If a homeowner wishes to make the doors more secure or a lock is broken we offer lock changing services. Each lock is unique, for example, lock sizes and security levels can differ. If a client wishes to change a lock, we usually offer to change the existing lock to an identical new lock. The security level of a door can be increased by installing an additional lock, which is usually called a "spider" lock. We advise you to trust our experts with choosing a lock since they are very experienced in lock constructions and will know what lock will fit your doors best. We also offer door restoration services. More information is available here. Manufacturer's warrant is provided for all locks.
