Hire a foundation specialist for structural crack assessment

When cracks are wider than 1/4 inch, horizontal, stair-stepping, or actively growing, DIY sealant is not sufficient. A foundation specialist determines whether the damage is cosmetic or structural and recommends the appropriate repair.

When to Call a Pro

• Horizontal cracks in block or poured walls (indicates lateral soil pressure)
• Stair-step cracks in brick or block (indicates differential settling)
• Cracks wider than 1/4 inch or growing year over year
• Doors or windows that suddenly stick or won't close
• Visible wall bowing or leaning
• Water intrusion through foundation walls

What to Expect

• Inspection: $300-$500 for a structural engineer's assessment (some foundation repair companies offer free inspections but may upsell)
• Epoxy crack injection: $500-$2,000 per crack — seals and structurally bonds the concrete
• Carbon fiber reinforcement: $1,000-$3,000 per wall — stabilizes bowing walls without excavation
• Helical or push pier underpinning: $1,000-$3,000 per pier — for homes with settlement issues
• Average foundation repair: $5,172 nationally (range $2,200-$8,100)
• Severe cases: $15,000-$30,000+

Tips

• Get 2-3 quotes from foundation specialists, not general contractors
• Ask for a transferable warranty — it protects resale value
• Catching structural problems early keeps repairs in the $500-$2,000 range instead of $15,000+
