The buildings and the hardware
The types of buildings and their doors affect what needs doing. A lot of houses here have older wood doors and frames that shift with settling and humidity, so you see misaligned strike plates, elongated screw holes, and mortise-style hardware that requires different tools than a modern bored lock. Apartment buildings bring more common-area hardware, master-key systems and mailbox clusters; storefronts use heavier commercial locks and sometimes exit devices or metal frames that take different bolts. That variety means we carry both residential cylinders and heavier commercial hardware and the parts to adapt them on site.
