Door Will Not Close All the Way: What Actually Moved
What this comes down to
- The gap around a closed door is the reveal. An even reveal means nothing has moved.
- Where the reveal tightens says what moved: the hinges, the frame, or the door itself.
- One manufacturer allows a frame to be out of plumb by an eighth of an inch, no more.
- A door that sticks only in the humid half of the year has swollen rather than dropped.
- A long screw through each hinge into the studs fixes most dropped doors.
- A door that has never closed since the house settled is a framing question.
An eighth of an inch is the number that matters. One manufacturer will not hang a replacement door in a jamb further out of plumb than that. It is about the thickness of two stacked quarters.
Which is why a door that will not close is rarely about the door. It is reporting a small movement somewhere else, and the gap around it says where. Reading that gap costs nothing and settles most cases.
What is the gap around the door telling you?
Almost everything worth knowing. The gap between the door edge and the jamb is called the reveal. An even reveal means the door and the frame still agree. Close it slowly and watch where it touches first.
- Tight at the top corner on the latch side. The top hinge has pulled.
- Tight down the whole latch edge. The frame has moved, or the door has swollen.
- Tight along the bottom edge, sides still even. The floor has lifted, or the sill has.
- Even reveal, still will not latch. The strike plate is out, not the door.
- Reveal that changes with the season. Moisture, not movement.
Why does a door stick only in summer?
Because the timber has taken up moisture from the air and swollen. Wood changes dimension only below the fiber saturation point. Above that figure it is dimensionally stable.
The USDA Forest Products Laboratory explains why timber moves seasonally. Wood in service meets both seasonal and daily swings in relative humidity. Its moisture content follows them, and so does its size.
The local pattern is easy to check. The National Weather Service puts the wettest months here in late spring and summer. Normals for O'Hare give May 4.49 inches against 1.97 inches in February. Rainfall is not humidity, but the season is the same one.
Is it the hinges, or is it the frame?
The hinges, most of the time, and one test separates them. Lift the handle while the door is nearly shut. If the door rises and the tight corner opens up, the top hinge has pulled.
A dropped hinge is almost always a screw problem. The short screws supplied with a hinge reach the jamb and stop there. The jamb is thin timber shimmed off the framing, so it pulls forward under load.
JELD-WEN's installation instructions give the tolerance for plumb as an eighth of an inch. They call for a two and a half inch screw at each hinge, driven past the jamb into the studs. Shims go at the fixing holes and between the strikes.
What if the door closes but will not latch?
Then the strike plate is the suspect rather than the door. Color the latch bolt with a pencil, close the door against the strike, and open it again. The mark left on the plate shows where the bolt is arriving.
High or low by a small margin is a strike adjustment. Off by more than the plate can be moved means the door has dropped. The hinges get dealt with first. Moving a strike to chase a dropped door hides the cause.
When is the house the problem rather than the door?
When the frame itself is out of square, and the door has simply reported it. Frames go out of square from settlement below or from load arriving on the header above.
- Reveal wedge-shaped from top to bottom, wider at one end than the other
- Drywall cracks running diagonally from the top corner of the opening
- Several doors in the same part of the house sticking in the same season
- A door that has never closed properly since a particular winter
- A rotted sill or subfloor letting the frame settle at one corner
One door out of square is a door. Three doors out of square along one wall is the wall. That difference decides whether this is an hour of work or a structural conversation.
Can rot make a door stop closing?
Yes, and it is the case most often missed on an exterior door. A jamb with a soft foot no longer holds the bottom hinge. That hinge pulls and the foot of the door swings across. The reveal then closes at the bottom rather than at the top.
The check is a probe rather than a look. Push an awl into the bottom few inches of both jamb legs. Sound timber stops the point, and soft timber turns the job into a jamb repair.
Does a door that will not close matter beyond the annoyance?
It does, on an exterior door, for two separate reasons. The first is that the door is no longer sealing. The second is that a latch which does not throw fully is not a lock.
The Department of Energy's air sealing guide is plain about where air actually leaks. It puts gaps around windows and doors among the most obvious. A door held off its stop keeps that gap open in every season.
The security half is simpler. A deadbolt that cannot extend into the strike is decorative. A door forced shut against its stop also loads the hinges. That is what turns a small drop into a larger one.
What does each fix cost?
Most sticking doors land between the $99 minimum and a couple of hours at $65. The figures below are starting prices rather than quotations. The middle column is the wider market, for scale, and the last is what moves a job within its range.
| The work | Starting price | Wider market | What moves it |
|---|---|---|---|
| Minimum service call | $99 minimum | $120–$200 typical | Whether hardware is replaced on the day |
| Hourly rate after that | $65 per hour | $60–$125 / hr in Illinois | How many doors, and whether hardware comes off |
| Sliding or patio door repair | From $175 | $200–$700 | Rollers, track condition, and the weight of the glass |
| Door jamb repair | From $195 | $200–$600 | Whether the door has to come off its hinges |
| Full jamb or frame replacement | From $449 | $500–$1,200 | Siding removal, and what is found behind it |
| Exterior door replacement, installed | From $695 | $800–$2,500 | Door type, and whether the opening needs work |
Most of what this article describes lands in the first two rows. A dropped door with sound timber around it is an hour of work. That is priced by the hour rather than a door job.
What cannot be determined from the outside?
Three things, and each of them changes what the job actually is. None of them can be settled from a photograph or over the phone. A price given that way is a guess rather than an estimate.
Whether the jamb is packed to the framing. Shims sit behind the casing, out of sight. Until the casing lifts, nobody knows whether a hinge screw has anything solid to reach.
Whether the timber at the jamb foot is sound. Paint hides decay well, and a fresh coat hides it better. A probe settles it in seconds, but somebody has to be at the door with an awl.
Whether the opening is square or the floor is. A door can be hung true in a frame that is not. Confirming that means a level and a long straightedge across the opening.
Frequently asked questions
Should a sticking door just be planed?
Only once the reason is known, and rarely in the wet season. Planing a swollen door in July leaves a visible gap in January. If the door has dropped rather than swollen, planing removes timber that was never the problem.
Why do longer hinge screws work?
Because they reach past the jamb into the framing behind it. A short screw grips only the thin jamb, which is shimmed off the studs and can pull forward. A long screw ties the hinge to structure rather than trim.
Can a door stop closing after new flooring?
Yes, and it is a common cause. Added floor height reduces the gap under the door, so it binds at the bottom or on the threshold. The reveal at the sides usually stays even, which is the clue that nothing structural has moved.
When does Perfect Work recommend replacing rather than adjusting?
Perfect Work Remodeling & Repairs adjusts first. That holds wherever the timber is sound and the opening is square. Replacement is recommended when the jamb will not hold a fixing. It also applies once the frame has moved beyond what shimming can correct.
What a sticking door visit covers
The visit starts with the reveal and the contact point, then works back. Hinges, screws, shims, the strike and the jamb feet are all checked. So is the squareness of the opening.
What comes back is a written scope of work. It says what moved, what was corrected on the day, and what could not be confirmed. The visit and the work are done by the same small crew, on a door or out on a deck.
Perfect Work Remodeling & Repairs covers a door that will not close across DuPage County. The office is in Carol Stream. The crew that assesses the work is the crew that does it, with no subcontractors in between.
Homeowners describe how those jobs went in their own words. There is no charge and no obligation for the visit. Call 630-297-7888 or request a door visit to arrange one.
