Slab vs Prehung Interior Doors
A slab installation depends heavily on the existing frame. Hinge locations, jamb alignment and latch position all have to work with the new door. A prehung unit provides a coordinated jamb but usually affects casing and the wall-to-frame transition.
Interior doors sit within the broader exterior home improvements category only because of the accepted site architecture; the work itself is an interior opening service. Exterior entrances belong to entry door installation.
Jamb, Opening and Wall Thickness
Measure the opening, but also inspect the jamb for damage, twist or prior modifications. Wall thickness matters for a prehung frame, and finished flooring can change the usable height beneath the door.
If the opening needs reframing rather than simply receiving a new unit, mention that condition so the scope is not treated as a standard door swap.
Swing, Clearance and Room Function
Door swing affects furniture, switches and walking paths. Bathrooms and bedrooms create privacy needs; closets may need different clearance strategies. A new door should open without colliding with fixtures or blocking a narrow hall.
Decorative glazing may be appropriate for some interior applications; the decorative door glass / architectural glass page handles that material-specific discussion.
Hardware and Privacy Needs
Passage, privacy and keyed hardware serve different rooms. Existing bore locations can limit hardware choices on a slab replacement. If a door sticks or latches poorly but the unit itself is still suitable, door repair may solve the problem without full replacement.
Trim, Paint and Flooring Transitions
Replacing a jamb can disturb casing and wall paint. Floor height and thresholds can affect the door bottom. Plan touch-up or trim work according to the actual opening rather than assuming a new door ends with hanging the slab.
Repair vs Replacement
Loose hinges, minor alignment problems and worn hardware can sometimes be repaired. Damaged slabs, failed jambs or major fit problems may support replacement. Share photos of the hinge side, latch side and top/bottom gaps to help describe the condition.
