Contractor drilled into sistered joists


My house is a Cape & the walls on either side of the stairwell are load bearing walls
Any work completed in my house by a contractor they do not get paid until they pass my inspection

And if they drilled the joists in my house like that they'd be replacing the joists at their cost

If you don't want a post then sistering in another is an option
I don't think it will be easy with wires & gas line (?) there

The supply line you see is the baseboard heat. A sister joist would just clear it but good luck sliding a joist in such a tight spot. The post still seems like the best approach. Any input as to what material?

Hind sight is 20/20. I wish I had looked under the floor when he was done.

I don't think this joist is under a load bearing wall, thank goodness.

Got to sign off for the weekend. Thank you everyone!!

Depending on the anticipated load, I've seen engineered repairs for conditions similar to this that incorporate bolting angle stock (1-1/2"x1-1/2"x1/4") to the side and bottom of each joist, using a pre-defined bolting pattern. I would agree that the capacity of those joists (especially the left one) has been reduced significantly.

The reason I don't think it's that big of an issue is the header is only 36-40". Yes it supports the stairs but it's a double 2x10 and it's close to the bearing surface. With that said.. Would I have done that? absolutely not.
You could add strapping like #5 in this article with the strapping crossover directly under the hole.

If you were to tear up the floor in your bathroom, I bet you would find things that would concern you much more than this.

Good luck and follow up with what you ended up deciding to do.

I don't think the concern is any load coming in off that header. The concern is the wall above that's in line with the drilled joists. Also, the stringer for the stairs above is bearing on those joists as well.

If you don't have a problem with a post - it would be easy to install a jack post under there. May or may not help with your stair creaking...

Google jack post and you will find this and seveal similar: http://www.tigerbrandjackpost.com/

I would have that contractor back at my house to replace that, at their cost....

But if that didn't work out and it were my house... I would remove the wiring going through and sisters and attach a 3rd joist to the left (as close as possible to the full length of the compromised joists), with constuction adhesive and lag bolts (stagger the lags, and double them up on each side of the weak area). While there's definitely a structural impact, I don't believe you need to go to the expense of a structural engineer. This fix would save you having a post in your way.

Speaking of posts... In most areas jack posts, as per the above website, are not allowed for perminent use. If you go to that website, you would want one of the 2 bottom options.

I have no problems doing framing or electrical, don't attempt this if you're not comfortable with these areas.

You have all confirmed my concerns that I need to address this issue. I think the ideal solution is to sister a third joist. A post is probably the easiest solution but my concern is that it could be construed as a patch and not the best cure.

I am not confident in tackling this one by myself. Wish me luck with the next contractor. They aren't always so reliable around here if you can even get them to show up. I wish there was a way to certify them so that you could be assured that they will do the best job possible. But that's another topic for another day. At least now I have the information on what needs to be done and how it should be accomplished. Thank you everyone! Mel

We are in Philadelphia. We have lots of friends who have similar stories to ours. It's gotten to the point where we feel like we have to study up on proper techniques and materials in order to insure that the job is done right.

One friend recommended Service Magic as a type of precertification that they had good luck with out in Bucks County. But our first encounter with some of the contractors here raised some serious red flags immediately.

It's difficult around here to find someone who wants to do the job let alone do it correctly or own up to and correct mistakes. But we have found a few folks who have been great and done the job right the first time. We are happy to recommend them to others and spread the word to our friends. It's been interesting to say the least.
