In Part 1 of this series, we broke down the factors that influence foundation repair costs. Now, let’s look at the most common repair methods in Los Angeles—complete with real-world examples—so you know what to expect when it’s time to protect your home.

Most Common Foundation Repairs & Price Ranges

Epoxy or Polyurethane Crack Injections

This is often the first line of defense for small cracks in basement or crawl space walls caused by soil settlement. It’s quick, non-invasive, and affordable and usually between $300 and $1,000 per crack.

Example: We recently helped a homeowner in Burbank who noticed a hairline crack in their crawl space wall after heavy rains. They were worried it would cost thousands, but an epoxy injection sealed the crack in one afternoon. It was a small fix that prevented a major headache later.

Carbon Fiber Straps for Added Strength

When cracks start to widen or walls show early signs of bowing, carbon fiber straps can keep the problem from escalating. These straps are bonded with epoxy for strength and cost around $500–$1,000 per strap.

Example: A family in Glendale called us after noticing their basement wall starting to curve inward. We installed five carbon fiber straps for less than $5,000, which was far cheaper than a full wall replacement. They gained peace of mind knowing their wall wouldn’t keep shifting.

Bracing and Anchoring Walls

If you’ve got basement walls that are already leaning or bowing, bracing and anchoring may be required. Steel anchors or braces pull the wall back into alignment and stabilize it permanently. These repairs cost $750 to $1,500 per anchor.

Example: One Los Angeles homeowner ignored early signs of wall movement, and by the time we were called, the wall had shifted significantly. Installing wall anchors corrected the issue without tearing down the entire wall—a huge relief for the homeowner, both structurally and financially.

Slabjacking (Mudjacking or Foam Leveling)

If you have uneven floors because of a sinking slab, slabjacking is a common solution. The process involves pumping grout or polyurethane foam under the slab to lift and level it. Expect $750 to $2,000 per area.

Example: A homeowner in Sherman Oaks noticed their garage floor sloping toward the door. Slabjacking took half a day and saved them from the costly option of replacing the entire garage slab.

Pier Support for Major Settling

When a home’s foundation has sunk unevenly, piers are driven deep into stable soil to lift and stabilize the structure. Costs range from $1,000 to $4,000 per pier, with most homes needing 5 to 15 piers.

Example: A couple in Pasadena had doors sticking and windows cracking. The problem? Severe settling caused by soil movement. We installed eight steel piers, lifting the home back into alignment and preventing future structural problems.

Concrete or Steel Underpinning for Large Homes

For very heavy homes or severe foundation shifts, concrete or steel underpinning is the solution. It’s complex and costly—$5,000 to $100,000, depending on depth and size.

Example: We worked on a large estate in Brentwood where the foundation had shifted nearly two inches. Full underpinning was the only way to stabilize the home, but the result preserved a multimillion-dollar property from catastrophic damage.

Why Not Ask “Cost Per Square Foot”?

You may be tempted to ask, “What’s the cost per square foot for foundation repair in LA?” But as you can see, foundation repairs depend on the type of damage and method used. It’s not a one-size-fits-all number—and anyone who tells you otherwise isn’t giving you the full picture.

(Note: Costs vary based on foundation type, extent of damage, and accessibility.)

When Is a Full Foundation Replacement Required?

While many issues can be fixed with the methods above, a full replacement is sometimes unavoidable:

  • Severe structural failure (large cracks, major shifting)

  • Widespread settlement due to clay soil

  • Old, failing materials (brick, river stone)

  • Extensive water intrusion and erosion
