Why is My Wooden Door Scraping the Floor and How Do I Repair It?
A wooden door scraping the floor is a common but frustrating household issue. Not only does it create an annoying noise every time you open or close the door, but it can also damage your flooring and the door itself. Left unchecked, the friction can lead to scratches on your floor, chips at the door bottom, or difficulty in opening and closing the door smoothly. Understanding the underlying causes and applying the right repair techniques is essential to restore both function and appearance.
In many cases, the solution may require professional expertise, especially when the cause is structural or complex. Companies like PS Handyman Singapore provide skilled carpentry services for door repairs, helping homeowners address scraping doors efficiently.

Their services include precise door realignment, hinge adjustments, and preventive measures that ensure doors operate smoothly for years.
- Common Causes of a Wooden Door Scraping the Floor
1.1 Seasonal Changes and Humidity
Wood is highly sensitive to changes in temperature and humidity. During humid seasons, wooden doors absorb moisture and expand, while in dry weather, they shrink. This natural expansion can cause doors to press against the floor, creating a scraping sound. Doors made of solid wood are especially prone to this effect, whereas engineered or composite doors are less affected.
1.2 Settling of the House
As homes age, the foundation and structural framework can settle slightly. Even minor shifts can affect door alignment, causing the door to tilt or hang unevenly. This misalignment is often noticeable when multiple doors in the home start scraping at different heights or appear uneven within the frame.
1.3 Loose Hinges or Sagging
Over time, screws in door hinges may loosen, or the hinges themselves may wear out. This can result in the door sagging on one side, making the bottom edge scrape the floor. Hinge sagging is one of the most common causes of scraping doors and can sometimes be resolved without major repairs.
1.4 Improper Installation
Doors installed without proper clearance from the floor or incorrect frame alignment can start scraping immediately after installation or after a few months. Mistakes in measuring door height, floor level, or frame width can leave insufficient space between the door and the flooring.
- Identifying the Exact Problem
2.1 Inspecting the Door
Before attempting any repairs, inspect the door thoroughly. Look for marks on the floor or scuffing on the door edge to determine exactly where the scraping occurs. Check whether the issue is along the entire bottom of the door or just a specific side or corner.
2.2 Checking Hinges and Hardware
Examine all hinges and screws. Tighten loose screws first and see if this improves the door’s position. If the hinges are bent or worn, they may need replacement. This step often resolves sagging-related scraping without further work.
2.3 Measuring Door Clearance
Measure the distance between the bottom of the door and the floor at several points. Ideally, there should be at least a few millimetres of clearance to allow smooth opening and closing. Tools required for this step include a tape measure, pencil, and sometimes a straight edge to ensure the door is not warped.
- DIY Solutions to Repair a Scraping Door
3.1 Tightening or Replacing Hinges
Remove the door from the frame if necessary.
Tighten all hinge screws, ensuring they are firmly secured into the door frame.
If screws won’t tighten, replace them with longer screws to secure the door more effectively.
For severely worn hinges, replace the entire hinge set.
3.2 Planing or Sanding the Door Bottom
Remove the door from its hinges and place it on a stable work surface.
Mark the portion of the door that scrapes the floor.
Use a hand plane or coarse sandpaper to remove small amounts of wood gradually.
Continuously test the door on its frame until it opens and closes smoothly.
Always remove less wood at a time to avoid over-cutting.
3.3 Adjusting the Door Frame
Minor misalignment of the frame can sometimes cause scraping.
Insert thin shims behind hinges to lift or level the door slightly.
Check that the door swings freely without binding against the floor or frame.
3.4 Fixing a Swollen Door
In humid climates, allow the door to acclimatise in a dry environment.
Use a dehumidifier or improve ventilation to reduce moisture content.
Light sanding at the bottom edge may help remove minor swellings.
- When to Seek Professional Help
While DIY methods are effective for minor issues, some situations require professional attention:
The door continues scraping despite hinge adjustments.
The door has warped significantly due to moisture.
Multiple doors are misaligned, indicating structural settling.

- Preventive Measures to Avoid Future Scraping
5.1 Regular Maintenance
Check your doors periodically for loose screws, sagging hinges, or new marks on the floor. Lubricate hinges with silicone spray or light oil to reduce friction and prevent sagging.
5.2 Controlling Indoor Humidity
Maintain indoor humidity between 40–60% to prevent wood from expanding or contracting excessively. Use dehumidifiers in humid climates or air conditioning to regulate moisture levels.
5.3 Proper Door Installation
Ensure that doors have adequate clearance from the floor during installation. Selecting materials suited for the local climate also reduces the likelihood of swelling or warping.
- Tools and Materials Needed
Tools: Screwdriver, drill, hand plane, sandpaper, measuring tape, shims, lubricants.
Safety Equipment: Gloves, goggles, dust mask.
Optional: Dehumidifier for moisture control.
- Step-by-Step Guide: Fixing a Scraping Door
Inspect the door to identify scraping points.
Check and tighten hinges; replace if worn.
