there is not a whole lot you can do to prevent them from wearing out (short of changing the anode rod).Other things relate to the difficulty of proper installation. Sliding glass doors for instance, many people that can read a level and drive a nail with a hammer can install a sliding glass door. However getting the door to latch properly takes a higher level of patience and/or skill.
If the wall plate is too low the latch will not engage at all and the door can be opened with the lock fully engaged. This is seen less often but is also not proper and a stick in the door should not be relied upon!
The wall plate could also be in the wrong position side-to-side. This is likely the cause of most of
Once the wall plate is in the right spot to allow you to close the door, then throw the bolt and have the bolt engage it is time to install the 3” or better “security screws.” This is another item that I see missing over and over. The long screws tie the whole door frame to the wood frame of the home. This is much better than relying on the vinyl frame and provides a more stable lock.
Hearing about contractors that state, “this is how the door is designed to lock,” is the worst and I must explain to my client’s that it is time to find a new contractor.
