The bedroom door creeps open at night, or the bathroom door swings shut every time you let go.

A door that swings open by itself, or drifts shut, is almost always hung on a hinge jamb that is out of plumb, so the door's own weight swings it toward the low side. JMB Builders fixes it across the Twin Cities metro by re-plumbing the hinge jamb, shimming or adjusting the hinges, or adding friction to a hinge pin. Priced per door, small jobs by the hour, quoted from photos.

A door on hinges is a pendulum. When the hinge pins line up straight up and down, the door stays wherever you leave it. When the hinge jamb leans, even a little, the door swings toward the low side every time. Lean the top of the jamb into the room and the door drifts open; lean it the other way and the door swings shut. That is the whole story behind most doors that move on their own.
Jambs go out of plumb for ordinary reasons. Houses settle, a floor sags in the middle, a wall gets pushed by a remodel, or the door was hung out of plumb to begin with and the shims never got set right. Sagging and dragging doors are a related problem with their own page; here the door closes fine, it just will not stay put.
The real fix is at the jamb. We pull the casing on the hinge side, check the jamb with a level, and reset it plumb on new shims nailed through to the stud. When the lean is small, adjusting the hinges is enough: a shim behind one hinge leaf, a long screw through the top hinge into the stud, or a hinge pin with a little friction. Rubber doorstops and magnets hide the problem; they do not fix it.

How it is priced: per door
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- A hinge adjustment vs. pulling the casing and resetting the jamb
- How far out of plumb the jamb is, and whether the floor or wall is the cause
- Stain-grade casing that has to come off and go back without damage
- Number of doors done in one visit
- Solid-core or heavy doors that need new hinges
- Painting or touch-up on reset casing, quoted as its own line
A ten-second video of the door drifting and a photo of the hinge side usually tell us whether it is a hinge fix or a jamb reset.
How long it takes
A hinge adjustment: under an hour per door. Pulling the casing and re-plumbing the hinge jamb: one to two hours per door.

Situations and options
Door drifts open
The top of the hinge jamb leans into the room the door opens into. The fix is pulling the top of the jamb back to plumb, or shimming the bottom hinge leaf out so the door's swing line comes back straight.
Door swings shut on its own
The lean goes the other way. Same fix, opposite direction. Common on bathroom and laundry doors in older houses where the floor has settled toward the middle of the house.
Friction hinge pin
When the lean is slight and the casing is stain-grade or hard to remove, a hinge pin with built-in friction holds the door in place without pulling the trim. It is a fix for small drift, not a badly leaning jamb.
Doors that are supposed to close
Some house-to-garage doors have spring hinges on purpose so the door closes behind you. That is not a defect. We adjust the spring tension if it slams, and leave the self-closing hinges in place.
Door Swings Open by Itself — Jamb and Hinge Fixes for Drifting Doors: questions, answered
Why does my door swing open by itself?
Because the hinge side of the door is not plumb. When the hinge pins are not straight up and down, the door's weight swings it toward the low side, so it drifts open or swings shut depending on which way the jamb leans. House settling, a sagging floor or a door that was hung out of plumb are the usual causes. Re-plumbing the hinge jamb or adjusting the hinges fixes it.
How do you fix a door that won't stay open and closes by itself?
First we check the hinge jamb with a level to see how far it leans. A small lean is fixed at the hinges, with a shim behind one hinge leaf or a long screw through the top hinge into the stud to pull the jamb back. A bigger lean means pulling the casing, resetting the jamb plumb on new shims and re-casing. Then we check that the door still latches.
Does bending the hinge pin stop a door from swinging?
It can stop a small drift, because the bent pin adds friction in the hinge. It is a common trick, but it wears the hinge, can make the door hard to swing, and it does not fix a jamb that leans. A hinge pin made to add friction does the same job more cleanly, and for a bigger lean the jamb itself needs to be reset.
Can an out-of-plumb door be fixed without replacing it?
Almost always. The door is fine; it is the jamb or the hinges that lean. Resetting the hinge jamb on new shims, or adjusting the hinges, brings the swing back straight. Replacement only makes sense when the door is damaged too, or you are replacing doors anyway.
Why did my door start swinging on its own after years of being fine?
Something moved. A floor that settled, a remodel on the other side of the wall, a heavier new door on old hinges, or hinge screws that loosened in the jamb can each tip the hinge line a little. Check the hinge screws first; if they are tight and the door still drifts, the jamb has moved and needs to be re-plumbed.
Can you fix every door in the house that swings on its own in one visit?
Yes. When several doors drift, the cause is often the same, such as a settled floor in the middle of the house. We check each one, fix the ones that need it at the hinges or the jamb, and make sure each still latches. Several doors in one visit costs less per door than one-off trips.
