Structural repair FAQ

The most common questions are what it costs, whether a crack is serious, and who to trust. Foundation repair averages $5,179 with most projects between $2,224 and $8,134 (This Old House, 2026). An independent structural engineer costs $350-$800 on average (Today's Homeowner, 2026) and is the right first spend, because no one can diagnose a structure remotely.

The single most useful thing on this page: separate the person who diagnoses from the person who repairs. Nearly every homeowner horror story in this trade starts with a free inspection from a company that sells the fix.

The second most useful thing: we cannot tell you what your cracks mean, and neither can any website. Crack shape is a prompt to investigate, not a diagnosis. Soil, drainage, age, construction and load all matter, and they can only be assessed on site.

How to choose

Pay for the diagnosis
$350-$800 for an independent engineer (Today's Homeowner, 2026) against an average $5,179 repair is good math.
Three bids, one scope
Give every contractor the engineer's report so the bids are comparable.
Written warranty, before signing
Coverage, exclusions, transferability. Verbal terms are worth nothing.
No same-day signatures
Urgency created by a salesperson is not the same as structural urgency.

This Old House puts the 2026 national average at $5,179, with most projects between $2,224 and $8,134. By method, Fixr's 2026 ranges run from $200-$1,000 for crack sealing up to $10,000-$40,000 for underpinning and $20,000-$30,000 for house lifting.
If the symptoms suggest movement — widening cracks, sloping floors, sticking doors, a bowing wall — yes. Today's Homeowner puts a residential structural engineer at $350-$800 on average, $400-$1,500 for a foundation inspection, or $70-$250 per hour in 2026.
Warning signs: diagnosis without an elevation survey, no written scope, prices that drop when you hesitate, refusal to provide the warranty document before signing, and no mention of drainage or the underlying cause. Get three bids against an independent engineer's scope.
No. This Old House describes hairline cracks as usually cosmetic curing shrinkage. What matters is change: a crack that appeared suddenly or keeps growing is the one to have looked at.
Yes, though it will affect price and buyer financing in some cases. Documented, engineer-specified, permitted and warrantied repairs are far easier to sell than an undisclosed or undocumented problem — and disclosure obligations are set by your state.
