How to Find a Foundation Repair Contractor

Foundation repair is one of the most consequential — and most variable — home services. A $25,000 piering job on a 6-pier home from one contractor can quote at $42,000 from another. Both can be legitimate quotes for different spec (push pier vs helical pier, depth, install method). And in foundation work specifically, getting it wrong is expensive: a poorly stabilized foundation needs to be redone, often costing more than the original repair. This guide walks through how to actually vet a foundation repair contractor and how to compare quotes the right way.

Why foundation work is different from other home repairs

Foundation repair is the only residential trade where the diagnosis is often more important than the repair. Two contractors can look at the same crack and propose:

• Crack injection ($800-$2,500)
• Carbon-fiber stitch ($1,500-$3,000 per crack)
• Wall anchors ($600-$900 per anchor)
• Push piers ($1,500-$2,500 per pier)
• Helical piers ($1,800-$3,200 per pier)
• Slab piers ($1,200-$2,000 per pier)

Each is right for a specific failure mode. The single most important thing you can do is have a structural engineer (separate from the contractor) inspect the home and write a scope before you compare quotes. Engineer inspection costs $400-$1,200 and saves homeowners 5-10x that on average by ensuring contractors quote the right repair.

Get an independent structural engineer first

A structural engineer is not a foundation repair contractor. They’re a licensed PE who:

• Inspects the home
• Identifies the failure mode (settlement, hydrostatic pressure, expansive soil, sinkhole, etc.)
• Recommends the appropriate repair method
• Writes a sealed report you can give to contractors

The benefit: contractors quote on the same scope. Without it, each contractor proposes whatever they sell, and you can’t compare.

Many foundation contractors offer “free engineering inspections” — these are sales tools, not independent diagnostics. Pay $400-$1,200 for an actual independent PE before getting repair quotes.

What “good” looks like in a foundation contractor

After the engineer’s report, the signals that correlate with a quality install:

1. State contractor’s license with foundation/structural classification
2. Engineer-on-staff or partnered engineer for the install design
3. Manufacturer-certified pier installation — companies like Earth Contact Products (ECP), Atlas Systems, and Foundation Supportworks have certification programs
4. Lifetime transferable warranty on piers — this is industry standard for piering work
5. General liability + workers comp — $1M/$2M minimum
6. 5+ years specifically in foundation work — distinct from waterproofing or general construction
7. Itemized quote matching the engineer’s scope
8. References from 2-3 jobs they’ve done in the last year within 25 miles

What to look for in a foundation repair quote

A real itemized quote in 2026 should break out:

• Pier type — push pier, helical pier, slab pier (engineer should specify)
• Per-pier cost — typically $1,500-$3,200 installed in 2026
• Pier depth target — depth to load-bearing strata
• Number of piers — based on engineer’s analysis
• Excavation and backfill
• Any wall anchoring or stitching (for bowing walls)
• Crack injection if applicable
• Drainage fixes (sump pump, French drain, regrading) — often the actual root cause
• Restoration (concrete patching, landscaping)
• Permits — typically pulled by the contractor
• Engineer’s stamped post-repair certification — required for resale disclosure

A flat “we’ll fix your foundation for $X” without a breakdown leaves you with no way to compare quotes or hold the contractor to spec.

Red flags

What we hear most often:

• No structural engineer involved at all — sales-driven contractors sometimes skip this. Walk.
• Pressure to commit during the home visit — real foundation work involves engineering review and 1-2 weeks of quote turnaround.
• “Lifetime warranty” without manufacturer backing — make sure the warranty is from the pier manufacturer (ECP, Atlas, etc.), not just from the contractor’s company. Contractor companies fail; manufacturer warranties survive.
• Cash-only or significant deposit upfront — $0-25% deposit is normal; 50%+ is a red flag.
• No mention of permits — foundation work always requires a permit and inspection.
• Quote varies wildly from engineer’s scope — if the contractor proposes a totally different approach than the engineer recommended, get a second opinion before signing.
• Drainage not addressed — most foundation problems are caused by water management. A piering quote that doesn’t fix the underlying drainage will see the home settle again.

Questions to ask before signing

1. License number + insurance COI in writing
2. How many homes have you piered in the last 12 months? (Should be at least 20)
3. Is your installer factory-certified by the pier manufacturer?
4. Can I see the engineer’s stamped install design?
5. Lifetime transferable warranty — is it from your company or from the pier manufacturer?
6. Will you provide a stamped post-repair engineer’s certification?
7. Who pulls permits?
8. What’s the timeline (typically 2-4 days for residential piering)?
9. References from 3 jobs within 25 miles in the last year

How to compare 3 foundation quotes

After you have the engineer’s scope:

1. Take the engineer’s report to 3 foundation contractors
2. Ask each to quote against that exact scope — same pier type, same depth, same count
3. Compare on price, warranty source, install timeline, and certification level

For foundation work specifically, the cheapest quote is rarely the right one. The questions above weed out the discount installers who’ll leave you with re-do problems in 2-5 years.
