What to look for
- Years in business and a local track record
- Liability insurance
- A written repair plan with pier type, number and placement
- A warranty that's clear about what's covered and whether it transfers
- Willingness to work from an engineer's report
Questions to ask before you hire
- What type of piers do you use, and how many?
- How deep will they go?
- Who pulls the permit, if one is needed?
- Is the warranty transferable, and are there fees?
- Do you handle drainage problems that caused the damage?
Getting and comparing quotes
Give each company the same engineer's report or ask them to bid the same plan. Compare the number and type of piers, not just the total, and ask how they'll handle plumbing under the slab.
Red flags
- Pressures you to sign the same day
- Diagnoses major damage without measuring
- Won't put pier count and placement in writing
- Offers a warranty that's vague or not transferable
