  "tldr": "Rule one: for anything possibly structural, the structural engineer comes before the contractor — $300–$600 buys a diagnosis from someone with nothing to sell, against a repair that averages $5,200. Hairline vertical cracks in drywall or concrete are usually settling and cosmetic. The engineer-first list: stair-step cracks in block or brick, horizontal cracks in foundation walls, doors and windows that stopped closing, sloping floors, and any crack that keeps widening.",

  "faq": [
    {
      "q": "How do I know if a wall is load-bearing before removing it?",
      "a": "You don't — that's the point of the question. Rules of thumb (perpendicular to joists, center of the house, stacked over a beam or wall below) are how homeowners guess, and guessing wrong is catastrophic. A structural engineer answers it definitively for a few hundred dollars and specifies the beam if you do remove it; the permit office will want that stamp anyway."
    },
    {
      "q": "Which cracks are normal and which aren't?",
      "a": "Usually normal: hairline vertical cracks at drywall seams, above doors and windows, and fine vertical shrinkage cracks in poured concrete — houses settle and materials shrink. Escalate when the pattern changes: stair-step cracking through block or brick joints, horizontal cracks in a foundation wall (soil pressure), cracks wider than about a quarter inch, cracks with offset (one side proud of the other), or any crack that visibly grows between photos."
    },
    {
      "q": "Why not just get a free foundation company inspection?",
      "a": "Because the free inspection is a sales visit. Foundation companies sell pier and stabilization systems; their inspectors are commissioned on what they find. Sometimes the finding is real — but you can't tell from inside the sales pitch. The engineer's few hundred dollars buys the version with no product attached, and contractors then bid against the engineer's scope instead of writing their own."
    },
    {
      "q": "Should I worry about a sinkhole?",
      "a": "Odds are low outside karst geology (Florida, and pockets of Texas, Tennessee, Kentucky, Missouri, Pennsylvania). Warning patterns worth a call: circular or radiating cracks, a ground depression that appears or deepens, fence posts or trees tilting together, doors popping open. In those states, insurers offer (and sometimes must offer) sinkhole or catastrophic ground collapse coverage — call your insurer and your state geological survey rather than a contractor first."
    },
    {
      "q": "The house is settling — is that automatically covered by insurance?",
      "a": "Almost never. Settling, shrinking, and soil movement are standard homeowners exclusions — the policies cover sudden events, not gradual movement. That's the same sudden-vs-gradual logic as water claims. The exceptions are the specific add-ons: sinkhole coverage where offered, and earthquake policies. One more reason the engineer's report matters: it documents cause."
