Gilad of Baltimore Door & Lock brought expertise with him in terms of carrying out the installation, he installed a single cylinder deadbolt and made sure that everything was done properly, the installation was tidy, quick, and carried out with great care, Gilad explained everything upfront and didn’t try to rush the process. The lock is very secure, and closing the door is now perfect. I am very satisfied with the service offered Baltimore Door & Lock and would not think twice about using their residential services in the future.
