        How to fix a notch floor joist. Sign In/Join 
        posted
        I have 3 notched 16x8x2 standard floor joists in my basement. The notch is the same size in each joist. The notch is almost in the center of the joist and measures 4 1/2 inches wide by 2 1/2 inches high. In order for my basement to pass inspection I have to repair them. I am going to sister the joist but I didn't know how long the sister joist has to be in order to pass inspection. Do I have to sister the whole joist or is there a minimum length the sister joist can be? Additionally, do I have to sister both sides of the notched joist? Please advise and many thanks!

        butcher job....cant do that. you can bore a hole in the middle. but not the edge. . call your inspector, have him look at it. and give you his recomendation
        by being up front, and asking him what he thinks
        he may cut you a little slack. . you said, there all like that. . your joist is trashed...
        some of em are ok guys and understand. some are hard nosed

        I can give a half answer - You should be able to sister a scab over the bad area. 2' to 3' on either side of the cut area (total patch 4' to 6' long) should do it. However, this amount will vary by each local code department. Some may even require a full length sister joist. So the best thing to do is to call and tell them what you have and what you plan to do - get their blessing in advance as to what they will pass and you'll be fine without doing too much.

        The most you'll have to do is one full length sister joist. There is no reason to sister on both sides as the single sister will be just as strong as the original.

        use a good construction adhesive as well as screws or nails when you sister those joints.

        Good advice all. Notching the bottom is the absolute worst place to cut into a joist. You have effectively turned that 2x8 into a 2x6.

        Spam bump.


        General Disclaimer

        Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

        My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

        notch and tenon, or hole and peg, construction of structure is a specialized art done by craftsmen. it is not "taught," it is apprenticed. Joe Timeclock might think he's going to git 'er dun, but his work won't last. the Timeclocks of this world need to stick with over-stud, brackets, and nails.

        And what ever your inspector instructs you to do get him to sign off on it.
