Fixing a cracked door can be a relatively simple DIY project, depending on the extent of the damage. Here is a step-by-step guide on how to repair a cracked door:

Materials needed:


Wood filler

Putty knife


Paint or finish

Paintbrush or roller

Step 1: Prepare the Door Remove any hinges and hardware from the door so that you can work on it comfortably. If the door is already paint, use sandpaper to rough up the surface around the crack, making it easier for the filler to adhere.

Step 2: Fill the Crack Using a putty knife, apply a generous amount of wood filler into the crack. Make sure to push the filler deep into the crack, filling it completely. Allow the filler to dry completely, following the manufacturer’s instructions on the packaging.

Step 3: Sand the Filled Area Once the filler is dry, sand the filled area until it is smooth and level with the rest of the door. This step is important to ensure that the final finish looks seamless.

Step 4: Prime the Door Using a paintbrush or roller, apply a primer to the door, covering both the filled area and the surrounding surface. This step will help the paint or finish adhere to the door and create a uniform surface for painting. Allow the primer to dry completely.

Step 5: Paint or Finish the Door Finally, paint or finish the door with the desired color. You may need to apply a second coat if the first one is not enough to cover the primer. If you are using paint with a gloss or semi-gloss finish, make sure to let it dry completely before reattaching any hinges or hardware.

With these simple steps, you can repair a cracked door and restore its appearance to like-new condition.


If the crack is too large or the door is severely damaged, it may be necessary to replace the door altogether. In this case, you should consult with a professional carpenter or contractor for the best solution.

In conclusion, fixing a cracked door is a simple DIY project that can be accomplished in a few hours with a little effort and the right materials. Just remember to work carefully and follow the steps outlined above, and your door will look as good as new in no time!
