Foundation Repair questions, answered by experts

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.

Yes. Foundation walls are always load-bearing.

Yes, slab foundations can sink just like any other foundation type. Floating slabs are the most prone to differential settlement and foundation sinking because they sit directly on the surface of the earth. Slab foundations that have footings—including slab-on-grade foundations and monolithic slab foundations—get additional support from soil further down and are less likely to sink over time, especially under larger, heavier structures.

Yes, it is worth repairing concrete cracks. Concrete cracks are normal, and they can be hard to keep from appearing. However, it is worth repairing cracks in concrete for many reasons. For example, it’s possible to repair concrete to the point where the repair is almost invisible. Also, if the crack is left alone, it can become bigger and more expensive to fix over time.
