Did this contractor just make a big mistake?


We're doing a renovation job in my bathroom, had a guy come in to moe some plumbing around though as we weren't ready to jump that deep into things, here's what the hole they dug into the floor joists (top center of the image) it's roughly 6 inches long and 2 inches deep!

Re: Did this contractor just make a big mistake?


Was that done accidentally when he cut the plywood?

Top notching a joist is not good and needs to be repaired---

What exactly is going on in that photo---is that a bathroom? why is there tile on the wall but no tub or shower?

We're putting a pipe across there, it's in now, I'll post updated pictures in a few minutes.

It's a bathroom, we did the wall tiling first as it was all we could do until we got someone in.

Re: Did this contractor just make a big mistake?


And what's up with all the other holes, crocked cut and that notch in the big hole he cut out?
What type plumbing is he trying to run, drain, supply's?

The whole he cut is roughly 9" long by 2-2&1/2 " deep, the joists are 2x7".

Attached are a few more pictures.

Re: Did this contractor just make a big mistake?


I think that I would take all the subfloor out, sister a new joist on the notched one.

Then start anew with plumbing it the way that your remodel calls for, and then re-floor.

Stop the butchering/ patching/ nonsense.

Calvin,
You've got us all wondering. What exactly is going in that space? Never seen wall tiled from the floor up and the a tub or shower installed after. That notch in the joist does need to be reinforced somehow. That's an awful big notch, especially being I. The top as previous ply mentioned.

We're putting in a free standing tub, we tiled first on the walls because it was the only work we could do before the plumbing was done.

Problem is, where the tub drains, the furnace room is right below and there's a bunch of duct work, so it has to run to that specific spot, there doesn't seem to be many other ways to run this piping.

Re: Did this contractor just make a big mistake?


What's the span of these joist?
Got me worry now with trying to tile a floor with that small a compromised joist, and only a single layer of what looks like plywood.
Where not there to see what your having to work around but in most cases it would have been better to have ran the plumbing through the joist by boring a hole not notching like that, In other cases the joist could have been cut and "headed" off to form sort of a box to make room for the plumbing.
Little late now but as mentioned your trying to do this job backwards which may make a whole lot harder to do it right.

You certainly need to start looking for one. That notch is going to greatly compromise that member. When an inspector comes to inspect the work (this is work being done with a permit isn't it?) he's is going to have a fit about that. Also as mentioned previously you're going to list have to put another layer of plywood on that floor unless you're going to use cement board prior to tiling the floor.

Re: Did this contractor just make a big mistake?


------ Welcome to the forums!-------

Code allows a 1-1/4" max. end notch, AND R502.10;http://premiumaccess.iccsafe.org/doc...de/272/4602731

You could header it off as said as you are within the 3' of bearing without doubling anything or hangers...and still meet code, check local AHJ.

Re: Did this contractor just make a big mistake?


Don't panic yet. Not enough information in this post to even make an educated guess if that notch is a problem. It will depend on the span and how close the notch is to where the joist is supported. A joist compromised in the middle of the span is far more of a concern than one compromised near its support.
