As soon as a symptom repeats or grows, and routinely at the point of buying or selling. The practical trigger is change rather than presence: almost every house has some cracking, and what separates cosmetic settling from active movement is whether it is still moving. The way to know is to measure — photograph a crack with a dated ruler across it and repeat monthly for three months. A crack that has not changed is usually curing shrinkage. One that widens is structural. Chattanooga's clay soils and hillside lots make the second case more common here than the national average, because clay swells when saturated and contracts in drought, and a house on a slope gets uneven moisture across its footprint. The other trigger worth acting on is any change in how doors and windows operate on one side of the house.
Warning signs you should not wait on: stair-step cracking through brick or block mortar, horizontal cracks in a basement or crawl-space wall, gaps opening where trim meets wall or ceiling, and water entering where it did not before. Act promptly on a crack that is wider than a quarter inch, wider at one end than the other, or that has visibly grown since you first noticed it; doors or windows that have started binding on one side of the house; or a floor you can feel slope. Those indicate movement that is still happening rather than movement that has stopped.
Compare foundation repair companies in Chattanooga on four documents rather than on the sales visit. First, the written scope: pier type, count, spacing, and depth, so two bids describe the same work. Second, the evidence: elevation readings and photos showing what is actually moving. Third, the warranty: what it covers, how long, and whether it transfers to the next owner. Fourth, the drainage plan, because clay soils in this area move with moisture and a structural fix without water control is temporary. Ask every company the same four questions and compare the paperwork, not the pitch. A bid that is materially cheaper is usually cheaper because it contains fewer piers or a shorter warranty. Ask each company how long they have worked in this area and what they do when a repair does not hold, because the answer to the second question is what the warranty actually means.
