Charles has been beyond helpful in checking our home for mold. Methodical, thorough, patient. He has explained everything clearly, listened carefully, been available, kept us calm. Could not be more grateful for finding him. The opposite of corporate! Genuine, human help when needed most! Thank you Charles!
Dear Don and Susan, we appreciate the feedback greatly. It was a joy assisting you both with the moisture testing and indoor air quality testing efforts. I'm glad we were able to connect and work together. You both had very good questions from start to finish. It makes us truly happy to know that we were able to help in some small way. Thank you again and please call if more questions come up! ~ Charles

I cannot recommend Tanjun Mold Inspections enough! From start to finish, he was incredibly kind, professional, patient, and knowledgeable. Dealing with a mold situation is stressful, but Charles made the process so much easier for my family and I. He was patient with all of our questions, explained everything clearly, and went above and beyond to make sure we understood the full report. Communication with Tanjun Mold Inspections was excellent. He was incredibly easy to reach and always on top of everything. He was able to see us quickly, the results came back in just two days, and the detailed report he created impressed us. His pricing is great, too. Charles is hardworking, thorough, and genuinely cares about the people he is helping. When I tell you he is knowledgeable, I mean it. He impressed us with his mold expertise and made sure we understood it as well. He sees you and your family as actual people, and that is an art lost nowadays. Tanjun Mold Inspections will take care of you. Thank you, Charles!
Dear Cindy, it was such a privilege to be able to assist you and your family!
Also, thank you very much for taking the time to write such a thorough review. We're glad that the explanations were helpful because we know it can be difficult to navigate through the mold discovery and remediation process and understand the labs results and ultimately, figure out the true condition of the property. You and your family had excellent questions and we very much appreciate the opportunity to help you become better informed. Again, should you have any more questions, please make sure to reach out. Thank you again for your kind words and support! ~ Charles

Excellent service from start to finish. The inspector was knowledgeable, professional, and very detailed. They arrived on time, carefully inspected the property, and clearly explained their finding in a way that was easy to understand. I felt they were honest and genuinely care about helping me. I highly recommend this company to anyone needing a mold inspection.
Anita, thank you very much for taking the time to leave such a kind and helpful review. It’s always fulfilling to know that we were able to assist in a tangible way . We’re very grateful we had the opportunity to help you navigate through the mold inspection and decision-making process. Thank you again for the recommendation! ~ Charles

We suspected we had mold but to be sure we had our home tested and unfortunately we had quite a bit. They were very thorough with the mold report, showing exactly what needed to be done and how to remediate the mold in a particular area.After removing the mold they do a retest to make sure all of the mold has been remediated. Unfortunately more mold was found in other areas.We can say we learned more about mold than we were expecting BUT it was important to make sure that all of the mold was gone. We ended up finding mold in 2 of our bedrooms and in the master bathroom as well as the crawl space.Because of how thorough they were we were able to get everything done so that we got clearance and was able to get those areas put back together.My wife was the one that was getting sick and we didnt know why, now her health has improved, and it all goes back to the mold.I highly recommend them. In checking with other mold testing companies, theyre reasonably priced. We found that other companies charge more for the same services.Charles is very patient and takes the time to educate you on whats happening and what needs to be done and the mold reports are quite detailed showing the infected areas.IF we ever ran into this problem again, which we hope we dont, I would call them without hesitation.
Thank you so much for taking the time to write such a thoughtful and thorough review.
We understand how disruptive mold issues can be, so we're so happy to know that you can finally return to your normal routine. It's always a big win when the lab results come back clean and Clearance passes!
It was a pleasure serving you, especially since you had such an upbeat and positive spirit throughout the entire process. Thank you again for the kind words and for giving us the opportunity to assist you. ~ Charles

We had a water heater leak in our lower level and wanted a mold test before remediation began. Charles came out within a day of calling. We thought the prices were reasonable and very transparent (you almost order Ala carte with how many swabs/tests you want to do). Results took two days. Our leak had resulted in mold forming (visible and airborne) within 24-48 hours of the leak, which we had caught almost immediately. Charles walked us through all the test results and broke them down into language we could understand, hah! Honestly though, that last part is important, being able to understand exactly what the test results mean. Since we have mold, once remediation is completed, we will have Charles come out to do clearance testing in a few weeks. We highly recommend and are very happy with the service.
Andrew, thank you both again for allowing us to assist. It was a pleasure working with you and it always makes us happy whenever we can detect and confirm mold growth problems early on, especially when it may not be readily visible at first. Since you addressed the moisture issue right away, you are in the best position to quickly remediate the mold growth. Thanks again for the opportunity and looking forward to seeing a clean lab report soon! ~ Charles

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
Since each effort varies in scope, please contact Tanjun Mold Inspections to assess your unique needs.
A base inspection fee applies along with a per sample lab fee where applicable.
We will send an estimate for review along with the pre-inspection agreement.
What is your typical process for working with a new customer?
Prior to the visit, we typically try to gather key information about the nature of the request.
If air sampling is required, windows and doors should remain closed for at least 24 hours prior to the inspection appointment.
Once on site, we will consult with the property owner to focus on areas where there is suspected mold growth or where there has been water damage or moisture issues. If lab samples are recommended, we will review details with the customer.
Once all of the data is collected, we provide a report of our findings. If a mold growth problem is identified, a remediation protocol is outlined.
