For Door Dragging and Scraping the Floor When Opening, start with "Tighten the top hinge screws before anything else": Open the door halfway and lift the handle — if there's play at the top hinge, that's your problem. Take a screwdriver and tighten every screw on the top hinge, both on the jamb side and door side. A lot of dragging doors are just loose screws. Test the swing before you do anything that removes material. Stop DIY if the door frame itself is pulling away from the wall — this is a structural issue, not a hinge problem. This is listed as a easy recovery and usually takes about 15 minutes.

help1. Understand the Problem

Interior doors drag on the floor when hinge screws loosen from repeated use, letting the top hinge pull away from the jamb. Over time the door sags at the latch corner and the bottom edge catches carpet or hardwood. It's rarely a swollen door — almost always a hinge problem.

Best First Step

Tighten the top hinge screws before anything else

Open the door halfway and lift the handle — if there's play at the top hinge, that's your problem. Take a screwdriver and tighten every screw on the top hinge, both on the jamb side and door side. A lot of dragging doors are just loose screws. Test the swing before you do anything that removes material.

See what's happening and how to try the first recovery step.

Replace stripped screw holes with longer screwsIf the top hinge screws spin without tightening, the hole is stripped. Remove one screw, swap in a 3-inch wood screw that bites into the framing behind the jamb. Do one screw at a time so the door stays aligned. The longer screw pulls the jamb back tight.

Pack stripped holes with toothpicks and wood glueIf you don't have longer screws, pull the hinge screws out, squeeze wood glue into the hole, stuff it with wooden toothpicks or a golf tee, and snap them off flush. Let the glue set for 20 minutes, then drive the original screws back in. The toothpicks give the threads fresh wood to grab.

Shim behind the bottom hinge if the door still dragsIf tightening didn't fix it and the gap at the top lock-side is wider than the bottom, the hinge mortises may be too deep. Cut a thin strip of cardboard or a door shim, place it behind the bottom hinge leaf on the jamb side, and reinstall the screws. This tilts the bottom corner up slightly.

Bend the hinge knuckles with an adjustable wrenchA hack that works for mild sag: slide an adjustable wrench over one hinge knuckle, close the door until the pin binds, and gently lever the hinge back into alignment. Go slow — you're bending brass, not steel.

Sand or plane the bottom edge as a last resortIf the door is truly swollen or the floor is uneven and hinge fixes didn't work, take the door off the hinges (tap the pins out), run a belt sander or block plane along the bottom edge, and rehang. Remove the absolute minimum material.

Frequently Asked Questions

Why does my door only scrape the floor in summer?expand_more

Humidity swells wood. If it scrapes in summer and swings fine in winter, the door is absorbing moisture. A dehumidifier helps, but sanding the bottom edge 1/16 inch during dry season is the permanent fix.

Can I just cut the bottom of the door with a circular saw while it's still hung?expand_more

Bad idea. You can't get a clean cut with the door still on, and you'll chew up the jamb. Always pull the hinge pins and take the door down to trim it properly.

The top hinge screws are tight but the door still drags. What next?expand_more

Check if the top hinge pin is worn or bent. Remove the pin, roll it on a flat surface — if it wobbles, replace it. A worn hinge pin causes the same sag as loose screws.

How much gap should there be between door and floor?expand_more

Interior doors need about 1/2 to 3/4 inch clearance for carpet and airflow. Exterior doors can be tighter — 1/4 inch — but need a threshold seal underneath.
