Putting up new interior doors in a house. I have a door that has probably a good 5/16" gap on the hinge side. The gap is wider at the middle of the door and closer to 1/8" on door top/bottom. Of course said door hits...

These are for new doors in old jams. We did chisel these out and out of the 12 doors the only issue. The hinges are lined up well and the hinge plates sit flat about 1/32" below door surface (and we made no modification to the framing).

This has us a bit stumped because when there is a hinge side gap that usually means our hinge is sticking out of the door and we just chisel off more... But not the case here.

Any pointers on this specific issue? Also it would be great if someone could address the easiest adjustments to make depending on where the gap is at. Basically looking for a cheatsheet I could give someone.

I will try to figure out your situation. You have only one door that has a good acceptable gap at the top and bottom, but a huge gap in the center. You have new door leaves you are installing, presuming the edges are still factory straight, or like factory straight, if you had to trim on the door to get it to fit the original jambs.. If the door has a 3rd hinge, the hinge in the easiest case, but not the best case, is just shimmed to meet the edge of the door leaf. It will be unsightly, but will work. The best case, would be to remove the trim at least on the hinge side of the jamb to get access to the shims, set the door in place, Do not install the pin in the middle hinge and shim the jamb over to get the barrel of the center hinge to line up, drop the pin in and reset the trim.

Yes, to me there is a science, perhaps a sequence is a good term too, either way it will give repeatable results. In existing door jambs, check the jambs in all fashions, plumb, straight, parallel, square at top. If the hinges are not in line, they MUST be to get good results. You can simply use a straight edge for this. No, it must not necessarily be plumb, but it should be close, ideally with in a 1/4" so it is not a self closing or opening door. To shim the hinge, I prefer NOT to shim under the whole hinge, just at the edge of the jamb. This angling of the hinge to get the pins to line up will allow one edge of the hinge to stay engaged fully into the original mortise. Which I think, helps keep the hinge looking proper in it place, as much as possible. Shimming in this fashion helps eliminate another problem of "hinge bind".

As a note, hinges should not be set 1/32" below the face of the jamb, it should be just the opposite, 1/32" proud of the jamb, this also helps eliminate hinge bind. When set this helps give a slight more room for the door at the jamb. When the hinges are inset, closes the gap smaller and perhaps may allow the door leaf to hit the jamb before it is closed fully at the hinge side (hinge bind). The hinge when set the way I suggest also allows for the painter to have an edge to follow when cutting in around the hinges, aiding in a neater paint job.

After the jamb is understood and the pins are inline, cut the door leaf to size if needed. Scribing the top to match the head jamb so the gap is even. Cut the sides if needed to get the slab to fit in the opening with the hinges folded into the jamb. This fitment MUST be snug, not tight. When the hinges are cut into the side of the door, the gap at the slam side will be created.

  • I am officially blaming this on cheap hinges. We adjusted the hinges while door was hanging with some big pliers and it fits almost perfect now. Was it really the hinges? Crap I don't know. I am literally sick of installing new doors in my flips but everyone loves it. What do I do to get things to fit? Plane the door or randomly do things until it fits. I am sure there is a science to this but I am not seeing much of a pattern. – DMoore Nov 5 '15 at 15:50
  • I added more detail to the answer to hopefully aid in your dilemma. – Jack Nov 5 '15 at 20:36
  • really good answer. We actually have a door cheat sheet for my crew and I added 3 things based on your answer. I think when I say there is a degree of randomness it stems from the door jambs (remember most are 30+ years old) are not plumb, maybe slightly warped, whatever - and this could be different on each side. Then most of the time the doors we get for flips are the hollow 6 panel. Well you know these aren't 100% true and they warp pretty quick. So dealing with a door warped at 5 degrees, a hinge jamb off by 3 degrees and a door stop off by 6 degrees... – DMoore Nov 6 '15 at 18:38
