The buildings and the hardware
The housing stock affects the hardware we see. Limerick has a mix of detached houses, newer subdivisions, and some multi-unit buildings, so doors range from solid wood and steel exterior doors to hollow-core interior doors. Older doors often keep original mortise or rim locks that need new cylinders or strike reinforcement; newer homes have bored cylindrical locks and deadbolts that are straightforward to replace. Apartments bring keyed-entry systems and sometimes mailbox locks. Commercial storefronts, where present, use heavier commercial-grade locks and exit hardware. Knowing the door construction tells us which fasteners and strike plates will hold up under everyday use.
