Slab Foundation Repair in Los Angeles
Fix cracked, sinking, and uneven concrete slabs with licensed slab foundation repair experts (Lic. #1092628) serving Los Angeles and surrounding areas.
Expert Slab Foundation Repair Across Los Angeles
A concrete slab is only as stable as the soil beneath it. When that soil swells, shrinks, or washes away, the slab cracks, sinks, or lifts — and you see it in your floors, walls, and doors. We repair the slab and fix the conditions underneath so the damage stops. It’s a core part of our complete foundation repair services for homeowners across the LA area.
Signs Your Slab Foundation Needs Repair
Slab problems show up throughout the house, not just in the concrete. If you see several of these, it’s worth a professional look.
- Cracks in the slab or floor tile
- Uneven, sloping, or sinking floors
- Doors and windows that stick or won’t latch
- Cracks in drywall, especially at corners
- Gaps between walls, floors, and the ceiling
- Warm or damp spots that hint at a slab leak
What Causes Slab Foundation Problems in LA
Slab damage almost always starts in the soil. We identify the cause so the repair actually holds.
- Expansive clay soil that swells and shrinks
- Poorly compacted fill beneath the slab
- Plumbing and slab leaks washing out soil
- Poor drainage and moisture around the home
- Drought cycles drying and shrinking the soil
- Tree roots drawing moisture from under the slab
How We Repair Slab Foundations
We match the repair to the slab and the soil beneath it — lifting, stabilizing, and sealing so the floor is solid and level again.
- Slab jacking — pump slurry under the slab to raise it
- Polyurethane foam — precise, lightweight slab lifting
- Slab piers — deep support for heavily settled slabs
- Crack repair — seal and bond cracks in the concrete
- Leak coordination — fix plumbing leaks under the slab
- Drainage correction — stop the water that caused it
Slab Foundation Repair Methods Explained
The right method depends on how far the slab has moved and why. Here are the proven slab repairs we use across Los Angeles homes.
- Slab jacking (mudjacking) — pumps a cement slurry beneath a sunken slab to lift it back to level.
- Polyurethane foam injection — injects expanding foam that lifts slabs precisely with minimal mess.
- Slab piers — steel piers driven to stable soil to support and lift heavily settled slabs.
- Epoxy crack injection — structurally bonds and seals cracks in the slab.
- Plumbing leak coordination — locate and repair under-slab leaks that wash out soil.
- Drainage correction — fix the water and soil problems that caused the movement.

Slab Foundation Repair FAQs
How much does slab foundation repair cost in Los Angeles?
It depends on the method and how far the slab has settled. Minor slab jacking or foam leveling often runs about $1,500 to $6,000, while slab pier installation on a significantly settled foundation can range from roughly $10,000 to $25,000 or more. We provide a free on-site inspection and a clear, written, fixed-price quote before any work begins.
What are the signs of slab foundation problems?
Common signs include cracks in the slab or floor tile, uneven or sloping floors, doors and windows that stick, drywall cracks at corners, and gaps between walls and floors. Warm or damp spots on the floor can also indicate a slab leak that’s undermining the foundation.
What is the difference between slab and pier-and-beam repair?
A slab foundation is a single concrete pad poured on the ground, while a pier-and-beam foundation is raised on supports over a crawl space. Slabs are repaired with slab jacking, foam, or slab piers; pier-and-beam homes are repaired by replacing piers and beams and re-leveling. We work on both.
How long does slab foundation repair last?
When the soil and drainage causes are addressed, slab repairs are long-lasting. Foam and slab jacking are very durable, and slab piers provide permanent support because they reach stable, load-bearing soil. We back our work with a workmanship warranty.
Is polyurethane foam or mudjacking better for lifting a slab?
Both work well. Mudjacking (slab jacking) pumps a cement slurry and is economical for larger areas, while polyurethane foam is lighter, cures fast, and allows very precise lifting with smaller holes. We’ll recommend the best option for your slab after inspecting it.
Can a plumbing leak cause slab foundation damage?
Yes. A leak under the slab can wash out the soil that supports it, leading to sinking and cracks. That’s why our inspection includes checking for slab leaks — we coordinate the leak repair and then lift and stabilize the slab.
How long does slab foundation repair take?
Most slab jacking and foam repairs are completed in a single day. Slab pier installation on a heavily settled foundation can take a few days. We’ll give you an exact timeline with your quote.
Is slab foundation damage covered by insurance?
Usually not. Most policies exclude damage from gradual settling, soil movement, and poor drainage, though sudden damage from a covered event such as a burst pipe may be covered. We’ll document the cause to help with any claim, but always confirm with your insurer.
