Comparing LA foundation repair bids: scope before price

Best Foundation Repair Companies in Los Angeles: 6 to Compare in 2026

November 11, 2026

Foundation repair bids are hard to compare when they cover different work. One proposal might address the foundation alone, while another adds drainage, a retaining wall or seismic retrofitting. Before you compare prices, it helps to compare scope.

So which are the best foundation repair companies in Los Angeles? This shortlist looks at six, chosen for different project types. Our top pick, listed first, suits complex residential projects where foundation work overlaps with hillside, retaining wall or drainage issues. The others fit more targeted repairs, specific support systems or combined repair and retrofit work.

How We Picked

We compared each company’s published service pages and inspection terms, researched on November 10, 2026. Our criteria were Los Angeles coverage, residential service fit, engineering and construction coordination, repair methods, drainage and retaining wall responsibilities, written findings, inspection charges and warranty scope.

We didn’t inspect properties or test completed work, so this is a service-fit shortlist rather than a workmanship ranking. Whichever companies you contact, follow the California Contractors State License Board’s advice: get at least three written bids based on the same plans, specifications and scope, and don’t automatically accept the lowest.

Los Angeles Foundation Repair Companies at a Glance

1. Alpha Structural

Best for: Homes where foundation work overlaps with hillside, retaining wall or drainage issues.

Alpha Structural has served Los Angeles and Southern California since 1993 and keeps engineering and construction in-house, so one team can design and build a repair. Its services cover foundation underpinning, sister foundations, foundation replacement, caissons and grade beams, hillside and stilt home repairs, retaining walls, hillside drainage and earthquake retrofitting.

Strengths

• In-house engineering and construction under one contract.
• Broad residential scope, from foundations to slopes and drainage.
• Strong hillside and retaining wall focus.
• Says it has inspected more than 15,000 properties.

Watch-outs

• No fixed price list, so budgets depend on a written proposal.
• Confirm assessment terms and the written deliverable for your job.

Proposals: Ask for a written proposal that separates assessment, engineering, construction and any drainage, retaining wall or retrofit work, with responsibility assigned to each part.

2. Saber Foundation & Concrete Repair

Best for: Projects centered on foundation or underfloor support.

Saber lists slab, push and helical piers, described as custom-designed and installed, along with crawlspace support posts and wall-repair products. That gives homeowners named systems to compare when the work focuses on support rather than wider site issues.

Strengths

• Several pier systems to compare.
• Crawlspace support posts and wall-repair products.
• Free quote with on-site inspection and assessment advertised.
• Manufacturer and in-house performance warranties stated.

Watch-outs

• No standard repair price is published.
• Warranty terms depend on the installed system, so don’t assume whole-house coverage.

Proposals: Request both warranty documents and ask which components each one covers.

3. The Foundation Works

Best for: Targeted repairs on an existing home’s foundation.

The Foundation Works lists leveling, crack repair, framing, support enhancement and house-specific spot repairs. It emails a narrative Summary of Findings, typically within 24 to 48 hours, and clearly states which work falls outside its scope.

Strengths

• Focused remedial services for existing homes.
• Written Summary of Findings, typically within 24 to 48 hours.
• Published inspection-fee categories.
• Clear scope boundaries.

Watch-outs

• Refers drainage work to specialists.
• Excludes retaining wall and hardscaping work outside the home’s footprint.

Proposals: Free inspections apply to owner-occupied homes not on the market. Escrow, insurance and investment properties carry fees, so confirm eligibility first.

4. Dalinghaus Foundation Repair

Best for: Homeowners who want clear warranty terms by repair method.

Dalinghaus describes floor-elevation measurements, explained findings and a written estimate during its free Los Angeles evaluation. Its warranty page separates stabilization from lifting, which gives you a precise question to ask about any proposed method.

Strengths

• Floor-elevation measurements during the evaluation.
• Written estimate from the visit.
• Warranty explained method by method.
• Free, no-obligation evaluation advertised.

Watch-outs

• Pier warranties cover stabilization, not a guaranteed lift.
• Coverage varies by installed method.

Proposals: For crawlspace jacks, Dalinghaus separates five-year stabilization coverage from a 25-year manufacturer warranty. Ask who handles each type of claim.

5. Sunshine Foundation Repairs

Best for: Slab and raised-foundation homes.

Sunshine describes an inspection-first approach for slab and raised foundations in Los Angeles and surrounding areas. Its services include concrete and steel underpinning, stabilization, lifting, structural support, helical piers, foundation replacement and slab replacement.

Strengths

• Covers both slab and raised foundations.
• Wide method range, from underpinning to replacement.
• Inspection-first approach.
• Free homeowner inspections advertised.

Watch-outs

• Escrow inspections carry a fee, with no amount stated.
• No property-specific pricing is published.

Proposals: Ask Sunshine to explain the findings behind its recommended method and how the written scope addresses them.

6. Golden Retrofit & Foundation Repair

Best for: Homes needing foundation repair and seismic retrofitting together.

Golden states a residential foundation and retrofit focus. Its repair scopes include slab leveling, pier-and-post support and foundation leveling, while its retrofit services cover foundation bolting, cripple-wall bracing and shear-wall installation, with permit coordination when required.

Strengths

• Repair and retrofit from one company.
• Bolting, bracing and shear-wall installation.
• Permit coordination advertised.
• Free consultation offered.

Watch-outs

• Repair and retrofit are different scopes, so proposals need to separate them.
• No fixed price is published.

Proposals: Ask for repair items and retrofit items to be listed separately, with permit responsibilities and exclusions.

How to Compare Foundation Repair Proposals

Match the Scope First

Line up what each proposal includes before looking at totals. A lower price may simply leave out drainage, a retaining wall or retrofit work that another bid includes. For a deeper look at why some repairs need engineering input, this guide to advanced engineering fixes for foundation and crawl space problems explains when soil analysis and load calculations matter.

Check Who Is Responsible for What

Ask each company who designs the repair, who builds it and who handles permits. Where several contractors are involved, make sure each one’s responsibilities are written down.

Read the Warranty for Each Method

Warranties often differ by repair method and component. Ask what result is covered, such as stabilization or lifting, and who handles a claim.

Verify Licensing and Insurance

A license number on a website doesn’t confirm current status. Check the contractor’s record with the CSLB and request insurance documentation before signing.

Conclusion

The best foundation repair company in Los Angeles depends on what your project involves. For complex homes where foundation work overlaps with hillside, retaining wall or drainage issues, the first company on this list offers the widest coordinated scope. Saber suits pier and crawlspace support projects, The Foundation Works fits targeted repairs, Dalinghaus offers clear method-specific warranties, Sunshine covers slab and raised foundations, and Golden combines repair with retrofit work.

Choose three companies that match your scope, request written proposals based on the same plans and specifications, and confirm inspection charges, licensing and insurance before you hire. If proposals disagree significantly about the problem, an independent engineering opinion can help you decide.
