    I would try squirting a small amount of wood glue into the crack, then using blue tape to hold the piece in place until it dries completely. Use a bit of spackle to smooth out the edges after it has dried, sand and then touch up the paint. Probably won't be perfect, but should look pretty good.

    Wood glue and wood filler are my go to for problems like this. There are paintable wood fillers and glue that dries clear or white. A good sanding sponge and you should be good to go. Do you know what caused it? Maybe something is catching on it that could be minimized.

    Add some caulking around that area

    Minwax makes a wood epoxy just like wood filler and you mix it and put in the crack so it doesn't expand or crack anymore. Caulk will crack and so will plain wood putty.

    Try Bondo Wood Filler. I had to order mine on line because I could not find a store that had it. It's stainable and paintable.

    If you'd rather replace the piece it's a standard trim piece size from any big box store.

      What is damaged is the frame, not the door trim. The frame is interlocked with the header and difficult to remove and not available at Home Depot.

    I have fixed that same area. I used Bondo wood filler, but you could use Elmers also. I taped the area off and then filled in the cracks. I let dry completely, then sanded the area down. Mine needed 2 applications. When dry, you can prime and paint.

    Looks like you have maybe tried to use glue of some kind already? If that is the case, you must let it dry thoroughly and then plane it down flush with rest of door frame, before priming, undercoating and then painting.

  • I would get some wood glue into the crack and the press it down firmly, securing it with painters tape until it's dry.

    Wood glue, a $8 bar clamp from Amazon/Harbor Freight, and one nights' worth of patience.

    Hello, clean it thoroughly, let it dry, add wood glue to it and clamp it over night. I will look like new in the morning. Apply wood glue or filler into the cracked part of the door, ensuring you apply enough glue to reach deep into the crack. Next, use wood clamps to squeeze the door together while the glue solidifies. Leave the clamps on for a few hours to ensure the glue sticks. Lastly, remove the clamps.

    Hi Mary Ann: I agree, a bit of wood glue squirted under the crack and taping it down should work great. You can use some wood putty, stained to match, to smooth out the bumpy area, let it dry and sand smooth.

    You could use a good wood glue and clamp it, or cut out the area and insert a new piece of timber, or pin it from the side or Glue and Pin!

    After applying wood glue, I agree with the others who are advising you to clamp the area to ensure the areas are glued together well.

    You could take a bit of caulk or wood glue to fill in the crack! You may need to paint over it after to make sure everything blends in.

    This video should be helpful if you decide to use caulk!

    Carefully remove broken, split pieces of wood from bottom of the side jamb. Pull off any small splinters. Apply carpenter's glue to broken wood pieces and glue them back onto the jamb. Hold scrap wood block over the repair and use a hammer to tap the glued pieces tight to the jamb.

    Repairing a crack in a door frame can seem daunting, but with the right approach, it's totally manageable. One method involves applying wood glue into the crack, then clamping the frame together until the glue sets. After that, you can reinforce the repair with screws or nails for added strength. Another option is to use wood filler to fill in the crack, sand it down smooth, and repaint for a seamless finish.

    Wood filler and then paint over it, then you shouldn't be able to tell it was ever there.

    Hi Mary-Ann, hope this helps you.

    Fill in the crack with wood glue or wood filler. (Make sure you fill it as deep as possible.) After it's filled, use several wood clamps to squeeze the frame together and eliminate the crack. Leave your door open and allow the wood glue/filler to dry completely.
