My dad and I are replacing some in a house he just bought to sell to me. Pretty easy, besides knocking out the older ones. Takes some time plus pretty messy haha. But we placed a tarp under us so we can just pull the tarp out and not have a huge mess under the house.

[@waynethomas8930]

I’ve been renovating older houses for a long time, and I’ve yet to see a floor from circa 1930 have a level enough joists to sister up! You guys must hav go really lucky here. I’ve had to start with fresh lumber and a laser every time.

[@bnasty267]

For future reference, I really like the Simpson SDS 3" structure screws for sistering. You don't need to waste time pre-drilling, and the screw is designed (no threads near the top) to pull the boards tight. They aren't cheap, but they're probably cheaper than the total cost of a carriage bolt, washer, and nut, and definitely worth it for the time savings.

[@DoAndBrewDIY]

Howdy bnasty267! That's a great tip....thanks!

[@AndrewHelgeCox]

04:00 When you had to put a new joist across the full span and cut out a chunk of the old one, why did you sister the old and new instead of ripping the whole old joust out?

[@DoAndBrewDIY]

Howdy Andrew Cox! Good question - I should have mentioned this in the video...this is a relatively small house and the joists under the kitchen floor run all the way to the front of the house (under the dining room). I wanted to ensure the dining room floor remained true, so I took the extra time to sister all the joists that needed repair. My concern was that if I cut the joist off mid span, it could lead to some issues with the dining room floor later. It would have been easier to cut and replace the kitchen floor joists, but I wanted to play it safe and tie the two floor together - as it was initially built 75 years ago. Thanks for the question...hope to see you as a sub! ☘️

[@awt]

It looks like you're sistering the old joists with new joists of the same dimension. Why did you keep any of the old joists, as opposed to just replacing them entirely? Was it just to make the floor stronger than it was previously?

[@nehnehnehbatman]

Thank you

[@RushAustin]

It looks like you are setting the new, un-PT joist right on masonry with no barrier between. Maybe the new joists are PT and I just missed that part. Also, old vinyl/linoleum often contained asbestos. Be safe, send samples off for testing before cutting through old linoleum.

[@straighttrippingmusic]

How long did it take just to get that initial demo done.. getting to the joists underneath subfloor. nice video.. thanks for sharing!

[@DoAndBrewDIY]

Thanks for checking out the video! It took three guys about 6 hours to complete the demo, pull all the old nails, clean up and put all the debris in the dumpster….so about 18 man hours.

[@georgiapoodlerescue2878]

Thank you for this direct and to the point video. I will be doing exactly what you showed. Regarding the mold issues others have mentioned, bleach only kills mold on non porous items. It does not penetrate the wood and does not reach the root of the mold behind the wood. It grows back because it was never killed to begin with. I've read Concrobium products are good and Biocide products as well. Both have good mold foggers to kill the aurborne mold spores and to do the same in hvac systems. I've also read that spraying the wood with peroxide gets to the root. Leave on for 15 min then wipe off. Then some followup with pure white vinegar, leave on for an hour then wipe off. It didn't seem you used joist hangars because you had a solid brick base. I guess those hangars are only needed if the house is jacked up on periodic cinder blocks? Or is toenailing still acceptable in places of joists?

Nice work. I have a lot of trouble with termites so I’d have used pressure treated lumber (or at least soaked the joist ends in copper solution) and tried to install a metal termite shield where I could.

[@sjd7188]

Get the house termite treated and if you are in a very termite active area get traps put in the ground outside your house

So can I just take like 5ft back with new joists? The rot on my floor was 3 ft long on each. I was gonna cut 5 foot and sister them up and put support under where I sister it in.

Thanks for the video! You mention tile on plywoood is bad - what is the right way - are you talking about cement board? For a bathroom, I think they put that orange dykstra(sp) - curuious about kitchens.

[@DoAndBrewDIY]

Howdy boe dillard! Yes - installing tile directly onto any wood surface is NOT advised. Simple reason is that wood moves with changes in temperature and humidity. As the wood expands and contracts the tile or stone will eventually pop loose. You need to have something that separates (de-couples) the tile/stone from the wood subfloor; like cement board or the orange membrane you mentioned - which is a Schluter-Ditra product. Here is the link: www.schluter.com/schluter-us/en_US/ I have not used The Schluter membrane yet. It is both a de-coupling membrane and a waterproofing membrane in one. I still prefer to use the cement board with a paint on waterproofer like RedGard. Some of the real ol’timer tile setters would use old laminate flooring as a ‘slip sheet’ to separate the tile from the wood subfloor. Hope this answers your question. Thanks for checking out the video and good luck on your project! ☘️

Do And Brew - DIY are the carriage bolts required? I’ve only seen people use screws in the past

[@alexanderjamieson7971]

@@josephdaoud5868 deck screws lack sheer strength and can break under live load movement. This is a kitchen where heavy appliances will be moved in and out over the years in addition to a lot of foot traffic. The carriage bolts also tighten up the sistered joists to help eliminate movement between them. This is very important if installing tiled flooring

[@missjuhee]

Great video! I will be getting my kitchen floor repair due to water damage soon and was wondering if I need to treat for mold. We have fixed the source of the leak. I know you cut out the rotten part but can I spray the affected areas with some sort of treatment for any mold or fungal infection? Thank you!

[@DoAndBrewDIY]

Howdy Juhee Ha! Mold is tricky. Honestly, if you are concerned about mold, the best advice I can give you is to contact a professional mold remediation company. You can spray with breach or ammonia and try to scrub it away - but you are dealing with a microscopic enemy; can you ever be sure to get it all? I have used bleach OR ammonia with varying degrees of success. (NEVER MIX BLEACH AND AMMONIA!). I recently read an article that in some cases when bleach is applied, the mold will retreat out of site, but come back stronger later - even feeding off the bleach! So, if you have a serious mold problem or you are sensitive to mold, it might be best to contact the pros. Thanks for watching and good luck on your project! ☘️

I have watched many a video where people say, it was done like this in the day and we no longer do it like that. Now for my question. Why do many if not all contractors glue and screw subfloor? Won't it be almost impossible to rip up old floor the next time it is in need of repair? It is not like the old days where they nailed and the nails pop up with time. Many are using screws which hold much tighter than nails... I am just thinking out loud and would like your thoughts on the subject... Sp I expect to hear, some time in the future, that glueing and screwing was the way they were doing it in the day, but it was overkill...

Thanks Pete…local code prohibits the use of PT lumber indoors - except for sill plates. Thanks for checking out the video! ☘️

Howdy gutiersa! Glad you liked the video. Thanks for watching and for the nice comment! ☘️

Quick question, are you using pressure treated??

[@DoAndBrewDIY]

Howdy Raised ByWolves! No...you might think that pressure treated wood would be the best option, but it’s not advisable to use treated wood inside a home because it can off gas the treatment chemicals for many years. Thanks for the good question! ☘️

[@stanleysiewierski]

@@DoAndBrewDIY Actually the logic in using PTL in a "finished" basement is flawed. I wouldn't advise putting PTL in living spaces "ie finished basements" although PTL is used as a sill but that basement is not even a crawl space. The only purpose of the preservative is to prevent rot and insect infestation and I think that basement fits the bill. It is generally accepted that the most risk from PT wood is in the construction phase where fine arsenic laced sawdust is easily inhaled or comes in contact with the skin. Although on another topic many of the plastics and paints that we have indoors, food containers included tend to off gas . I would never used spray foam to insulate a house either, that's a ticking time bomb.

How far apart are your single carriage bolts?

[@DoAndBrewDIY]

Howdy Charles Richardson! The carriage bolts are approximately 8 to 10 inches on center. Not all sistering methods include carriage bolts - some folks think it’s overkill - but we only have one shot to get it right and I prefer the added security through bolting provides. Thanks for the question and for checking out the video! Let me know if you have any more questions. ☘️

Beginner here. I notice that your joists align with your wall studs, is this standard? Thanks for the video!

[@mikeznel6048]

It’s something you want to try and do. Studs land on joists and rafters land on studs. It’s good practice and transfers the load better.

Q: I have a 71 y.o. house, the 2x8" joists (in my kitchen area about 10' x 12' which is over a basement) are not rotted at all and only a few sag about 1/4" lower than the others. I just cut out the 3/4" pine sub-floor because I want to install tile thus need the floor to be stiff (going to use 3/4" Advantech OSB glued and screwed + 1/2" Hardie backer boards, than the tiles). At first I thought all I need to do is replace the pine cross braces with strong steel versions, but now I think that will only keep the floor from feeling bouncy and not really add much to the load bearing ability. Now my concern is that the 2x8" floor joists are going to sag over time due to the added weight of a tile, then they'll crack. Is sistering the joists the only way to add strength? Do I really need to add strength if the original joists are in good condition?

[@DoAndBrewDIY]

Howdy zzubuzz! Since you have the subfloor up, I would sister in 2x8 or 2x10 to the sagging joists. I would use joists that long enough to be supported on both ends, then through bolt to connect (sister) the new joist to the old. This will help to remove the sag and add strength to your floor. Good luck and let me know if you have any more questions. ☘️

Do you even need a jack with this method?

[@DoAndBrewDIY]

Howdy Ugo Okafori! Great question - a jack is usually not required because the majority of the weight is off the joists. However, as with these joists that extend under the dining room on the other side of the house, you may need a little extra lift to get the joist to level. Usually a helper can hold the joist level as you sister the new joist to the old...if necessary, a jack could hold everything level as you get the new joist installed. Thanks for the question and for checking out the video! ☘️

Is this fix approved by a structural engineer or a city inspector?

[@DoAndBrewDIY]

This is a centuries old technique to repair the support structure of a floor. It is allowed in my state. You should verify with your local building codes. ☘️

I have a question, what if open a small or a big hole in the tubes that are placed under the floor? By the way, very nice job!

[@justinballard7242]

You should if used a pressure treated plate on top of that concrete wall. Concrete should never touch untreated wood

[@proteus1]

You say don't have sheets finishing the same when putting down the floor boards...Why would this matter?

[@DoAndBrewDIY]

Howdy David Patheyjohns! It makes for a weaker joint. So you should avoid having four corners together at the same point. Thanks for the question...let me know if you have more questions. Good luck with your project! ☘️
