Foundation Repair questions, answered by experts

Yes. A foundation wall can usually be replaced, but you’ll want to call a foundation professional.

Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor who installs concrete patios to inspect the damage and determine how to fix it.

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.

If you don’t have any access to or knowledge of any area underneath your home, chances are it’s built slab-on-grade. You can also look for the concrete around the bottom edge of your structure; if it’s just a few inches tall, it’s likely a slab. If it’s more than that, has any windows, or you have steps leading to your main entrance, you likely have a different foundation style.

Periodic sealing and cleaning to maintain appearance and integrity.
