Foundation Cracks

Read foundation cracks before you repair them

Not every crack means a failing foundation, but some do need prompt attention. These guides explain how hairline, vertical, diagonal, stair-step and horizontal cracks differ, what causes them and how to monitor a crack over time. You learn which repairs suit small shrinkage cracks and which signs, such as bowing walls or widening gaps, call for a structural engineer. Understanding the pattern helps you ask better questions and avoid unnecessary work.
