The technician arrived on time and gave me a quote on the work that I wanted doing. He then quickly installed the 3 dead bolts and explain that the double sided lock was a special type of lock and he would need to go to his supplier for that lock as it was not standard. He was back quickly with the appropriate lock which he replaced and then worked on aligning the door and installing the interior dead bolt. He worked quickly and cleaned up after him self. He then demonstrated all the locks he had replaced/installed. The work was completed in a good time frame and I was happy with the work that they did. I would definitely use this company again.
