"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

"It went great. Alex brought the test kit to my house on a Saturday morning (!) as planned at the time he said he would arrive and placed it in a good position. He gave me clear instructions for the test. They were very easy to follow. He emailed information about the test beforehand and also gave me status on the test results. He also gave me the test report as soon as they were available. I did not have to follow up at all. I am very pleased with the service provided. I would definitely use him again and recommend him to anyone."
