David did an amazing job inspecting my home! From the moment he arrived and throughout the rest of the inspection, he was very professional, conscientious and respectful of my space while I was working from home. He was exceptionally knowledgeable and extremely detail oriented. He asked many questions and educated me during the process. His attention to detail, integrity and genuine concern for his clients set him apart from others. I highly recommend him to anyone who's looking for a trustworthy and knowledgeable mold inspector!

Our experience was Tim was a fantastic one. He was thorough, respectful, and very knowledgeable. He took the time to answer all of our questions and explain the science behind the tools he was using so that we could understand the evaluation process. We highly recommend him for your mold inspection service! read more

Bryan was respectful, highly competent, explained everything well, and did impeccable work. Very good experience, totally recommend. Not a nice problem to have but Mold Inspection Sciences are the right people to consult for help assessing and addressing it! read more

The LAST thing I wanted to hear was that we had mold in our basement and company coming in a month. Mold Inspection Sciences came quickly, did a fantastic job job with caring, knowledgeable people. They treated me like I was a member of their family. We even got the final report back sooner than expected so now I have more time to get ready for company. I'll be honest- I hope I never need them again. But if I ever have another mold problem, I have them on speed dial. Signed- a VERY satisfied customer read more

My mold inspection with Tim Ruddy was great. He was thorough and patient, explaining to me what he might be looking for and answering additional questions I had. We discussed what made sense in terms of what samples to test for which I appreciated that he understood my concern for mold and desire for peace of mind but also that I didn't want to go overboard, unlike some other companies that might take advantage of worried customers. It is also reassuring to deal with someone who is not only trained, but has many years of experience on the job. read more

I had mold inspection of my house. Tim explained the procedure and kept me informed of the progress.

David was very professional and thorough. He took the time to sit down with the family and discuss the challenges that we were presented with. read more

Zander did a thorough job with testing and explanation. The report they provided is helpful as well. A visit fee covers up to three different "areas" of the home, and accounts for the air within 6 or so feet around. Expect to have to pay for specific sample collections (yes, more than one) seperately from the visit price....it does get a bit more costly than I would like. But I trust their work. read more

Highly Recommended: MOLD Specialists Who Have Inspections Down to a Science! We recently hired Tim from Mold Inspection Sciences to come out to a 3500 sq. Foot 50-year-old inherited home in South Orange County. We are currently performing our due diligence in preparing the property for sale, and investing in this type of specialized inspection is simply the smart thing to do. From start to finish, Tim was fantastic. He was on time, friendly, and highly knowledgeable. What we appreciated most was his communication style--he handled all of our questions with absolute ease, explaining the technical details in a way that was clear and easily understood.  When we received the final report, we were blown away by how comprehensive yet easily understandable it is. Rather than a simple pass/fail summary, their reports are incredibly detailed and leave no stone unturned. They include:  An room-by-room physical and visual assessment breakdown.  We did not have every single room tested, but we tested any suspect areas where we could see there had been prior leaks. Moreover, their thermal imaging equipment can spot leaks that we could not see. Detailed ambient indoor air sampling alongside localized outdoor baseline controls.  Advanced wall cavity core sampling to actively look for hidden moisture issues.  Direct surface swab testing of several suspect areas. Exact diagnostic tracking data, including localized relative humidity levels and digital moisture-meter readings.  Yes, humidity over 5k or 60 percent makes mold grow. You need good air circulation as well as good dehumidifiers when you live close to the ocean. Clear photographic documentation with matching room diagrams and structural descriptions.  We knew of several areas that absolutely needed testing. And Tim was great in suggesting what areas we might want to test for hidden leaks based on his thermal image readings. He also pointed out where such tests were not needed. What makes this company unique is that they are true, dedicated environmental specialists. Because they literally have the inspection process down to a science and utilize top-notch, highly calibrated equipment, their operation is streamlined. As a result, their pricing was extremely fair and competitive--in fact, their rates were actually lower than some generic, non-specialized home inspectors we looked into.  While initially we planned to have 1 company do all the environmental testing, we found it was less costly and better testing to go with specialists rather than "we do it all companies". It was a super-smart decision. We went with Mold Sci (Tim) for the mold testing and a 2nd specialty company for the asbestos and lead testing (Enviro Diagnostics, Costa Mesa). If you are buying a home, selling your home, or managing an estate property, we highly recommend both companies we worked with and would hire them both again. Tim and Mold Inspection Sciences were top-notch... professional, friendly, scientifically thorough, and excellent value. read more

We had an excellent experience with Timothy Ruddy from Mold Inspection Sciences. From the moment he arrived, Timothy was professional, thorough, and incredibly knowledgeable. He took his time inspecting every area of concern and explained the entire process in a way that was clear and easy to understand. This has been a very stressful situation for our family, and Timothy approached it with calmness, integrity, and care. He answered all of our questions patiently and made sure we fully understood his findings and what they meant. His attention to detail and transparency gave us a sense of clarity and security during a time when we really needed it. We truly appreciate his professionalism and would highly recommend Timothy and Mold Inspection Sciences to anyone needing a thorough and trustworthy mold inspection. read more

Christian was very helpful on the initial phone call to set up our appointment. He was very informative on to what to expect and went into great detail on the options provided to us based on the size of our unit. read more

We had the pleasure of having Tim out to perform a inspection on a condo unit we are renting. Tim is incredibly personable, professional and knowledgeable. You can tell he loves what he does! He showed great passion regarding the health issues surrounding mold toxicity. He explained the process to us and showed us exactly what he was working on. You can tell someone loves where they work based on how they show up and let me tell you, Tim personified this. I would highly recommend Mold Inspection Sciences, but in particular, I would highly recommend requesting Tim! read more

Andrew was super helpful! Appreciate his knowledge and for explaining the process. Highly recommend!

I couldn't be happier with the inspection provided by Andrew today! He was knowledgeable, thorough, honest, and spent all the time required to complete a comprehensive inspection/analysis. Well done, Andrew!!! I'll definitely be recommending your company to anybody that I know in need of an inspection for possible mold issues!! Two thumbs up! read more

Very thorough inspection. Tim the inspector was very professional and courteous. I just received my test results and am relived that it came out clean. Great peace of mind to know. read more

Xander did a great job! Thorough and helpful. Glad to have had him. He was on time and did a great job inspecting everything needed

5 stars! Timothy Ruddy did an outstanding job on our mold inspection. He was thorough, professional, and took the time to collect samples properly while explaining everything clearly. No pressure, just solid science-based work. Highly recommend Timothy and the team if you're dealing with any mold concerns--peace of mind restored! read more

I have used this company on couple of other apartment inspections. They were wonderful and very professional to the tenants. This time I used them to test my own home humidity and mold. Their tech, Xander was wonderful. He explained every test to me and made sure I was aware of everything that went on. Will use them again read more

Xander did a great job inspecting the home I'm renting out. He was far more thorough than the inspectors that the landlord and property management company sent over. He did a great job helping me prove out that there are many widespread moisture issues throughout the home as opposed to just focusing on what is visible and what I pointed out. read more

Awful pricing. Way over priced in all of LA county. Not happy at all with this unprofessional conduct of business.

Tim is awesome. This is the 3rd time I asked Tim to inspect - always on time and thorough. He doesn't do anything unnecessary and works with me to determine the best approach for my unique needs/situation. This time, he took the time to explain his findings to the property management and advocated for my health and safety. I highly recommend Tim!! read more

Timothy was very knowledgeable and explained everything he was doing and gave us the best options to fit our budget. Would recommend.

From the start the company has been so supportive in assisting us with our needs, scheduling a specialist to come out to walk us through the process, everything from what the process is, to inspecting and testing, to how we'd receive our results and any next steps that are suggested. Xander, our Environmental Consultant was so helpful, even reaching out before his scheduled appointment to let us know that if we'd like he had completed his other inspection and could head over earlier if that was helpful. We also appreciated how he came prepared with his own show covers, as most often times we have to ask and provide that for any contractors coming through. He was very precise in his approach, his finding and shared what he could do for any or all mold tests we were interested in having done. Couldn't recommend enough. read more

Tim Rudy was amazing! We love him so much. We had him do a second residence of ours the next week. I was so worried to hire someone for mold inspection just assuming they were all scamming. Tim is so knowledgeable, very professional and offered great resources beyond just mold detection. We love him so much. I shared his name with our realtor to share with her clients!! Good work, Tim keep it up read more

Erwin was great. He really walked us through the process and identified potential areas for concern and where we shouldn't be as concerned. We tried 3 other service providers, and they tried to sell you everything. We could tell they were not sincere in their evaluation. Erwin was the exact opposite. Very experienced, thoughtful, and helpful. He helped us choose where we needed additional testing. I would absolutely use Mold Inspection Sciences again since they keep people like Erwin on staff. read more

Xander was incredibly insightful and helpful. It was great to be able to talk through complex issues with him; he clearly has a depth of knowledge and passion for public health. He came to check out potential mold issues in my apartment, and I felt lucky to encounter his warmth, attention to detail, and expertise. Would highly recommend! read more

These guys are a whole vibe if you really want the experts to show up and get the job done above and beyond, they patiently take the time to explain everything (and painstakingly, upon demand) and are really a pleasure to work with. They show up with enough people making a seamless approach viable. I was made aware that they were training so I'm guessing they usually need one less person, but I was impressed that they sent more than one because the last company I hired sent one and he was incapable of completing the job solo because to do so would put him at risk Going Into compromised crawlspace areas Very impressive attention to detail and trustworthy; I felt comfortable leaving them in my $2M condo and trust them to assess my mold risks competently! I'm super stoked to update this review when I see the results. read more

Mold Inspection Sciences - Home Inspectors Near Me

See all

The worst there is in customer service. We booked them. We prepared the rooms for the inspection. We slept in other places so that the room will be closed as instructed. We waited for the to come. They didn't show up at the assigned time. We called and they told us there was a mistake and they double booked. We spoke to Katy the manager and she apologized but absolutely refused to correct the situation for today. We asked she call the other client to movve their time because we are gone and allocated the day to this impsection and her refusal to meet us half way and send someone today was so aggrevating that I told her to burn in hell. She was stubborn beyond my understanding. Here is a woman who has zero solutions to a problem. I've been a marketing director all mmmy live and have always found solutions to accomodate clients. But not her. read more

As a contractor and architect specializing in the renovation and restoration of large period homes across Southern California, mold and moisture assessments are a routine and essential part of our early project stages. I've worked with many technicians over the years, and I consider myself fortunate to have crossed paths with Christian for a second time on one of our current sites. Christian is a standout professional. He brings not only deep technical knowledge, but also a rare ability to communicate effectively with building professionals. He understands our goals--both the urgency of immediate remediation and the importance of long-term preventative strategies--especially on multimillion-dollar homes where proactive planning is critical. He was punctual, courteous, and carried himself with professionalism throughout the inspection. read more

I am glad I went with this company, and I am certain their report will be beneficial in getting more thorough remediation and stronger claim against insurance. read more
