Ahmed TaftiGoogleTo start, I’m a researcher and I’m very knowledgeable in construction industry. I made the connection that my health was being affected by an ongoing water intrusion/mold issues hidden behind the walls. I have reason to believe the remediation company contaminated the rest of my home by not using negative air pressure and decontamination rooms. The main reason I picked Guaranteed was because of Demi’s patience and abilities to answer my questions in a way that didn’t leave me guessing if I’m picking the right company. Then I meet Joe when he came to do the inspection and his knowledge solidified my confidence that this was our guy. In an industry of predators, Joe made me feel like he had my back. We started out with Mold tests, then did an ERMI on the second round. He also seems to do everything by the books in case you need documentation for legal reasons
Jessica RichardsGoogleWe requested a full home inspection, and Demi was responsive and very helpful with answering questions and being flexible about our requirements. Joe came out and took off his boots at the doorway of his own accord. He listened to our concerns and kept us updated on how they reflected in his findings as he went through his inspection. He was upfront with the issues he could find on visual inspection, and his assessment of their cause. He also gave a clear timeline for when we could expect the results of the tests he did. Very reliable resource when you have to pick someone to give you bad news, lol.
JudyGoogleI had an excellent experience working with Joseph Gutierrez from Guaranteed Property Mold Company. From the very beginning, Joseph was professional, knowledgeable, and responsive. He took the time to explain the inspection and testing process thoroughly, answered all of my questions, and made sure I understood the findings and recommendations. What stood out most was his professionalism and attention to detail. He was punctual, courteous, and treated my family and home with respect throughout the process. Joseph’s communication was clear and consistent, and he demonstrated genuine concern for ensuring that the mold issues were properly evaluated and addressed. Dealing with potential mold concerns can be stressful, but Joseph made the process much easier by being transparent, reliable, and informative every step of the way. I highly recommend Joseph Gutierrez and Guaranteed Property Mold Company to anyone in need of mold inspection or remediation services. Thank you for your outstanding service!
Certified inspection & testing, one accountable team
The independent, certified inspection the volume shops can't offer
Most of the profiles you see near you lead on speed and a low price, and many are the company that also profits from the remediation. We are different on purpose. We inspect and test only, so our findings are never shaped by a cleanup we are trying to sell. Owner Joseph Gutierrez runs a certified, credentialed practice built for the cases that actually matter: real estate transactions, insurance claims, attorney and physician referrals, and independent post-remediation clearance.
