Serious vs. Minor Foundation Problems

Not all cracks indicate structural problems. Often non-structural: Hairline vertical cracks (normal concrete shrinkage), small cracks that aren't growing, cracks only in surface coating. Potentially structural: Horizontal cracks in block or poured walls (indicates lateral soil pressure), stair-step cracks in brick/block, cracks wider than 1/4 inch, cracks that are growing or displacing (one side higher than the other), bowing or leaning walls.

Getting a Foundation Assessment

Get 2–3 quotes from foundation specialists. Be skeptical of companies that only quote their proprietary systems — some foundation contractors oversell expensive repairs. A structural engineer's independent assessment ($300–$700) is worth the cost before committing to major repair work — it gives you an objective evaluation you can take to multiple contractors for bids.

Frequently Asked Questions

Should I buy a house with foundation problems?

It depends on the type and severity. Minor cracks are often non-issues. Structural problems (settled foundation, bowing walls) require careful evaluation — get a structural engineer's report and multiple contractor bids before closing. Factor repair costs into purchase offer. Some foundation issues are genuinely manageable; others are serious enough to walk away.

Does homeowner's insurance cover foundation repair?

Standard homeowner's insurance typically does not cover foundation damage from settling, soil movement, or normal wear. It may cover sudden, accidental events (like a burst pipe damaging the foundation). Flood damage (requires separate flood insurance) and earthquake damage (requires separate earthquake coverage) are also excluded from standard policies.
