Subfloor repair. Floor joist mistake.

It is a very common thing happen when one side of subfloor panel was unsupported by a joist. The plywood was free to flex and squeak every time someone walked by. Not good in a hallways or high-traffic area. At this video I would like to show how to fix this problem. Thank you for watching my videos.

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

[@EFRSeattle]

if u have left and right hands its not a problem. Good luck!

[@laurenrobinson7328]

@TheRageMaker No question is a stupid one as long as it's genuine. Maybe they don't have much experience with powertools and aren't comfortable.

[@MarkARebuck]

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!

[@j.gardner7740]

Mark, that was actually my favorite part and I even watched that part again because I thought it was so cleaver.

[@SokaDeb]

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.

[@EFRSeattle]

Thank you.

[@chrissmay2482]

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.

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

[@PietroShitzberg]

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?

[@jaydenb7515]

Prob would be better cause it’s relying on the 3 screws to not break off or rip itself through floor

[@stevelopez372]

@@jaydenb7515 This works fine with 3/4 plywood almost no flex in short section. Would not work well with osb though.

[@kevinphanson]

@@stevelopez372 "almost no flex"... and there's the problem. there's should be NO flex. the weight should be supported completely by joists. This may seem like a fix, but over time, that support WILL fail.

I agree with A C.....

[@justinballard7242]

He should of went back 16 inch's to the next joist

[@williamcrowley5506]

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

[@donlucas3462]

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

[@kalijasin]

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

[@dildoshwaggins1780]

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.

[@stevelopez372]

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

[@Beethovenfan12]

Only one side of the replaced piece is actually attached to a joist, though. It is a pretty small area, however, so maybe it will be strong enough.

[@stevelopez372]

Mud Marine yup, seen it before, 3/4 inch ply is part of the reason and small area , OSB wouldn’t do in my mind.

[@TheMargo420]

Perfect. Thank you.

[@ross5506]

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

[@robertbamford8266]

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.

[@joedarden2276]

Well Done

[@David-yh5po]

Thanks for sharing this video with us.

[@TheBBBB0B]

Good touch with the glue.

[@stephen_b6069]

This is a great repair ideal but instead of doing the second 2x4 like he did if at all possible just cut the plywood square a little larger to the next joist and attach to it or sister it there like he did the first block will make for a much more stable repair

[@ChicagoBirdGirl]

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.

[@proudconservative3676]

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 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.

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

[@stevelopez372]

It works with 3/4 plywood which is very stiff in short sections not so good if it was osb.

[@chrisortiz8072]

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

[@michaelwilliams4768]

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

[@timavery7984]

Derrr

[@TheNewenglandboys]

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.

[@jeromegarcia5396]

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....

@@CidZAER I had seen a video on youtube where it was expressed that gluing and screwing a subfloor are improper from a structural perspective.
