Pre Hung Interior Door Problems

[Darrell Bade]

Not sure if this goes in this forum, but I did not see one any more specific.

I am hanging pre hung interior doors in my basement. Following all the instructions I have found I have been nailing the hinge side up with it shimmed plumb and level then working around the door to get the gap right. My problem is that when I get all that right the door is not tight against the stop on the latch side when the door is closed. The door is tight against the stop at the bottom and out about 1/4" from the stop at the top. I cannot seem to get this shimmed out without moving the lock jam so that it is not flush with the drywall which will just cause me grief at trim time.

Can anyone tell me what I am missing?

Sounds like your door may be plumb but not your wall? Sometimes when hanging doors we compromise between the level/plumb and and what looks pleasing to the eye.

I have hung a few doors where we finally just set the level aside and hung them by eye.

We have also installed the casing on one side and then slide the door into the opening get it as close as possible with the level and nail it in place.

Good luck,

Craig McCormick

There are a couple of possibilities. One is that there is a slight twist to the door. The other is that there is a slight twist to the wall, which is more likely from what I've seen in construction. At that point, you can go all out and tear out drywall and studs and start over, or do what most carpenters do and split the difference. For the door to work correctly, it has to be plumb, level and square. Where it sits in the opening is up to you for looks. You may have to set it so that the jamb sits proud of the drywall on one side at the bottom, and a little proud of the drywall on the other side at the top. Then you can use a hand plane to shave the jamb down flush. I see a lot of carpenters then use a hammer to convince the drywall to sit flush with the jamb where it is proud of the jamb.

Post a pic.
My instinct is that the abutting studs that support yr jamb are out of plumb.

You should be shimming your jamb plumb. If that means your trim needs to cover the gap between the drywall and the jamb, so be it; that's what it's there for.

If you have time, you might consider using screws instead of nails. They make it possible to adjust the plumbness slightly, and (better still) they are easily removable. Not as fast as nails, but more controllable IMHO for guys like me, who are only hanging a handful of doors in their own homes.

Frankly if the door swings OK I would just pull the stops and reset them. Sure, things need to be fairly plumb and mostly level, but this is a door in a house, not NASA. If the door gap at the bottom works versus the floor, the door doesn't hit the floor or open/close on its own, then it may be plumb enough, and reseting the stops a bit may be easier than banging the wall around, building an extension jamb on one side an shaving the other side to meet the wall plane. I assume the walls are sheet rock? Sometimes a whack on the bottom wall plate on the lock side with a sledge and a banger block can "encourage" the opening to more closely resemble plumb if things are a bit too far out to work.

I have an old house with 6 piece trim on both sides of all jambs, all of the head casings jack mitered in, plaster walls, and wainscot abutting several openings. With all that infrastructure to deal with I have come to accept what I have for a jamb. You can shim hinges a bit, you can actually "bend" the hinges a bit to move things around, you can play with stops, you can mortise one hinge a bit further back from the edge of the jamb. Lots of room for a little "english" if the walls won't behave.

i agree with shawn on using trim head screws. i use the ones from mcfeelys.

i also have a +100 year old house. no walls are level, or plumb, or even flat, there are humps and bumps everywhere since it's plaster. if the casing has to be twisted a bit to make the trim flush against the wall and the door frame, so be it. screws will pull it up.

I replaced 4 doors on the main floor of our house last year not one could be level. If I leveled the door frame then the gaps were all out of wack and the door was in the opening cock-eyed. So I just got it as close to level as I could and made all of the gaps the same. All of the doors work fine close nice but 2 of them when they are more than half open they wont stay they will open all of the way up. No big deal. That is what happens with 50 year old houses. MY parents 110 year old house is worse yet.

I have tried two doors. The first one the wall was as plumb as could be, but I did something with the bottom plate when framing that made me think that was the problem. To fix it I just cocked the jamb a little and was going to do the shave the drywall and work on the jamb to get it trimmed. Then I did another one and had the same issue. The framers did that wall and it was out of plumb a little bit. I hung the hinge side twice, once with the frame plumb and once with the hinge side out of plumb but following the wall thinking this would take care of it. No luck so I thought maybe I was doing something wrong. Have 3 more to hang so if I was doing something wrong I wanted to find out before continuing.

Houses are rarely plump and square, even the day after they are built. Older houses are worse in many cases than new because things sag over time. I agree with Jason though, split the difference before nailing the door in place, but unless you want a self closing or self opening door, make the hinge side plumb in two directions.

This is a common problem and easy to fix (as long as the stops are just tacked to the jamb and can be easily removed). Set the door so it swings freely inside the jamb, making sure the jamb is optimally positioned relative to the drywall - don't worry about the stops yet. Once the door is in place, pop off the stops and reset them against the door face at a position that allows the door latch to spring into the strike plate hole.

Hope this helps.

You should never have to move the stops.
The problem is the bottom plates are not aligned, or the door is warped or twisted.
Make the jambs align with the drywall at the top on both sides. This will make the mitres fit better.
Move the jambs in or out at the bottom of the door, a little on the hinge side, and a little the opposite way on the strike side.
Hold a piece of casing up on the side jambs with the correct reveal, and mark the outside of the casing on the wall.
Then beat down the drywall where needed, staying inside the line.

I hung a couple prehung oak doors yesterday. "Seemed like the same problem as you", but basically the door frame was just slightly twisted sitting in the rough opening. Straightened out the legs of the jambs, pulled in and out just slightly on the top corners of the frame where it is close to the drywall / studs, and everything was perfect.

Try very slightly moving the top corners of your frame in and out from the wall surface - bet you see a big difference. Larry

Damaging the drywall to fit the jamb is not recommended. Every pre-hung door I've installed came with the stops LIGHTLY tacked to the jamb so that they can be easily popped off and adjusted to the door face in situations like yours. Everyone has their preferred method, this is mine and I've found it to work well.

I have an unsquare old house too... I like to install the trim on one side of the door jamb before I even install it in the doorway. If the opening is in old plaster then you will want to grove the back of the trim and scribe it to the plaster. Then, shim the door in the normal way but don't nail it through the jamb yet, nail it through the trim. Then recheck (it shouldn't have moved), then take the hinges off and screw through the jamb under the hinges, then put them back on. Recheck, then nail, then install the trim on the other side.

I find that this method works perfectly for me, and avoids the problem of racking the jamb when nailing it. It gets a lot harder if you don't have wide trim, though.

Not recommended by who?
Scott, I've hung probably close to 2,000 pre-hung doors in my life, and none of them have the stops "lightly tacked". But my doors come from suppliers to professional builders, so I can't speak to the source of your doors.

The stops are applied to maintain the same distance from the outside face of the door blank, to the edge of the jamb. That is flush, or nearly so. A 1/4" deviation from the top to the bottom of the door WILL be noticeable, and unprofessional looking, and will create a problem at the strike.
I can assure you that "adjusting the drywall", rather than the stops, is the time honored method used by professionals. And will result in a more professional look when done properly.

As I mentioned earlier, it is best to do the adjustments at the bottom of the door. Making the top jambs flush with the drywall, will make the casing miters easier because the trim will lay flat on the wall and the casing.
