About Us

Joe and his team are amazing. They are extremely knowledgeable and caring in walking you through the steps. The inspection is thorough and professional, and you feel like they genuinely care abouthelping their customers.

We had to get tested in our commerical property! They came recommended and we are glad we called them! They were knowledgeable, honest, and thorough. We are so grateful they helped us make sure our kids building was safe and catch the wrong work done to take away our mold. Thank you so much ! Pasadena Foursqaure Church

Our family recently underwent a mold remediation process, which was quite unpleasant. It left us feeling sick and anxious about the possibility of going through it again, especially if we hired a company that didn’t take the time to do the job properly. We realized that air samples alone are not enough to ensure safety! We want to thank Joe for being thorough with his testing, as it provided our family with true peace of mind. We will definitely be using his services again in the near future for more testing and clearance. Thank you!

I recently used GPMI to inspect my home for mold after noticing a musty smell in our Newport North/ Irvine Company home. Joseph and his team were incredibly professional and thorough. As we feared and suspected, abnormal and high levels of MOLS SPORES for the following organisms throughout our Irvine Company home: Aspergillus Penicillium, Chaetomium and Stachybotrys.

They provided a detailed report with their findings, which we relayed to our Attorneys. Without this report and PROOF this property made us ill, the Irvine Company would continue to gaslight and say there "were zero issues with the unit." I would highly recommend them to anyone concerned with potential mold in their home.

GPMI is absolutely wonderful! They are one of the many reasons I am still alive today. After years of chasing my tail, wondering what was causing all sorts of health issues, my naturopath told me to consider environmental factors within the place I was renting. Western medicine was of no help, so I was at my wit's end. I started doing the research and was blessed to find Joe Hernandez and his company. He listened intently to my health issues and concerns. He was so great at being a straight shooter and offering advise on how to go about this. After he conducted the inspection, he provided me with an in-depth report, which provided me with the information I needed to make empowered decisions. I will forever be indebted to him and his team for the wonderful care and service.

We called Guaranteed Property Inspection after an extensive mold remediation in the home we are renting and subsequent inspections that passed but didn't seem thorough since some of us were still suffering from health issues. GPMI came highly recommended and we were very impressed with their service and communication. The owner, Joseph, recommended a plan for inspection, and Danny showed up right on time and did a very thorough inspection of the interior and exterior of our home. He explained everything he was doing along the way and was very gracious in answering all of our questions. He ended up finding some more mold throughout the home and took all the required samples to ensure a thorough report with recommendations and the safety of our family in mind. After going through a couple other inspection companies with shoddy results, we can't recommend GPMI any more. Hire them if you're concerned about mold in your home, whether you are a renter or a home owner. Dean walked an elegant line between being straight up and not BS'ing us about things that are legitimately concerning, but also didn't unnecessarily alarm us which I really appreciated after all we've been through. 5 stars!
