Floor Joist No Sill Plate

We worked for a builder about ten years ago that did something similar.

Floor joist no sill plate. Sill plate repair replacement. As i started to shopvac the cavities last night i noticed that there is no sill plate. I spent the last few days replacing a rotten sill plate the horizontal piece of wood that lies between the foundation and the floor joists. Said job leads to the following all caps admonition.

The floor supports did not look pressure treated but maybe the way they used to do things made this ok or the type of lumber that was used was more resistant to rot. Secure the new rim joist with 16p nails. A sill plate or mudsill is the bottom horizontal member of a floor system to which vertical members floor joists are attached sill plates are usually composed of lumber in sizes of 2 4 2 6 2 8 and 2 10. If you have noticed that all of the floors in your home are sloping towards the center of the house this indicates there s something wrong with the main.

The floor joists and rim joists rest directly on the block wall. Please for the love of god do not pour a concrete patio above the level of your foundation. How to open a garage door with a broken spring. Just the block cavities open to the conditioned space.

The ends of the floor joists rest on the sill plate while the center of the joists rest on the main beam. It was 2x10 joists but no mudsill just sill seal. You can remove the rotted wood and cut new sections to replace the old one. After the house was framed we would go in the basement and nail 2x4 s up on the bottom of the joists tight against the inside of the foundation.

I had never seen this before but it appeared to be causing no issues. There is no vapor barrier or covering of any type over the top of the block wall. Guess they never heard of uplift. You don t need to use galvanized nails here.

I don t see any evidence of rot on the joists.
