Repairing Rotted Subfloor In Bathroom
Вставка
- Опубліковано 5 вер 2024
- Repairing rotted sub-floor In the bathroom is our task for today. When tile is improperly installed without the correct underlayment it can create deflection. When this happens, it can cause the grout to crack and eventually the tile to crack. Eventually water finds a home in the crack and starts breeding mold. If you have this going on, it is time to tear it out. Join me on my journey to replacing rotted subfloor in this bathroom.

Wow looks expensive and time consuming
What would the cost be for that much work.
@Sooperdooper74 I would estimate for a room this size you could get most of the materials for around $800.00, then you could do it yourself. If you had it done by someone. Probably around $2,500.00 to $3,000.00. About a week's worth of work may be a little more depending on how much time is dedicated to it. Hope that helps. Thanks for the question
I’m in process of doing this to. No support for the toilet, so it flexed, leaked, rotted the subfloor, and caused mold. We removed the toilet, the tile, the luan and will be removing a 2x3 ft section of subfloor and replacing it with plywood. We will also be installing more cross bracing between the floor joists. House was built in 1988 , and the joists span 32 feet! This job is way worse than what i am doing though! Kudos to this guy!
Thank you. Good luck with all your projects. Thanks for the comment
Excellent job
Need u to replace my floor
@maryshutty1515 thank you
How much did it cost?
Great video! Actually redoing a 1960s house and have this exact issue. Thanks for the tips!
You got it, Frank. Thanks for the comment. Good luck with your project
Are there no building standards in the USA? I have now done several houses with rot around the toilet and in every case the house was designed poorly with too much flex in the floor. Plus, the wood is never pre-treated for resistance to rot, nor is the wood, membrane sealed. What I end up doing, for smaller jobs, is reinforcing the joists around the toilet (in particular) and adding cross-joists for support in critical areas. I also pre-treat the wood to be rot and water resistant, which I repeat after installation. In critical areas I use 3/4 inch hardwood. It seems to me fundamentally wrong that builder are allowed to get away with this kind of practice.
Depends when the house is built. Doesn’t matter what “standards” start to get implemented houses prior to that won’t adhere to those standards. That’s where renovations come into play
Build and repair is VERY expensive so people often opt for unlicensed "handyman" types that are much cheaper than competent professionals. This work is typically done by illegal aliens from Mexico or South America that may work on construction sites etc and do this sort of thing on the side. They cut a lot of corners because it makes jobs go faster and uses less materials.
@@GalacticEggNot withstanding your observation is no doubt correct, the overall standard of construction in Arizona nearly beggars belief. I am currently replacing a shower which was 'as installed by the builder'. The one-piece shower lacked any mortar support and instead relied on two, half inch thick, planks of wood embedded in the fiberglass pan. Unfortunately these pieces of wood were not contiguous because of the need for the shower to slope towards the drain. Anyhow, after 15 years the wood (and the fiberglass) gave up and collapsed. After stripping out the old shower I found the plumbing consisted of a moen rough in which was floating in mid air, secured only by two straps around hot/cold PEX piping and the copper sweat joint leading up to the shower head. The PEX pipes (and also one going to the bath) were wound around studs so they impinged on the shower walls. To proceed I had to disconnect these pipes, drill holes through the studs, reinforce the studs (for other reasons) and then reconnect them. All because the original builder's plumber was a lazy piece of c**p. Sadly, this is all too common (aalong with numerous code violations that required my intervention). The electrics were no better and the installation of the (original) HVAC was a disgrace. This is typical of so-called professionals in Arizona. They are a joke.
@@davidgapp1457 This is what you get when laborers build a house instead of skilled carpenters and plumbers.
Everyone wants it cheap cheap cheap, until you have to repair all of the damage from their poor workmanship and low quality materials.
@@davidparker9676 I completely agree with you. I would be willing to pay extra for quality workmanship. In the end I guess the only solution is to design and build your own house, and if I'd had time I would've done so. What is annoying is that builder do not give you the option of having premium solutions and superior workmen onsite. I suspect they don't want your neighbors to become aware of just how poorly their own houses are constructed. Seriously! For instance, bringing the hvac ducting inside the cooled space. Either way, the builders just don't give a damn and they were 100% intransigent.
That molding cut & work-around tho! Very nice!
I appreciate that. Thanks for the comment
You made this look so easy!!! Help!!! Our home needs your help please. We are going through this exact same issue.
So are we!🤬
Yes we are too 😞
Me too!!
@kkbird21 I’m in the Nashville area. Let me know if you’re close
@YOUFLOOR I wish! I'm in SoCal (❤ Nashville tho)! I just removed my old fiberglass tub/shower unit and discovered the subfloor is in good shape- phew. So just need to replace around toilet. I was quoted $650 and $1400 by plumbers to replace the flange! So I'm rewatching your video to inspire the next part of my reno project😊
Why is there no cement board/durock underneath the floor to begin with? I've never seen anyone put porcelain tile straight to particle wood board/ plywood.
I absolutely agree 100%. Lots wrong with this installation. Thanks for the comment
I just pulled out a bathroom floor that was 30+ years old which had 6" ceramic tile glued right on top of linoleum sheet flooring and 3/4" subfloor. The only tile I found to be cracked was under the toilet. Both toilet and bathtub drain had leaked for years rotting out sections of subfloor but the tile and grout held up. Crazy...
@sonofhal9245 Wow, that is all very interesting. Thanks for sharing
Hard work just ripped out our main bathroom & tub combo down to the floor joists. I had to 5/8 triple plywood the subfloor for a slight pitch 14" to the stack. We had to use self-level plus the tub area no ceiling access below only the closet access door by the faucet. Our joists were running front to back the existing 1' 1/4" (1964 Bi-level) copper drain was capped off & previous homeowner modified a new drain 1' 1/2" PVC through the ceiling rerouted down to another exist copper discharge pipe. I had no option but to use that 1' 1/2" PVC drain.
OUCH 🙏🏼🙏🏼🙏🏼
Would it not be beneficial to use some sort of water proofing agent on the floor boards since it is in a bathroom ?
Just found your channel and subscribed. Great video; nice and tight job on the sub-floor and toilet flange! I have a project I'm about to attack in my kitchen; tile is cracking and popping. Probably wet rot and moldy subfloors; hopefully not the floor joists!
Well, I hope it runs smoothly. Hey, if you have any questions, you can send pics and email me when you are on your project. If I can help, I'd be glad to give any guidance with stuff I have prior experience on. Thanks for all the feedback. Email is youfloor.net@gmail.com
Nice detail work. I'd never rip out tile without gloves considering the sharp edges. When possible, first examining the underside of the floor via crawl space or cellar ought to be done to anticipate what surprises await. How was the new floor waterproofed to prevent recurrence?
The flange needs to be above the finished floor. Whoever installed the tile had the flange lower than the floor and the wax ring leaked for years. Yes, the issue was fixed with the new flooring. Thanks for the question
I love the way you did the bathroom
Thanks. I love the way it turned out. Thanks for the comment
Thank you, very helpful
I had someone remodel my bathroom and instead of removing the old tile they put the new tile on top of that old. Now I can see the toilet leaking in the basement. I think I have something a gap in there when sitting on the toilet.
If the wax ring is not installed correctly it can cause a leak. Might want to have a plumber check to see if it is sealed. Thanks for the comment
Water proofing the floor is a must. May have been water from the tub.
From the damage, I'm guessing I was the wax seal on the toilet that leaked. Was pretty bad. Thanks for the comment
That’s what I was thinking, how would you seal everything up?
What if theres mold hnder the vanity and tub?
I'm afraid to ask but... On average how much does a job like this run?
Very nice. Thanks for the video and sharing your skill with us.
You got it brotha. Thanks for the comment
VERY NICE WORK
Thank you. 👊
great video but one question - when you installed the flange did you only use primer and not cement?
No I used both. Thanks for the question
I like how you kept the toilet supply hose attached basically the entire time lol
Yep. We got lucky it was in the wall and not the floor. Thanks for the comment
haha but like it would have been easier to work around if you disconnecte the hose from the valve. lol@@YOUFLOOR
Thanks for sharing this, it's informative as I face a potentially rotted subfloor. I'm not experienced at this, so take my questions as truly curious ones, right?
At 9:41, is it ideal to have to essentially force in the replacement subfloor? I wonder about allowing room for expansion and avoiding buckling if it swells.
Similar thought about 11:46, would it be better to cut the new pieces a hair smaller to allow for expansion? Trim will cover the gaps against the cabinet, flooring will cover the seams near the toilet pipe. Good work, the results are terrific! You do good work!
What if there is a gap between the subfloor and the tub. How do you account for that? Do I have to raise the subfloor up by using plywood? We are planning on using kerdi membrane. Thank you!!!!
How big is the gap
Half inch! Thank you for the reply!
Where was the water coming from (toilet, sink, shower?) and were you able to fix it to prevent this from happening in the future?
Was the wax seal around toilet. It blew out one side. Yes got it fixed. Thanks for the question
So if water splashes out of the tub will the vinyl flooring keep the water out of the subfloor?
That is how it is supposed to work. A lot of times we will seal the perimeter with silicone to keep any spills on top of the flooring. Tks for the question.
@8:48 would have been the highlight of the video if you had shown us your way of cutting the perfect hole to the toliet flange. How you measured, etc
Here ya go ua-cam.com/users/shorts5T3mkS4bQe4?feature=share
You should invest in some knee pads... Omg they help alot... Bought my own after doing so much jobs
I've tried several kinds. They end up around my shins most of the day so I end up taking them off
Good job!
Ty
@charles boyer I'm reaching out to my commenters to make sure you know I am giving some tools away for Christmas. If you are interested in entering click here for details - - - - - > ua-cam.com/video/iQOXh0b-_dg/v-deo.html
How did you secure the new floor joist next to the wall behind the toilet flange? I have a similar situation going on in my bathroom.
The joint was on 16 in centers. So I cut 2 blocks at 14 and a half inches and And put them in between the existing Joist and then I was able to slip the middle one in and screw it from the ends. I made sure to run the new Joyce just passed both walls. Hope that helps if
You need a diagram, let me know. I'll email you how I did it. Thanks for the question
I have the same problem can you email me the diagram plz
Ok no problem. Have you exposed the crawl space or any joist yet. Send me a pic or 2 to youfloor.net@gmail.com. I will take a look or at least send you a diagram of how yo head off a joist, Z
Beautiful!!!!!
Thank you. Was a lot of work. So I appreciate that.
Man if I had even a guest bathroom I would do this myself for my bathroom. But I might have to demo my bathtub with how long we had water damage
Yeah. Can be a pain. But it pays off in the end. Good luck on your project
Think it's safe to take the baseboards off lol
Yep
Hard work and looks Grand
Ty and thanks for the comment
Have you tried Advantec subfloor? They say it’s better and stronger then plywood
Shouldn't the flange go on the inside of the pipe?
You should have placed a tile underneath for the proper spacing.
Spacing for what. And I'm not using tile. Sorry, I don't understand the comment
Question what if the rot is in the joist, how to you fix that?
You will have to replace the joist check out my other channel (RENT THIS FLIP THAT) I have a few videos on there replacing joist and rotted band. Thanks for the question. Hope that helps
@@YOUFLOOR thanks
You good man! 💯
Ty
That toilet has been leaking and rotted out the floor I bet.
100
You are probably right. I have seen this problem happened more times than I can count in my years of installing floor
Yup. About to do this same job for my parents' old house. They've had a toilet donut leaking for years, and it's rotted out the floor.
Good luck. Lots of work but super satisfying when it's complete. Thanks for the comment Jenna
yeah my spare bathroom is like that, half the way done .. got everything ripped out, now floor and toilet flange, new cabinet, flooring etc.
Hi, it seems that you're local. I could really use your help. I'm near Mt. Juliet, TN. My hald bath is currently unusable because of a rotten subfloor. Would love some help.
Yes ma'am. Send me some detailed pics and a small description. I'll take a look and get back to you. Thanks for the question. Youfloor.net@gmail.com
This is the exact same thing I am doing in my bathroom, except putting in a new cabinet, but that's not a big deal...
Right on. You got this. Make sure the toilet flange is on top of finished floor. Not just on top of subfloor. This will ensure a good seal. Thanks for the comment
How much would you charge for that floor job, trim and down?
How much would a job like this cost? I'm looking to do this for my parents house. Thank you
Sirrrrr lol I knew that floor was gonna push thru 2 seconds before it did, I'm like why are you standing on it if you feel it is so soft! 😭
Good job, nonetheless the vanity should had been removed and entire floor removed replaced and plumbing redone. Do it right while its in demo mode. 😢
Okay. Thanks for your opinion 👍
I totally agree and if I’m trying to get a subfloor tht needs to be 1 inch I’d prefer to use 3/4 & then 1/4 inch….just bcuz you double 1/2 inch tht doesn’t mean you eliminate deflection….entire subfloor should have been removed and next time redo all the plumbing,block in around the toilet drain so tht its more secure when bolting/screwing to the floor and use pressure treated plywood.
There was also some joist rot he should have addressed as well.
How the hell did you get that pipe off so clean. Mines glued like fucking. Easy there’s no way I can get it off
No water proofing under the
flooring ?
Like what. What would you put on a wood subfloor to water
Proof it
What size of screw did you use for subfloor?
2 and a quarter start head is usually mt preference. 2 inch and shorter usually has a thinner shank. They tend to break sometimes going into floor joist. Hope that helps. Thanks for the question
I hate when people throw dirt in the crawlspace and attic 😒
I hate when they throw trash in there😝
getting estimates for this now and everyone says they need to take out the vanity too? 🤷
Every situation is different. I crawled under the house and inspected the subfloor closely. I didn’t feel in was necessary in my case as the rot did not spread that far. Guess I got lucky. Thanks for the comment
If I'm hiring someone to do this what do u I call that person?
Do you service central city ky?
No sorry
Looks like you only put the purple primer on the flange and forgot the cement glue , you need both
At 11 :41 in the video, you can see me putting the lid back on the glue. Didn't wanna do a tutorial on how to install a flange. More focused on replacing the subfloor. The glue just happened to be off camera. But you are right... it does need both. Thanks for the comment 😁
What was the cost? Thanks
Not too bad, but the subfloor repair was around $150. In materials. With new flooring, it was around $500 total. Only took about 5 boxes of flooring
Is that the cost just for parts, or is that cost for parts and labor?
It was for parts only. Would probably run $800 for labour's. 2 days. (Depending on the situation) so around $1,200 to $1,500 for the whole thing. Hope that helps. Thanks for the question
Good job! My small 5’x7’ bathroom needs the entire subfloor replaced and some joist sistering. Tub is 4.5’x2.5’ cast iron. Think it can be removed without having to break it up? Just me doing the job. If it does need to be broken up how would you suggest doing it?
@tmise50 Maybe. If you can turn it sideways, it may fit. A lot of bathroom openings are 28 to 30 inches, so if you took the door off the hinges, you might get lucky. Thanks for the question, and good luck with your project
It was a little hard to follow. What did you end up putting in as sub floor? You talked about 3/4 inch and also two layers of half. Also did you end up putting a layer over the sub floor?
I doubled up the half inch, and no, I did not cap it with anything. Hope that helps. Thanks for the question
I would prefer Cement backerboard for subfloor.
For LVP? Sounds like a waste of money. But we all have our preferences. Thanks for the comment
You just left it the same, with no extra support! Now it will do the same damn thing, and the tiles will break as well. You should have added 2x6 between the joints for more support !
No extrat support needed. It's lvp. Not tile. Thanks for the comment
Why didn’t you waterproof the floor?
It's water proff flooring. What do you mean?. Thanks for the question
I would gut that " to the studs" to be safe.
If lumber wasn't so high at the time, I might have considered it. But I check under the house and in the walls. I think I got it all. Thanks for the comment
@@YOUFLOOR I did a similar remodel earlier this year. Wasn't as much damage but a little water causes the 3/4 inch plywood to de-laminate. Replaced the worst part then oil base primed the subfloor. I do love LVP. Will never tile another floor. LOL.
Right on brotha. 👊
I can almost guarantee the floor is rotten under the tub and the sink
Almost.... good thing I went under the house and poked all around to ensure I removed all the rot. Thanks for the comment
flange goes on top of FINISHED floor . NOT subfloor
You are correct. Which is what I said at 11:25 in the video. Thanks for the comment
my bad
No problem
Don't blame owners weight. A poor leveling job by contractor.
Definitely cockroaches are crawling up
