I moved my business into a new building, and there is a doorway i want to put up a door in it. However the doorway is about 1/4" narrower at the bottom, than the top. Neither of the top corners are square. I am looking for the easiest way with the least amount of work and knowledge needed to hang this door. It is only a barrier, it is not for security. It will be closed most of the time, so i am not worried if it is going to naturally swing open or closed.
Also, the cuts for the hinges on the door and the frame do not line up. I am fine with buying a new door, but I would rather not replace the frame of i can avoid it.
Any suggestions?
Are you aware that the door is upside-down?
The knob should be below the center point, not above it.
That aside, the best way to deal with your stated problem is to fix the frame. You don't need to completely redo it. Just figure out which side of the frame isn't straight up and down, get a thinner replacement piece for that side, and put some spacers under the top end. Then fill in the gap with some wood filler and paint it to match.
Alternatively use a planer or something similar to shave off some depth at the tighter end of that frame piece. I've used an oscillating multitool for something very similar. Getting it flat will be tricky but it's doable.
Flip the door right-side up first though.
Isn't just taking a plane to the door a solution too?
if its an interior door, theyre hollow inside
Depends on the quality of the door. My house was built in the 1960s and most of the interior doors aren't hollow.
I dunno, mine's a 70 and they're hollow and thin. But In this case, it sounds like they're trying to fit a new door in an existing opening, so I'm assuming its a hollow interior door.
It is a hollow door, but the amount of planing needed at the bottom is minor, I am more worried about the 1/4” gap at the top.
Hollow doors have about a 1" frame of solid wood around the perimeter.
There is at least some wood all the way around that you can shape.
In this case it would be more than enough.
There are already two planes.
More than two, those are entire stacks of mana I am using to hold the door in place. I also have a table with a short leg that is leveled with a stack of mountains.
~~If the door is hollow, you may reveal the cavity inside, which I suppose could be filled in with wood filler. But I don't think the result would be attractive.~~ disregard, below commenter is correct, and was replying to this paragraph ^
Another aspect of this solution is that the door isn't easily replaceable if it has to be planed like this. It's no longer a rectangle. A replacement door would have to be modified too.
That doesn't sound likely, there's usually a frame all around that is at least an inch thick, and probably more like a couple.
Right you are, I was thinking of the depth of the side pieces, not the thickness of the edge pieces.
Doing that could be fine for making more space at the bottom. It won't fix how the gap is too big at the top. But if OP doesn't mind, then no biggie.
The door is upside down because of the hinges. If I turn it left-side up the hinges face into the frame. When I redo the notches for the hinges I planned to flip the door, but since half are still on the door itself it will not go into the frame as is.
