"Representative arrived before the scheduled time (which was not a problem for us).  We requested lead paint testing of the kitchen area where some minor modifications were to be done.  Testing was a requirement from the contractor.
He offered to test other adjacent areas at no charge.  He was friendly, polite and the whole process took less than 30 minutes.
Lastly, the cost was considerably less than other vendors, including the one referred by the big box home improvement store.

"Ron was absolutely wonderful and immediately allayed any fears I had concerning the mold remediation. When I first called him, he spent a considerable amount of time explaining about mold and his protocol in examining a site. After explaining that he uses the EPA guidelines in his recommendations for remediation, I knew I had the right man for my needs. He completely examined the affected area, took lab samples and sent me his very detailed preliminary report containing the treatment recommendations and a separate report with the lab results. Because this was for a rental unit with two small children within the family of occupants, I knew I had to be thorough and careful in my treatment approach. Ron gave me complete confidence in moving forward with a treatment plan. He very generously offered to guide the workmen I had hired to do the job so that the treatment would be done properly. I not only took him up on his offer, but arranged to have final lab testing done after treatment to make sure there was nothing left to cause future problems. Ron is completely professional, very knowledgeable and most generous with his time and professional support. He will be my only go to man for mold analysis and treatment recommendations. Highly recommend! ***UPDATE*** 1/17/11 When work was finally commenced on the property Ron had done testing on 1/7/11, the contractor thought he found another potential mold area behind the wall where the water damage had originated. Anxiously and in a near panic, I contacted Ron on Sunday 1/16/11 for his guidance on how to approach the problem. Ron guided the workman on what to do by phone, and then about an hour later came out to take a lab sample which ultimately came back clean. No mold was found behind the wall, by the way. All this on a football playoff Sunday! Ron is so awesomely superior in his service that he blows away the competition. He not only saved me thousands over a bid I had received from a mold remediation company for the job, but gave superlative support through the entire process. Before you spend thousands on a suspected mold remediation project, give Ron a call first. You will get an HONEST evaluation of your problem that just may save you thousands without tearing apart your house, but if it turns out that this is necessary - and he'll give you the no bull assessment - you can rest assured that Ron will give you outstanding guidance through the process to a clean finish."

"Mike was extremely courteous and thorough with his testing. He explained how the testing device worked and the readings it produced."

"My remediation was challenging because I live a couple states away from the house I own. I had received a quote from another company saying that my whole bathroom needed to be torn out. When AM/PM inspected, they suspected that the damage was not that widespread. Sure enough, when they did the demo, the mold had not spread widely into the walls. I appreciated their honesty, even though it meant a smaller job. Maya came to the house to assess the damage, then remained my point of contact throughout the job. She was kind, knowledgable and professional. She even recommended a 3rd party testing company to come and certify their work. AND all of this happened over the Christmas holiday. I was very happy with the service overall. My bathroom looks great and I have a certificate of remediation for my tenants. Thankful for this team."

"We've used them for years. And the comments are they were very through, and clean."

"Mold was found behind the walls in our master bathroom during demolition for a remodel. We contacted 3 companies for mold remediation estimates. Circle Vision wasn't the cheapest, but their review of the site and estimate was the most thorough, and they made us confident that they would do their best to reduce the amount of additional repairs that would be required after remediation was over. Carlos was the lead for our project and he did a great job explaining every step of the work and was very easy to get ahold of for scheduling. Gus Jr. and Gus Sr. conducted the remediation at our house for 2 days. They arrived on time each day, protected the floor with paper, vaccumed and swept at the end of each day, and left the house cleaner than when they left. They were very professional and answered any questions we had. They left an air scrubber at the house for a few days to make sure all traces of mold were gone. They left the dining room wall covered with plastic so our toddler and cats wouldn't get in to the unfinished bathroom. When the inspector returned, he found everything was done to the letter and we passed inspection with no problems.
