Do you have a split door frame and don’t know how to fix it? What if you could save some money by fixing it yourself? Follow along below for a step by step tutorial on how to repair a split door frame!

  1. Identify where the damage is located. A split can occur in a variety of locations on the frame depending on how it was damaged. The most common area to become split is the middle, usually from potential burglaries or other forced door entries. Kicking a door can also cause a split lower but on the door frame.
  2. Remove the door strip and molding. The easiest way to do this is to use a chisel and hammer to pry the strip and molding away from the frame gently you don’t want to damage it. It is always better to start at the bottom and work your way up. Use the claw end of the hammer on the side of each nail evenly remove the remaining nails.
  3. Measure and cut. Mark at least 6 inches above the damage to allow you to repair without causing any more damage to the frame. Use screws to secure the remaining strip make sure you don not cut too deep and damage the actual frame. When you cut the new lumber it needs to be the same length and width as the damaged pieces, you also want to use the type of lumber to keep consistency.
    • The most commonly used type of wood is weather-treated 2×4.
    • Pressure-treated wood is never a good option as the wood will twist once it dries out.
    • Door frame/jamb replacement kits are readily available buy and modified as you need it.
    • If you are not certain what type of material your frame is made from take the damaged portion to the local lumber yard and as a expert.
  4. Putting the new lumber into place. Before adding the nails first use wood or carpenter’s glue to set the replacement pieces in place. After the glue is dry add two nails to the top and bottom of the new lumber to make sure it stays in place.
  5. Finishing the repaired area. Once the glue is dry and the nails are in sand away any glue residue and imperfections between the new and old frame. Fill in any gaps with wood filler, enough to cover the entire repaired area. allow to dry then sand till smooth, add primer and two coats of paint.
