I have nothing but positive things to say about Steve and my experience. He is so knowledgeable and gave us a very thorough explanation of what he found during his inspection. I have never dealt with a mold problem before so I had a lot of questions. He was so gracious with his time and helped me understand what was going on. I really appreciate the wonderful advice he gave us. He have us so much information about how to keep our family safe and have it to us in writing so that it was easy to follow. Its clear that Steve really cares about his customers. I dont know what we would have done

The second company we hired they were just as incompetent as Guaranteed Home and Mold Inspection. Stay clear and call a professional company.

Above and beyond excellent report done on our apartment, allowing us to get out of a water damaged unit that wasn't properly repaired. There is still moisture and since moving in here I've been having all kinds of symptoms. A professional inspection with lab results was needed. Steve was very thorough in his report and recommendations. Its very well written. My apartment complex responded almost immediately with the option to terminate without penalty. Often times you have a battle on your hands but armed with a report like this, you're standing on solid ground.

I called to inquire about Steves mold inspection services, because of how my apartment company was fixing a mold issue was incorrect and hazardous. Based on the photos I sent of the shotty work that was in progress and halted by me he made a basic assessment off the visuals and was very helpful with advice on what I could do to help my situation. Not very many companies will offer advice or visual assessments. Not only do I feel that Steve was very professional but he went out of his way to help someone. I highly recommend him and his company. I dont think you should go anywhere else.

If you have any doubts, I highly recommend Steve for any inspections you may need. He is highly informative and presents his responses in a manner which is understandable and follows through w/ the best course of action for your situation. We suspected there was residual damage in a home we were renting due to the wife's failing health and landlords poor mold remediation and we were right. Now we are going after the homeowner for damages!
