What causes floor joist to crack?

Repairing Floor Joists Cracked By Water Damage:

If your floor joists have cracks caused by water damage, then it will take some time before they are repaired properly. You need to make sure that the water damage has not affected the structural strength of the wall or ceiling around the damaged area. So if you have a large hole in one part of your house, but no other parts are affected, then repairing all damaged areas at once may be difficult. But if there are several small holes in the same place, then it may be possible to repair them individually.

First thing you need to do is check whether the water damage has penetrated into any of the walls or ceilings where you live. If so, then it would be better to repair those areas first rather than trying to patch up all the damaged areas at once.

How To Repair A Broken Floor Joist?

There are many different ways to repair a broken floor joist. Some methods require special tools while others don’t. For example, you could use a jigsaw or even a circular saw to cut out the damaged section of wood. Another method involves using nails and screws which can be very expensive and labor intensive.

You could try to use drywall screws, nails or staples to patch up the wall. However, you might get frustrated because you cannot see clearly what is going on inside the wall. And if you don’t succeed in fixing the problem right away, then it will probably take longer to fix it completely. Also, drywall screws or nails can cause additional problems later when they become loose and fall out of their sockets.

If you can afford the time and cost of labor, then it might be best to hire a professional in this case. Many people have had good experiences with hiring professionals so there is no need to worry about incompetence or laziness on their part.

How To Fix A Sagging Floor Joist:

Sometimes you may notice that your floor seems to have a slight dip in it.

Cracked Floor Joist:

This is when the wood has cracked, but is still attached at both ends. This is fairly common, but it can be very dangerous. It could easily happen that the wood snaps in two during your next step. You will need to either put a jack underneath the joist from above or put one from below to lift the joist up slightly.

It won’t take much, just enough to take the weight off of it and prevent snapping.

You should quickly run to the nearest hardware store and look for a metal patch or wood patch. You can use either one, because you will need to fill in the gap to prevent more cracking. If you use a metal patch, then you may be able to skip the next step.

You will need to first drill some small holes in the joist on both sides of the crack. This is to prevent the wood from splitting further when you put in the screws. Make sure that the drill bit size is smaller than the screws you are using.

Using drywall screws, start by screwing them into one side at a time. You should probably plan where you want to place them ahead of time because you will only have a small window of time to get this right.

Once you have all of the screws in place, stand on the opposite side of the joist and screw them into the remaining sides.

You may need to trim the metal or wood patch to fit properly. Make sure that it is centered correctly before nailing or screwing it down.

Run your hand over the patch several times to make sure that it is secure. You can always go back and add more nails or screws if needed.

You can now remove the supports you set up earlier.

If the floor was very saggy, then you may want to place a couple of 2x4s (or similar) between the joist to keep it stable until the wood patch has had time to dry and cure.

Now you can replace whatever you removed from above such as baseboards, carpeting, and furniture. Keep in mind that you may have to replace baseboards or shoe molding since these were likely damaged by the support blocks you put in place.

Check your work by pressing up on the joist with your hands several times throughout the day and night. If it feels secure then your work was a success.

After the wood has had time to cure and dry then you can start moving furniture back into place and replace the carpeting if you wish. The goal is to restore everything back to its original state.

If the crack still concerns you even after it has dried and cured then you might want to have a professional look at the problem. This isn’t something that you necessarily need to do, but it never hurts to be safe rather than sorry.
