Piers, crack repair, slab lifting and wall anchors, priced the way contractors quote them: per pier, per crack, per square foot. Check any bid line by line before you sign.
Each method priced at your inputs and severity, with the engineer, permit and testing lines included.
National US ranges for planning. The right method depends on your soil and the cause, not on price.
Use these to describe the problem to an engineer. Only an inspection can confirm the cause.
If a crack grows, mark its ends with a pencil and date; growth over weeks is useful evidence for an engineer.
Pier count = wall length ÷ spacing, rounded up, plus one. Your engineer may specify a different spacing.
*At 6 ft spacing × $1,800 per pier, before engineer, permit and testing.
Most US homeowners pay a few thousand dollars for crack repair and roughly $8,000–$25,000 for piering, depending on how many piers are needed. A typical job uses 8–12 piers.
Contractors usually space piers 6–8 ft apart along the settling wall, plus one at each end. 30 ft of affected wall at 6 ft spacing needs about 6 piers.
Steel push piers use the house weight to drive down to firm strata and suit heavier homes. Helical piers are screwed in and suit lighter loads or where the house can't provide enough weight.
It's strongly recommended. An independent engineer (not one hired by the repair company) diagnoses the cause and specifies the fix, usually for $500–$3,000.
Usually not for settling, soil movement or poor drainage. It may cover damage from a sudden covered event, like a burst pipe. Check your policy.
No. Hairline vertical cracks under 1/8 in are often shrinkage. Horizontal cracks, stair-step cracks in block, or cracks wider than 1/4 in should be looked at.
Lifting a slab can stress or crack under-slab drain lines. Testing before and after documents what was already broken versus what the repair caused.
Whether it's transferable to a new owner, what it covers (re-adjustment, not just the pier), any fees to transfer, and that it's backed by a company that will be around.
