Sagging Floorboard Repair | No Damage To Floorboards 

Awesomeness!!! I looked thru many videos before I found YOU!!! This helps my floor guy repair what he did 2yrs ago. THANKS TO YOU, it is easier than he thought! You are a life saver!

Spent a few minutes looking for this solution, thank you for taking the time to share and educate the rest of us ;)

Keep the drilled floor dust to put back in the top of the glue so it matches the floor.

Thank you for sharing! I saw so many videos where people used the window foamy stuff and it makes sense not to use that with how flexible it is. I'm going to try this.

thank you, it's midnight and I have to fix my floor tomorrow and you just saved me a ton of time and a big expense of tearing up my bran new floor. Keep the videos coming!!!

I was skeptical at first, but wow that was amazing. Great job!!!

I was looking for a solution and there is no videos on youtube for sagging floor. Yours is the only one I found. Thank god I don't have to replace the floor. Thanks so much for sharing this video!!

Finally a video that shows how to fix this!!

Best solution video ive found for this problem. Thanks

Gonna hive this a try to my worsening floor laminates. Glad I found your video. Thanks, Bud👍

This is EXACTLY what I needed! Thanks!

Have exactly this going on atm - many thanks and greetings from England,!

I have exactly the same problem. Laminate laid over a small repair patch of concrete. Now I realize why the piece is sagging. The rest of the floor sits very nicely over the old concrete. I think I have the skill to fix this, thanks to your fine ideas.

You've just help me out sooo much, thank you 👍

Great advice, you’ve hopefully saved me time and money. 👍

Great video! So helpful!

Genius! Love the video

Awesome I can’t wait to go get my supplies !!!

You are a genius, thanks for the vid yo

Excellent video. Cheaper that lifting the floor.

Nice video, great results. I used Shalex stick it pro on my floor.

Hi just found your video and hallelujah 🙏🏼. Was planning to go the expanding foam route but your method actually makes much more sense and my situation is identical but even more of a drop between the boards. Out of interest what tile adhesive did you use? The reason I ask is some adhesives are quite thick and I presume struggle to be pushed through via a syringe? It looked like a Mapei product but not sure? Many thanks and a great vid 👍

Appreciate for making this video! QQ: I see you kept injecting the adhesive several times into the same hole, so how did you determine when to add more or stop adding? Does the adhesive actually find its way self level to other hallow spots?

Now that few years past, how was the outcome of the adhesive? Did it get rid of the problem?

Like you I could not find a fix for this issue so thank you 😊

Thank you! It was very helpful

Wow well done interesting approach

Very helpful. We have a sagging area in the pantry/laundry room that drives me nuts. We will give this method a shot.

Handy tip. Thanks

What kind of adhesive did you use and will this work on floating planks?

Ted Would it be the same fix if the floor is a oak floor over cement The entrance from garage to house

Thank you for the simple and great fix! I am going to try this out! Really appreciate coming up with this. Did you think watering down the premix would help or be okay?

Very nice video, I have the same problem, uneven suspended subfloor. Is there a reason for using tile adhesive? I am worried with time it will crack and make a noise as you step on it. Thanks.

I have a sagging vinyl plank in the center near the edge. Currently the floor plank next to it is removed because I was in the process of replacing it. Can I apply the tile adhesive under the plank since it’s exposed? Is there any expansion with the tile adhesive or does it spread and dry as is? Thank you.

Thanks, quite helpful

Thank you so much for this

Great job.

Nice video ! I had a thought get a marker the color of your floor and touch those spots where the holes are with it and the little white circles will blend right in .

How small of a drill bit did you use for the holes, and was there a reason you put the holes in the sides of the plank and not the middle of the plank?

Is there any reason why you drill the holes at the edge of line? Is it okay to drill kinda center?

Is there a different adhesive you would suggest for a hardwood floor panel? Or should Mapei Type 1 still work?

Another great video, if you can could would you put product links for the tools you use such as the suction puller, thanks

Very helpful video. How do you know how much tile adhesive to inject?

Wow, this is exactly what I'm trying to fix. I did not want to remove floorboards and have to memorize all the flooring pieces and their locations for reassembling. I'm going to try this fix this coming weekend. Just out of curiosity, what size drill bit did you use ? Thanks for posting this !

Two questions: Can you use this technique on floating floor laminate(non grout )) ? Also can you use glue instead of tile adhesive? I did this in the past but I used wood glue and drilled in the center of the laminate tile. I had to fill in with wood filler to mask hole, but drilling on side would hide holes well so glue will move towards gap if you have suction cup.. I have a glue with Elmer's/wood glue consistency that I can use with caulk gun that should be easier to apply and dry like hard plastic

Thank you for the helpful video. Quick question: Is there a way to screw this up such that it would make things more difficult for subflooring experts to fix? Trying to avoid needing to get their help with solutions like this, but want to make sure there's little risk for somebody who isn't generally very handy.

will this work if there foam underlay under laminite floor

Is there a link to your adhesive

Great video, do you think I can use caulk as a filler?

Thank god I found this! Quick question though, how hard is that stuff to remove when I want to eventually change my flooring?

Now that it has been a while. Did it work?

Whaow that's awesome.

I can’t believe there is a solution for this without taking the floor out !! THank you for sharing ! Question, how long does the adhesive take to dry up? I’m going to give it a shot soon.

I have the same problem but underneath my floor we have soft insolation because the cold weather,do you think this will work???

This is the fix I was looking for! Do you think I can use PL glue instead of a tile adhesive?

This is EXACTLY the solution I needed to fix sagging gaps under my old tongue-and-groove floorboards! I will modify the technique slightly, since my floors are made of real solid wood instead of vinyl/laminate. But the essential piece I needed was to know WHAT to use to fill in underneath. I had already thought about drilling holes like you did, but I couldn't think of a good product to actually use as the filler, that wouldn't squish underfoot, but wouldn't crack and crumble either. I also needed to see someone else using the drill-and-fill technique, to give me confidence that it's not too outlandish of a solution and could actually work! How would you say this floor is holding up now after some use? Thanks again for sharing this video!! Extremely helpful, and very well-explained and demonstrated!

How did the holes look after you touched them up with the pencil?

Is that glue & if so what’s the name of it

Can I use the Alex paintable caulk? I used it to caulk around the window and even though it is flexible, it is semi rigid.

What size syringe is that?

That's a good presentation simple and effective. Tile adhesive is glue or cement? I would have try to use a plastic lever like a wedge Why the two holes? Air comes out easy no second one is required.

Hello What is the filling called

I spent hours searching for the solution how to do the exactly same repair without removing entire floor! Thank you! Very helpful. One small question please… are you using flexi floor tile adhesive or any tile adhesive will do? Thank you in advance .

I am so disappointed having got my floors done by a contractor, only to see few areas with a similar problem. This contractor will never put foot in my house again. Thanks for the video. 👌

Do you think Fix-it-All might work instead of the tile adhesive you used?

Good video but isn’t that a floating floor? And wouldn’t the tile grout harden to the point it wouldn’t allow the planks to adjust with change of season causing a bigger problem? I’m very new to home repair since I purchased my first home so I may be very wrong advice is much welcomed

Can this method work on vinyl plank? Thanks!

Nice approach. but it seems may brake laminate ability to "float". Would not laminate adhere to underlayment?

I have this situation on like 25 boards, maybe more. What is the best solution? Remove all boards and see how to concrete is? If its a poor job, then its a hidden mistake and i could ask money for repairs?

Nice. But it gonna leave holes on the floor. what you gonna do to hide those ?

How did you cover up the Holes you drilled ?

How long did it take for the adhesive to dry before you could walk on it?

Do you inject it below the underlay or between the underlay and floating floor?

Hola vale para eliminar un chirrido

under the laminate floor dont you have a white sheet of polyfoam?Ita direct on cement?

Will this work on click lock flooring?

How do you fix the holes you drilled into the floor?

Does it work on concrete subfloor?

How has this held up since you fixed it?

Could you make a video about water damage laminate flooring how to fix please?

How long does it take for it to dry

My LVP is in a basement on top of cement, and the installer put the floor in without using a self leveler in the spots that are clearly flexing up and down. I wonder if you could use thinset vs the mastic? Do you think it would pass thru the syringe the same?

how did you use the tape? :/

I can't get the suction cup to stick to the floor

If it sticks to the floor and the wood then the floor won't float

What is your opinion of the "Fix-A-Floor" product?

Whwre can i order tool for needle

Do. Inject the tile cement beneath the floor underlay

I will be using LePage NoMoreNails floor glue

That's a broken tongue, every you tube video I see sends chills up my spine. I've installed floors foe 21 yrs, my family for 46 yrs. People are so misled with videos showing them how to install the floor but not how to properly prep a floor for installation, or the fact that if you don't prep your floor right you automatically void the warranty on the floor. If this stuff decide to bond this floor will pop or separate around eventually

Lol. Do you live in Florida? And can you come over and fix mine?😊

Good Idea.But don't the floor are suppose to be able to move? And if you put that stuff that piece is gonna be glue in the plywood

Can you come to my house and fix my laminate floor? (I have that exact same problem).... lol Original installers just kept cramming more adhesive in, but it never solved the problem...

You should have drilled in the actual plank not in the seam and then you can use the little plastic shavings that are left over from when you drilled and you can melt them with a sottering gun back into the hole. There's actually videos on how to do that and you can't even tell because now you're gonna see the hole in your seams

Good, now give us solution to fix the world hunger and world poverty

It's sad that nobody contacts the contractor about a hack job....then turn to doing another hack job to fix it.... obviously you need to make sure you're subflooring is level to each panel... it's not necessary to be level to the world... just less wavy....

You didn't say how well it worked.

youre video tytle sais no damage to floorboards not minimal damage, but NO damage, How can you say that if youre drilling through ? you have no shame man

Nice bro
