The quote does not explain the diagnosis
A proposal should explain what is moving, leaking, bowing, sinking, or cracking and what evidence supports that conclusion. A price without a diagnosis is hard to compare and easier to oversell.

- How will drainage, grading, or plumbing leaks be ruled out before repair?
- Can you show comparable local projects with similar foundation conditions?

Get a Quote Review Checklist
Send the basic project details and quote text. The form is built to work before you add a mail provider, and can email leads once `RESEND_API_KEY` and `LEAD_TO_EMAIL` are set.
Good for high-price pier, waterproofing, slab, and crawl space quotes.
Avoids collecting payment or sensitive documents on the first pass.
The repair quantities are vague
Look for pier count, pier locations, wall length, drain length, crack length, injection points, beam length, or crawl space areas. If quantities are missing, two quotes may not be pricing the same work.
The contractor pressures you to sign today
Same-day discounts, financing pressure, and fear-based language do not prove a quote is wrong, but they are reasons to slow down and get the scope in writing before committing.
Exclusions are missing
A strong quote should say what is not included: plumbing, drainage, landscaping, permits, engineering, drywall, concrete patching, flooring, cleanup, or future movement outside the repair area.
Warranty terms are only verbal
Ask for the written warranty before signing. Confirm covered areas, exclusions, transfer rules, maintenance duties, claim process, and whether drainage or plumbing issues can void coverage.

FAQ
What is the biggest red flag in a foundation repair quote?
The biggest red flag is a high-cost quote that does not explain the diagnosis, repair quantities, repair locations, exclusions, warranty terms, and payment schedule in writing.
Is a very low foundation repair quote a red flag?
It can be. A low quote may leave out drainage, engineering, permits, warranty coverage, cleanup, or enough piers to address the actual movement. Compare scope before comparing price.
Should a foundation repair quote include pier locations?
Yes, if piers are part of the proposed repair. The quote should show how many piers are included and where they will be installed.
Is a same-day foundation repair discount suspicious?
A discount is not automatically suspicious, but pressure to sign before you can review the scope or get another opinion is a warning sign.
What should I ask before accepting a foundation repair quote?
Ask what caused the problem, what evidence supports the diagnosis, what quantities are included, what is excluded, how changes are priced, and what the warranty actually covers.
