The video demonstrates how to install a double floor joist beam as a part of structural home repairs. Greg mentions that while this method might not be approved by an engineer, it could be a very effective way to make this type of repair. He also notes that the video is meant for people who are comfortable with DIY projects and are not looking for a professional solution.
Here are some of the key points from the video:
The video focuses on repairing a wall that is not supported by a double-double type of floor joist or a beam.
The speaker suggests using a slightly smaller beam than the floor joists. For example, if you have 2x10 floor joists, you could use a 6x8 beam.
The smaller beam will create a 2-inch space between the beam and the floor joists. This space can be helpful if you have a sagging floor.
You can shape your own beam by cutting a piece of wood to the desired size.
The speaker recommends using a wider beam, such as a 6x8, to support the weight of the wall and the roof.
After positioning the beam, you will need to jack it up into place. You can use a post and a jack to do this.
Once the beam is in place, you can slide block-shaped pieces of wood underneath it to support it.
The speaker emphasizes that he is not a structural engineer and that these are just ideas that he has found to be effective. He encourages viewers to consult with a professional if they are not comfortable with the information in the video.
Here are some bonus tips and assembly/design ideas from the video:
If the other room has drywall in it, you can slide the beam further into the room to set it on top of the other wall. This will allow you to use a longer beam.
You can use a single jack to jack up the beam into place. However, it is recommended to use two jacks if you have a long beam.
You can use a variety of materials for the block-shaped pieces of wood that you slide underneath the beam. For example, you could use 2x4s, plywood, or 4x4s.
Greg recommends using a wider beam than the minimum required by the building code. This will help to ensure that the beam is able to support the weight of the wall and the roof.
