Crack shape matters more than fear factor
A stable vertical shrinkage crack can be a sealing job. Horizontal cracks, stair-step cracks with movement, widening gaps or bowing walls can point to a different structural problem and a very different budget.
Injection price is not a structural diagnosis
Epoxy or polyurethane can seal a crack, but a contractor should explain why the crack formed and whether movement is active. RepairGauge does not treat every visible crack as a simple injection.
What to document before calling anyone
Photograph the crack with a ruler, note orientation and width, look for matching movement elsewhere, and record whether water enters. That makes follow-up comparisons much more useful.
