ll I wish there were more people like Doug in the Tampa area! Doug answered the phone promptly and arrived within his time estimate window. He was very polite and forthright throughout the install. He installed a Samsung Electronic lock for our house, which is much more complicated than a standard mechanical lock install. My door lock mounts were cored by the developer, and were substandard and not aligned correctly, which required Doug to re-core and re-drill their mistakes. Additionally, the electronic lock is very touchy about proper alignment and will not throw the deadbolt fully out if it is under pressure or has resistance. This was very frustrating and required Doug to assemble and disassemble the lock multiple times to troubleshoot the issue. However, Doug has an enormous amount of patience and eventually found the problem with alignment. Originally, Doug had quoted a half an hour for install, however, due to the door deficiencies, Doug ended up putting in 2 hours of work. As this was not his fault that the door was not prepared correctly, I was willing to pay him for the full 2 hours, however, he only charged me for an hour of work! Most of all, the lock works flawlessly!
