Most people focus on upgrading their locks and ignore upgrading the door, but the door is usually the weaker component of the two. A strong lock on a hollow or worn out door frame still breaks with enough pressure, so this page is actually more about the door itself and not what closes the door.
Door materials
When considering material quality and security, steel doors stand at the forefront. Despite being easily damaged and not flexible, they are more secure than wooden doors. Composite doors are a viable middle ground because they contain a steel or wooden core and a wooden frame. This door type also allows a variety of frame styles to protect against theft while remaining aesthetically pleasing. Reinforced wood is a better option for older homes or other historic properties because steel doors detract from old home aesthetics. [internal link: door types]
Installation vs retrofit
While installing a new door allows you to properly fix the frame, retrofitting a security door relies on an existing frame creating a dilemma. Factory direct installations are more cost efficient and timely for door installation, but the overall strength of the security door relies on the frame it is retrofitted into, so it’s best to have the frame inspected prior to installation.

What actual breaks a break-in
Since most break-ins are done with the intent of breaking into many houses, the majority of burglars will not even attempt to damage a door and will move onto the next house in less than a minute if the door is not easily broken into. For this reason, security hinges, a strong frame, and multi-point locks are essential to protecting a home from theft even with the best door material.
Anti-snap cylinders and solid frames coupled with three-point locking mechanisms do more than any one expensive component.
There isn’t one door that works for all houses – it’s about striking a balance between security and the cost and appearance of the door.
