How to repair or replace a damaged section of subfloor.

A common problem with replacing subfloor is how to provide adequate support of the newly formed and installed flooring edges. I show the entire process from lay out and demolition to installing new flooring structures, 'blocking' and the new sub-flooring ready for carpet.

Here are some related product recommendations.

Finally someone that knows how to fix a floor proper, been through a lot of videos, some ignoring the problem and just spray painting, some cutting and replacing with no added support, this guy gets it, he doesn’t want to have to fix it again.

About to rip up old carpet and padding and do exactly what you are doing in this video to repair floor damage, appreciate the step by step information. I'm dreading the job but hopefully this will make things a little easier.

Good job and great demonstration. I have a soft spot in kitchen and this really showed me what to expect and gave me hope that it's not as bad of a situation as i was thinking. Thank you.

Thanks for the video! I have to repair the floors in the mobile we just inherited. I hadn't thought about boxes!

[rogerwohlgemuth]

The box idea is great. I would have added blocking but this is easier and adds structure to the repair.

Thanks for this video, it really helped me. I had to make this repair and I admit it took me most of the day between removing the damage, installing the box, picking up material and laying the plywood. I'm pretty handy but certainly not a pro. I would rate this degree of difficulty a 7 out of 10.

Thank you for posting this vid. Whoever decided my manufactured home needed a furnace vent in the middle of the kitchen floor didn't cook much (it's a crumb catcher). I was worried about edge support for the patch, and your 'box' idea is brilliant. I may put rosin paper between the flooring and patch to ensure they don't squeak.

Nice job. I just bought a large manufactured home with some compromised particle board subflooring from lack of a vapor barrier in a humid climate. Your video is very helpful and I will be making some boxes! I'll only replace what is needed, then install a vapor barrier and crawlspace fan.

Thank you! The guys who I thought of hiring were only going to replace the plywood, which seemed wrong to me. so glad I saw this video. I'll just do it myself

Very clever and practical problem solving, Alexander.  Thanks very much for making this video - it helped me A LOT!

Thank you. I am replacing carpet and found plywood edges not connected to the floor joists. NOW I know to build a set of boxes for them. Thank you, also, for showing that mistakes happen. ;)

You guys are awesome 👌 👏 😎 after watching your videos 📹 it makes me feel more confident about doing it. I have a bad floor in my bedroom. It's a 1970s single wide trailer. I been needing it done for awhile 😩 now! But I've never layed flooring before. But I feel now I can do it myself!

i have a 4 by 4 foot area to replace for carpet install and you really clarified a great deal for me again, thanks

[alextupou]

nice work! I like the box idea, its a strong fix and provides plenty of support for the new floor. will do this on my next project floor.

[BlueRidgeJ]

That is now the strongest part of that mobile home!  Good repair.

This video helped me tremendously! First project on my own, restoring a Layton 1964. Thank you for ur help!!

[JillNelsonStrongdiva]

Great video. I am a newbie home improver and followed your video step by step, even starting and stopping it as I worked. Thank you so

Just bought a termite eaten mobile home. The termites are gone, but the floor needs to come up and the walls off. I want everything new. This video made it easy....going to buy two other homes: one in Costa Rica, one in Rep. de Panama. My termite eaten home was so cheap, I can live there for free and have two other places to live.

What a great how- to video! Thanks for making it. I had my husband watch this. We have both been putting off such a repair job as that in our home. We bought a home not realizing the damage under the floor covering in front of the kitchen sink. With your video we have a little more confidence going into the unknown. Thank you, thank you, thank you. Excellent job!
