"My apartment had multiple leaks and growing mold before I moved in. My landlord originally was not willing to go through a remediation process, so Celtic Mold Assessments was recommended from my father who works in construction and has experience with them. John has been a live saver during the whole process from start to finish. He answers any questions, gives recommendations, and has so much knowledge and expertise. He is diligent in ensuring the safety of his customers and works above and beyond. Not only has he been updating my family about everything going on in my apartment, he has gone out of his way to assist my landlord with the process to make sure it is safe. I would highly recommend contacting Celtic Mold Assessments for any mold issues, whether a home owner or tenant."
