Structural repair services

Most of what gets sold as "foundation repair" is one of five things. Crack sealing or epoxy injection closes a crack so water stops coming in; it does not stop movement. Slab jacking or mudjacking pumps material under a sunken slab to raise it back. Piering or underpinning drives steel or concrete piers down to stable soil or bedrock and transfers the house's weight onto them. Bowing-wall repair uses carbon fiber straps, steel I-beams or wall anchors to hold a wall that soil pressure is pushing inward. House leveling lifts and re-shims the whole structure.

Fixr's 2026 figures put crack sealing at $200-$1,000, mudjacking at $500-$1,900, carbon fiber strips at $4,000-$12,000, tiebacks at $5,000-$15,000, underpinning at $10,000-$40,000 and house lifting at $20,000-$30,000. That spread is the whole problem: the same symptom can lead to a $600 fix or a $30,000 one, and the person diagnosing it is usually the person selling it.

This site will not tell you what your cracks mean. Nobody can diagnose a structure from a photo or a description. A specific crack pattern, door that sticks, or sloped floor can have several very different causes, and only a licensed structural engineer who walks the property, takes elevations and looks at soil and drainage can say which one you have.

The sensible order is: document what you see, get an independent structural engineer's opinion in writing, then take that report to contractors for bids. Doing it the other way round means every bid answers a different question.

How to choose

Get the diagnosis and the repair from different people

A repair company's free inspection is a sales call. An independent structural engineer costs $350-$800 on average per Today's Homeowner's 2026 data, and they have no product to sell you.

Match the service to the cause, not the symptom

Sealing a crack caused by ongoing settlement just hides it. If the ground is still moving, the crack comes back.

Ask what the repair is designed to do

Stabilize (stop further movement) and lift (return to original position) are different jobs at very different prices. Many piering jobs only promise stabilization.

Drainage work is often part of the fix

Water in the soil drives a lot of foundation movement. This Old House notes horizontal cracks come from soil pressure on the wall. If nobody mentions grading, gutters or drains, ask why.

Be skeptical of same-day pricing

Structural work is not an impulse purchase. Any discount that expires when the salesperson leaves is a sales tactic, not a price.
