How To Repair Sub Floor In A Trailer House or Mobile Home 

Thank you! Great video! Been waiting for boyfriend to fix my floor in my mobile home for over a year! Thanks to your video, I fixed the hole my damn self! Thank you so much!

Another method is, you make a square frame from the 2x4s then nail it to the floor joists

I have the exact same problem in my mobile home , you get right to it , no BS…appreciate the advice, liked and subscribed..keep It up!

You just helped me grow some balls. Thanks, bro 🤙

Great Help Thanks. I had to replace floor in Two rooms in my Mobile Home with Six 8Ft X 4Ft Plywood Boards due to AC Vent problem you describe

Thanks, we’re about to do our home.

I have replaced my bathroom floor in my house 3x since 2018. As soon as you said metal ductwork and hole I ran and checked. Yup I have a hole so hopefully this will be my last time fixing it.

Pop a hole so you can measure from joist to joist, measure from joist to joist, mark the edge of each joist, cut a piece of plywood to fit, mark edges of your piece lined up on your marks, cut marked edges, cut 2x4s for side blocking half on old half on new, cut 2x4s for blocking to existing joists, screw 2x4s in, screw plywood to 2x's. You should always put blocking in from joist to joist never just from old plywood to new plywood. It doesnt seem good to screw through the old mobile home floors, just let it sit on the blocking or use glue When you encounter glue on the joists cut a bunch of lines with sawzall or skillsaw like an inch or two apart, and it chips out easier

I replaced the subfloor in my friends trailer. Turned out good. Pulled the carpet back replaced with plywood and recovered the carpet. She was very happy

Thank you for showing this. I’m a single mother of 3 boys and I’m trying to fix my mobile home floor. I will let you know how it goes. Thank you again

Yeah I'm doing my bathroom in my 2003 double wide..I have a few friends helping me...

I worked in construction for 34 years until i really messed up my lower back but i can teach others how to do things

Very good video. You did a through job of explaining about what caused the damage and how to repair it. GOD BLESS Y'ALL.

Very informative video. Am having problem with spongy bathroom floor. Not sure if it is shower drain leakage, hot water tank, toilet, or possibly AC duct. That is something I hadn't even considered. Now at least I have a good idea of what would be involved in repairing it.

Whoa. We use a block between joists when at edges. This method is for boo boos or under a cabinet. Stay safe. Thank you.

Made it look easy. The hard part is getting everything out of the way to get at the problem. (Furnature, toys, carpet, pets, people...) Good idea on the side "wings" to control flexing.

Why replace it with that same damn glue board that gives you all the damn problems? Use plywood and be done with it.

We just had a really long cold freeze in Indiana. Our pipes froze under our mobile home. When we finally heated them up, cracks and sewer line froze,backing up into the tubs. Clean water backed onto bathroom floors.Ran into bedrooms. Your no nonsense application to the problem filled my heart and hopes. I love the way you let your son help and learn. Great

I was hoping this would help me. My floor issue is where the fridge goes so I’m going to want better bracing. Our home is getting quite old so this method will probably be put into use soon. I’ll use plywood rather than the OSB though. I want this to last longer than me. I hope. Thanks for sharing this. Made it sound so easy!

Thank you for the video! I had unfortunately watched 5 different videos that were a complete joke before finding this video. This is by far the best video and all other videos should be removed from the platform. Good stuff I'll definitely looking forward to any future videos you put out no matter the subject of the video!

You should've fastened those short 2 x 4 side pieces for better support. Honestly, I don't think you'd even need them to begin with. But. Hey, it's your house!

Thx for this. I think I have to call someone for help here. I wonder how they would do it. Then I know and can’t get ripped off. It’s more fixable than I thought.

Nice to see your son learning and helping. I learned a few things from my dad and I’m happy he did.

Kudos for using a knee pad; your 80 year old self will thank you.

Wow. Great video! Super helpful. THANK YOU!

Getting ready to start repairing several sub floor spots and this was so helpful. Thank you!!

It does help me, thank you

How do spots near the wall? I really dont know where to brace it at w/o screwing through the wall. I think my window leaks.

Great video, is helping me take the fear out of tackling the job 👍🏼

Why not use a full length piece betWeen the joist that would be much stronger than the two peice you using here

Very informative video Tobin 👍 Great job on the sub floor. Thanks for taking the time to show how it's done. Have a great weekend Love 🌻 from Apex NC 💜

When you pull the old up, put cross blocking in. World of difference.

I’m replacing a subfloor in a pier & beam. Would it be worth it to seal OSB with a coat of polyacrylic on all sides? Anyone have experience with this hack?

Thanks! Very helpful! Direct and to the point.

Just what I needed! Buy a mobile with some land… needs a lot of work. I’m doing 2” of closed cell SF once done. No more moisture problems.

Whats the thickness board you use to patch

What board did you use 3/4 or 1/2 thick

Thanks, i knew my floors felt damp for some reason. Makes sense when you said the ducts leak. Sending moisture. Thank you. Gotta get new floors new duct work.

My slumlord hired some drugged out handyman to replace the subfloor in our kitchen and it's already stating to give again. Thanks for the video.

Thanks For Your Common Sense Instructions! Looking At An Older Mobile Home Needs Extensive Work This Helps A Lot Thank You!

Thank you for your video. We need to replace all our subfloors in our older mobile home, here in western nc. Hopefully we'll be able to come up with the funds for that.... We did the part of the kitchen ourselves a few years ago. You're right about the dust!!!! Moisture is the enemy. And we seem to get so much rain the last few years! Thanks again for the video. Enjoy your day! 🌻

Im about to fix a mobile homr that has about 10 soft spots. a few are by the a.c as you spoke of. I understand what u did and why u did good, but Do i need osb or plywood?? Also was urs 3/4 or 1/2 inch? this mobile home im dealing with i wont see under floor until monday, but Im trying to figure out if osb is required for mobile homes? Mine is 2019 and im told they still use osb? why if plywood is more durable?

This is definitely the video i was looking for the lady before me lived in this trailer for 11 years and didnt do much keep up the floors the ceiling and the porch are what needs to get done i cant afford to get someone to don it so im going to have to do it a little at a time my self ive been here for a year and its mostly the sides and one big spot in the kitchen and the bathroom kids put holes in the the floor on there room from jumping on the bed and my room i cant even sleep in it because the floor is falling in under the window and water leakes from the bathroom for some reason the pipes in the bathroom are inside the house instead of under it

Gonna do it! I just bought a mobile home and definitely needs flooring.

No. You are attaching to nothing. Because the rest of the floor is pressed wood. It will tear out and fall. You must go horizontal and out blocking under edges from joist to joist. Not in middle.

How thick is the board

Just what I needed to watch! Thanks bro! Appreciate it!

Nice job. Your narration along with your video was excellent.

I will be doing my own floor

Thank you for this video, this is something we are doing in 1 of our bedrooms next weekend.

We're about to have to do this at our house

Why didn’t you affix the 2x4s to the other joists?

Exceptional work, working on the laundry next. That's my next project. The subfloor if rotten all the way under the door.

Thank you. We had a small leak in a waterline for our washing machine that we didn't notice until it was too late. That's taken care of, but now we have a bulge in our hallway. I've had floor issues in the past, but those were in stick built homes, not a manufactured as we're in now. It looks like the hardest part for me will be taking up the current flooring (lvp) without damaging it so I can take care of the repair.

Thank you! This is the very first video I have found with the exact problem i have. Now i know what is probably the cause of mine too. Probably the same as yours. Thank you so much for this! Now i know i need some bracing. I wondered what to do there.

Did you put in the vinyl flooring yet? I'm going to do the same to my double wide, and I'm worried about going over the marriage line.

Great job! Thanks for making this video. I was intimidated by the idea of replacing subfloor, but now I'm actually excited. You just gained a subscriber.

Thank you.y problem area is going out the door.. But same problem. Iam going to do this !! Ty

Instead of attaching the new 2x4's to the subfloor, why not just create a box attached to the joists?

I like this diy I learned alot thank you

What did you attach the braces to? The sound cut out as you attached them. It looked like they were attached to the other subflooring next to it.

Thanks for the FYI. 👍🏻

Helps me UT with somebody with lil knowledge such as myself ...so thanks

Thank you for the information

The oscillating tool work well for that.

Thanks for the video, gonna give it a try. I have a subfloor to a door way outside of the trailer. Got any tips?

How much would something like this cost? Guesstimate for just one small spot.

This just gave me the confidence to get it done

Very helpful! My washing machine hose had a slow leak. Now I have a floor to tackle.

Does that help when there is a lift on floor like a bump in floor ?

Thank u just what ineeded

Hmm interesting 👍🏼👍🏼

That looks like aspen board not particle board which is definitely better

Great presentation !

I have a 50 year old mobile home that I’m slowly working on. I just ordered new roof trusses to peak my roof, I’m thinking of replacing my furnace and doing all my ductwork in the attic space which will be conditioned. Then I’ll be doing a full repipe and replacing a good chunk of subfloor.

Great job ! Fix'n to replace water. Damaged floor had a water leak Any suggestions on how to check for future leaks Thanks for your help

Thanks for sharing..good information..and I might need it soon in my old mobile home. Lol I thought I was the only one that said WONKY🤣🤣 until next time..God Bless your family

This has reduced my fears a whole lot. Thank you so much!! I will attack the job myself (with a helper) but I will not use OSB for the repair; most likely I will opt for plywood.

I always replace my insulation and put felt paper on top of the duct work when I have to repair a spot to prevent water condensation from ruining the floor again. And I use plywood instead of OSB chip board.

i had to put automatic vents under my dad,s place they work grate ever 12 ft it was getting mold if air can,t get under a house to much moister

Been awhile since I repaired a manufacture home floor. The one I am living in now is about 23 years old and my back door was leaking in at the knob latch. First time I have had this problem. I stopped the leak and now will repair the small soft spot just below the corner of the door. This help refresh my memory on how to do it.

It helped me. My sub floor is loosing by the entry of the office or middle room. It is by a vent. I have to clean out my and make the repair. You explained every i have to do. Thank you so much!

couple recommendations. go joist to joist with 2x4 / 2x6 instead of the small pieces connecting old to new. toenail into joists. also, cut out the pieces in 4' sections (width of old piece, not multiple pieces) so weight is distributed to the max

Thanks for sharing I appreciate the video and should be a pretty simple fix now and off I go to work the magic and seems like it will do all I need and look good as well so thanks again.

Thank you for this video. Looks like a fix I can do. Appreciate this.

Looks good.

Looks great.

im having the same issue what did you do to stop the ace duck connectors from sweating??

Thank you for making this video.

Thank you, brother. I appreciate the video!!😊

Nice job.

Glad you keep up with floor repairs. 💞🎄☃️🎄🎅

I hate when the subfloor is glued down with staples. It makes it ten times harder to pull up. I always use a flush cutter to clean the top of the joists off. You did a good job with all the bracing. keep up the good work guys!

Who would you recommend to find out why you have a soft spot? Our home is only 5 yrs old and we have soft spots not close to water. A contractor or maybe a home inspector?

I’m about to have to fix a sub floor in the add on. Thank you so much for this very helpful video! Great Job!

Thank you for sharing!

My next project,

Thanks much very educational!

lol

Thank you was explained very way
