Questions to ask a foundation repair company (with good answers)
Walking into a foundation inspection without questions is how vague quotes win. Nationally, most homeowners pay $2,225–$8,133 for repair (Angi, 2026). Use these 18 questions, and the "good answer" notes, to interview any San Antonio company, including a network partner we match you with.
Picture this
Here's a typical scenario (not a real customer). Two companies quote similar totals. Only one answers "why did it move," shares elevations, and hands over the warranty before asking for a deposit. The questions below are what made the difference.
18 questions (and what a good answer sounds like)
- What caused the movement on my house?
Good answer sounds like: A specific cause tied to what they saw: drainage, plumbing, drought/rain cycles, roots, fill, or a mix, not just 'clay soil' with no plan. - Can I see the elevation readings?
Good answer sounds like: Numbers or a sketch across rooms, shared with you, not only a verbal summary. - Which repair method do you recommend and why?
Good answer sounds like: A method matched to the cause, with alternatives and limits explained. Compare options on our methods guide. - How many piers, what type, and how deep?
Good answer sounds like: Pier count, type (segmented, steel push, helical, etc.) and depth or refusal criteria in writing. - What is the cost per pier and what is included?
Good answer sounds like: A line-item that you can check against national ranges (Angi often lists piering around $1,000–$3,000 per pier). - What work is excluded from this quote?
Good answer sounds like: Clear list: plumbing tests, landscaping, drywall, flooring, permits, drainage, etc. - Will you check for under-slab plumbing leaks?
Good answer sounds like: Yes, no, or coordinated with a plumber, with a reason that fits your symptoms. - Who pulls the permit and is the fee included?
Good answer sounds like: Named responsibility and whether Angi's typical permit range is already in the price. - What does the warranty cover, for how long, and does it transfer?
Good answer sounds like: Written terms covering scope, exclusions, transfer rules and claim process. See our warranty guide. - What maintenance must I do to keep the warranty valid?
Good answer sounds like: Specific duties (drainage, watering, gutters) in writing. - Can I have the full warranty document before I pay a deposit?
Good answer sounds like: Yes, before money changes hands. - What proof of insurance can you provide?
Good answer sounds like: A current certificate of liability insurance. - What is the payment schedule?
Good answer sounds like: A schedule that does not demand most of the job cost before work meaningfully starts. - How long do you estimate the work will take, and what could change that?
Good answer sounds like: A range with dependencies (permits, weather, discoveries), not a pressure deadline. - Will a structural engineer design or review this plan?
Good answer sounds like: A clear yes/no and whether an engineer letter is included or available as an add-on. - How do you handle drainage and moisture around the home?
Good answer sounds like: Concrete recommendations (grading, gutters, soaker strategy) when clay moisture is part of the cause. - What happens if the house settles again in a covered area?
Good answer sounds like: A claim process that includes remeasuring and a stated remedy. - Are you okay with me getting a second opinion?
Good answer sounds like: Willingness without pressure. Pushback is a warning sign.
How to use the list
- Ask the same questions of every company so quotes stay comparable.
- Write answers down; memory fades after three sales visits.
- Pair this list with how to compare SA companies and red flags.
- For warranty-specific deep dives, open foundation repair warranty.
Local context worth mentioning
San Antonio's expansive clay (Texas Master Naturalist) makes moisture history and drainage questions non-optional. High moisture can heave; low moisture can settle (TDLR). If a company shrugs those off, keep asking, or keep looking.

How many questions should I ask at a foundation inspection?
Enough to understand cause, scope, method, warranty and payment. The list below covers about 18 essentials. Bring it on your phone and take notes.
What is the most important question?
Why did my foundation move, and how do your measurements support that? A method without a cause is hard to trust on expansive clay.
Should I ask about insurance and permits?
Yes. Ask for proof of liability insurance and who pulls permits. Angi lists foundation-related permits nationally around $75–$150.
Does LevelSATX Foundation Network answer these for the contractor?
No. We match you with one vetted, independent network partner for a free inspection. You ask the questions; they answer. We don't perform repairs.
What if answers are vague?
Treat vagueness as a red flag. See our red flags guide and compare another company before you sign.
