About the wall doctor
Is this a diagnosis?
No. It is general information to help you describe a problem. A mason should look at it in person.
When should I call an engineer?
For bowing walls, growing cracks and cracks with sticking doors. We will tell you when that is the case.
Is a hairline crack a problem?
Often not, but watch it. A crack that grows needs a closer look.
