We were very impressed with the investigation. It was very much needed. There were things I was not aware of like the water running outside the building, trees growing in the gutters, etc. Thank you again.

If you are looking for a legitimate company, look no further! These guys are as professional as it gets and very thorough. We really appreciate everything you have done for us. Robert and Charles are fantastic! Can't say enough good things about them.

On a side note...do your research before you hire a company for environmental testing. The first company we contacted was clueless and tried selling us a mist that would soak through everything and kill mold. Red flags went off, especially since they could not find it. Robert and Charles came in and found it all (and Serv Pro). Unfortunately, we had a toxic mold found hidden behind my kids walls. The spores then got into our HVAC system and blew it everywhere. These guys created a plan to remediate it, and now we are all clear.

My family, especially my 3 children, suffered for years because of this mold. My son was hospitalized twice in the last year alone. Numerous surgeries between them. Now, they are all getting better! This stuff is no joke...so don't go cheap. They are worth every penny!!

I had the opportunity to work with Robert Crawley during 2018 as he assisted a young family I was representing in a significant residential mold remediation matter. My clients and I were very impressed with the personal hands-on professional attention he rendered all of us in this most trying set of circumstances. He made himself available for personal inspections of the premises and deposition purposes. His testimony was objective, believable and persuasive to all attorneys and parties involved. I would highly recommend Mr Crawley for your consideration in these such matters.

I just wanted to let you know we are so VERY PLEASED with your company!!! Charles was very professional took his time, and explained everything in detail! But, what pleased us more than anything, before he left he asked to pray over our daughter who has been very sick. The fact he took the time to do that meant a lot to us! I wasn't sure where to leave a review, but I did find you all on Google and left one there. We will definitely be referring your company to everyone we know! Thank you so much for your help!!!!
Honesty, Integrity and Professionalism. I have worked with Robert Crawley on a few mold projects I highly recommend his company.
