Structural repair guides
A good structural repair process has four stages: document what you see over time, pay an independent structural engineer for a diagnosis ($350-$800 on average, Today's Homeowner 2026), bid the engineer's scope to three contractors, and keep the full paperwork. The average repair is $5,179 (This Old House, 2026), which is enough money to justify doing it in that order.
Documenting. Photos with scale, dated pencil marks at crack ends, monthly measurements, and notes on when doors started sticking. Also note the weather: many symptoms follow very wet or very dry seasons, and that pattern helps identify soil-driven movement.
Hiring the engineer. Look for a licensed professional engineer in your state who does residential forensic work and does not sell repairs. Ask what the fee includes: site visit, elevation survey, written report, and whether follow-up questions or reviewing contractor bids is included.
Reading the quote. Find the method, the quantity, the depth, the outcome promised, what's restored, what's excluded, warranty terms and transferability. If any of those are missing, the quote is incomplete regardless of the number at the bottom.
What good looks like at the end. Permit closed where required, engineer sign-off on the completed work, as-built elevations, photos before backfill, and a warranty in your name. That file is worth real money when you sell.
Choosing structural repair an approach
The judgement calls that decide the bill, before anyone quotes you.
- Start a folder on day one Photos, dates, quotes, reports. Structural stories play out over years and memory is not evidence.
- Do not sign at the kitchen table Take every proposal away and compare it against the others in daylight.
- Ask about the failure mode "What happens if this doesn't work?" is the most useful question you can ask a contractor. The answer tells you how confident they really are.
- Verify licensing and insurance Check the engineer's state license and the contractor's license and liability coverage yourself, with the issuing body - not from a certificate they hand you.
