Foundation Repair Reviews: How to Actually Verify a Contractor

Quick Answer

Online reviews alone are not sufficient to verify a foundation repair contractor — you need to cross-reference reviews with license verification, insurance confirmation, and complaint history through your state licensing board and the BBB. The BBB's 2024 Scam Tracker ranked home improvement as the fifth riskiest category, with a median loss of $1,800 per incident.

Quick Facts

How Do I Find and Verify Foundation Repair Reviews Before Hiring?

You search "foundation repair" and your city name. The first three results are paid ads. Below them, Google's local pack shows three companies with ratings between 4.6 and 4.9 stars. You click the first one — 847 reviews, 4.8 stars. The five-star reviews mention "great team," "professional service," and "highly recommend." They are short, enthusiastic, and largely interchangeable. You notice twelve five-star reviews posted on the same date, all from accounts with only one review.

You scroll to the one-star reviews. One describes a warranty claim denied because the company changed ownership. Another details a repair that failed within two years and a contractor who stopped returning calls. A third describes being told the repair would cost $8,000 but the final invoice was $14,500 after "additional piers were needed" during installation. These negative reviews contain specific details — dates, dollar amounts, names of products — that make them harder to fabricate than the generic five-star entries.

You check the BBB listing for the same company. It shows 7 complaints in the last 3 years, 5 resolved and 2 unanswered. The complaint narratives describe warranty disputes and billing disagreements. The company's BBB rating is A+, which seems contradictory until you realize BBB ratings reflect responsiveness to complaints, not the absence of complaints. The FTC logged approximately 81,925 home improvement scam reports in 2024 — the industry's scale means even legitimate companies accumulate complaints.

You search the company's name through your state's secretary of state database. The business was incorporated 4 years ago, but the owner previously operated under a different company name that was dissolved after BBB complaints. This is the kind of information that never appears in Google reviews.

Why This Happens

Step 1: Review platforms reward volume over accuracy. Google's algorithm favors businesses with more reviews and higher ratings, creating an incentive to solicit five-star reviews from satisfied customers while making complaint resolution less visible. A company with 500 five-star reviews and 20 one-star reviews looks excellent at 4.9 stars — but those 20 negative reviews may describe systematic problems with warranty enforcement, billing surprises, or work quality that affect 4% of customers. On a $25,000 repair, a 4% failure rate represents real financial exposure.

Step 2: Licensing gaps make verification harder in key markets. Texas has no state-level foundation repair license — HB 613 and SB 1399 both failed — meaning you cannot verify a contractor's credentials through a state licensing board. In states with licensing, verification is straightforward: California requires a C-61/D30 license (cslb.ca.gov), Florida uses myfloridalicense.com, Virginia uses dpor.virginia.gov, Arizona uses roc.az.gov, and Tennessee uses verify.tn.gov. In unlicensed states, you must rely on general business registration, insurance verification, and industry association membership as imperfect proxies for competence.

Step 3: Private equity consolidation creates identity confusion. The BBB logged 190 foundation repair complaints in 2022, with 78% ultimately resolved. But companies that change ownership through PE acquisition — KKR acquired Groundworks in February 2023, CenterOak and Cortec closed in January 2025, HCI in November 2025, Percheron in October 2023 — may operate under the same name with different ownership, different management, and different warranty practices. Reviews from before an acquisition may not reflect the current company's performance, and reviews after an acquisition may reflect growing pains rather than the company's long-term track record.

What To Do Next

Step 1: Read negative reviews for patterns, not individual complaints (free). Every company has unhappy customers. The signal is in patterns: multiple complaints about the same issue (warranty denial, billing surprises, communication failures) indicate systemic problems. A single complaint about a rude technician is noise. Three complaints about denied warranty claims over 18 months is a pattern. Focus on reviews that include specific details — dates, dollar amounts, product names — as these are harder to fabricate.

Step 2: Verify business identity and insurance ($0). Search your state's secretary of state website for the company's incorporation date, registered agent, and any previous business names. Call the contractor's insurance carrier directly — request the policy number and confirm it is current. Ask for both general liability (minimum $1 million) and workers' compensation coverage. In licensed states, verify the specific license number on the state board website. A contractor who hesitates to provide insurance documentation is a contractor to avoid.

Step 3: Request three references and actually call them ($0). Ask for references from jobs completed 2–3 years ago, not last month. Recent references confirm the contractor can do the work; older references confirm the warranty and long-term quality. Ask each reference: "Did the repair hold? Did you have any warranty issues? Would you hire them again?" A contractor who cannot provide 2-year-old references either has not been in business that long or does not have satisfied long-term customers.

When You Don't Need Repair

If your only reason for seeking a contractor is anxiety triggered by reading online horror stories, step back and assess your actual symptoms. Hairline cracks under 1/8 inch that have been stable for 12 months, doors that operate normally, and floors level within 1/4 inch over 10 feet do not require structural repair regardless of what the internet suggests. Seasonal sticking doors caused by humidity changes and minor drywall cracks from lumber shrinkage are normal house behavior, not foundation failure. If you have no measurable symptoms of settlement, save your money and your stress. Document what you see with dated photos, maintain proper drainage with a minimum 6-inch grade drop over 10 feet (IRC R401.3), and reassess in a year.

Related Issues to Check

Warranty disputes that follow ownership changes. The BBB's number one complaint category for foundation repair is warranty disputes. When a company is acquired — as has happened with 6+ PE consolidation platforms between 2023 and 2025 — warranty obligations transfer to the new owner, but enforcement can become complicated if the new entity restructures or disputes pre-acquisition commitments.

Contractor licensing and insurance lapses. A contractor with a valid license today may have a lapsed license next year. Insurance policies renew annually, and a contractor who was insured when you signed may not be insured when problems arise. Verify insurance status within 30 days of signing a contract — not at the quoting stage months earlier.

Subcontractor quality on large company jobs. National companies like Groundworks (~80 offices, $1B+ revenue) and Basement Systems (350+ dealers) often use local subcontractors or franchisees for installation. Reviews of the national brand may not reflect your local installer's quality. Ask specifically who will perform the work, verify their insurance separately, and confirm whether the warranty is issued by the national company or the local subcontractor.

Frequently Asked Questions

Can I trust online reviews? Partially — online reviews provide useful signal when you read them critically. Focus on negative reviews with specific, verifiable details rather than positive reviews with generic praise. Look for patterns across multiple review platforms (Google, BBB, Yelp, Angi) rather than relying on a single source. Be suspicious of clusters of five-star reviews posted within short timeframes from single-review accounts.

What is the BBB complaint process? The BBB accepts complaints, forwards them to the business, and tracks whether the business responds. In 2022, 78% of the 190 foundation repair complaints were resolved through this process. Filing a BBB complaint does not guarantee resolution, but it creates a public record and provides leverage — businesses that ignore BBB complaints see their rating drop, which affects their visibility to future customers.

How do I look up a contractor's license? In licensed states, go directly to the state licensing board website: California at cslb.ca.gov, Florida at myfloridalicense.com, Virginia at dpor.virginia.gov, Arizona at roc.az.gov, Tennessee at verify.tn.gov. Search by company name and license number. In states without foundation-specific licensing (like Texas), check general contractor registration through your city or county permitting office and verify insurance independently.

Should review count affect my choice? Review count alone is not a quality indicator — it reflects how actively a company solicits reviews. A company with 50 reviews and a 4.5 rating from detailed, verified customers may be a better choice than one with 1,000 reviews and a 4.8 rating dominated by one-sentence endorsements. Look at the ratio of detailed reviews to generic ones, and weight reviews that describe specific experiences over those that could apply to any service business.

Negative reviews about communication matter less than those about work quality or warranty disputes. A contractor's response to negative reviews reveals character more than five-star ratings. Start with verified contractors who stand behind their work.
