How do I hire a foundation repair contractor?

The answer

Hire a foundation contractor who explains the failure pattern, documents the symptoms, separates water control from structural repair, and gives a written scope before asking for a signature. For major piering, bowed walls, or conflicting opinions, consider an independent engineer.

The best contractor does not just sell a system. They show whether the issue is settlement, soil pressure, drainage, crawlspace moisture, framing, or a stable crack.

Questions to ask on the estimate

  1. What is causing the problem: water, soil pressure, settlement, framing, or a stable crack?
  2. What happens if I only fix drainage first?
  3. Does this quote stabilize, lift, waterproof, or only seal?
  4. Do you recommend an engineer? If not, why not?
  5. What photos, measurements, permits, warranty documents, and post-work records will I receive?

Red flags

  • Same-day pressure for a high-dollar structural repair
  • They recommend piers, anchors, or encapsulation without explaining the cause
  • The quote ignores gutters, grading, sump discharge, and drainage
  • Warranty language sounds broad but has unclear exclusions
  • They dismiss engineer review when movement is significant or recommendations conflict

One quote vs. second opinion

Get a second opinion when the recommendation is expensive, structural, or very different from what another contractor said. For major movement, piering, or bowed walls, an independent engineer can be cheaper than buying the wrong system. For a small leaking crack, a good contractor with clear documentation may be enough.

Related questions

Should I use a foundation company or structural engineer first?

For small leaks or straightforward cracks, a foundation company may be fine. For structural movement, expensive piering, bowed walls, or conflicting quotes, an independent engineer is worth considering.

What license should a foundation contractor have?

Requirements vary by state and project type. Ask for license, insurance, local permits if required, and whether engineering is needed for structural work.

How many foundation repair quotes should I get?

For major work, get at least two contractor opinions or one contractor plus an engineer. Compare diagnosis and scope, not just price.

What should be in a foundation repair contract?

Diagnosis, scope, quantities, system details, exclusions, access/restoration, payment schedule, warranty, permit/engineering responsibility, and documentation you receive after completion.
