Ken was great from start to finish. He took the time to talk with me before the inspection and let me know what to expect. Then, he set up an exact appointment (no four-hour window!) and worked with my schedule so I could avoid taking off too much time from work. He was on time to our place and was professional and polite, explaining more about his process and thoroughly checking out the problem. Throughout, he was excellent in his kindness, understanding, and communication. We agreed to two indoor air samples, in addition to the outside control sample. (He even talked us out of another sample as unnecessary!) Best of all, he was very calm and reassuring with my girlfriend, who was highly upset due to her asthma being seriously aggravated by the problem. As he promised, the lab results came back the next day (bad problem), and he had his full report to us the following day. It included an excellent, comprehensive protocol for selecting and hiring a remediation service. Having been through a mold situation three times in three separate places now, I can tell you firsthand how absolutely important it is to get an independent inspector/tester like Unbiased Mold Inspection, which does not do any remediation or anything else. A LOT of companies do it all, which can make their intentions suspect. With Ken and his company, you know you're getting an objective opinion from someone who's not trying to sell you more services.

Michael Davis and his crew were outstanding. 10/10 and I highly recommend his services. My boyfriend and I have been sick for months and could not figure out why. When we noticed the black spots in our ceiling, we realized that it could be environmental causes. I got on thumbtack and found Mold Control Services and talked to the owner Michael. Before I even thoroughly started to explain our symptoms, he knew exactly what was wrong. He came the next day to do a free inspection. I questioned him about air quality tests and what not but he told us that there's no point in wasting our money to do one when he knows the mold is already there. When I spoke with some other local companies, they were charging about 300-400$ just to do some tests. With Michael, he came to my house to inspect the mold for free and told us what was wrong right away. He is so knowledgeable in his field. He told us exactly what type of mold he thought it was and when he cut open the dry wall, it was exactly what he said it was. He is very thorough in his work. He made sure that the air quality in my home was back to normal as well as removing the mold that was on my bathroom ceiling. He is fair on price and he makes sure that his customers are looked out for. I know that these types of services are confusing sometimes and every company does it differently but Michael does it right. If you have mold or suspect you have mold, you need to call Mold Control Services. Michael will tell you the truth, everything you need to know, and charge you a very fair price to get it removed. I highly recommend him.

We contacted AdvantaClean of Frederick when we realized that we had a water and mold problem in a closet in our basement. AdvantaClean assessed the situation the next day and worked the better part of the day to clear and remediate the problem. They found an additional space with water and mold problem that we didn't know we had. They checked back in with us to test air quality once or twice. They removed contents from the affected spaces, which was really going above and beyond of what I would expect. I would highly recommend them to others. Top notch service and very knowledgeable of water and mold remediation.

Tim was very informative and knowledgeable about air quality issues. The tests he performed confirmed our suspensions that we had an air quality issue. It would have been great if the tests came back negative. However, we have a plan to get the problem solved.

I was concerned with the strange subtance I noticed in my basement. A friend of mine referred me to RAE Enviornmental Services. From the moment I spoke with the consultant over the phone I felt at ease. They were friendly and courteous and were able to accomodate my schedule immediately. The inpector was committed to providing the most thorough and comprehensive Mold inspection and testing available. He used state-of-the-art assessment procedures and equipment to completely evaluate the air quality in my home and identify the source of moisture and water intrusion that may have been causing mold growth. I felt their services were detailed, efficient, accurate and completed in a timely and professional manner. I was also provided with a full report and laboratory findings. Thanks RAE
