How to Install a Pre-Hung Interior Door | Ask This Old House

I THOUGHT I knew how to hang a pre-hung door and have done many in my time. I followed Tom's procedures here and hung 3 Interior doors in less than an hour - they hang perfectly!! Thanks Tom!!

[@tycobb8621]

@Alan Reynolds same here. Hung probably 75-100 doors in my time so far. But Tommy's way is great and I still do it this way

[@unrescued]

I'm right there with you - I almost feel inclined to share this video with my old boss who taught me how to hang doors - the part about tacking the shims prior to installation is honestly a revelation to me

[@bryantaylor7137]

Same. I always used to shim the hinge side with the door in place. What a waste of time. Though I don't own a 7' level, so gonna fix that or use one of my 4-ft's attached to a 2x4. And will be using reference lines henceforth.

[@ecstaticbanana1063]

For those who are confused: At 1:58, tommy says that his line is at 58-1/4” on the hinge side. He is referring to the level line on the Sheetrock NOT where he marked the door jamb. He measures 7/16” down from 58-1/4” to account for tile and thinset and marks there so he actually marks the jamb at 57-13/16” from the bottom. He simply measures from the top of the jamb on the hinge side (21” to line on jamb) in order to find the measurement necessary in order to level the header. Then, he transfers that same 21” to the striker side which will give him a level header. Since the hinge side had a shorter measurement, he must cut the hinge side to fit. Hope this helps, it is definitely confusing in the video.

[@anthonyfrigo3357]

Mr. Langdon do you know how much he cut off and why ? Tbank you !

[@paulepling]

57 13/16, then since it was an inch out of level, 59 minus 57 13/16 is 1 3/16, but since the striker side was a quarter already still from the 59 1/4, 1/4 of that 7/16 is equaling it out, so really, a 3/16 of that 1 3/16 had to be taken into account for as extra height to be removed, so he only would've cut exactly an inch off, right? That would've given a perfect floor margin? Or is the original door height - the 7/16 to be 57 13/16 get transferred to the other jamb, and just cuts the inch out of level off. This is all assuming the gap on the striker side still has a 7/16 margin, when it didn't it was only a quarter, but where does that come into play?

[@paulepling]

There's nothing explaining the margin that already exists between the threshold area, bottom of door and jamb on the side that needs to be longer. shouldn't that be a variable?

[@savagesmallengine3991]

Recently, we replaced a 20 year old prehung, prefinished flush door because the previous door had a cat door cut into it. To our surprise the new replacement door (32”x80”) had the exact same hinge hinge placement as the old one. We originally planned to remove the oak trim from both sides and remove the old jam from the frame. However, all we had to do was to remove the old door at the hinges and reinstall the new door with the old matching hinges. The door fit like a glove! You’ve gotta luv industry standards that stand the test of time.

​@@Gitarzan66 leveling the floor is the slab pourer's job. Problem is, we've become accustomed to their shoddy work. I dont mind doing it. It pays decent if its extreme enough to be a mud job. With flooring, I'm more concerned with the surface being flat than level. A significant distinction. In less severe cases, I charge $50/hour plus materials to screed thinset or leveling compound.

[@jeffreyreisert4424]

Nice video includes showing how to correct errors in frame/floor. Thanks.

[@TheBasketballFanatic]

Not a total newbie but I’m lost at 1:58. 1. Why do you measure from the bottom of the door on one side and the bottom of the jam on the other? 2. How did you determine how much to cut off from the hinge side of the door? I understand you’re accounting for the unlevel floor and tile but the measurements are where I’m getting confused. Anyone else?

[@rethinkdaily9321]

Me too, and no one is answering that I can see.

[@rethinkdaily9321]

Here is what I'm assuming. He cut off the jam on the hinge side to leave the 17th inch for the tile. Since it just so happened that the jam on the handle side to the reference mark was 59 inches, he didn't need to cut. But if the floor was perfectly level, it wouldn't have been 59 inches, and he would have ended cutting off the same amount from the doorknob side that he did the Jam side. The floor was just really bad, so it made the example a little confusing.

[@Mr.Pop0]

The cheaper and faster way is to install the trim onto the front side of the door jamb before hanging up and nail the trim into the wall, then go in and shim and screw the jamb. It may be the C student way, but i got up 15 doors in a day that way. You would basically be using the trim on the door like the "quick door hanger" product.

[@vrea77]

Yep

[@Peter-976]

Yup, then you`re coming back in 1 year to rehang every door after it has settled, lol

[@billy9043]

How can you possibly do the trim first and get your reveal to be spot on?? This is NOT the better way to install in my opinion. If you want a professional/proper trim reveal, then you mark/measure your reveals, AFTER the door is installed to put on trim.

[@ecstaticbanana1063]

Split jam doors are typically done this way, but it doesn’t typically give you the best result as far as level goes and isn’t very adjustable. Doing it the way Tom does allows for a precise placement of the door. Nailing the casing might fly on production homes but will not work for high end custom homes.

Jambs are 1/2 inch longer than the door. You just can't cut off one inch from the jamb without making the door shorter. Look at the bottom of the door at 3:10 it was cut probably at an angle. They deleted this from the video. Why?

[@5280]

All this made sense until he shimmed the bottom at the end. I thought all the measurements and cutting the hinge jamb side accounted for the need to shim... What am I confused about?

[@ceruleansin77]

Because he added extra space for the tile under the door, there was space that allowed the door to sag on the handle side (left) and thus his line didn't match until he shimmed.

[@Nomago]

And likely he took those shims out after the striker side was screwed so tile could be later later.

I just got a job hanging doors. A coworker told me to watch you tube since I have not done this for 12 years. No body has had much success be fore me. The company before this worked for taught me to nail it on below the top hinge on a 1\2 inch block elevating for carpet with a 1\4 inch shim but not nailing the shim. Put the magnetic level on the hinges then put two nails above the bottom hinge with shims on top to level.look at the reveil of the sheet rock and spit the difference for sheetrock deceptively.easy right?.today was my third day when I realized the hinges were not screwed tight.Went back and tighten previous doors and they changed a lot and most of them were striped out. We do not put more than three shims in them because the painter's take all the doors off and never put them back in the same opening. My buddy told me that I worry to much. Watch this video and look at the praise in the comments. It worked. Nobody in real construction puts finished products till after the mudding and taping. The humidity will damage mdf unusable. Tomorrow I am tighting up the screws. Not telling anybody else because no good deed goes unpunished and will be able to get a lot more done. By putting the shims below the top hinge and above the bottom hinge all you have to do is take out a screw on the door side and adjust it to whatever you want. No worries.

How do you measure 21" from the top of the door and jamb, and then 21" from the top of the frame and still have a space at the top of the door? You had a couple inches easy when you had the door in place.

[@erikhilliard6914]

Stephen Hodge that measurement would have been greater than 21” from the top of the rough opening (frame) to the level marks on the opening (frame) he never measures from the top of the frame to the marks he makes with the level. He does that on the door to get those marks on the door level. The floor isnt level so he cant do that by measuring from the bottom of the door if that makes sense

[@jakemaddox76]

He mentioned aligning the door with the wall, but did he mention making sure that the door was plumb front to back? As in tipping forward or backward. What if the wall is not plumb that way either? I also have a transition between rooms that has oak hardwood to a ceramic tile. So the tile side is about an inch lower that the hardwood side. I'm guessing a contour gauge may be a good way to transfer the funky shape of that transition? The builder did it awful, basically hacked it out and just filled the space with caulk. The things you never notice in five years of living in a house that now bother you. Lastly, is screwing the frame in place preferred? I thought I've always seen them nailed. How many screws are required? Do you putty over and sand prior to paint?

[@JustinKais]

Good point. Forever having a door open or close by itself.

[@michaeldevaney2804]

Wouldn’t you always cut the jam on the high side since one cannot extend a jamb on the other side?

[@chrisburns5691]

yes

[@michaeldevaney2804]

I thought so. The explanation was very good but got a bit confusing. The simple rule of thumb is to cut jamb on high side and allow for any flooring material that might be added after door is installed

[@richardmendoza1120]

How’s much did you cut off the jam?

[@jakemaddox76]

So, this is pretty confusing and not well explained in the video. I calculated this out for over an hour, and my math is correct: - He adds 7/16" to 58 1/4" on hinge side. Hinge side jamb cut to the ref mark now on the jamb should be 58 11/16" in total length (remember we don't know how much he has to cut yet, just what length should be. Some people are saying subtract but no, at 58 1/4" the door would be flush to floor, take any more length off the jamb and game over) - We would want the strike side to be 59 11/16" due to 1" difference in floor height. - However, jamb ref point on striker side is only 59" in length to bottom of jamb. - This means that we're missing 11/16" from the jamb on the striker side. (He mentions in the video that "we're only missing 1/4" which is fine for tile." This is incorrect. Remember he added 7/16" for spacing at the bottom of the door, so we're using completely different ref marks at this point. We're not measuring on the door frame anymore, only the jamb) - Since ref marks are same on both sides, we now know that the uncut length on the hinge side is 59" also from the ref mark. - This means we need to cut 5/16" off of the hinge side jamb, assuming the jambs are the same length. - At this point, the hinge side would be resting on the floor and the striker side would be 11/16" off the floor and the ref marks on the jambs would match those on the frame. - If you wanted to add space to tile under on the hinge side, then you'd have to cut an additional 1/4", so instead of 5/16" cut off, it'd be 9/16" to cut off. Look at 3:09 in the video, no way in hell that is 7/16" from bottom of door to jamb. That's why when he shims the bottom of the striker side at 5:47 it looks way closer than 11/16" from jamb to floor.

this is what I don't understand as well. It looks like he shimmed up what he just cut off of the jamb.

[@angelf9800]

I read all this to understand and still confused cause I seen him cut the hinge side that already was lower. But I think I got it now lol

[@rethinkdaily9321]

I don't understand why one reference measurement is measured from the base of the door and the other is measured from the base of the jam. I'm not following that. How much did he cut off of the jam on the one side?

[@horriblespaghetti]

His reference line from the floor is 58.25 on rh side and 59.25 on lh side. You measure off the door because you can't have a big gap on the bottom. He goes up 58.25 + .5 inches on the rh side for the tile. The floor is out of level, but the top HAS to be level. 21 inches down from the top on rh side so the lh side is also 21 inches down from top. Finally on the lh jamb, he measures it at 59 inches from the bottom to the line. .25 inches shorter than. He needed, so he can't/doesn't need to trim it, he needs to trim 1" off the other side to clear the floor

So if I already have the tile installed, I don't need to do what he did on 2:00‽

[@andrewallen8764]

Some people say how great the video is but none of them can answer any of the many questions that folks have. He's a great Craftsman.... he's not the greatest teacher as he fails to mention exactly where he is measuring from why ???????

Master builder!!!!bravo

[@elephantgrass631]

With floors that out of level, would self leveling compound help?

[@GJLCreativeStudios]

you answered your own question, homie. Thats what the shits for

[@HB-wd8gp]

Self leveling compound is fine for cement floors before you tile, but not for wood floors.

[@chrisburns5691]

yeah really should have levelled that floor before installing the door.. now he will be laying floor that is out of level an inch just over the width of that doorway, lol..

[@elephantgrass631]

@@GJLCreativeStudios Yeah but THAT out of level? That was the question.
