"Sistering" a Cracked Broken Floor Joist

In this video I "sister" up a cracked floor joist. All I wanted to accomplish with this was to remove the previous repair and add some strength to the existing joist. Though I do talk about leveling the floor, I do not level mine because I am only supporting this one spot. If I was to level the floor (as much as my 1946 built house would allow) I would have to sister every single joist and that is not necessary in my case. I hope you enjoy the video! Thanks for watching!

I had to look into the term "sistering". There were a few but the one I liked best was, when one is having trouble carrying the load, the other comes along to help bear the burden = sistering. As always, I love these videos! 👍🏼

@Marcelo-56 2 года назад

What happens with the expression "twinning" is that it is an old Latin word that is used in the field language🤷‍♂️

@scottbriggs7299 Год назад

I would have C-Clamped them together rather than using screws to pull together. This assure a better bond for the adhesive. So First apply the adhesive, then C-clamp together, then finally add screws to finish. Hear in Texas we call that a Sandwiched Beam or Rafter if 2 sided. Sistering if 1 sided. Other wise.....Very Clear Detail and Running Explanation and Video.!! Scott Briggs, 82. Luxury Custom Home Builder 38 years.

@radchander 2 года назад

I learnt it the hard way, attaching the support with a couple of screws so that it doesn’t fall and create damages. I was working with my son to replace a porch 4x4 post. Didn’t screw the temporary support sitting on a jack. When we made a small adjustment the support fell down and hit a garden shovel in the vicinity. The broken metal spade portion was thrown off about 10’ and the remaining broken handle swung and made a hash on my son’s shin. Fortunately he has forgiven his father for his stupidity

I've sistered every second joist in my century home and boy it was a fun experience. I used bessy clamps to suck the 2 boards together which helped a lot. Great video bro!👍

Good clamps especially the padded kitchen cabinet clamps to help align as you secure the cabinet to the wall

@empice2k 2 года назад

Where I’m from we call that ‘marrying two boards’. Also, I’ve used a couple of C-clamps to bring 2 boards together. I only know that because about 4 years ago I had to strengthen some floor joists in my 1972 mobile home under what had been the bathroom. The original floor joists were rotten on top in places and so there wasn’t much area to nail down the plywood. The solution, I felt, was to marry (in one instance sandwich) new boards to the old ones. I used large C-clamps to force the boards together while I ran screws into them.

Came back here to say - THANK YOU. You saved me a bunch of missteps. And you're the only one I saw that advised to screw the jack to the old joist, that trick saved my TV several times for sure. I was repairing a 16' span and the jack kept getting lifted and became useless, so I quit using it and used a 2lb sledge to whack the joist into place. Floor is rock solid now! Thanks a ton, man.

@TheNixonification 2 года назад

The only thing I would do differently is nail it as well. Screws have alot of clamping force, but can shear vs nails which can pull out, but have better shear resistance.

@TheFixerHomeRepair 2 года назад

Yeah I will probably add a bunch of nails. I wasn’t satisfied with what I had there after an hour or so and I have a bunch of spikes so probably gonna go nuts with the nail gun. 😁😁👍

@fev3rd 2 года назад

Depends on the screw or situation. We don't know what is above or the load but all he did was make a double. Some screws are structural, but he did say construction screws. I'm thinking home Depot there cheap construction screws looks like the expensive grx sold at Lowes. Spax at home Depot are said to be structural screws

@Loonypapa 2 года назад

Depending on what brand and rating of structural screw you chose, screws will actually handle quite a bit of shear if you array them properly.

@dougmiyamoto3109 Год назад

You can use GRK screws that have the shear strength of a nail, with the clamp of a screw. Expensive though. And I always clamp the boards together as well before fastening.

@ajmedeiros77 Год назад

Timber locks or head locks are way way stronger than any nail. They make the red ones specifically to attach lvl’s together, but people are in a hurry and want to cut corners and use Nails

Had the same issue in my 1975 house... right in the middle of the dinning room floor. One 2x10" joist had a huge knot that weakened and cracked all the way through, top to bottom. The builder never should have used it in the first place. I added a 3/4" plywood "sister" on *both* sides after carefully jacking it back up in place about 3/4"... construction glued and screwed, 48x10". Did the trick and solid as new.

@TheFixerHomeRepair 2 года назад

Yes! Plywood on both sides with glue almost turns the joist into an engineered piece of lumber! Does a great job! Thanks for sharing!!

@tecenter 2 месяца назад

Those floor joists look familiar and I have a few above our kitchen that need repair too due to bath remodel plumbing. I did one of the over notched joists a foot of two from the corner of the house under the second story floor. It was not fun. The other is under the tub and the joist is already sistered, and both are notched so much the floor sags while in the shower and the plumbing leaks almost even time, unless we stand back far enough from the tub drain to keep the floor from bowing. If it were the only problem I would have tackled it long ago like some of the other plumbing I've adjusted to reduce other code issues. but I'm still left with 3 that I know I need to address. It's nice to see a youtube about a house that was built with similar materials as mine and I look forward to searching your channel for more ideas on how to address my future attempts to repair our houses bath remodel issues. :) And possibly some other ideas besides.

My nickel on the ground, Sister is a shipwright term when pairing up the frames of wooden boats to strength them as each frame is different form the next they have to be made individually to mate together. By the way i was taught wiring cleats have to be a hammer length apart with the nail underneath to support the wire.🔨⚒🛠

It is a relationship thing. Much like you have motherboards and daughter boards, this describes the main use item and the secondary item such as video cards, PCI cards, etc, you also have sister items, they are the same but different. In this case, they are the same board, doing the same job, side by side, but not the same item. So they are sisters. In order to be a sister, there must be at least 2 of them.

If you really want to add additional strength I would suggest adding a piece of 1/2" OSB sandwiched between the two joists and alternate ledge locker screws installed from opposite sides. The OSB is incredibly strong in the vertical orientation and is found in most new construction for that reason. I did this in my home when replacing a shower stall with a large 2 person jetted tub in a bathroom remodeling project.

Professionals generally consider nailing two boards together a double girder, while adding an identical board to an existing joist, a sister. I suppose the boards have to be dimensionally identical for it to be “sistering”.

@hellotwinkie 2 года назад

I am so inspired! You have access at both ends for the new sistered joist to sit on. Would your be comfortable if you only had access on one end? Also what’s the difference between the screws you used here vs the Timberlok you used in a different video?

@TheFixerHomeRepair 2 года назад

Hey! If I only had access to one end it would depend on the situation. In this case, for example, if the end I had access to was on the side that the joist was broken then I would be ok with just attaching it to the old joist. If it was the opposite I would be less comfortable. As far as the screws, these ones are smaller and do not have as much shear strength as the timberloks. I would have used timberloks on this but didn't have them on hand. That is ok though because there was not much weight on this joist. Hope this helps. Thanks for watching!!

@robertginther9248 2 года назад

Pull the two boards together with a big "C" clamp as you go across. Screws are very hard (brittle) so the will shear. Nails aren't hardened, so they will not. I would have checked the straightness of the original vertically with a taught string. Looks like your floor has a sag in the middle. Best way would have been through bolting with big fender washers with 3/8 bolts.
