Looks like you had too many “correct” answers Gerry. I am so looking forward to your explanation as to why there really is only one “correct answer”, and which one it is … icon_lol.gif

The question doesn't have anything to do with this particular picture.

Although any crack 1/4" or greater is an indication of a potential problem, horizontal cracks are the most significant sign of structural failure when it comes to basements or foundations.

Gerry, are you gonna just leave us hanging?

Well, I think the “most correct” answer would be a 3/8" horizontal crack … thats a red flag. Any horizontal crack needs a closer look, and I agree that is the most significant crack.


I agree with Jeff in general that any cracks 1/4" or greater needs evaluation, so thats another "correct answer". The 3/16 diagonal crack is also not a "normal" crack, and may really be a concern.

There are many qualifiers that apply, and in some cases cracks 1/8" or greater are a concern, so I am really looking forward to this explanation ... ![icon_wink.gif](upload://ssT9V5t45yjlgXqiFRXL04eXtqw.gif)

Hi to all,


it has been really interesting to read theses comments, and yes there are 2 potentially correct answers, and yes that was quite deliberate ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif)

this is some what of an extreme example of the often made comment that many questions appear to have 2 available correct answers, but that there is always one answer that is the best.

Rob and Jeff, saw through the first answer and read all of the available answers and like many others realized that the last answer was in fact the "best" answer as it mentioned a "horizontal" crack, which is always the biggest red flag that there is.

I agree with all the comments in particular Robs comment that sometimes even a very narrow crack can be indicative of a major problem, for example a crack that is only 1/8 inch wide but that has any lateral displacement would also warrant further evaluation.

By the way, the photograph actually shows a crack that was 3/4 inch at the top, and ran all the way down through the footing, and had a twin on the opposing wall, needless to say it was written up as being in need of further evaluation by an "O'connor" ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif) ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif) ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif)

Like I said before, some times I don't play nice

great comments guys

Regards

Gerry

IMHO, foundation inspections and cracking can be very tricky for an HI, and is also a high liability area where repair costs can be very significant. There is a tendency for an HI to try to evaluate what is going on, which is beyond a home inspection and can be a very slippery slope to be on … icon_wink.gif


You slipped right out of that noose, by admitting there were at least two "correct answers", and possibly more (or all of them) depending on the circumstances ...
