Question DetailsAsked on 2/4/2014

How much does it cost to repair a vertical concrete foundation crack?

The crack is wider at the top and narrower at the bottom. The crack is about a half inch wide at the widest spot.

I am presuming you are talking a foundation or foundation wall here. 1/2" wide is pretty wide, and indicates the wall has lost most of its lateral shear integrity - meaning one side could move relative to the other side pretty easily. Most serious if you have a displacement of the two sides relative to each other either front to back (in or out relative to the plane of the wall), and especially if there is a noticeable vertical offset along the crack, which would probably indicate that the footer it also cracked. Also indicates a more serious condition if in a cast concrete wall than in concrete or "cinder" block walls.

I would say this is something that should definitely be looked at by a Structural Engineer, because it is much wider than a normal shrinkage crack. Probably about $250-500 range for a site inspection and evaluation and, if not a severe structural problem, including a remediation recommendation on how to fix it. Up to more like $1000 for a remediation plan probably if a significant structural repair is needed. Repair cost itself, probably by a concrete or grouting contractor or mason (engineer should be able to give you a recommendation), depending on nature of the problem and type of wall, could run from a few hundred $ for injection grouting, to thousands if you have a serious structural failure going on here. No way to tell without detailed onsite inspection, but if no noticeable movement of the two sides relative to each other in the other two directions, commonly (though by no means always) runs less than $1000 for the repair.
