Door Frame Repair: Fixing Sticking & Out-of-Square Doors
A door that scrapes the frame, refuses to latch, or swings open on its own usually points to a frame that has shifted, swollen, or split. Exterior frames also rot at the bottom where rain and humidity collect, and interior frames crack when a door is forced or kicked. Left alone, a bad frame lets in drafts, water, and pests and can keep the door from locking securely.
The door frame, or jamb, is what the door hangs and latches against, so small problems there throw off the whole opening. Repair work ranges from re-shimming and re-securing a jamb that has drifted, to splicing in new wood where the bottom has rotted, to rebuilding the strike side after a break-in or forced entry. In older homes the rough opening itself may have settled, so the frame has to be re-squared rather than just patched. A correct repair gets the reveals even, the latch aligned, and the weatherseal tight again.
How the job is done
- 1
Diagnose why the door binds
We check the reveals around the door, test the latch, and look for rot, settling, or paint buildup. This tells us whether the frame moved, the wood swelled, or the hinges are the real culprit.
- 2
Remove trim and assess the jamb
Casing is carefully pried off to expose the shims and framing. We can then see if the jamb is rotted, split, or simply out of plumb against the rough opening.
- 3
Cut out and splice damaged wood
Rotted sections, common at exterior jamb bottoms, are cut back to sound material and a matching piece is scarfed in with exterior adhesive and fasteners. For full failure the jamb leg is replaced.
- 4
Re-plumb, shim, and secure the frame
We reset the jamb plumb and square using tapered shims behind the hinges and strike, then fasten through into the framing so it stays put under daily use.
- 5
Align the strike and latch
The strike plate is repositioned or its mortise adjusted so the latch and deadbolt seat fully. On forced-entry repairs we reinforce the strike area for better security.
- 6
Reinstall trim and seal
Casing goes back on, gaps are caulked, and exterior joints and end-grain are sealed and primed. We confirm the door swings, latches, and weatherstrips correctly before finishing.
What a pro checks
- Pros check the floor and threshold for settling first; a sagging header or sunken sill often masquerades as a swollen door.
- Exterior jamb rot almost always starts at the bottom inch or two where water sits, so that is where we probe with an awl.
- A frequent mistake is planing the door to fit a crooked frame, which only looks worse once the frame is corrected.
- End-grain on any spliced wood must be sealed; unsealed cuts wick moisture and rot again within a season in humid climates.
- On security repairs, longer screws into the stud behind the jamb make a far stronger strike than the short factory screws.
- Removing old paint buildup from the jamb edges sometimes solves a sticking door with no carpentry at all.

Frequently asked questions
Why does my door stick only in summer?
Wood absorbs moisture in humid summers and swells, so a door that fit fine in winter can bind in July. We can ease the fit and seal the wood so seasonal swelling causes less trouble.
Can you repair just the rotted bottom of the frame?
Often yes. If the rot is contained near the base, we cut it back to solid wood and splice in a matching piece rather than replacing the entire jamb. Extensive rot may call for a new jamb leg.
My door was kicked in. Can the frame be fixed and made stronger?
Yes. We repair or replace the split strike-side jamb and reinforce the area with longer screws and, if needed, a strike reinforcement so the door is harder to force again.
Do I need a whole new door if the frame is damaged?
Not usually. The door and frame are separate, so a damaged frame can typically be repaired while keeping your existing door. We will tell you if the door itself also needs attention.
