Why a Door Might Rub the Floor and How to Fix It
Are readers tired of a door that slams shut or drags along the floor? There are several reasons a door might start rubbing the floor, and understanding the cause leads to a longer-lasting fix.
- House layout. Over time, homes settle as soil and foundations shift, which can tilt door frames slightly and cause doors to rub the floor when opened or closed. This isn’t a mystery you solve with a single quick tweak. It often means stepping back to assess how the space sits in relation to gravity, traffic patterns, and even the placement of heavy furniture that might settle into place over the years.
- Climate changes. Wood reacts to humidity and temperature. In humid or hot environments, doors can swell and rub the floor, while cooler, drier periods may cause them to shrink. The result is a door fighting its own frame, a reminder that natural materials respond to the world around them. Regular seasonal checks help catch these shifts early before a stubborn scrape becomes a daily nuisance.
- Hinge wear. With frequent use, hinges can loosen or wear down, causing the door to sag and scrape the floor. This sagging creates a misalignment between the door and the strike plate or frame, producing new friction points and a perceptible drag along the threshold.
- Incorrect installation. A door or frame installed without precision can lead to closing issues and rubbing at the floor edge. Even small deviations in plumb or level can accumulate into noticeable rubbing and mischief at the bottom edge of the door.
- Door wear. On older doors, warping or other distortions can create contact with the floor as years pass. Hidden stresses from use, temperature, and humidity can exaggerate the problem, especially on hollow-core or lighter doors that bend more readily under load or draft.
These examples show common causes, but many other factors could contribute. The key is identifying the root problem to select an effective, lasting solution. Taking a methodical approach can save time and prevent repeated adjustments in the future, making the home safer and quieter overall.

Tips to prevent the door from rubbing on the ground
To stop a door from scraping the floor, several options exist depending on how severe the issue is and the user’s DIY comfort level. The following steps are practical and commonly effective for most homes:
- Adjust the hinges. If the rubbing is slight, the hinge screws may be loose. Tighten the screws with a screwdriver. If the screws are worn, replace them to restore proper alignment. After tightening, check the door swing and listen for a clean, quiet close rather than a telltale drag.
- Use sandpaper. For minor friction, remove the door from its hinges and lay it on sawhorses or another stable surface. Lightly sand the rubbing area with medium-grit sandpaper, moving with the grain to avoid damage. Check frequently as you sand to avoid removing too much material. Refit the door and test in place, paying attention to the final clearance at the bottom edge.
- Cut the bottom. When rubbing is more noticeable, trim the door’s bottom. Remove the door, draw a straight line along the cut area with a ruler, and cut using a hand saw, circular saw, or jigsaw. Smooth the new edge with sandpaper after cutting. Reinstall and test with the frame to ensure a level, even seal and a smooth closing action.
- Replace door or frame. If the door or frame is warped beyond repair, replacement might be the best option for a clean, even seal and operation. Modern doors and frames often respond well to precise fitting and can reduce future maintenance needs.
Always work safely. Wear protective eyewear and gloves when sanding or cutting, and seek help if moving or handling a heavy door. For stubborn cases, consulting a professional can prevent accidental damage and ensure the system aligns properly from top to bottom.
