Cesar was professional, a gentleman, friendly, courteous, educated and took his time to thoroughly go through each room in my house. When he was finished, he explained everything to me in detail. The most important part about Cesar was that he walked in integrity and honesty. Especially for those two main reasons, I will recommend him and Mold Inspection Sciences, Inc. to anyone that I hear needs a mold inspector.

Joseph did an absolutely incredible job! He was very professional, thorough, explained everything he was doing and after the lengthy inspection of our home inside and out top to bottom, he shared his findings and recommended samples with detail and answered all of my questions before proceeding to collect the samples. I’m very thankful for his experience and would definitely recommend him and the company!

I hired Mold Inspection Sciences to inspect a home I was in contract to purchase in Colorado. I had CIRS/MRI from previous toxic mold exposure.

Their inspection was thorough and identified hidden mold in the building envelope that would not have been otherwise identified. I can't thank them enough for saving me from purchasing and living in a moldy home.

Johnny was my inspector and was knowledgeable and professional.
