What Goes Into a Professional Door Knob Lock Installation
Installing a door knob with lock and key sounds straightforward until you're staring at a door with non-standard boring, an older mortise lock cutout, or a frame that has shifted over decades of Staten Island winters. Our technicians assess the door thickness, backset measurement, cross-bore diameter, and latch compatibility before any hardware goes in. That pre-installation check is what separates a secure, long-lasting fit from a sloppy install that binds, rattles, or fails the first week.
We work with leading hardware brands — Schlage, Kwikset, and others — and we carry a broad inventory on every service vehicle so most installations are completed in a single visit. Whether you need a passage knob for an interior hallway, a keyed-entry knob lock for a side door, or a privacy knob for a bathroom, we size the hardware correctly, seat the latch squarely in the strike plate, and test the throw under real closing pressure before we leave. Every door knob lock installation we complete is done with a damage-free approach wherever the existing door and frame allow it.
