"John M. was courteous, timely, and professional in his inspection. He was upfront about the issues -- whether they are serious or minor, rare or common, and whether more specialized input is required. His written report was very well done and will serve as a great home guide for us in the future after we move in. Thank you!"

"Very Professional followed all federal, city, and state guidelines to conduct a mold assessment. Provided a comprehensive report that wad thorough and straightforward making it easily understandable and made themselves available due to my immediate concerns and went above and beyond my expectations. Very upfront and doesnâ t sugar coat anything by telling you things are fine or arenâ t fine but instead details the specifics and explains what exactly he is doing when heâ s doing it to help better inform you of how to not only prevent the growth of visible mold but how to best limit the exposure to it and most importantly he wore proper safety equipment gloves mask and shoe covers and respectively followed all COVID-19 guidelines set in place. Mike knows what heâ s doing, heâ s got the credentials and the experience and knowledge and he applied everything in an unbiased mold assessment of my apartment for a reasonable price. I would highly recommend him and would suggest reading his reviews before considering others because he is clearly a well respected and reputable resource in the areas he specializes in and his work proofs that! Thanks Mike Brandon"
