Rarely are hinges the problem. Everyone pays attention to the door and the hinges, what most people don’t realize is the door frame is more often the problem. For example. Many people decide to install high security door locks and hardware on their homes, and any locksmith will happily install them for you at a hefty cost. But, think about this a bit before you decide to do the same thing. The majority of doors are hollow core or fibreglass with thin wooden frames. They look great, but one solid kick at the lock and the cheap frame shatters like cardboard. So, ask yourself, does it make sense to install a $600 high security lock and hinges on a $100 on door?
Most if not all door frames are 1/2" to 5/8" thick, and not made of hardwood, usually spruce, pine or cedar and only held in place by a few screws or nails. So any strong locks or hinges are only as strong as the door/frame they are attached to. If you want hinges that don’t sag, and locks that are high security, start with a solid 3/4 to 1 inch hardwood frame, securely bolted/lagged to the sub frame then install a solid hardwood door. Your locks and hinges will outlast the house and defeat most would be burglars!
