I was contacted prior to their arrival. The technician was very polite and efficient. After he looked at the door he informed me of the cause and corrective actions he would need to take to fix the door. No work was done until we had talked about what was needed, this included other options. After the work was done he explained and showed me what was done and how to maintain it. I am very pleased with the work and recommend O'Brien to anyone that wants good, quality work.
