Here's a tip - rather than tacking it all down, tack it once and leave it a bit loose. Then, when you're installing the second board you will have wiggle room to adjust it, rather than having to adjust your saw and make additional cuts. Once both boards fit, tack the first one fully and move on to the next board leaving the second one a bit loose, and so forth.
Trims should be aligned with the frame. In a perfectly made frame you won't have to readjust the saw, because all angles would be 45 degrees. In reality, frames are not always perfect, so you have to adjust the angle if you want to get a precise fit
@@val4803if you build the jamb and attach the casing before you even attach anything to the wall, you get best results, and can do more windows faster. Just make sure your jamb length is proper
This video was a lifesaver! I've struggled with putting window and door casing for DIY projects for a long time. The 3/16" marks with the square was the best! Followed that trick and it worked out perfectly. Thanks.
I watched 5 of they and this one is the best. I just did my entire home using this method and job came out great.
Love this video! Years of experience packed into 3 minutes. Thank you so much.
I agree with Buddy. I've watch several of these vids for putting trim around windows. I have an older house and the basement windows are not square. I think the method outlined in this vid is going to be my best bet!
It took a while to find this video. It is great. I followed it to trim 2 windows this morning. The process was easy to follow and the results were great.
Thanks for making and sharing this video.
Watched this video just a handful of times and slowly but surely, I was able to put together a beautiful window in several hours. The initial cuts are relatively simple, and if you take your time and ensure that the final cut is perfect, you'll have yourself a glorious lil' window when you're done! I'm sure the next one won't take as long, I'm just meticulous.
Found this gem. As soon as I buy some brad nails this week I’m so doing this. Perfect tutorial. Thank you 😊
Thanks for your help for us neewbies. Can I add after doing it a second time we found it immensley helpful to put a level on the first piece before nailing, and on each of the others. It made the other cuts easier and tighter.
This was a very good tutorial. I followed along and my trim is just about perfect.
Thanks for making this video, it really helped me- such clear explanations are helpful for newbies like me. I just used nails and it went well.
Best advice I’ve seen yet
Great video. Really explains proper method to install trim
Setting your miter saw to a back cut of 1-2 degrees makes sure your 45 degree cuts are nice and tight. You do have to change the way you cut your angles though, always being aware of the way the blade is tilted. Once you've caught onto it, it makes your miters perfect.
This method worked like a charm for me.
very informative and easy to follow. Makes it look so easy.
Beautiful!
Oh, my head.
But you teach and work so well !
Thank you for sharing
Thank you so much 😃
This guy knows his stuff! A+++++
Pro tip: Report SPAM.
Well done. Thanks
Thank you buddy. I forgot after a few months.
Very helpful
This is awesome.
very cool tip thanks.
this was so helpful ‼️🙏
Well first time doing this and it turned out awesome because of your easy instructions thanks so much 🛠 keep up the great videos 🛠
Thank you!
thanks! Awesome!
Thank you
Awesome video. I had never really done this before and my miters came out perfect. My house is old and the framing surrounding the window iwas not perfectly square. That is why the 45 degree comment below may not be relevant for every scenario. Mine were definitley not all 45 degrees and if you forced them to that the reveals would look off.
Great video! This is one of my weakest skill set. Your video may help me correct some of that-thank you!
Good job well done !
Thanks. I was hesitant to start but your video helped a lot. Another tip, make sure the chop saw blade is square with the base (mine was off a bit). Thanks again. @RandyMan626
Good info thx
I'll try that
Drinking game every time he says mitre
This is the correct way. But I would nail the top and side pieces on the jamb. Then Nail the top corners to the wall so they stay nice and flush.
The bottom piece is easy.
You could just cut it to the same length as the top one, but in this case just make sure the jambs are pointing 90° put the trim upside down against the 45° corners of the side trim and mark the trim Yu need to cut. Go to the miter saw and cut the pieces 45° inwards and you are done.
The piece should now fit snug and flush against the side pieces. And because the side trim is not nailed to the wall you do have a few degrees of play on either side to press it against the miters.
If you end up with a tiny gap, just fill it with paint and wipe with paper. To hide it, fill the nailheads while you're at it. 😊
Always remember...you can cut more off, but you can't put it back on. These tips make sense, about to get to work on it
Nice
Awesome step by step info, as well as tips! Nicely done. Do you have a video on doing trim for doors? Thanks.

How do you remove the slight lip (overhang) around the inside edge? Why is it done this way?
Good, simple process, but I'd only change one thing... pin the frame first (inside & corner 1" pins), then return to nail the outside (2-1/4" brads). That way, you don't have to keep switching gun nails... unless you have two guns to use.
I used to nail the side verticle pieces in the middle only. The I slip the top or bottom horizontal piece under the sides and use a box knife to mark the angles. I then deepen the cut and score a second knife cut 45°. This makes a channel in the wood to place your saw blade. This gives perfect fit and exact spot to start your saw cut first shot. I used a knife for marking and do fitting, rarely use a tape. Retired now after 40+ years
awesome thanks 4 the tip😊🙏
@@carolinewells4355 You're welcome.
A miter protractor (angle finder) is an inexpensive tool that takes a lot of the guess work out of these cuts.
I like the style of trim. What is it called and where can you get it?
Great video. One question: typical legth of one piece of casing is 96 inches. I need about 100. Are there longer pieces or i just combine 2 pieces together?
I would combine 2 pieces. Also remember to join them by cutting them at 22.5 degrees and not 45 degrees.
Great window !
But what do I do if I have a certain time period to finish a large amount of windows, each window will take forever.
Will this apply to vinyl windows with trim? My house was built without trim package I just have the stool and apron everything else was finished drywall
Great video, thanks. But I hit both sides of every joint with glue.
Would it be easier to just pre make the window frame casing then put it on ? Or would that not work.
Quick question for everyone. Are through traditional interior window sills still popular, or are people just trimming around the bottom/stool like on the other sides.
What gage were the brad nails?
The jams in my new windows are plastic or vinyl. Is that that case with the windows in the video? I don't want to send a nail in vinyl or plastic if I'm not supposed to.
"we don't need a measuring tape"
Also "you may have to cut 3 or 4 times to get it to fit right"
This is the epitome of measure once cut twice
Would this look totally ridiculous with for a window with a window sill? If so, how could I frame around that to make it look good? Any tips very much appreciated!
Let me make it clear.. the window sill has a marble ledge that sticks out past the wall
Only wish my windows were square for an even reveal
Any recommendation on what type of miter saw and size blade should I purchase to do a window trim? This will be my first time doing saw
Home depot sells a ryobi 7 and 1/4 miter saw for 130 dll, this one will work fine for window casing as long as the piece is not to big, but there is tricks around that, this saw comes with a blade already but I highly recommend buying a diablo ultra finish blade
I would buy a 12 inch single bevel miter saw if I were u. I made the mistake in buying a 10 and quickly outgrew it (within 6 months). If I could go back in time I would have spent the extra cash for a 12 in slider with double bevel. If all Ur looking for is to cut 2x4’s and 4x4’s a 10 in saw works fine but the moment u go to a 2x6 u will need a 12. As the gentlemen said earlier buy a diablo 40 tooth blade. There top notch, U could even cut window trims with a 24 tooth framing blade if the casing design is simple. The more complex the trim then u will need a higher tooth blade which will give u less tear out. Hope that helps
What type of design trim is this?
How do you do the sill?
How do you install them on concrete walls let me know thanks
where did you buy window borders?
Sir great video, quick question, why do I need to have a space between window and wood trim, aka reveal, or do I need one , or can I just install window flush with windows, thks
You don't need one per se, but no board is 100% straight, so lining them up even can show any variations along the edge much more easily than leaving a small reveal. It also adds slightly more detail to the trim than just putting the trim flush.
The reason is it adds dimension and makes it more interesting.
What size wood trim is that?
Is glue really necessary if your using nails anyway? How does that help?
I like to cut the bottom and fit the sides in that order. Then cut the top a little long. I drop the top on and even it on both sides. Now I can easily determine if miter angles need to be adjusted on each side without the need to hold it in place while checking. (Doors too.)
The video didn't mention what gauge brads to use. My 18ga. brad nailer only goes up to 1.25" but my 16ga. finish nailer goes 1"-2.5". So I could go with 1" 18ga. brads and 2.25" 16ga. finish or go with 16ga. finish for both. Or does gauge not even matter??
16 is overkill for window casing, it may split the wood in some cases but not all the time. Worse part is u have bigger nail heads to cover up if all goes well. I would get an 18 gauge that handles between 5/8-2-1/4
What gage were the brad nails
What type of blade to you have in your miter saw? Looks like at least a 60 tooth?
Our editors recommend a 60 to 80 tooth blade for a 12" miter saw. If you are shopping for a 10" blade, make sure it is intended for a miter saw. Blades not meant for cross cutting (such as table saw blades) may not give you as nice of a cut even at higher tooth counts.
Buy as many teeth on the bladr as you can afford!!1 I run a 96 tooth on the 12" miter, cuts fast and virtually no chipping.
Great if your on the first floor , not fun if you are on 2nd floor and saw is outside
Good point 😂
What kinda tool is that used to mark the 3/16" in each corner? (what's the name of it?)
Does anyone Know?
Here in Canada it's called a t square. I've heard it referred to differently in videos from the states.
Why didn't I watch these videos before I cut and painted all the trim...
...mmm it seems odd that the window was out of square ! are you sure that your miter saws degree gauge is set correctly ?
I wish he explained the adjustment measure and cut
How do you hide the nails? They are obvious on the trim
Small about of filler. Then light sand and paint.
It’s very easy.
Filler and paint
Fill>Sand>Paint
With painter’s putty
That is what they mean when they say working smarter.
No leveling?
Geez. Just grab a measuring tape.
These kind of mitres should be 45 degrees
End of.
I don't know where you learned anything. All miters should be 45 degrees. You put up you top piece of trim and had no idea if it was level. Level is level, plumb is plumb and square is square. Once you made your top piece you should have made and exact sized bottom piece same with the sides one you know their length. Then it is a matter of making a rectangle with square sides. I need to shut up but seriously you are giving bad advise.
No. Not every window will be perfectly square. His instruction is sound.
Square or rectangle they are close enough that any reveal is not as noticeable as an unmatched miter. Every time you change the angle you change the length of the cut.
Husker GunGuy I'm assuming this video is for the diy who lives in an 1890s home where nothing is plumb level or square, and they simply just want to retrim their house or the replacement window they just installed. This seems like a nice tutorial for the diy in those particular situations. There's alot of homes that fit that description. Maybe I'm wrong but I don't believe he offered this as perfect free mason expert adivce.
Maybe a better tutorial would be on proper use of equipment. Proper saws and saw blades for perfect cuts. Something I'm only just beginning to learn. Can't just use any Ole miter saw blade. I've fallen into that category of typical diy'er. I see all the mistakes I've made now.
yes you do need to shut the fuck up as with any install you have to compensate for field conditions, so if the wall or window is not strait level and plumb then the method he described is the best solution, you way is good for perfect conditions.
His method is right on. You could have a 10 year old house that has windows that are not perfect. That 10 year old home could have windows that were installed by a bad contractor (and there are plenty of those out there) with trim that was installed by someone whose motto is "close enough" and you decided to upgrade the trim. If you cut all your joints to a 45 degree angle, when you're done your window won't look right because you surely will have gaps all over the place that you'll end up filling with caulk and paint, and reveals that will most likely be all over the place; remember the creed of bad contractors, "Caulk and paint, make it what it a'int". Remember, no one will ever see an angle that has been tweaked because the fit will appear perfect, but everyone WILL see bad joints with gaps and caulk forever! Would you really want your windows trimmed by someone who thinks like Husker Gun Guy? The smart ones will do it exactly like he does in his video.
