At some point in the process, this “plumber” must have known he was in over his head, but he didn’t stop. Is this happening more often, or does the Internet just shine more light on an old problem? Here’s a pretty glairing reminder to do a little checking before you hire a plumber or any other contractor. And if you don’t have your own DIY knowledge to fill in the gaps, to the Forum and they’ll tell you what you need to know.

Original Post: Plumber cut exterior concrete block support wall for 2 1/2 drain pipe.

Hi, I know nothing about plumbing or concrete block construction. I am doing a low cost remodel and am new to Florida. I don't know if I can trust this plumber's advice that the section of concrete block that he cut will not impact the structure.

He was going to cut into the concrete slab, but at the last minute, he cut through the wall. I'm concerned that it has impacted the soundness of the structure. No rebar was in what he cut and the blocks he cut through were hollow. Any input would be greatly appreciated.

This guy needs to go now. What's he expect, that foam to hold up the house?

I would far rather have a bump out to house all the plumbing than have my wall jeopardized as he has done. He needs to return and repair the wall with concrete, not spongy foam sealant. You have a definite problem with stability. If he can't fix it (and most plumbers can't) he needs to pull that plumbing out of the lateral part of that wall and mount it on the outside and hire a concrete mason to repair the wall on his dime. Not acceptable.

Who's idea was it to cut the block? The plumber should have known better! As Larry said, the wall should have been built out to accommodate the drain pipe. The rebar is in the footer and probably the corners (vertically).

btw - welcome to the forums Rick!

Wait, you're saying he actually cut all the way through the cinderblock? I have seen plenty of hollow cinderblock construction in the interior but it doesn’t actually cut all the way through the cinderblock.

You're in Florida and you have no insulation or anything in between the drywall and cinderblock? That's weird to me.

I believe only one side of the block is cut but that still dramatically reduces its strength.
The insulation is installed between the furring strips and then a vapor barrier over the entire wall.
