprised by how quickly the conversation escalated on his side, especially when I was only trying to gather information. I respect professionals who provide clear explanations, transparency, and courtesy. That is not what I experienced here. Anyone reading this should be aware that my review was written accurately, and it reflects the tone and treatment I personally received. read more

We actually did not get a chance to use his services but when I called to schedule service, he texted right back and even offered some valuable advise and information ahead of time without us even asking, which was so refreshing. we will defiantly circle back to him if need service in the future. read more

John was able to help me with my unique situation. His response time is unmatched. He called me back within 5 minutes. He provided a unique insight to the industry and spent the time to help educate me on my specific issue and some things to keep an eye out for. I really appreciated his insight and recommendations and will definitely call him for the next job. Thanks John! read more

John provided excellent insight to this topic and the industry as a whole. He can provide reports if needed that help to document issues.

after seeing john's response, i have to point out that it's strange he's accusing me (and others) of reviewing him without using his services, when he didn't actually give me (us) the opportunity to use them, instead shouting at us that we're foolish for even requesting them. also, i still don't know what IIRIC or whatever is. all i know is that it's strange that someone billing himself as an environmental tester berates potential customers for... requesting environmental testing. i mean, maybe others will have better luck with him, but this was my experience, and i think anyone can tell from my review history that i tend to rain praise upon businesses more often than not. read more

Perhaps the only honest mold detection service around. After seeing pictures, all other vendors wanted to come out and charge me for the visit. Only John said it was obvious from the pictures that it definitely was not mold. We had a long chat (at no charge) and clearly he only does what needs to be done based on science, studies, etc. Many companies are out for the $ and he only wants to do what's best for his clients. He has other businesses which maybe why he doesn't need to charge people unnecessarily. He is so well backed by science that he is often chosen to help clients in court at depositions. This is they guy you want to help you with any mold issues. No one better. read more

John was very knowledgeable and is all about helping protect customers from being scammed by other companies who like to maximize their billings. He was very thorough with inspection and upfront about pricing. Also provided a lot of helpful knowledge. Will recommend to my friends read more

20 stars for john's invaluable wisdom and time he spent informing me, over an hour on the phone of facts about mold and so much more. He is very knowledgeable and could've charged for an unnecessary service but chose to educate me and I'm very grateful. His words are too be valued. Highly recommend read more

Gave me a very honest assessment on the phone about what I needed and didn't need. Super straightforward, candid, helpful. Saved me a ton of money. read more

John is so nice and helpful to speak with. He was very informative over the phone and gave me the facts I needed to hear. I really appreciated him taking the timeout of his day to speak with me. read more

John, wasn't easy to get a hold of but it was worth the time and effort. He's a busy guy, probably because he does his job well and doesn't price gouge like the other 4 companies I had give me a quote. It was done in 3 days and looks like. 5 starsThank you John! read more

Genuinely good guy in this otherwise very sketchy space. Everyone uses scare tactics to grab cash. He talks a lot about how mold is everywhere and grid to minimize because I think he's used to all the crazy worries we all have - so understand that's where he's coming from when he almost excessively tried to calm your fears. We had a substantial roof leak with mold in walls - all handled very well and professionally and nowhere nearly as expensive as it could have been. You won't regret calling him. Genuine good person. Hope he doesn't change. read more

Excellent service and very knowledgeable. John came out and explained how mold develops to a problem tenant. John showed the tenant how her failure to clean had caused the mold to accumulate and he filmed it all on video. The value for the money was well worth it. Thank you John read more

John's team (Josh and Alex) were amazing at the work they did in my guest room and master bathroom. Found all the mold which also uncovered underlying termite issues and moisture barrier areas. read more

John is a no-nonsense kinda guy, and he will give it to you straight up. This industry is very much fear driven. If you follow his advise and look up CDPH (California Department of Public Health) guidelines, they are all there to judge for yourself. I am 100% happy to work with John. read more

John was professional and communicative. He was timely and efficient. There was no obvious signs of mold but there was a smell. He gave us the same advice that mold testings aren't accurate or monitored by any government agency (which we already paid for). He said the only way to see is to open up the wall. He gave a quote and said the price would go up if there was more work. What he didn't mention was that the price would not go down if he did not perform any remediation. His team cut out the wall and there was no mold or even moisture. He said there was nothing to clean or prevent. But he still charged us the full amount of $1975 and he ran a fan and put up a barrier. There was no need for a fan and there was no need for the barrier but he charged the amount as if we had moisture or mold that he had to remediate. While I do trust what he was saying you're better off calling a dry wall or construction to open the wall and then calling John to evaluate because now we need to call the dry wall repair anyways to close up an area that had nothing to remediate. Like I said. Good communication. Knows what he's talking about. But you have a risk of a full abatement charge when there is nothing to remediate. read more

We purchased our home and noticed a smell that the inspection report didn't show. We have experienced a mold issue at a previous house before and we knew we needed to get someone out immediately. We hired another mold company to come out and they did the air sample test and told me that they all pretty much came back negative and we had nothing to worry about. But we still had that feeling that something is not right, so after looking on yelp and coming across John The Moldman, I had to make a call. While speaking to John on the phone, he knew what was going on in our house before even seeing it in person and confirmed the issue once he arrived. It was all coming from our crawl space and it had the wrong insulation that had been saturated for years (even though the inspection report said nothing about this). John and his guys fixed our issue in a timely manner, but also will take the time to know they are fixing the issue correctly. Now we can live in our new home knowing it is a safe place for our health. I would highly recommend John the Moldman for his professionalism, quality of work and value for his service. read more

We recently had our first experience with water leak that damaged on our wall and floor and had no idea where to start. Luckily, we found John among several remediation companies -- and we're so glad we did! Not only is John extremely knowledgeable about mold and moisture, but he also understands construction which gave us tremendous peace of mind. He even caught an issue that might have caused the leak that our plumber completely missed. John went above and beyond by educating us on the common unethical practices some repair companies use that we may face. Thanks to his guidance, we knew exactly what red flags to look out for. Sure enough, one company tried to exaggerate the damage using a moisture meter and even suggested filing a bigger insurance claim for profit -- a huge red flag! John's work was thorough, clean, and efficient. He's honest, professional, and genuinely cares about helping homeowners make informed decisions. We couldn't recommend him more! read more

We highly recommend John, the "mold man," for anyone dealing with water or mold damage. After a pipe burst in our house, we were struggling to navigate water restoration companies and already been scammed by another company that lacked the capacity to complete the project and delayed the restoration. John came in with expertise, professionalism, and integrity, quickly assessed the situation and, at the best price, successfully restored our place in just a few days. He is knowledgeable, reliable, and truly gets the job done right at the best price in Orange County! read more

As a Real Estate Professional I was called upon by a tenant and landlord to address a concern about mold on a property. We called in John The Mold Man and he inpected the property. He told us what to do to get rid of some mold on a bedroom wall. He recommended some small easy clean up, and also corrected the moisture problem that was coming in from the outside wall. Problem solved! He didn't push his own services. He doesn't try and sell you anything. John is very knowledgeable about mold and you will be too! He goes by facts. He does not panic anyone. He educates you how to remediate the problem, and then how to prevent any moisture and mold in your home. John is a voice of reason, he is not self serving, and he is a true professional. I have used him several times and will again. read more

John is straight to the point, transparent, and informative about the mold industry and what to expect. No frills, and is honest about what is and isn't true about mold. I highly recommend and would use him again. He also provided a very thorough report for documentation as well. read more

What an honest guy--I sent him a picture of my issue and he told me how to take care of the problem myself at no cost. For that reason alone, I will call him and recommend him for future plumbing needs. God bless! read more

John the MoldMan is everything you could possibly hope for when experiencing the stress and frustration of a mold outbreak. His knowledge and willingness to address our concerns in comparison to all the other so called experts we contacted was unparalleled. John took his time to listen to what we were experiencing then carefully outlined a professional plan to deal with it. He will discuss misnomers regarding mold in general then offer options on how to fix the problem. My wife and I feel so fortunate to have connected with him The overall experience could not have been better read more

John is the BEST!!!!! He gave me a no non-sense honest estimate of the job and promptly got the work done. He is super knowledgeable about mold and was able to find the problem and get me to the right people to do the repair work to my ceiling and roof in my sun room. DO NOT get work done by other "mold experts" until you consult with John. Other companies instill FEAR over mold issues and end up ripping people off for $$$#. And John is very personable!!!!! If you got mold, you need JOHN!! read more

John the Moldman is awesome and pulls no punches. If you're a bit of a snowflake and can't take real (blunt) talk from a knowledgeable pro, you should probably just call the big names like Jarvis and get taken for all you're worth. Those guys specialize in maximizing insurance claims and use scare tactics and science fiction to maximize revenue. John on the other hand is a straight shooter who provides clear and concise assessments of our issue, a remedy plan, flexible/rapid scheduling, and a fair estimate. We were thoroughly impressed with the results of our clean up, mitigation and rebuild (ALL IN ONE!) from an upper bathroom leak damage. No need to call multiple people for demo, mitigation & rebuild. John is on speed dial for any future leak or mold concerns! read more

Very happy and highly satisfied with John's work! Had some mold issues in the kitchen's cabinets which John and his crew fixed in a timely manner and also cleaned afterwards! John was polite and knowledgeable, and I loved how he took the time to explain everything so I knew exactly what to expect. Highly recommend his services! read more

I am deeply grateful for John's honesty and directness. He helped me avoid the rabbit hole of mold exploration to explain away my health issue. Taking that stressor away is a relief. read more

Found John via Google search and very happy that I found him. John is a wealth of knowledge and definitely loves what he does. Professional, reliable, honest and well educated, well informed. John came to check up on some concerns I had regarding high humidity and potential mold growth in my apartment. Living a block from the beach has its blessings and curses. He reassured me that all was good and equipped me with more mold knowledge than I started out with. John came in with his tools and confirmed what I knew on a more experienced/professional level. I'm sure if he and his team had to do a remediation, it would be well organized and completed nicely. I would highly recommend John to anyone that needed this service. read more

John is your MoldMan! John is extremely knowledgeable not only about mold issues but also the legal aspects of it too. I reached out to John run a mold test of the house because the tenant complained about mold issue. John took the time to go through each issue and tested each issue to show why there was no issue. John also understands the legal aspects of mold complains and was able to generate a report showing why those complains were false. John is also extremely patient when you like go over the issues (or nine issues) over the phone and takes the time to help you understand literally everything. If you need a MoldMan to do your inspections, call John! read more

Wow! What a breath of fresh air, literally, in this very scammy industry. In the last 10 years, I've had 3 water leaks requiring mold remediation. Every company I've used, before John, was all about the money and false information. All they want to do is scam your insurance company and then slap up crappy construction. John is honest and forthright and extremely fair and reasonable. I even referred him to my neighbors who had a leak right after me. I will continue to use and refer John for any mold issues in the future. read more

This is the guy you want. He's so helpful over the phone. He asked for picture of problem and he explains what is causing the issue. Very to the point and knowledgeable. Call this guy!! read more

I had MoldMan inspect my rental property for possible mold issues, and I was very impressed with their service. John did a thorough analysis and confirmed there was no mold present. Even better, he took the time to review with the tenant the proper ways to treat and prevent mold in the future, which was extremely helpful. He also video-recorded the instructions for documentation and evidence. Professional, transparent, and proactive--highly recommend MoldMan! read more

If you're looking for someone truly knowledgeable and honest, John is the person to trust. When I reached out about a leak and potential mold, he not only explained the situation thoroughly but also provided practical solutions and clear recommendations. Thanks to his guidance, I had peace of mind and avoided unnecessary costs. I recommend his services with complete confidence. read more

He was thorough and knowledgeable. I would use him again. Learned a lot. The report helped the tenants understand things.

John the MoldMan is great. If you have a mold problem and you're getting outrageous quotes, he can help. He saved me from overpaying tens of thousands of dollars for unnecessary remediation and gave me an honest, professional mold inspection. Near the end of their lease, my tenant reported extensive mold. My property manager and HOA brought in their preferred inspectors, but the quotes I got were all over the place - one company even quoted me over $40,000! That's when I knew I needed another opinion, so I hired John the MoldMan. From the moment he arrived, John was incredibly thorough. He reviewed the other inspector's estimate, checked every part of the house (even the attic), and explained everything he was doing while recording it on video. He also took the time to educate me on mold, moisture meters, the EPA's guidance, landlord-tenant responsibilities, and what I should expect from my property manager in a situation like this. It was clear he has years of experience in both mold remediation and real estate. Afterward, John sent me a very detailed report filled with photos, videos, and thorough explanations. It included an evaluation of each area of my property, a breakdown of the tenant's responsibilities regarding mold, and a rebuttal of the previous inspector's report - like disproving a supposed "roof leak" that didn't actually exist. In the end, John determined that it was just surface mold caused by humidity - no drywall removal or aggressive remediation needed. He even gave me some bleach and showed me how to clean it safely myself. I followed his advice, and the mold has been gone for well over a month with no issues. John only charged me for the inspection and report (no extra fees, no unnecessary sampling), and his report alone provided way more value than what the other companies offered. I'm really glad I found him on Yelp. I learned a lot, and I'd definitely recommend John the MoldMan to anyone dealing with mold. read more

John has many years experience in the industry and was very patience in educating us about mold. I strongly recommend him as he is the type of guy that will educate you before even taking a penny. read more

John is more educated about mold than the 100 "experts" that I have talked to. I wish I had called him before I paid $825 for a bogus lab to test for mold . He also saved me all the remediation costs because he told me how to do it myself. Super honest and picked up my call on the first ring! At no charge for his wisdom and advice ! read more

This guy is a saint. The most honest, helpful, kind person. I called him in a total panic and he spent a solid 30 minutes on the phone with me for free explaining everything to me and told me not to worry. He is honest and trustworthy, and not out to get your money. Absolutely would recommend him to everyone and anyone! Call him first before anyone else! read more
