Check out this deck joists- it’s completely rotten where there was a knot, and the one next to it sagged like crazy.
It’s literally down an inch and a quarter in the middle.
The house is 20 years old, and this type of decking is no longer made.
So, I wanted to replace the bad joist without removing any decking.
We removed all the old square head deck screws above the bad joists.
20 years ago, we used these galvanized spiral nails instead of deck screws.
They’re almost impossible to pull out, so I cut them all with my Sawzall -first at the ledger board, then over the beam, and finally out at the rim board.
Cutting the joists in half made them easier to tear out.
I did a thorough inspection of this deck and everything else was in good shape.
When you install joists it’s important to put the crown up.
We definitely had to use some persuasion to get the new ones in- I like to think “most of life’s problems can be solved with a bigger hammer”.
Back when this deck was built, joist tape wasn’t a thing. Since the homeowners are planning to replace the entire deck in the next five years, we didn’t use it on the ones we replaced.
I love using these joist hanger screws- they’re so much faster than pounding in nails.
Once the hangers were installed, we screwed the deck boards back down using the same holes.
These torque head screws work so much better than the old square head screws.
