Use Bio Clean if you need mold remediation done right!!!These past few months my son has been sick with a cough that seemed to be turning into asthma. I wasn't sure what was the cause as it started to happen pretty soon after moving into our new house. I had Bio Clean come out and test my house to see what was in the air. They did an inspection of my home and found that we had a water leak under our sink that resulted in mold. The test that they took came back high for certain molds that could be causing my son's asthma to get worse. The unfortunate part for me was that the mold levels in the rest of our bedrooms were also in an unsafe mold.I had John and his team come out right away, and they were able to clean up all the mold throughout our house. He also suggested a mold fumigation process that we went with as well.After the remediation was complete, we moved back in and my son has been feeling better ever since. His asthma and cough have subsided, and we are extremely grateful for John and his team.I HIGHLY recommend using John and Bio Clean to anyone who is suffering from mold.

We are so thankful for the team at BioClean. The entire family (including the dogs) regained their health after the friendly and respectful team did their inspection and remediation work. We are truly grateful!

John is the best!! Super helpful and did an amazing job. He also helped us on one off questions we had not related to the remediation work he did for us - just other parts of our house. Was really nice and really helpful. I would definitely work with John again if ever needed.

John Watts was recommended as the BEST NORMI CERTIFIED MOLD INVESTIGATOR, TESTER AND REMEDIATION SPECIALIST to us by a specialist in San Diego.We were deathly sick for several months, choking one our own mucus, falling over 20 times and had no idea what was wrong wiht us. We had just bought a new house and it was infested with mold in the attic, in the crawl space and on all inside exterior walls and insulation. Although overbooked, he tried to his best to get us in as quickly as possible . HIs testing was impeccable having shared it with the Regional teacher of the NORMI certification , he was really pleased with his thoroughness. The tests showed three different molds the black of course being the worse. He could even specify which areas were the worst and why, but the whole house had to be processed and there was extensive mold down to the studs and insulation all over the house. He worked so many hours non stop with his crew , because he knew how sick we were and that we were homeless. He did it all in two weeks. He came back months later as the whole house had to be re-insulated, new sheet rock and an extensive drainage system outside the house and under the crawl space. We were homeless for 5 months all together. He was patient ,kind and an d a real expert in his field and often gave advice how to keep the mold away and recently helped us figure out how to determine if we were using enough dehumidifiers keep the house stay safe.His staff was wonderful and respectful and hopefully we never to do this again. Certainly. he waited along time until after the construction was finished to do the final extensive testing and it came back so clear. We have been living back in our house 4-5 months and have had no medical problems and he has been best expert and a friend. He is trustworthy, honest and had enormous integrity.

5 stars — Bio Clean (John Watt)John from Bio Clean was fantastic—super conscientious and genuinely kind. He and his son make a great team: professional, communicative, and thorough from start to finish. I interviewed another company that felt a bit pushy and excessive, but John’s approach was transparent and calm, and his price was more reasonable. He even found mold in an unexpected area, explained the plan clearly, remediated it properly, and finished a full day earlier than I expected. The results exceeded my expectations. I highly recommend Bio Clean and John Watt—reliable, fair, and excellent at what they do.

I highly recommend John Watt, Good Housekeeping Inc., for residential mold investigation, analysis, and remediation. He has access to breath of test modalities, depending on the level of investigation. In my situation we were able to correlate a household issue with a health issue. John is a very strong problem solver who traces the test results to the assignable causes. His remediation methods are natural and safe. In addition, I found his customer service, including scheduling, exceptional.
