Questions to ask contractors

Planning and homeowner guidance

What information should I gather before a foundation inspection?

Photograph the areas that concern you and record when you first noticed them, including cracks, sticking doors, uneven floors, or water collecting near the house. Note whether anything appears to be changing and whether you’ve noticed a connection with rainfall or dry periods. Gather previous inspection reports, repair records, and warranty documents if available. Share these observations with the person inspecting your home, while leaving the diagnosis open. A useful inspection should investigate the concern rather than begin with a predetermined repair.

How can I understand what is causing my foundation concerns?

Ask the evaluator to explain what they observed, what those findings suggest, and what remains uncertain. Which measurements or other evidence support their conclusions? Were drainage conditions considered, and are there areas they could not inspect? Ask whether further evaluation is needed before choosing a repair. If recommendations differ substantially or involve extensive work, consider an independent structural assessment to help you understand the findings. You should be able to follow the reasoning from the observed problem to the proposed response.

What should a foundation repair proposal explain?

A proposal should identify the problem being addressed, the proposed repair locations, and the intended result. Ask why that approach was selected, what alternatives were considered, and what the work is unlikely to resolve. Clarify responsibilities for any engineering, approvals, inspections, and utility coordination the project requires. The scope should also explain access, excavation, cleanup, and restoration of disturbed areas. Read warranty terms carefully, including coverage, exclusions, transfer conditions, and who handles a future claim.

What happens after foundation repairs are completed?

Before work begins, ask what completion records you will receive and how the contractor will evaluate the result. Discuss whether follow-up visits or measurements are included and whom to contact if concerns persist or new changes appear. Clarify how related work, such as repairing interior finishes or restoring landscaping, will be coordinated. Keep the proposal, repair documentation, photographs, and warranty together. Ask for any maintenance or monitoring recommendations in writing so you understand your responsibilities after the crew leaves.
