How to Choose a Foundation Repair Company

Step 1: Verify Licensing and Insurance

Foundation repair licensing requirements vary by state. Some states require a general contractor's license, others require a specialty structural or foundation license, and a few have minimal requirements. Regardless of your state's minimums, the company you hire should carry general liability insurance of at least $1 million per occurrence and workers' compensation insurance covering all employees on the job site.

Ask for the license number and verify it with your state's licensing board. Ask for a certificate of insurance and verify it with the insurance company directly. A legitimate contractor provides these documents without hesitation. A contractor who resists or delays providing proof of licensing and insurance is not worth considering, regardless of how competitive their bid is.

Check whether the company has any complaints filed with your state's consumer protection office or attorney general. The Better Business Bureau and your state contractor licensing board both maintain complaint records that are publicly searchable.

Step 2: Check Reviews and References

Read reviews on Google, Yelp, the BBB, and any local platforms popular in your area. Pay attention to the substance of both positive and negative reviews rather than just the overall rating. Negative reviews that describe unresponsive warranty service, unexpected costs, or poor communication reveal more about a company's operations than star ratings alone.

Ask the company for 3 to 5 references from jobs completed in the past 12 months. Contact these references and ask specific questions: Was the work completed on schedule? Were there any cost surprises? How responsive was the company after the work was done? Would you hire them again? Companies that cannot or will not provide recent references should be viewed skeptically.

Ask how long the company has been in business and whether they have operated under any previous names. Longevity matters in foundation repair because the warranty is only as reliable as the company's continued existence. A company with 20 years in business under the same name provides more warranty certainty than a 2-year-old company, regardless of how polished their marketing is.

Step 3: Get Three to Five Written Estimates

Have at least three companies, preferably five, inspect your foundation and provide written proposals. Each proposal should include a detailed scope of work specifying the repair method, the number and type of piers, the locations of all work, the warranty terms, the total price, and the payment schedule. Vague proposals that do not itemize the work or specify the pier type and count are inadequate for comparison purposes.

During the inspection, observe how thorough the inspector is. A proper evaluation includes measuring floor elevation at multiple points (using a manometer or laser level), examining the exterior of the foundation, checking interior symptoms like wall cracks and door alignment, and in some cases crawling beneath the home. An inspector who spends 15 minutes and provides a verbal quote is not performing a competent evaluation.

Be cautious of high-pressure sales tactics. Some companies offer "today only" discounts or claim the price will increase if you do not sign immediately. Legitimate foundation repair companies provide written proposals with a reasonable validity period (typically 30 to 60 days) and do not pressure you to sign on the spot. The urgency is in addressing your foundation problem, not in choosing a contractor before you have compared options.

Step 4: Compare Warranty Terms

Request the full written warranty document from each company, not just a verbal summary. Compare the duration (lifetime versus 25 years), the transferability (automatic versus fee-based versus non-transferable), the coverage (materials and labor versus materials only), and the exclusions. A transferable lifetime warranty on materials and labor is the industry standard for steel pier installations. Anything less than this should be questioned.

Ask whether the warranty is backed by a third party. Some companies carry warranty insurance through an independent provider, which means the warranty obligations are covered even if the repair company goes out of business. This third-party backing is particularly valuable from smaller or newer companies whose long-term survival is less certain.

Step 5: Hire an Independent Structural Engineer

Paying $300 to $800 for an independent structural engineer's evaluation before committing to a repair company is one of the smartest investments in the entire process. The engineer works for you, not for any repair company, and provides an unbiased assessment of what your foundation actually needs. This report serves as a baseline for evaluating each contractor's proposal, which makes it much easier to identify companies that are recommending more work than necessary or using methods that do not match the engineering requirements.

Bring the engineering report to each contractor visit and ask how their proposal aligns with the engineer's recommendations. A reputable contractor will respect the engineer's findings and adjust their proposal accordingly. A contractor who dismisses the engineering report or insists on a significantly different scope without a compelling technical explanation is prioritizing their sales goals over your home's needs.

Step 6: Review the Contract Thoroughly Before Signing

Read every section of the contract, including the fine print. Confirm that the scope of work matches the written proposal, that the warranty terms are the same as what was presented, that the payment schedule is reasonable (never pay more than 10 to 20 percent upfront), and that the contract includes a clear cancellation policy. State law in most jurisdictions provides a 3-day right of rescission for home improvement contracts, but confirm this right is stated in the contract.

Verify that the contract includes start and completion dates, provisions for weather delays, and a description of what happens if unexpected conditions are encountered during the work. A well-written contract protects both you and the contractor by setting clear expectations before work begins.
