Flooring alters clearance
New carpet, tile, or floating flooring can reduce bottom clearance or change thresholds. Before cutting a door, verify the finished floor and expected transition.
Use the reveals as a diagnostic map
The reveal is the gap between the slab and jamb. A tight upper latch corner with a wider gap below can suggest hinge-side sag. A consistent tight edge may reflect paint buildup or swelling. A latch that misses vertically can follow hinge movement, while a latch that does not reach the strike can relate to depth, weather, or frame position. Looking at all gaps is more useful than sanding the first rub mark.
Check support before removing wood
Open the door partway and observe whether the hinge leaves move against the jamb or slab. Loose fasteners, worn holes, bent hinges, paint trapped behind a leaf, or an unsupported jamb can change the swing. Restoring secure hinge support can move the latch side substantially. Planing first may create a permanent oversized gap after the hinge problem is corrected.
Seasonal swelling needs patience
Wood responds to indoor humidity, and older solid-wood doors may change more noticeably than stable composite products. Document when sticking begins and whether it releases during a drier season. The right repair may involve humidity control, sealing an exposed edge, minor adjustment, or carefully limited trimming after the movement range is understood.
Several symptoms can point beyond the door
One sticking door is often an opening-level problem. Several doors changing together, new wall cracks, sloped floors, separated trim, or rapid movement deserve a broader building assessment. The door is a useful indicator, but it does not identify the structural cause by itself.
Start with the least destructive explanation
The repair sequence should preserve material until alignment and seasonal behavior are understood.
| Condition | Likely next step | Reason |
|---|---|---|
| Visible hinge movement or loose screws | Restore hinge support first | A small hinge shift changes the opposite corner significantly. |
| Fresh paint buildup at a stable contact point | Careful finish correction may work | The slab geometry may still be correct. |
| Sticking only during humid periods | Document and control moisture before trimming | Removing wood at maximum swelling can leave a winter gap. |
| New floor reduced bottom clearance | Evaluate safe, even bottom modification | Flooring changed the available opening height. |
| Several nearby movement symptoms | Seek broader evaluation | The frame may be responding to building movement. |
