" I heard you had a major buckling problem, Tom."

" Yes, we do. This is our biggest problem over here. Right here inside."

" I can't see it."

" Well, I can feel it with my foot."

" Yeah."

" And here we go. You can see the things. This is rot. Back and forth here."

" Tom, is this the point where the bay window that we're in here? The dining area?"

" That's right."

" Can't relieve yourself beyond this masonry of wall, isn't it?"

" Yes. So I'm assuming that it's a supporting wall underneath."

" Yeah."

" We have closed the building has yet."

" Yes."

" But underneath, it slightly end from what you're looking at right here."

" So the buckling could be structurally caused."

" The building may have settled slightly and this wall did not settle with it."

" Or it could have just been a leak though. You've got radiators that have been here."

" Possibly, yes."

" So how do you fix it?"

" Okay. Right over here, we're going to remove this board. Okay. So Tom has started by drilling here and getting a jigsaw blade and cutting nice and green across the building."

" So that will be the end of the fad."

" That will be the end of the fad."

" And you're just gonna put a cut. Where do you put the cut? Along the joints there or----"

" Well, in some cases, we've been using an old blade and they're drag on to the nail, but that's assuming we use 1 board. We use 1 cut and try and push it down, but as we can see here, we're gonna need at least 3 boards."

" Okay."

" So we're gonna take out the whole board."

" Yeah."

" [unk]."

" Good. So now you've got 1 board ripped it all the way down the middle."

" So now, he's gonna remove that whole board, and here we go."

" And that's the way you do it. Yeah."

" Do you see anything that would indicate what's the cause of the buckling is?"

" Not really, but all I can tell you is that the strip to the sub floor is also up with it."

" Yeah. The sub floor----"

" We're hoping for a gap between and so we could just take it down."

" You know, you could have a situation where the floor joist underneath here don't cantilever across to the end of the [unk]."

" That's correct."

" But this end, it's made through the wall and then they tacked on the extra free [unk] to make a little motion."

" And that [unk]."

" Yeah."

" It bonds through tight."

" Well, it's gonna be a major repair job."

" Pretty mostly, Bob, yeah."

" Okay. Well, we can see in the sub flooring that there is a difference. There's a gap between the boards, and there's a difference in the boards."

" Yeah."

" So it was kind of a structural settling that caused this."

" That's what caused this, Bob, yeah."

" And how many board you gonna have to take out?"

" 3, 4, 5 sides. Whatever it takes."

" We're pulling them out carefully so that we can see----"

" You don't know the damage until you realize it here when [unk] and hope for it."

" Yeah."

" We've taken out 3 of these boards, and as you can see now, we're level here, we're level there. We got to take out the sub floor, which is still the cause of the hump in the floor."

" Sure. Sure."

" Buckle it up. So Tom, have you ever found a situation like this before?"

" I still have not seen. The joist has moved below the level of the [unk] bricks underneath that it's supposing wall."

" And of course, the brick didn't give any at all so that forced the sub floor and the fitted floor."

" That's why the joist settled and the sub floors did not go down with it."

" How do you fix it?"

" I think we'll remove this up close the bricks in."

" Yeah."

" And take a sub floor back unto the joints."

" Yeah."

" And supinate the floor by some help."

" So bang things back down into place."

" Bang them down unto the----"

" We'll finish it from here, and I'll have to make sure that we come in from down below until this is back in."

" Sure."

" Before we install the last board near above, we cut the bottom of the glue as you can see."

" And so you make it easy to get that last piece in. The [unk] is still on that goes into the groove of the adjoining board."

" Just slide in [unk]."

" But now, you can just tap it in. And where we've had a big help, it's all gone."

" That's right."

" Nice job, Tom. Thanks a lot."

" Thank you."
