Are there any rules of thumb for repairing floor joists that are excessively notched?
I have the typical situation where the plumber came in any notched the top of a 2×10 floor joist beyond what will be accepted by the inspector.
I would like to repair with 1/2″ cdx plywood glued and nail (1 side or 2). For a 4″x5″ notch, how big should the plywood plate be and what should the nailing pattern be?
Thanks for the help

2x10 unless it is an old joist it is 1 1/2 by 9 1/2 any notch 5 inches has destoyed the joist. The so-called plumber should be responsible!!. If you can't get him to fix it you have to ask the inspector what he requires. Sorry for a negative. Lots of luck.
"If all else fails, read the directions"
you're exactly right. When I wrote this, I wasn't thinking about the actual size of the notch. It is more than 1/2 the joist height!!! Aack!
time to regroup
thanks for the wake up call.
Your plumber sounds like a cartoon character...the kind that sits on a branch while sawing it...but not sitting on the trunk side.
This is wrong?
Even though a lot of posts have come up with good ideas, which I've used myself. If you have a inspector involved he should tell you what HE will approve, thats the bottom line. "May the force be with you".
Thank you - I have enjoyed reading all of the discussion.
I am in the process of gettng the BI involved, so that I know his requirements.
LUCK!
If I remember correctly, a notch, hole (whatever) can be no bigger than 1/3 the height of the joist. This 'rule-of-thumb' does not apply to engineered joists.
In your situation, assuming the offending plumber is long gone, I would sister new joists on both sides, if possible. Don't go crazy here. Look at the span that might be be impacted by the large waste pipe cuts and cut the new joist lengths accordingly.
HTH
What you do here is to cut the plumbers waste line off, sister in a new joist, and then let him drill his new hole as it should have been done instead of notching

Man, I don't know why I never thought of that, but I'm doing it next time. Absolutely beautiful. <G>
When we worked commercial in a new mall we saw a variation of "cut the waste line".
Nite work in the food court area.......................
Electrician would run his conduit during regular business hours.
Moonlight plumber would cut out the pipe and run his lines.
Next morning-piss'd off electrode would cut the plumbers work and run his again.
This went on for two days till the Mall hired us out to run new additional walls between the spaces.
Tad bit of lack 'o communication that was.A great place for Information, Comraderie, and a sucker punch.

I alwayss try to have the plumber do his work first, becaue electricians generally get more options. Sparks can flow uphill

Yes.
In this situation the mall didn't use the foresight to provide two separate common walls (thought 8'' was enough for the common wall) and several different food shop owners were the ones hiring the subs.
Comical to watch tho.A great place for Information, Comraderie, and a sucker punch.

Joe, if you have an opinion you should not be shy about expressing it. Let us know what you really think. <BG>
That was good.
