The timeline for a foundation repair project depends on the complexity of the work. Simple jobs like sealing a small crack can often be completed in just a few hours. More involved repairs, such as stabilizing bowed or leaning walls, may take a few days. That said, it's rare for even our largest projects to take longer than a week. We'll always give you a clear timeline up front so you know what to expect.

There are a few common signs to watch for. Inside your home, look for cracks in walls (especially above doors or windows), sticking doors or windows, or sloping floors. Outside, you might see cracks in the foundation itself or walls that appear to bow or lean. That said, not all cracks mean major trouble. The best way to know for sure is to schedule a professional inspection. At Jet Foundation Repair, we’ll give you an honest assessment and let you know if it’s something urgent—or something to simply keep an eye on for now. No pressure, just clear info so you can make an informed decision.

In St. Louis, foundation problems are most often caused by the region’s expansive clay soil, which swells when wet and shrinks during dry spells. This constant movement puts pressure on your foundation, leading to cracks, settling, or bowing walls over time. Heavy rainfall, poor drainage, and extreme seasonal changes can make things worse. Older homes without modern waterproofing are especially vulnerable. At Jet Foundation Repair, we understand the unique soil and weather conditions in the St. Louis area—and we design repair solutions built to last in this environment.
