More foundation repair questions
How much does foundation repair cost?
A typical foundation repair costs about $2,176–$7,833. Piers usually cost $1,000–$3,000 each, so the number of piers drives the total.
How much does a structural engineer foundation inspection cost?
Engineer evaluations commonly cost several hundred dollars. It is worth paying for an independent opinion before hiring a repair company.
Are hairline cracks in a slab foundation normal?
Yes. Thin shrinkage cracks under about 1/8 inch are common in concrete. Wider cracks, cracks that grow or cracks with height differences need an evaluation.
How many piers does a house need?
It depends on how much of the house has moved. A corner might need only a few piers, while a whole side can need 10 or more. An engineer should set the plan.
Does homeowners insurance cover foundation repair?
Usually not for settling, soil movement or wear. Coverage typically applies only when a covered event, such as a sudden plumbing leak, causes the damage.
Is foundation repair permanent?
Piers driven to stable soil or bedrock are designed to last the life of the house, but steady soil moisture and good drainage keep the rest of the slab from moving.
Should I buy a house that had foundation repair?
It can be fine if the work was engineer-specified, permitted and comes with a transferable lifetime warranty. Ask for the paperwork.
How do I protect my foundation during a drought?
Keep soil moisture steady with a soaker hose a foot or so from the slab, maintain gutters and grading, and keep thirsty trees away from the foundation.
Timeline, permits and DIY
How long it takes
Pier installation usually takes 1–3 days. Wall stabilization and waterproofing take 1–5 days.
Permits
Structural foundation repair often needs a permit and an engineer's letter, especially for resale.
DIY or hire a pro?
Grading, gutters and steady soil moisture are DIY prevention. Structural repair needs a licensed contractor and, ideally, an independent engineer.
Questions to ask contractors
Ask every bidder the same questions so you can compare quotes apples to apples.
- Has an independent structural engineer evaluated the house?
- How many piers, how deep, and what pier type?
- Is the warranty lifetime and transferable to a buyer?
- Who handles the plumbing test and permit?
Maintenance that prevents costly repairs
- Keep soil moisture steady around the slab
- Discharge downspouts at least 5 feet from the house
- Grade soil to slope away from the foundation
