Subfloor repair. Floor joist mistake. 

I need to do this to my mom's house how difficult is it to do not knowing much ?

I like the technique of using screws partially-in to hold stuff up. I have been renovating a bathroom, and could have used that technique twice this week. Thanks for the video!

Very simple and elegant solution. Thank you for sharing this!

If I ever need to fix a flexing floor again I am definitely going to use this technique. Thanks for sharing, EFRSeattle.

This is an outstanding video. I learned so much from this! Excellent tip using the pry bar to tighten the brace against the subfloor. Thank you.

Well Done

Thank you for this video. We had a even larger hole to repair and this video in particular was a huge help to us and our hole is now repaired solidly. Thank you again.

Same technique I use for filling old heat register holes. Like the screw and prybar trick. Thanks for the video.

Perfect. Thank you.

I don’t get it. Yes one piece has been sistered with an existing joist but then the other piece is screwed to the floor but it’s effectively got fresh air underneath it. Would it not have been better to find the next joist along and get everything connected to those?

great repair,the only thing i would have done different was used 5 or 6 screws instead of only 3,for more solid repair

Thanks for sharing this video with us.

This is better than buying 1 or 2 sheets of plywood and putting in new sub flooring.

Guess it would of been much easier with unfinished basement. Very nice work.

Awesome video!! Thanks for the tip! 😎

can you help me. i tried this but the carpet stuck in the saw and the blade pulled a huge strip of carpet all the way down the hallway. so i guess my first problems i need help with is how do i get the carpet out of the saw while its still on. and my second problem is how can i put the carpet back down and make it look like i didnt touch it. please reply, my dad gets home in an hour.

Good job solid blocking and fastening, polka music no so good.

Nice tricks!!

Good touch with the glue.

Nice!!! Work...

Excellent. You can also do it when there is no joist on either long side. (Added inset register covers.). One suggestion: I used Titebond III on the surfaces of the horizontal pieces where they attached to the underside of the subfloor.

Came here to get tips, stayed for the music 🧜🏽‍♂️

Very good work. #1!

Nice job

nice job bro.

nice job

Genius ...

Thanks for the video! The music makes me feel like I'm watching an early 90's European soft porn movie. :) Seriously though that was a neat trick holding the board in place with the bar.

I aside from an interesting video, your music selection was perfect!

At the end, He had to pet it like a good floor. Good floor wants a treat??

If you cut into the joint about a 1/4 inch will it cause issues later on? My floor has some swollen edges that creak. I worried about cuting into the joist since i dont know how thick the original boards are

​ @EFRSeattle Should you caulk all of the floorboards when patching up subfloor?

It's a very informative video but the music feels like a bad hangover.

Really it’s a video showing you how to hide your drugs

Not to criticize but a few more inches over and you could've installed some solid blocking between the floor joists. Then the edge of the subfloor would been solid. This method is fine for a while but it'll loosen up in the future. Just sayin.

How do you do this with i joists?

How would you be able to do this if you have I-joists?

Great soundtrack

The builder was pretty bad laying the 4x8 sheets. First no support in that area then one long running seam that should be staggered for strength. Where was the inspector? BTW nice job.

I'd rather hear you talkin about the job while you're doing it then listen to this terrible music

Would of been better to go to the next floor joist instead of the middle of the bay and block all the way around....Not the best repair in my opinion

Why do people think that adding music in the background is a good idea ? I appreciate you trying to help folks out here with their floors however, it is upsetting that you must think that everyone will like your taste in music. It’s your world we just live in it. Kind of reminds me when I was sharing a cubicle with someone at work and the guy I shared a cubicle with, would play music. I did not like it because I was not given a choice whether I wanted to hear the music or not. I kept the sound off while watching your video. Overall thanks for making the video.

We have this problem with our floors.

So what's 2x4 supporting on basically screwed to subloor

I would of just made a box and installed it to joist at least one side if not two sides.

pro tip; mute the video, your ears will thank you

Was the scarface themed music really necessary instead of just explaining what you are doing?

4:03 - I don't understand. The second 2x4 doesn't appear to be attached to a joist so I don't see how that provides any support at all.

Why put a screw in the plywood if you were going to just push it down

Good video but an absolutely awful choice in music which is pulsing in and out and does your head in please remove the music or put something decent on that does not do your head in

Crawl space FUCK!

Derrr

I would prefer verbal explanations to that HORRIBLE music?!?!?

Couldnt watch it that constant drumming music just didnt cut it with me.

Wrong on the 2x4 being held by screws to subflooring... you cut stud to stud like a real man, don't do this if you about doing it right... joist to joist or not at all....

This video is not very helpful without explanations on what you are doing and why.

I don't think you are supposed to be gluing and screwing subfloor...it's more likely a no no.

So there is only one edge of that piece of plywood that is going to be solid. Obviously the side that was sistered to the joist. What good does it do to screw a piece of 2X to the floor? There is nothing supporting it! That outta be fun fixing that after all the liquid nail around it. Sorry but this method is useless. Should have cut back to the joist on the other side and sistered it also.

Need to replace whole floor

Well Done
