After we found potential asbestos tile during our family room renovation we contacted Geller Environmental. Spoke with Jack Geller who was very helpful, friendly and knowledgeable. Inevitably we had Geller Environ. do testing on our tiles, as well as on the plaster in our walls (which could also have asbestos - luckily, ours did not). The tests were done by Pat and Paul - who came to our house to take samples. During their visit to our house, they spent a great deal of time walking around the house to check for other potential locations of asbestos, and were accommodating in terms of answering all our questions. Likewise, they were especially great about getting back to us as soon as the tests results were available (knowing that we were biting our nails waiting to hear), and spent time explaining the results in laymens terms. We eventually used a remediation firm to remediate the asbestos tile (Geller Environ doesn't do the actual remediation) and because we enjoyed working with Jack and his crew so much, we hired them to do the air quality tests after remediation (i.e., to give the all clear). Once again, they were responsive to our needs, and very friendly. Overall, they were a pleasure to work with and would recommend them to anyone.
