How Do You Fix a Sticking Wood Door That Rubs the Frame?

You fix a sticking wood door by first driving a 3-inch (7.6 cm) wood screw into the top hinge to pull the heavy door back into alignment, rather than immediately sanding the wood. Wood doors inevitably sag over time because their solid weight pulls the short, factory-installed top hinge screws loose from the soft pine framing studs. If tightening the hinges does not restore the necessary 1/8-inch (3 mm) gap between the door and the jamb, you must shim the bottom hinge to pivot the door upward. Only as a last resort should you remove the door from its pins to plane the rubbing edge. By addressing the hinges first, you fix the root cause of the sag instead of permanently altering the dimensions of the door.

• Diagnose the exact point of friction using a piece of carbon paper or a dollar bill before making any adjustments.
• Replace standard 3/4-inch hinge screws with 3-inch screws to securely anchor the door frame to the wall studs.
• Use 1/16-inch cardboard or plastic shims behind hinge plates to tilt a stubborn door back into alignment.
• Plane wood only as a last resort, and always seal the newly exposed wood with exterior-grade primer to block moisture.

Why Do Interior Wood Doors Start Sticking Over Time?

Wood doors stick against their frames for two distinct reasons: gravity and humidity. Over years of swinging, the sheer weight of a solid core or heavy wood panel door places immense stress on the top hinge. The factory-provided screws are typically only 3/4-inch (1.9 cm) long, meaning they only bite into the thin door jamb, not the structural framing studs behind it. Over time, these short screws tear out slightly, allowing the top of the door to sag downward and rub against the upper latch-side corner of the frame.

Humidity acts as the second culprit. When indoor relative humidity climbs above 55 percent during the summer, unsealed wood absorbs airborne moisture and swells across its grain. A door that swings perfectly in dry January air will often expand by as much as 1/8 inch (3 mm) by July, entirely closing the gap required for clearance. If a door only sticks during the summer months, humidity is the primary cause, whereas a door that sticks year-round is suffering from a sagging hinge.

• Sagging: Caused by short screws pulling out of the top hinge under the door's weight.
• Swelling: Caused by indoor humidity exceeding 55 percent, forcing wood fibers to expand.
• Settling: Caused by the house foundation shifting, knocking the door frame out of square.

How Do You Pinpoint Exactly Where the Door Is Rubbing?

Before you touch a screwdriver, you must locate the exact friction point. Do not rely on your eyes alone. Close the door slowly and look for areas where the paint is scuffed, transferred, or chipped along the edge. The standard clearance between a door and its jamb should be a uniform 1/8 inch (3 mm) on the top and both sides.

To find the invisible pinch points, use the dollar bill trick. Open the door, place a crisp dollar bill between the door and the jamb, and close the door. Slowly pull the bill downward along the gap. Wherever the bill gets stuck or tears, mark the jamb with a pencil. You can also use a sheet of carbon paper taped to the jamb; closing the door against it will leave a dark smudge on the door edge exactly where it binds.

Why Should You Always Start by Driving a Three-Inch Screw?

This is the most critical judgment call where professionals diverge from beginners. A beginner dealing with a sticking door will almost always grab a sander or a hand plane and immediately start shaving down the wood. A pro leaves the wood alone and reaches for an impact driver. Sanding a sagging door permanently ruins its geometry; if you ever fix the hinges later, you will be left with a massive, drafty gap.

To fix a top-latch rub, remove the middle screw on the jamb side of the top hinge. Drive a 3-inch (7.6 cm) #9 wood screw straight through that hole, penetrating through the jamb and deep into the structural 2x4 framing stud behind the wall. As the screw bites into the stud, watch the door gap. The long screw will physically pull the sagging jamb and the hinge tightly against the framing, lifting the door away from the latch side. Drive the screw slowly so you do not bow the jamb too far inward.

How Do You Shim a Hinge to Fix a Bottom Rub?

If the door is rubbing at the bottom latch side or dragging on the floor, tightening the top hinge will not help. Instead, you need to push the bottom of the door outward. You accomplish this by placing a shim behind the bottom hinge plate.

Loosen the screws on the jamb side of the bottom hinge just enough to slip a thin piece of material behind the metal leaf. You can purchase specialized plastic hinge shims for about $5 in 2026, but a piece of thick cardboard or a playing card works just as well. A single 1/16-inch (1.5 mm) shim placed behind the bottom hinge will pivot the door slightly, raising the bottom latch corner by as much as 3/16 inch (4.7 mm). Tighten the screws back down and test the swing.

When Is It Finally Time to Plane or Sand the Wood?

If you have tightened the top hinge, shimmed the bottom hinge, and verified the door frame itself is completely square, but the door still binds, the wood has permanently swollen out of dimension. At this point, you must remove material. For minor sticking affecting less than 1/16 inch (1.5 mm) of clearance, you can leave the door on its hinges and use a coarse 60-grit sanding block wrapped around a scrap piece of wood to shave down the binding spot.

For anything thicker than a heavy coat of paint, you need to remove the door from its hinge pins and use a hand planer. A basic block plane costs between $45 and $85 in 2026 and is far more precise than a belt sander. Place the door on its side, secure it in a vise or have a helper hold it, and prepare to shave down the latch-side edge.

How Do You Plane the Door Edge Without Splintering the Wood?

A common failure mode for eager homeowners is pushing a hand plane all the way off the end of the door, which violently splinters the end grain on the top or bottom rail. To avoid tearing out chunks of expensive wood, never plane from the center of the door off the edge. Instead, start at the outside corners and push the plane inward toward the center of the door. This ensures the blade is always supported by the wood fibers.

When planing the latch side, add a slight 2-degree to 3-degree bevel angling toward the inside of the room. A perfectly flat edge on a thick door will actually strike the jamb as it swings in its arc. Beveling the edge slightly ensures the leading corner clears the frame smoothly. Take off razor-thin shavings, rehang the door to check the fit, and repeat until you achieve the necessary 1/8-inch (3 mm) gap.

Why Must You Seal the Door Immediately After Planing?

Once you have shaved away the binding section, you have exposed raw, unsealed wood to the air. If you rehang the door and leave the edge unfinished, that exposed wood acts like a sponge, absorbing atmospheric humidity. Within a few weeks of humid summer weather, the door will swell and start sticking all over again.

Wipe the newly planed edge with a tack cloth to remove dust. Apply a high-quality, exterior-grade wood primer, even if it is an interior door. Exterior primers contain superior moisture-blocking resins. Allow the primer to dry for two hours, lightly sand it with 220-grit paper, and finish with a coat of enamel paint that matches the rest of the door. Do not rehang the door until the paint is completely cured to a hard finish, otherwise, it will stick to the jamb's weatherstripping.
