What's inside
Two ways to hang it
Part A walks the common pre-hung install; Part B is the pro track — fitting a bare slab into an existing jamb.
Step-by-step with diagrams
Clear illustrations for door handing, the reveal, shim placement, hinge mortises, and the lock bore.
Tools & materials checklist
Exactly what to buy for the job — matched to the tool kit you can add right below.
Pro techniques
The long top-hinge screw, back-beveling the latch edge, and setting an even, lasting reveal.
Troubleshooting table
Fix a door that won't latch, binds on the strike side, or drifts open on its own.
Final checklist
Everything to verify before you walk away, so the door opens with a fingertip and clicks shut.
Your first door, done right
Follow Part A for a new closet, bedroom, or bathroom door — no special skills, just the steps in order.
The money skill on remodels
Master Part B for old houses where nothing is square — mortising hinges and boring a lockset by hand.
