What Our Clients Say

"I contacted Fast Mold Testing around 6pm to request an onsite mold inspection as soon as possible. It was late in the day so I didn’t expect to hear from anyone until the next day. To my surprise, Josh from Fast Mold Testing contacted me right away! I had never done a mold inspection before, and Josh took the time to explain the entire process. He walked me through the different testing options and the pricing for each one. I asked many questions and he answered every single one with patience. Within an hour he arranged for an inspector, Ivan, to come out the very next day. Ivan even messaged me that same evening to confirm the appointment. On the day of the inspection, Ivan arrived on time and put on his own shoe covers the moment he stepped into my unit. Many contractors walk in with their outside shoes without asking, so I appreciated his professionalism and care right away. He used a moisture meter and a thermal imaging tool to check for water leakage inside the walls. While testing, he explained each step and described what he was looking for. He also brought equipment to collect indoor and outdoor air samples. His inspection was very thorough. He checked under the sink, the bathrooms, and every corner where moisture or mold might appear. He also examined outdoor areas to help identify a possible source of leakage. While waiting for the air samples to finish, Ivan walked me through his findings and explained how to spot early signs of water issues in the future. He shared practical tips on reducing indoor moisture and preventing mold growth. His advice on sanitizing mold contaminated clothing, purses, and shoes before moving them to another place was especially helpful. Ivan is clearly very knowledgeable in mold inspection and remediation. He is professional, detailed, and friendly. I truly appreciate the time he spent educating me. Josh originally told me that the lab results would take about three business days. Since the inspection took place right before Thanksgiving, I expected to wait at least a week. To my surprise, the full and detailed mold report arrived on Sunday. Josh even called me on Monday to confirm that I received it. Because I wanted to make sure I understood the report correctly, he is arranging a call for someone to review it with me. The entire process was transparent and straightforward. It is clear that Fast Mold Testing takes great care of their customers. I would recommend them without hesitation to anyone who needs mold inspection."
