"Tyrell did an excellent job correcting the mistakeS of the people who installed my basement waterproofing equipment. There was a terrible rotten egg smell and that's gone now. Tyrell cleaned up after himself, if any water spilled he made sure to vacuum it up and to dispose of everything in the proper place."

Foundation Repair questions, answered by experts

Barring extreme home foundation problems, most horizontal foundation cracks are fixable using one or more methods. Most of the repair methods require professional expertise to accomplish, and include plate anchors, steel reinforcement, soil anchors, reconstruction, or carbon fiber strip applications. Contacting a professional to diagnose the problem early can minimize repair expenses.

Whether or not repairing your foundation is worth it before selling depends on the extent of the damage, the cost of the foundation repair, and your timeline for relocating. If the damage is major or structural in nature, chances are you’ll sell at a higher price if you take care of the problem beforehand. You should consider the cost of the repair first, though, as laying out thousands might not be possible with your budget. Additionally, if you’re in a rush to relocate, you might want to repair before selling so as not to limit your buyer pool.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.

Cracks, shifting, or uneven floors indicate potential foundation issues.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.
