Retaining wall repair FAQs

Can a retaining wall be repaired?

Yes, a retaining wall can be repaired. Repairs are much more cost-effective and practical than removing the wall and building a new one.

Have the wall inspected regularly for structural issues so repairs can be made promptly. Ignoring or overlooking a small problem can cause it to turn into a huge one, drastically increasing costs or leading to the need for a complete replacement.

Who can fix a retaining wall?

Masons and landscapers can fix or build a retaining wall. Before making repairs to a wall that is leaning or bowing, consider hiring a structural engineer to determine the underlying cause of the problem.

Can I repair a retaining wall myself?

Yes, it is possible to repair a retaining wall yourself, depending on the extent of the damage and your own experience.

Have an expert examine the wall to determine the issue before deciding if it is a problem you can fix yourself. Inadequate repairs can lead to more substantial problems, which will cost more in the long run.

Do I need a permit to repair a retaining wall?

No, you typically do not need a permit to repair a retaining wall. Most cities require a permit when building a new retaining wall over four feet; however, repairs do not necessarily warrant one. If the repairs drastically change the wall's footprint, height, or structure, you might need a permit.
