Removal
Removing a door is one of the more straightforward tasks in this guide, but doing it carelessly causes damage that creates work downstream. This section covers removing a door slab, removing a full pre-hung unit, and removing hardware — in order from least to most involved.
Removing a door slab
Slab removal is the most common scenario: taking the door panel out of an existing frame, either for adjustment work or replacement.
1. Open the door to 90 degrees
Opening the door fully exposes the hinge pins and takes tension off the hinges, making pin removal easier. If the door won't stay open on its own, wedge it with a shim or doorstop.
2. Remove the hinge pins
Start with the bottom hinge pin. Place a flathead screwdriver or a nail set against the underside of the pin head and tap upward with a hammer. The pin should rise and can then be pulled free by hand. Repeat for the top hinge last.
Always remove bottom-up and reinstall top-down. Removing the top pin first leaves the door hanging at an angle from the bottom hinge, which puts lateral stress on the hinge leaf and can strip the screws.
If a hinge pin won't budge, check for paint. Doors that have been painted in place often have paint bridging the pin to the barrel. Score around the pin head with a utility knife before tapping. Never force a painted-over pin without scoring first — the barrel can deform.
3. Lift the door free
With both pins removed, lift the door straight up to disengage the hinge leaves and angle it out of the frame. Interior hollow-core doors are light enough for one person to manage. Solid-core and exterior doors are significantly heavier — have a second person ready to receive the door as it comes free.
4. Store the door safely
Lean the door flat against a wall on its long edge, not face-down on the floor where it can warp, or flat on an uneven surface. If the door will be out of the frame for any length of time, store it in a conditioned space. Wood doors left in a garage or unfinished space will move with humidity changes.
Removing a full pre-hung unit
Removing a pre-hung unit — door, frame, casing, and all — is necessary when replacing the entire assembly or when the rough opening is being modified. It's more involved than slab removal and almost always requires two people.
1. Remove the door slab
Follow the slab removal steps above. Working without the door in the frame makes everything that follows easier and safer.
2. Score the casing
The casing — the trim that covers the gap between the frame and the wall — is nailed into both the jamb and the framing and is likely painted over. Score along both edges of the casing on both sides of the wall with a utility knife before prying. This cuts the paint film and prevents tearing the drywall or wall surface when the casing comes free.
3. Remove the casing
Work a stiff putty knife behind the casing to break the paint seal, then follow with a pry bar. Use a scrap of wood behind the pry bar to protect the wall surface. Work gradually around the casing rather than levering hard at a single point — casing nails are numerous and prying too aggressively splits the trim and damages the wall.
Set the casing aside if it will be reused. Casing that has been on a door for years often fits the wall profile and paint lines better than new trim, and reusing it saves finishing work.
4. Cut any caulk or paint seams
Exterior door frames are typically caulked at the exterior where the brick mold or casing meets the siding. Cut this seam with a utility knife before attempting to pull the frame. Pulling against intact caulk tears the siding face.
5. Remove fasteners
Pre-hung frames are fastened through the jamb into the rough framing at shim locations — typically two fasteners per jamb side, plus the head. These may be nails or screws depending on the installer. Find them by looking for filled nail holes along the interior jamb face.
If they're nails, cut them with an oscillating multi-tool or a reciprocating saw with a metal-cutting blade inserted between the jamb and the rough framing. If they're screws, remove them directly.
6. Pull the unit
With fasteners cut or removed, the unit should pull free from the opening. Work it loose with a pry bar if it's stuck from caulk or paint, then walk it out of the opening carefully. Pre-hung exterior units are heavy and awkward — have a second person managing the exterior side.
7. Inspect the rough opening
With the unit out, inspect the rough opening before proceeding. Look for:
- Rot in the sill, jack studs, or header
- Evidence of water infiltration (staining, soft framing)
- Out-of-square framing that will need correction
This is the best opportunity to address any of these issues before a new unit goes in. Installing a new door over a rotted sill or damaged framing is a short-term fix that creates a larger problem later.
If the framing shows signs of rot or water damage, do not proceed with installation until the source of moisture has been identified and corrected. Replacing damaged framing without addressing the moisture source guarantees the problem recurs.
Removing hardware
Locksets
Most residential locksets are held by two screws on the interior rose or escutcheon plate. Remove those screws and the interior and exterior handles will separate. The latch assembly is held by two screws on the door edge — remove those and the latch pulls free from the bore.
If the screws aren't visible, the rose is likely a snap-fit cover concealing them. Look for a small slot on the edge of the rose, insert a flathead screwdriver, and pop the cover free.
Hinges
Hinges can be removed after the door is out of the frame. Remove the screws from the door leaf first, then the jamb leaf. If the hinges will be reused, keep the leaves paired — mix them up and the pin alignment may not match.
If hinges are painted over, score around each leaf with a utility knife before attempting to unscrew them. A painted-over hinge screw that's forced without scoring will cam out and leave a damaged screw head that's difficult to extract.
Strike plates
Strike plates are typically held by two screws and pull free once those are removed. If the strike is painted over, score around it first. Fill the mortise with wood filler if the new hardware won't cover it.
Next: Finishing
With the door removed, adjusted, or replaced, Finishing covers painting, staining, and preparing the surface for long-term performance.
