Doors that stick, sag, or fail to close completely are one of the most common sources of household frustration. Whether you are dealing with humidity-induced swelling or a frame that has settled over time, the solution is often straightforward. Learning how to adjust interior doors allows you to eliminate annoying noises, improve security, and extend the life of your hardware without the need for a replacement.
Diagnosing the Problem
Before turning a single screw, you must identify where the resistance is coming from. A proper diagnosis saves time and prevents unnecessary adjustments that could worsen the issue. Examine the gap between the door and the frame, looking for inconsistencies along the top, sides, and bottom.
Visual Inspection
Stand back and observe the doorway from a distance. Ideally, the gaps on the sides and top should be roughly equal. If one side is tight while the other is wide, the door is likely misaligned vertically or horizontally. Check for weatherstripping or old paint buildup where the door meets the frame, as these are frequent culprits for binding.
Tools Required for Adjustment You do not need a full workshop to complete this task. Most adjustments can be performed with a basic set of tools found in any home. Having the right equipment on hand ensures precision and prevents damage to the door or finish.

The hinges are the primary mechanism for vertical and horizontal alignment. By tightening or loosening the screws, you can shift the door slightly within the frame. This method is often the safest approach, as it does not require removing material.
Screw Adjustment
Begin by tightening the screws on the top hinge. If the door is sagging, this will lift the end slightly. If the door swings open too easily, you may need to loosen the hinge screws slightly to allow for repositioning, then tighten them once the alignment is correct. Use your level to confirm the door is plumb before moving to the next hinge.
Dealing with Door Sweell
High humidity can cause wooden doors to expand, making them difficult to open. When the wood swells, the door scrapes against the frame, usually at the top or the lock edge. In these cases, adjustment alone is insufficient; you must remove material.
