A foundation repair inspection costs $400 to $1,500 and produces the measurements that everything else depends on. It is not a contractor's free estimate, and it is not a home inspection. It is a licensed engineer's written opinion on what is moving, why, and what repair will stop it.

## What the Inspection Measures

The engineer measures crack widths at their widest point, records floor elevations room by room, checks wall plumb at three heights, and reviews the drainage and site grading. On a crawl space house, the piers and beams are examined directly. On a slab, the perimeter and the visible interior cracks are mapped.

The report should include photographs with a scale in frame. A crack described as "significant" is an opinion; a crack photographed beside a gauge reading 3/16 inch is evidence. Ask for the images before the visit ends so there are no surprises.

## The Three Readings That Matter

| Reading | Method | Threshold |
|---|---|---|
| Crack width | Graduated gauge | 1/8 inch for monitoring |
| Floor elevation | Zip level or laser | 1 inch drop across a room |
| Wall plumb | 4-foot level or plumb line | 1 inch out of plumb |

Crack width tells you whether the movement is active. Elevation tells you how far the structure has dropped and whether lifting is practical. Plumb tells you whether the wall is bowing rather than settling, which changes the method entirely.

## What the Report Should Contain

A usable report runs 5 to 15 pages. It names the foundation type, describes the defects, states a cause, recommends a repair method with a unit count, and sets a lift tolerance. It should also state what the engineer does not recommend and why.

The unit count is the part contractors bid against. "Install piers to stabilize" is not a scope. "Install eight push piers at 7-foot spacing, design depth 22 feet, lift to within 1 inch of level" is a scope.

## Inspection Cost Versus Repair Cost

An inspection at $400 to $1,500 is 2% to 7% of a $20,000 repair. Skipping it to save the fee means the contractor defines the scope, and the contractor's scope is the one that gets sold.

Consider the arithmetic. Two bids without an engineer's report:

Bid A: 6 piers at $2,100 = $12,600
Bid B: 9 piers at $1,800 = $16,200

Without a design, there is no way to know which count is right. With a report specifying eight piers, both bids become comparable, and the $3,600 difference is resolved by the count rather than by sales pressure.

## Engineer Versus Contractor Estimate

| Feature | Engineer inspection | Contractor estimate |
|---|---|---|
| Cost | $400 - $1,500 | Free |
| Measurement | Full survey | Often visual |
| Report | Written, stamped | Proposal |
| Financial interest | None in the method | Sells the method |
| Usable for bids | Yes | Only with that firm |

A free estimate is not worthless. It is a sales conversation that can tell you what a contractor would propose. It is not a diagnosis, and it should not be the only input before a $20,000 decision.

## How to Prepare

1. Write down the symptoms and when they started.
2. Photograph every crack with a ruler or coin for scale.
3. Note doors and windows that stick, and where.
4. Clear access to the basement, crawl space, and garage.
5. Have the age of the house and any prior repairs available.
6. Ask whether the engineer will inspect the crawl space personally.

## What to Do With the Report

Send the same report to at least three contractors and require bids against it. Ask each to state the pier count, the design depth, and the exclusions. Compare the all-in totals, then choose on scope clarity rather than on the lowest number.

Keep the report. It is the document that supports a warranty claim, an insurance claim, and a resale disclosure. A buyer's inspector will find the crack regardless; the report is what shows the repair was engineered and completed to a design.

## Common Findings and What They Mean

Most reports land on one of four findings. A settled corner with a stair-step crack means the footing has dropped and the repair is underpinning. A bowing wall with a horizontal crack means lateral pressure and the repair is restraint. A stable vertical crack with efflorescence means water is moving through the wall and the repair is drainage plus injection. Widespread slab cracking with no elevation loss is often shrinkage and needs nothing structural at all.

The fourth finding is the one homeowners rarely expect. Many foundations that look alarming in a photograph are performing normally, and the most valuable thing an engineer can do is tell you that monitoring is the correct response. A report that recommends monitoring with a measurement date is not a wasted fee; it is a $500 answer that prevents a $15,000 repair no one needed.

Ask the engineer to rank the findings by consequence rather than by cost. A report that lists everything as urgent gives a homeowner no way to sequence the work, and sequencing is often what makes the project affordable. The ranking also protects you from a contractor who proposes the most expensive item on the list first.
