Needed Tools And Supplies:

  • Wood glue
  • Wood filler
  • Pry bar
  • Wood clamps
  • Sandpaper
  • Paint
  • Screwdriver

Check Your Door Condition:

To begin, determine the extent of the damage by assessing the condition of the door frame. Is it just a minor blemish or something more serious? It’s simple to fix a split or crack caused by normal wear and tear. Other instances, such as forced entry or warping, may need the use of a repair kit or the complete replacement of the door or door frame.

These instructions are designed to repair simple cracks and splits in the wood, so make sure that’s what you’re working with. Remove the trim from both sides of your door frame as the first step in repairing it. Using your flat pry bar, accomplish this.

Clean The Door Frame Appropriately:

Once you’ve determined that the damage is only a crack or a split, you’ll want to inspect the break and clean it well. Splints of wood are frequently seen in cracks. Scrape the wood splints away with a razor, such as a box cutter.

There could be dust or dirt as well. To achieve a perfect bond and hold, all of this must be cleaned before applying the wood filler and glue.

Use Wood Glue To Repair Split:

Perhaps the door frame has a split that needs to be closed. If this is the case, the best restoration method is wood glue. Make sure to put the wood glue as deeply as possible into the split. After applying glue, clamp the door frame in place and mend the split with wood clamps.

These clamps must be left in place until the adhesive is completely dry. This will take a couple of hours at the very least. Some sites, however, advise drying it overnight.

Fill Cracks With Wood Fillers:

Wood filler is the finest product to use for cracks that do not need to be closed but only need to be filled. You must carefully analyze your options when purchasing a wood filler. It would be great to use a water-based wood filler for indoor jobs.

This type is made primarily for indoor use and can be stained or painted. You’ll want to use a solvent-based wood filler for outdoor tasks. It’s made to be used outside and can be stained or painted. A putty knife can be used to apply the wood filler.

Fill the area, remembering that the substance may shrink slightly as it dries. Allow the wood filler to dry according to the manufacturer’s instructions thoroughly.

Sand The Door Frame:

After the wood glue or filler has cured, it’s time to complete by addressing the door’s and door frame’s cosmetic issues. You’ll want to sand the areas where the wood glue or filler was applied until they’re completely smooth. This can be done using a handheld orbital sander or by hand with sanding paper.

After that, check to see if the surface is clean and ready to paint. Apply a coat of primer and one to two coats of paint, if necessary.

What Are The Main Reasons For Door Frame Cracks?

Several circumstances and events can cause a door frame crack. Materials in floors and walls can expand and contract when a home is in an environment with high temperature and humidity variations. Heavy use or use over a long period can cause a door or door frame to crack.

When doors are frequently opened, shut, or banged, a split in the door frame or cracks in the door may emerge. A small crack could be repaired for a modest cost. It could be even cheaper if you already have some of the materials. On the other hand, repairing more serious damage could cost as much as you paid. If your door frame exhibits wood rot or has been forced open, causing a big break, this could be the issue.


The door and the door frame are two distinct elements in a house. A door can be pulled off its hinges and set aside if necessary while a door frame is removed and replaced. The door can then be returned to its original location. Repairing a fractured door or door frame may appear difficult at first, but it is pretty straightforward.

Cleaning the break, filling it with wood glue and filler, sanding it down, and repainting it can make it look as good as new in no time. Always remember to test your door once you’ve repaired it, and if the damage is more severe than a simple crack, you might want to try a few alternative methods to fix it.
