    Simply an excellent video. One of clearest, most direct I have watched on YouTube. Thank you!

    This is a good common sense approach and a fairly easy solution to a scary problem. I would have no issues doing this in my house after watching this video.
  • I’m a carpenter and general contractor and have been doing structural work for a couple decades. Miracle of miracles, but I find nothing to criticize here. Good work. Where I work, we require full depth blocking, not this diagonal straps. So yeah, can’t believe a diy video on YouTube is good and informative, not dangerously wrong.
  • I am a fan of using some paraffin wax on the friction points such as on the new board bottom sides (at the sill ends) to make the final hammering much easier. It won't affect the holding power of the beam, only the assembly. Not much different from the wedges you remove on the top face. Together they would ease final assembly. Good video.

    The best video I've seen on repairing a joist. Thank you for sharing!

    Super video. One modification I’d make is this : Don’t Jack it up to meet the string line straight edge. Target the jacked up height to align with the bottoms (at that point across the joist) to be just above the same height of the neighboring floor joists. You want the floor to be flat. The neighboring joists will have decades of sag in them and of you Jack this up to a straight bottom , that may push the top above the two neighboring joists - creating a high point on the floor above.

    Great job, man, esp. the idea of removing a wedge shape off the top ends.
