    Steps for Repairing a Cracked Floor Joist:
    1. Squeeze a generous amount of carpenter's glue into the crack in the floor joist.
    2. Slip an old-work metal joist hanger onto the end of the joist.[BR]
    3. Position a 2x4 post and hydraulic jack directly beneath the cracked end of the joist.
    4. Pump up the jack until the post pushes closed the crack in the joist.
    5. Fasten the hanger to the beam with hanger nails.
    6. Use a cloth to wipe off any excess glue from the joist.
    7. Install cross-bridging or solid blocking between joists to help stiffen the floor.
    8. When notching a joist, all notches should fall within the first or last third of the joist. Never cut a notch into the center third of a joist.
    9. The depth of the notch shouldn't be more than one-sixth the height of the joist.
    10. The length of the notch shouldn't be more than one-third the height of the joist.
    11. Notches should be cut straight and clean with radiused corners.
    12. Reinforce a notched joist by attaching a 3/4-inch plywood strip.
    13. Cut the plywood strip at least as wide as the joist and secure it with construction adhesive and nails.

      That tells me to make sure there is an automatic termination clause in the contract that terminates the contract immediately should the contractor make such incompetent statements.
      It also tells you that the contractor in question could not have passed the state licensing exam which would or should have questions regarding structural support in them.

    Was visiting a friends old house in a college town for a party years ago, and noticed the floor was moving over an inch when things got crazy.
    Thanks to This Old House, my first instinct was to check the joists in the basement. Sure enough, the floor joist underneath the party zone had a massive crack.
    Took awhile for me to explain to the owners the danger of this and to convince them to let me fix it, but I never would’ve known anything was wrong if it hadn’t been for this show.

    I'm in construction and have to deal with people that aren't, almost on a daily basis. I probably wouldn't be explaining the problem unless asked, this is an educational video so explaining is the purpose of it. The reason she didn't understand is that he started a sentence talking about feet and then didn't mention that he was talking about inches by the end of the same sentence. Second time round she got it, it's likely we all have knowledge that the next person doesn't have, especially if they're not in the industry. I speak to sparks (electricians) all the time and I can only guess installations to get the ball rolling. They know I'm not a spark and compensate for that, in the same way they might not understand non-electrical building work, and I compensate for that too. No matter how daft a question or lack of understanding is, it's important to appreciate the persons background. At least she admitted she didn't understand, which is better than many people that just nod and carry on without having learnt something. Keep up the good work!

      Since the bracket, and also the bottom half of the joist, is only supporting a very small part of the load, additional shoring seems pretty unnecessary. Not to say overkill isn't always great, but in this case it does seem like it would not add any value.

    Jack up the sagging area(s) with lally column(s) as needed to level the floor over 6 - 8 -12 months or so. When the floor is level, sister the joists on each with 1/8 or 3/16 steel cut to the width of the joists over the length of the run. Be sure to butt the steel up to the floor above. Through bolt the steel on the ends and on a staggered basis every 12 - 16 inches or so (You might consider stainless steel bolts.). That floor simply will not sag again. Did this with a long unsupported run in a shed with a 4 inch sag in the floor. Now I park the car on the floor...

Use something like a 12 - 18 inch long 2X12 as a foot plate to spread the load on the floor and take your time leveling the structure to avoid stressing the building or cracking wallboard. You may also consider using 90 degree angle iron as a sister rib, depending on the particular situation.

If space permits, C clamps drawn up tightly will hold the sheet metal on either side of the joists. If you wish, when the steel is in place, you can through drill through the first sheet, the joist, and the second sheet to use bolts. Washers and a lock washer will keep the bolts drawn up tight. Hex head bolts are best as you can use two wrenches for maximum tightness.

I will be asking them if angle stock is an option for the size/length I need. My floor joist are (actual 1.5" x just over 7 1/4") 2x8's x approximately 11.5' long.

      @Steve A local machine shop should be able to help you or direct you to a metal seller. A length of strap iron will give one dimensional strength while 90 degree Channel iron is stable in two dimensions; both are very strong for the weight. If steel doesn't work for your application, consider an engineered beam. These are basically very thick plywood beams in a variety of lengths, thicknesses and widths. These can be sistered over the cut joist and would also work well. Hope this helps!

    I would add: If you need a hole to run piping through, or conduit, it's better to do that at the center depth of the joist (center the hole about 4.5" down from the top in a 2x10 joist). This has the smallest effect on the joist's moment of interia (stiffness) and section modulus (strength). Removing material at the top or bottom of a joist has a much larger effect. Drilling a nice round hole in the center works really well from a structural standpoint and seems easier than cutting a rectangular notch. This can be done anywhere along the joist span and I wouldn't lose bat an eye, as long as it's close the center. I'd limit the hole diameter to about 1/4 the joist depth.

      The problem is that once something like wood has settled and creeped into a deflected state, there isn't any realistic option to get that creep back out. You aren't going to just jack the deflected spot and straighten it back out. You probably have to just put new joists up and jack them into a position that lifts the sub-floor back up after you have cut it free from the screwed up spots. I've done the structural design on several house remodels. Sometimes we can get sticking doors on the second floor to stop sticking and windows to open better, but a lot of times, the framing just isn't oriented in a way that you are able to do much about it without more major tear down and rebuild. Sometimes the issue is the sill plate has crushed under an overloaded column and you really aren't fixing that without some removing and rebuilding. A lot of times, you can make it perfectly safe and you stop any more deflection from occurring, but people are just going to have to reset doors and windows and retrim things. You can always redo you floor with shimming under it to get it as level as possible, once you've stopped it from any more movement. There's a reason why the phrase cut to fit and paint to match exists.

    Good job on showing the repair, however if the floor has sagged to a certain extent, the one thing he missed is that the flooring you put in can or will buckle, had to replace the flooring in my laundry room due to the re leveling of the floor. Be aware of this as you may end up replacing that flooring due to re leveling. It will also depend on the type of flooring in place.

    There are appropriate sized nails for all joist hanger applications. However, the length of the nail used in a hanger is generally not the determining strength factor. The nails in a hanger are subjected more to shear or cutting than they are to withdrawal or pulling out. So what really matters is the cross section or thickness of the nail and not the length. There are shorter nails that can be used with hangers that don't degrade the load carrying ability of the hanger, you just have to buy the right ones. There are also screws available that can be used with hangers, but they must be the ones specified by the hanger manufacturer. The general statement that "hanger" nails are no good is incorrect. Using the correct product is always the best option.

    Cutting out a sharp corner introduces high stresses (under load) into a beam, etc. Radiusing the corner greatly reduces the peak stress and spreads it out.
    About 1967 or so Ford racing engines had a high failure rate due to that very thing. When machining a bearing journal or something that had two perpendicular faces, they used a sharp tool to cut into the corner. High RPM, etc caused several failures, before they learned another way to do things.
    They ended up using a slight radius on the cutting tool, something like 1/16" radius. Bingo. No more broken crankshafts.

    Bridging not only transfers load to neighboring joists, but bridging (or aka blocking) also prevents the joist from rolling or twisting, which significantly reduces the maximum load of the joist.

    When I was assigned in the Middle East by my government in 1975 (I was 49 years old by that time) I am also an adventurous guy so I went from village to village and I saw a carpenter doing something strange and he told me he is making Aramaic wood which is wood of the Aramaic Bible. He cuts the timber into very thin, long, rectangular sheets and placed the 1st layer on a very thick and flat metal non-sticking anodized surface that has guiding pins made out of the same material on it's sides, then he brush it with a thick layer of boiling sap resins and places an another one on it and repeats the same process until he has reached the desired thickness and then a non-stick annodized thick metal plate is place on it and his sons and nephews places iron weights on it.
    He said they sometimes use a large number of vices to compress the material. He also said they do not make this woof often anymore except as timber beams and timber posts, joists and rafters and wall frames, stair way supporting frames, floor and wall and stepping stairway foundation planks, foundation door frames and doors only for very well to do traditional families.
    They only do it for the main wood foundation structures only for the hardened and cured sap resins discolors the very thin wood layers as it penetrates and saturates the wood. Then they place a thin layer of the desired wood and use modern wood glue and small nails to cover it with non-discolored wood.
    And it is almost virtually impossible to break because if he takes two pieces of thin wood layers and used the same technique of binding them together and holding them in a very tight vice the layer between the two pieces of wood will not break but only either the outer sides will start to crack but when used as a very thick planks, beams, posts, joists, rafters, stairway supporting frames, etc it is virtually indestructible.
    I asked an Aramaic Priest about the historical background of the Aramaic wood and he said it is the same kind of wood used by Noah to build his Ark! When properly made, hardened, and cured, and seasoned it should last forever and will outlast any metal and stone and clay and ceramics known to man. The gopher wood mentioned in the Chrisian Bible is actually structural laminated wood, only done in the original Pre-Flood methods and techniques.

    Tom mentioned at the end gluing in plywood to help stiffen. We have a 110yr old house with 2x4 roof rafters 24"OC originally with Cedar shake roof. Hip roof with five 18' long 2x4's. Then someone took off the shakes, installed 1/2" plywood on top of the 1x8 roofing boards and then asphalt shingles. The weight made the 2x4 rafters bow 2". We bought the house and seeing the huge space in the attic (covered with 100 yrs of dirt and spider webs), cleaned it all up, and gently jacked up the 2x4s watching a string. It couldn't take more than 1" correction before we starting hearing all kinds of creaking. So we left it at 1" dip. Can hardly see that anyway. Then instead of sistering a 2x6, we took another 2x4 and mated it edge to edge to essentially make a 2x8. We cut 1/2" plywood (not OSB) into 8' long strips 7" wide, completely covered both surfaces with Wood glue and put one plywood strip on each side of the 2x4's. Then we used those "hanger nails" Tom mentioned using. We call them Teco nails. #10. Every 12" 1 1/2" from each edge. Used an air palm nailer and ear muffs. This is stronger than a 2x8 and left us way more room for insulation, which we spray foamed in. Then put 1x8 pine to finish it. We sistered 2x8s to the 2x6 floor (2nd floor ceiling support) and put down 3/4" t&g flooring plywood. Carpeted it, and put in an 8' pool table. Now it's a game room. HS kids love it. Even has a wet bar plumbed in with a small fridge and ice machine. I think we added 20,000 to the value. The county assessor sure loved the tour. ack! Been watching TOH since 1985.
