Questions to ask

  • What failure mode are you diagnosing, and what evidence supports it?
  • Does this quote include permits, engineering, cleanup, and warranty terms?
  • Which line items are required now, and which are optional upgrades?
  • How will drainage, grading, or plumbing leaks be ruled out before repair?
  • Can you show comparable local projects with similar foundation conditions?

Good for high-price pier, waterproofing, slab, and crawl space quotes.
Avoids collecting payment or sensitive documents on the first pass.

Why access matters

Low crawl spaces can slow work, limit equipment, and increase labor. Moisture, rot, mold, and pest damage can also expand the repair scope.

What belongs in the quote

Look for pier count, beam length, joist repair details, vapor barrier scope, drainage work, and whether temporary shims are being replaced with permanent supports.

FAQ

Should I use this page as a final repair price?

No. Use it as a planning range only. A final price depends on inspection findings, soil conditions, access, permits, drainage, materials, and engineering requirements.

How many quotes should I compare?

Most homeowners should compare at least two or three written scopes, especially when the repair involves piers, waterproofing, wall stabilization, or structural movement.
