A sagging door can be frustrating. It may scrape the floor, stick when you try to close it, or leave uneven gaps around the frame. Over time, this problem can damage your flooring, wear out the hinges, and even affect your home’s security if it’s an exterior door.<\/p>\n\n\n\n

The good news? In most cases, you don’t need to replace the door<\/strong>. A sagging door is usually caused by loose hinge screws, worn hinges, or a slight shift in the door frame<\/a>. With a few basic tools and about 30\u201360 minutes of work, most homeowners can fix the issue themselves.<\/p>\n\n\n\n

Whether you’re dealing with a bedroom door, bathroom door, or heavy front entry door, this guide explains exactly how to fix a sagging door<\/strong> using proven DIY methods that work.<\/p>\n\n\n\n

\"sagging<\/p>\n\n\n\n

Quick Answer<\/h2>\n\n\n\n

If your door is sagging, start by inspecting the hinges. Tighten all hinge screws first. If the screws no longer grip, replace one of the short screws in the top hinge with a 3-inch wood screw that reaches the wall stud. If the problem continues, replace worn hinges or use hinge shims to realign the door. For severe cases, the door frame may also need adjustment.<\/p>\n\n\n\n

Why Does a Door Sag?<\/h2>\n\n\n\n

Understanding the cause helps you choose the right repair method. A sagging door isn’t usually caused by the door itself\u2014it’s more often the hinges or frame.<\/p>\n\n\n\n

Here are the most common reasons:<\/p>\n\n\n\n

1. Loose Hinge Screws<\/h3>\n\n\n\n

This is the number one cause of a sagging door.<\/p>\n\n\n\n

Every time a door opens and closes, the hinges carry its weight. After years of use, the screws can loosen or pull out of the wood. Once that happens, the door begins to drop slightly, causing it to rub against the frame or floor.<\/p>\n\n\n\n

Signs:<\/strong><\/p>\n\n\n\n

    \n
  • Door rubs at the top corner<\/li>\n\n\n\n
  • Visible gap around the top hinge<\/li>\n\n\n\n
  • Hinges move when the door is lifted<\/li>\n<\/ul>\n\n\n\n

    2. Worn or Bent Hinges<\/h3>\n\n\n\n

    Old hinges wear out over time, especially on heavy solid wood or steel doors.<\/p>\n\n\n\n

    Rust, corrosion, or bent hinge leaves can prevent the door from hanging straight.<\/p>\n\n\n\n

    You may notice:<\/p>\n\n\n\n

      \n
    • Squeaking hinges<\/li>\n\n\n\n
    • Uneven spacing around the door<\/li>\n\n\n\n
    • Door drops even after tightening screws<\/li>\n<\/ul>\n\n\n\n

      3. House Settlement<\/h3>\n\n\n\n

      Homes naturally settle as they age. Small structural movements can shift the door frame out of alignment.<\/p>\n\n\n\n

      This is common in:<\/p>\n\n\n\n

        \n
      • Older homes<\/li>\n\n\n\n
      • Areas with expanding clay soil<\/li>\n\n\n\n
      • Homes that experience seasonal humidity changes<\/li>\n<\/ul>\n\n\n\n

        When the frame shifts, the door may no longer fit correctly even if the hinges are in good condition.<\/p>\n\n\n\n

        4. Heavy Doors<\/h3>\n\n\n\n

        Solid wood, hardwood, and steel entry doors are much heavier than hollow interior doors.<\/p>\n\n\n\n

        Over time, their extra weight puts more stress on the upper hinge, causing the door to sag gradually.<\/p>\n\n\n\n

        5. Humidity and Seasonal Changes<\/h3>\n\n\n\n

        Wood expands when it absorbs moisture and shrinks as it dries.<\/p>\n\n\n\n

        High humidity can make the door swell, while repeated expansion and contraction may slowly affect hinge alignment.<\/p>\n\n\n\n

        This is especially common in:<\/p>\n\n\n\n

          \n
        • Bathrooms<\/li>\n\n\n\n
        • Laundry rooms<\/li>\n\n\n\n
        • Coastal areas<\/li>\n\n\n\n
        • Homes without climate control<\/li>\n<\/ul>\n\n\n\n

          Signs Your Door Is Sagging<\/h2>\n\n\n\n

          Not sure if the problem is a sagging door?<\/p>\n\n\n\n

          Watch for these symptoms:<\/p>\n\n\n\n

            \n
          • The door scrapes the floor.<\/li>\n\n\n\n
          • The top corner rubs against the frame.<\/li>\n\n\n\n
          • The latch doesn’t line up with the strike plate.<\/li>\n\n\n\n
          • You have to lift the door to close it.<\/li>\n\n\n\n
          • Uneven gaps appear around the door.<\/li>\n\n\n\n
          • The door swings open or closed on its own.<\/li>\n\n\n\n
          • Hinges appear loose or separated from the frame.<\/li>\n<\/ul>\n\n\n\n

            Ignoring these signs can make the damage worse over time.<\/p>\n\n\n\n

            Safety Tips Before You Start<\/h2>\n\n\n\n

            Although fixing a sagging door is a beginner-friendly DIY project, a few precautions will make the job safer and easier:<\/p>\n\n\n\n

              \n
            • Ask someone to support heavy exterior doors while you work.<\/li>\n\n\n\n
            • Keep fingers clear of hinge gaps when removing hinge pins.<\/li>\n\n\n\n
            • Wear safety glasses when drilling or chiseling.<\/li>\n\n\n\n
            • Work on one hinge at a time to keep the door stable.<\/li>\n\n\n\n
            • Avoid overtightening screws, as this can strip the wood.<\/li>\n<\/ul>\n\n\n\n

              Taking a few extra minutes to prepare can help prevent damage to the door or frame.<\/p>\n\n\n\n

              Before You Start: Diagnose the Problem<\/h2>\n\n\n\n

              Before reaching for your tools, identify where the door is rubbing.<\/p>\n\n\n\n

              Open and close the door slowly while watching the gaps around all four sides.<\/p>\n\n\n\n

              Use this quick guide:<\/p>\n\n\n\n

              Problem<\/th>Likely Cause<\/th><\/tr><\/thead>
              Top latch side rubs frame<\/td>Loose top hinge<\/td><\/tr>

              Correctly diagnosing the issue will save time and ensure you choose the right repair method.<\/p>\n\n\n\n

              Method 1: Tighten the Hinge Screws (The Fastest Fix)<\/h1>\n\n\n\n

              Loose hinge screws are responsible for most sagging doors. Every time the door opens and closes, gravity puts pressure on the top hinge. Over time, the screws loosen, allowing the door to drop.<\/p>\n\n\n\n

              Steps<\/h3>\n\n\n\n
                \n
              1. Open the door fully.<\/li>\n\n\n\n
              2. Inspect all three hinges.<\/li>\n\n\n\n
              3. Tighten every screw with a screwdriver (avoid over-tightening).<\/li>\n\n\n\n
              4. Pay special attention to the top hinge<\/strong>, as it carries most of the door’s weight.<\/li>\n\n\n\n
              5. Close the door and check if it aligns properly.<\/li>\n<\/ol>\n\n\n\n

                Pro Tip<\/h3>\n\n\n\n

                Use a manual screwdriver for the final tightening. Power drills can strip the screw holes if used carelessly.<\/p>\n\n\n\n

                If the screws spin without tightening, move on to Method 2.<\/strong><\/p>\n\n\n\n

                Method 2: Replace the Top Hinge Screw with a 3-Inch Screw<\/h1>\n\n\n\n

                This is one of the most effective repairs for a sagging door.<\/p>\n\n\n\n

                Standard hinge screws are often only about 1 inch long, so they grip only the door frame. Replacing one top hinge screw with a 3-inch wood screw allows it to reach the wall stud behind the frame, pulling the door back into alignment.<\/p>\n\n\n\n

                Steps<\/h3>\n\n\n\n
                  \n
                1. Remove one screw from the top hinge<\/strong> on the frame side.<\/li>\n\n\n\n
                2. Insert a 3-inch wood screw.<\/li>\n\n\n\n
                3. Tighten it slowly until the hinge pulls snugly against the frame.<\/li>\n\n\n\n
                4. Check the door alignment.<\/li>\n\n\n\n
                5. Test the door several times.<\/li>\n<\/ol>\n\n\n\n

                  Why It Works<\/h3>\n\n\n\n

                  The longer screw anchors the hinge to the house framing instead of just the door jamb, making the repair stronger and longer-lasting.<\/p>\n\n\n\n

                  Method 3: Repair Stripped Screw Holes<\/h1>\n\n\n\n

                  If the screw holes have become too large, new screws won’t grip properly.<\/p>\n\n\n\n

                  Fortunately, this is an easy repair.<\/p>\n\n\n\n

                  What You’ll Need<\/h3>\n\n\n\n
                    \n
                  • Wooden toothpicks or wooden dowels<\/li>\n\n\n\n
                  • Wood glue<\/li>\n\n\n\n
                  • Utility knife<\/li>\n\n\n\n
                  • Screwdriver<\/li>\n<\/ul>\n\n\n\n

                    Steps<\/h3>\n\n\n\n
                      \n
                    1. Remove the loose screw.<\/li>\n\n\n\n
                    2. Apply a small amount of wood glue inside the hole.<\/li>\n\n\n\n
                    3. Insert several wooden toothpicks or a wooden dowel.<\/li>\n\n\n\n
                    4. Let the glue dry completely.<\/li>\n\n\n\n
                    5. Trim the excess wood flush with the surface.<\/li>\n\n\n\n
                    6. Reinstall the screw.<\/li>\n<\/ol>\n\n\n\n

                      The repaired hole provides fresh wood for the screw to grip securely.<\/p>\n\n\n\n

                      Method 4: Replace Worn or Bent Hinges<\/h1>\n\n\n\n

                      If tightening screws doesn’t solve the problem, inspect the hinges closely.<\/p>\n\n\n\n

                      Replace them if you notice:<\/p>\n\n\n\n

                        \n
                      • Rust<\/li>\n\n\n\n
                      • Bent hinge leaves<\/li>\n\n\n\n
                      • Loose hinge pins<\/li>\n\n\n\n
                      • Cracks<\/li>\n\n\n\n
                      • Excessive wear<\/li>\n<\/ul>\n\n\n\n

                        Steps<\/h3>\n\n\n\n
                          \n
                        1. Support the door.<\/li>\n\n\n\n
                        2. Remove one hinge at a time.<\/li>\n\n\n\n
                        3. Install the new hinge in the same position.<\/li>\n\n\n\n
                        4. Tighten all screws.<\/li>\n\n\n\n
                        5. Repeat for the remaining hinges if needed.<\/li>\n<\/ol>\n\n\n\n

                          Replacing all hinges at the same time is recommended for older doors.<\/p>\n\n\n\n

                          Method 5: Install Hinge Shims<\/h1>\n\n\n\n

                          Sometimes the hinges are fine, but the door needs a slight adjustment.<\/p>\n\n\n\n

                          A hinge shim changes the angle of the door by a few millimetres.<\/p>\n\n\n\n

                          Steps<\/h3>\n\n\n\n
                            \n
                          1. Remove one hinge.<\/li>\n\n\n\n
                          2. Place a thin cardboard or plastic shim behind the hinge.<\/li>\n\n\n\n
                          3. Reinstall the hinge.<\/li>\n\n\n\n
                          4. Test the door.<\/li>\n\n\n\n
                          5. Add or remove shim thickness as needed.<\/li>\n<\/ol>\n\n\n\n

                            Even a thin shim can noticeably improve alignment.<\/p>\n\n\n\n

                            Method 6: Adjust the Strike Plate<\/h1>\n\n\n\n

                            Sometimes the door itself is aligned, but the latch no longer lines up with the strike plate.<\/p>\n\n\n\n

                            Steps<\/h3>\n\n\n\n
                              \n
                            1. Close the door slowly.<\/li>\n\n\n\n
                            2. Mark where the latch contacts the strike plate.<\/li>\n\n\n\n
                            3. Loosen the strike plate screws.<\/li>\n\n\n\n
                            4. Move it slightly up or down.<\/li>\n\n\n\n
                            5. Tighten the screws.<\/li>\n\n\n\n
                            6. Test the latch.<\/li>\n<\/ol>\n\n\n\n

                              Only a small adjustment is usually needed.<\/p>\n\n\n\n

                              Method 7: Plane the Door (Last Resort)<\/h1>\n\n\n\n

                              If seasonal humidity has caused the door to swell, trimming a small amount from the edge may help.<\/p>\n\n\n\n

                              Only do this after trying the previous methods.<\/p>\n\n\n\n

                              Steps<\/h3>\n\n\n\n
                                \n
                              1. Mark the rubbing area with a pencil.<\/li>\n\n\n\n
                              2. Remove the door.<\/li>\n\n\n\n
                              3. Use a hand plane or electric planer.<\/li>\n\n\n\n
                              4. Remove only a small amount of wood.<\/li>\n\n\n\n
                              5. Sand the edge smooth.<\/li>\n\n\n\n
                              6. Repaint or reseal the exposed wood before rehanging the door.<\/li>\n<\/ol>\n\n\n\n

                                Removing too much material can create uneven gaps, so work gradually.<\/p>\n\n\n\n

                                Common Mistakes to Avoid<\/h1>\n\n\n\n
