- Shims [amzn.to/2w6ypUm]
Tools for How to Install a Pre-Hung Interior Door:
- Level [amzn.to/2JMPAlV]
- Nail gun [amzn.to/2HxNQds] or hammer [amzn.to/2HxNQds]
- Measuring tape [amzn.to/2WNrHOV]
- Circular saw [amzn.to/30r3foG]
- Drill/driver [amzn.to/2VvOsp8]
Steps for How to Install a Pre-Hung Interior Door:
1. Use a level to find a level spot on the rough opening. Mark spots on both sides of opening with a pencil.
2. Measure down to the floor on the hinge side using measuring tape, and note the measurement.
3. Measure down to the floor on the striker side, and note the measurement.
4. Hook the measuring tape on the bottom of the door on the hinge side, then measure and mark the height noted earlier.
5. Measure from your mark to the top of the header, then measure that same distance on the striker side to ensure the header will be level.
6. Hook the measuring tape under the striker-side jamb and measure up. The difference between the measurement from the rough opening to the mark on the doorjamb is the amount that will need to be cut out of the jamb (depending on the door, one or both jambs may need to be cut).
7. Use a circular saw to cut the jamb(s) to the desired lengths.
8. Use a level to ensure the rough opening is plumb on the hinge side. If not, nail an appropriate number of shims into the rough opening to make it plumb.
9. Move the door in place and keep it flush with the outer wall.
10. Pre-drill a hole and drive in a screw at the top on the hinge side.
11. Check the jamb to see if it’s plumb using a level.
12. Finish screwing in the hinge-side jamb using a driver.
13. Line up the two reference lines on the striker-side jamb.
14. Use shims down the hinge-side jamb to level it off, and drive in screws with a driver.
15. Break off the shims.
16. Put on trim using a nail gun or hammer.
17. Install door-knob hardware.

How to Install a Pre-Hung Interior Door | Ask This Old House
/ thisoldhouse
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!!
@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
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
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.
There's still a inch difference underneath the door
@@tycobb8621 there's still a inch difference under the door
"Came out really good, I love it" - and the academy award goes to...!
This man is about the only person I can listen to and completely understand what he's saying. Seriously. Thank you. I'm refurbishing my dad's house and am doing a pretty good job....because of these many videos. Yippie.
I love this because it’s genuine. No script at all. “ I love it”.
😂
A very comforting voice saying "you got this. I'll be here next to you the whole time."
I now feel ready for this job.
Now they should do a follow up episode where Justin goes back to his home planet and teaches everyone else how to hang a human door.
🤣
Ha! Poor guy was nervous as hell. That happens when the red light comes on
He just doing everything he can to hide the fact that he eats people
This comment killed me.
I’m cackling
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.
Mr. Langdon do you know how much he cut off and why ?
Tbank you !
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?
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?
Exactly what I was looking for, thanks!
This comment and @Paul Epling those numbers would be way easier to understand if you used metric
good to see Tom sharing his library of knowledge with the kids, we need more kids doing this.
I've been doing interior doors the hard way my boss taught me. This video was pure enlightenment. My old boss used to get mad if I used reference lines. Turns out I had the right ideas and intentions and was scared away from it.
Wait, we have the same boss?
@@sciencebuddy4096 possibly 😂 granted he was smart but he had his way, and I had mine.
I've a need to meticulously dissect everything. He hated that.
That's why some bosses probably never hung doors before and think they know what they are doing and talking about.
The real proof is when they do a door all the way to the end and the door closes perfectly... To the end!
This helped me and fiancé hang a door with absolutely 0 experience. Thank you so much
It's cool that they helped Eminen hang that door
"Thanks for the help Tom". Ya right. I think he means " Thanks for doing it for me Tom".
That's why I never learned anything as a kid. My grandpa would just do all the work and then say, "You got it, right?"
I didn't have it, but I love him anyways. Thankfully there's TH-cam now.
I laughed too hard at this comment. 😂😂😂
It's not rocket science. You don't need to do it to learn
@@roberthughes2687well now since you brought up rockets …. I think our boo Justin here might have some expertise in that field 👽
Nice video includes showing how to correct errors in frame/floor. Thanks.
This fella is displaying the definition of "Slow is Smooth, Smooth is Fast"
Great tips. Concise and to the point. Out of about a dozen videos I saw; Tom's the only one who actually plumbs and measures BEFORE drilling and setting jamb; what a pro. And thanks for the tip :)
The Best prehung door video I have seen ...hands down. He obviously is an awesome old school pro. Well done sir and thank you.
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.
Thank you! Thank you! After 3 generations of bedroom doors I have finally learned how to hang a door properly thanks to your video! Excellent tutorial! :)
Your bot supposed to have a inch difference underneath the door
perfect video. I love how Tom is so calm and methodical, makes it so easy to understand!
You don’t see him between takes 6 and 7 😂
thank you teacher, you with your videos have contributed to me putting bread on my childrens table,thanks a lot
0:55 Floor is not level, so mark a level reference line across rough opening
1:15 Measure to determine jamb length
1:30 Measure and mark jamb for cutting
3:00 Cut jamb to proper length for level installation
3:15 Shim so trimmer studs are plumb
4:00 Fit door in rough opening using reference lines
4:50 Screw hinge side jamb to trimmer stud
5:30 Shim to level Striker side of jamb
6:00 Close door to check reveal, then shim and screw striker side jamb
6:30 Install door casings
U must have no life
You left out 4:02. Mash finger in door.
Lmao I was like wait so he cut the jamb and then shimmed it? Lmao
This could be helpful
My dad built our house with help from his friends. He's just like Tom when it comes to carpentry and plumbing. The down side to me he's just like Chef Ramsay if you don't understand it the first time.
i can relate to that
Isn't everyone's father like that?
Keith Upton
+Kathryn Joyner Yes?
aha thats genius
This video was so helpful. I'm terrible at this kind of stuff, but I was able to install my door and it works great. I'm grateful for these guys.
There's still a inch difference underneath the door
While the door I was hanging was in a weird spot and probably would require a custom door to actually fit properly... I was able to follow this video and a few add ons to hang my first door that's plum and level! Thanks so much for sharing your expertise with us!
I "found" this video today - a very time appropriate because I have five doors to hang in my family room / guest room / bathroom area. You have saved me a whole lot of "figuring." Thank you.
Seen 10 vids so far. This one's best explained
On the hinge side, why do you measure up from the bottom of the door, not from the bottom of the jamb?
Thank you!! We are putting doors in and have unlevel floors throughout this old house of ours. This video really helped us, we have watched it multiple times and pause it while we work on each step.
There is still a inch difference under the door this is incorrect
just installed 6 interior doors for a happy customer thanks to "This Old House"!! Makes installation a breeze 😀 😎
This is the only video on TH-cam that shows the proper way to hang a prehung door We use to snap level lines through miles of office interiors years ago to do the exact same thing 👍🏻🔨
These guys are true craftsmen. So much knowledge ! love all of This old house videos!
There's still a inch difference underneath the door
the old house is the man make learn understand very very simple
thank you sooooooooooooooooooooooooooooooooooooooooo much for your valued videos that helped me very much
Aya Noah HURRRRP
tom silva is incredibly concise!!
I'm 100% positive Justin is a Machine.
GetGood no, just a bad actor
A robot or peewee herman 🤔
Or an android sent from the future or a great actor
I'm 98% positive he's Sheldon Cooper's evil twin.
I know a couple of people like that...
level the floor first especially under the door area and install the tile then install the door so the gap under the door is not ugly
Travis B problem is.. he gaped it to a unfinished floor. Now when they put flooring down they will have to trim door bottom.
I've been in the Bizz for almost 30 years, new houses. Trim/doors first then tile. Leveling the floor is the flooring guys job. Better to have a level door to begin with.
The video was made for floor without tile. Period! Installation of the tile has nothing to do with Technics to install door. These Technics are great.
@@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.
Tom Silva makes everything so easy.
Tom you are the bomb! This is the best tutorial on door hanging ever. Thank you so much
Very helpful...thanks guys!!
"came out really good, I love it"
Great video. Good tips and step-by-step visual and verbal instructions. I put the laptop on pause for each step. Plumb and hung alone! Thank you Tom!!!
Love all the episodes aired throughout the years! Wondering if you can do an episode demonstrating how to switch the hinges of an interior door to be on the inside of a room rather than the outside (wrong side in our fixer upper) of the room as well as the direction the door will then have to swing? Thank you for your ethics, good humor, sharing of soooooooooooo much knowledge and expertise! Much respect!
Tom the only thing I missed is how much did you trim off the hinge side jamb in this example? I know the two sides were off by 1" and you accounted for flooring but I lost how you came to a trimmed length. Thanks
Agreed. Maybe it was that 1 inch?
I am literally getting ready to install a door exactly the same.
Great video thanks!!
Love this. I'm a part-timer DIY and my method would have taken an hour longer. Done in a snap.
Experience makes things look easier
What a GREAT video. Thank you for taking the time to put this together.
It came out really good I love it.
Tommy I love you, great method, and common sense
This homeowner is just like “durrr” the whole time
Nice job Tom nice job!!
Nice job. I thought, however, you first fill the holes and then prime. That way there is no flashing or dull spot where the filler was.
Can't wait to try this out! I have 6 pre hung doors to do!!! I should be old hat by time I get them in.
Best door hanging video.
Wow he made it look so easy.
Still gotta carefully remove the old door frame, but this looks easier than trying to replace a missing door in an old beat up frame. Got the new door ready to go, looking forward to the learning experience. Thanks for sharing!!
What type of drill bit is that at 7:03?
Master builder!!!!bravo
Thanks for the help Tom. 🤖
This guy is a super pro! I am very impressed with this.
I can install any door without a level. Master Carpenter of over 40 years...
Especially those split jambs
Why does he still have a inch difference gap below the door
Nice and simple instructions. Watched different video and the guy recommended pounding in wall framing with sledge hammer if it wasn't level and I was like isn't that what the shims are for.
lol what da fug...
I thought I knew how to hmang a door learned a few things there. Genius!
It’s only one inch out of level in that respective area. The whole subfloor is probably 6+ inches out of level if it drops just one in in a 2 foot span
What size counter sink and screws are you using to mount the frame?
This is what I'm here for!
I was half-expecting Wolverine to make a dramatic entrance when he said "Stryker".
What is the point of cutting if you are shimming the striker side from the bottom. I'm an absolute newbie at home renovation, so this is all new to me.
wow Justin sure has an amazing personality !
Great video, very helpful for this first timer. But I can't help notice the bottom of the door doesn't look level at the end.
Thanks Tom!
Thanks Dad!
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?
Now Justin has a new closet to hide the bodies. Thanks, Tom!
On the next episode of this old house Tom shows Justin how to install sound proofing on the inside of the closet.
Really good straight forward video, I've been struggling with a door for 2 hours, I wish I would have watched this first
very good explanation and simplified to get the right stuff done
That man is a very good carpenter
I’m working with the Carpenter who sort of understand this principle get it right in the end but it takes forever to hang the door this method is so fast and so much better I just hung 10 doors I wish I’d seen this video first
He makes that an easy way for a home DIY er
Tom is the Boss!
Don't fuget, on the hinge side Tom meshad 58 and a quata!! Watchin Tom wurk is a Wicked pissah!
fuggetaboutit
Thank you so much!
Thank you!
If you're on concrete slab you might want to put a shim under both sides to keep the door off the concrete.
Tile was to be installed.
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.
Yep
Yup, then you`re coming back in 1 year to rehang every door after it has settled, lol
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.
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.
@@billy9043 adjustable square set to 1/4 inch trace inside of pre-hung jamb on both sides of door. I dont condone pre-trimming any door but anything is doable
Nice work! Theres no school like the old school
Remodeling a house. Should I install doors before hard surface flooring? Just leave a space at the bottom of each jam? Or...flooring first?
I want to know what countersunk drill bits he's got, those look nifty
It's a tapered countersink bit, designed for wood screws.
Tom makes awesome video. Great teacher.
Justin is from Jordan Schlansky’s home planet.
Thanks for sharing Tom
Nice video,Good instalation.home owner should under pin foundation(slope in floor is worrying )😊
Why did you measure from the bottom of the door on the hinge side, but measured on the bottom of the jamb on the other side?
Homeowner: wow that's gonna take some work
Tom: Oh yeah
Reality: Takes Tom about 3 minutes lol
And homeowner didnt lift a finger
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?
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.
And likely he took those shims out after the striker side was screwed so tile could be later later.
If you guys look for good windows around US or Canada, I suggest looking into Dako products.
The slow methodical discussion is perfect for learning this. I bet someone sits next to him and says slow the f* down... Over and over.
Lucky guy had no idea the wealth of knowledge that was in his house!
So he hooks the bottom of the door adds 7/16 of an inch to the 58 1/4 to give a 7/16 gap under the door right?
Where do you mark the jam to cut it with the circular saw?
"It came out really good I love it"
Made this look sooo easy, but I know for a fact that I’m going to F this up lol
He didn't have to cut the frame down. Had a lot of space above the door. Now he will have to under cut the door when he does the tile.
