How to hire a foundation repair contractor

Start with written quotes

Get at least two or three written quotes on the same scope. A phone number or a door-to-door discount is not a substitute for a site visit and a written proposal.

Ask how they diagnosed the movement or cracks, and whether they are also looking at drainage.

Ask who, if anyone, provides engineering, and how the completed work will be documented.

Get proof of insurance and any required license, and confirm those with the issuing agency where your state or city requires them.

Questions to ask

• What is causing the movement, and how did you determine that?
• Which repair method do you recommend, and why that one?
• Will a structural engineer review the plan?
• Is the warranty transferable, and what does it cover?
• Who pulls permits?

Licensing, insurance and references

Ask for license and insurance details and confirm them with the issuing agency where your state or city requires them. We confirm a listed company's business name, contact details and service area before publishing; we do not inspect work, endorse contractors or publish reviews, so check references yourself.
