"Is this problem structural or cosmetic?"

Why it matters: Most foundation cracks are cosmetic: small hairline cracks in poured concrete, vertical cracks less than 1/4 inch wide, cracks that have not changed in years. Structural concerns include: horizontal cracks in block foundations, cracks wider than 1/4 inch, cracks that are actively growing, stair-step cracks in block or brick, and bowing or leaning walls.

"Is this problem actively moving or has it stabilized?"

Why it matters: A crack that formed decades ago during initial settlement and has not changed is very different from a crack that is actively widening. Active movement requires different treatment than a stabilized old crack.

"What is causing this problem, and have you addressed the root cause?"

Why it matters: Many foundation problems are caused by drainage issues: water accumulating against the foundation, downspouts discharging against the house, grading that slopes toward the foundation. Repairing the foundation without fixing the drainage means the problem comes back.

"Do I need a structural engineer's evaluation?"

Why it matters: For any significant foundation concern, a licensed structural engineer (not an employee of the foundation repair company) can give you an independent assessment of what is wrong and what is required. This typically costs $300-$800 and can save you from an unnecessary $15,000 repair.

"What exactly will this repair accomplish?"

Why it matters: Foundation repair claims can be vague: "stabilize your foundation," "prevent further movement," "restore your foundation." Ask specifically: what will be different after this repair, what will not be fixed, and what are the limits of the repair.

"Do you use company employees or subcontractors?"

Why it matters: Foundation repair requires skilled installation. Subcontractors can be experienced, but ask about training and quality control.

"What is your warranty, and does it transfer with the home sale?"

Why it matters: Foundation warranties are a major selling point for many companies. Read the warranty carefully: what triggers a warranty claim, what is excluded (typically "acts of God," tree root damage, continued drainage problems), and whether it transfers to future homeowners.

"Are you licensed, insured, and do you pull permits?"

Why it matters: Foundation work is structural. It requires licensed contractors in most states and permits in most jurisdictions.

"What does the repair look like from inside and outside after completion?"

Why it matters: Some foundation repairs leave visible hardware inside the basement. Crack injections fill cracks but do not remove them.

"What drainage or grading improvements should I make alongside this repair?"

Why it matters: A good foundation contractor will tell you what else needs to happen for the repair to be effective long-term. If they only talk about what they are selling, ask directly.

"How long will this repair take, and what does my home look like during the process?"

Why it matters: Foundation repairs can require excavating around the exterior, removing floor sections in the basement, or making interior spaces inaccessible during work..

"What is the payment schedule?"

Why it matters: For major foundation work, a deposit at signing, progress payments at milestones, and a final payment on completion is standard..
