Foundation repair is a major purchase, and the contractor you choose matters as much as the repair method. A good contractor diagnoses accurately, recommends only what you need, and stands behind the work. A bad one sells you the most expensive fix whether you need it or not — or does shoddy work that fails in a few years. This guide gives you the questions to ask, the red flags to watch for, and a clear picture of what a legitimate inspection looks like.
Questions to Ask Every Contractor
About the diagnosis
Ask: What exactly is wrong with my foundation, and what is causing it? Can you show me? A trustworthy contractor points to the evidence — the crack pattern, the measurements, the water path — and explains it in plain language. Be wary of anyone who cannot clearly explain the cause, or who diagnoses a major problem in five minutes without measuring anything.
About the repair method
Ask: Why this method and not the alternatives? What are the trade-offs? There is often more than one valid way to fix a foundation problem. A good contractor explains the options — for example, wall anchors versus steel beams for a bowing wall (bowing wall repair) — including cost and effectiveness differences. One who presents only a single take-it-or-leave-it option may be selling, not advising.
About the quote
Ask for everything in writing: an itemized price (not one lump sum), the specific materials and method, the project timeline, the payment schedule, and the warranty terms. Ask what happens if they find additional damage once work starts — how are change orders priced and approved? Surprises mid-project are where budgets blow up.
About the warranty
Ask: What exactly does the warranty cover, for how long, and is it transferable if I sell the home? Get the warranty in writing before work starts, not after. A "lifetime warranty" means little if the company is new or the fine print excludes the actual failure modes. Transferable warranties matter for resale — see foundation repair and home value.
About the company
Ask how long they have served the local area, whether they carry general liability insurance, who will actually do the work (employees or subcontractors), and whether they handle permits. Ask for local references — and actually call them.
Red Flags
Walk away or get a second opinion when you see these:
High-pressure sales tactics
"This price is only good today," limited-time discounts that reset every visit, or scare tactics about your house collapsing. Foundation problems are serious but rarely emergencies requiring a same-day signature. Legitimate urgency (active flooding, a wall moving fast) is different from manufactured urgency.
Diagnosis without inspection
Quotes given over the phone or from the driveway without going into the basement or crawl space, without measuring, without photos. You cannot diagnose a foundation you have not looked at.
The most expensive fix as the only option
If three contractors recommend targeted piering and one insists on full replacement without clear evidence, trust the pattern. See repair vs. replacement.
Demanding full payment up front
Reasonable deposits are normal; full payment before work starts is not. Tie payments to milestones and hold final payment until the walkthrough is complete.
No written warranty or vague paperwork
Verbal promises about warranties, timelines, or scope mean nothing. If it is not in writing, it does not exist.
Far cheaper than everyone else
A bid dramatically lower than the others usually means cut corners — fewer piers than needed, thinner materials, no permits, or a company that will not be around to honor the warranty.
What a Good Inspection Looks Like
A real foundation inspection takes 30 to 90 minutes. The inspector walks the exterior and interior, measures cracks and floor slope, checks the basement or crawl space, looks at grading and drainage, takes photos, and explains findings on the spot in plain language. You should receive a written report with photos and an itemized proposal — not just a price scribbled on a business card.
Crucially, a good inspector sometimes tells you that you do not need repair — that a crack is stable shrinkage, or that grading fixes will solve the water issue. A company that finds a five-figure problem in every home it visits is not inspecting; it is selling. See what our inspection includes.
Get Multiple Quotes
For any project over a few thousand dollars, get at least two or three written quotes. Compare the diagnosis (do they agree on the problem?), the method (do they agree on the fix?), the scope, the warranty, and the price. Similar diagnoses with different methods deserve a conversation about trade-offs. Wildly different diagnoses mean you need a tiebreaker — possibly from a structural engineer, who has no repair work to sell you.
When you are ready, start with a free inspection and see how the process feels. The quality of the inspection tells you most of what you need to know about the company. For background on costs and timelines while you compare, see foundation repair costs and project timelines.
Reading the Contract Before You Sign
The proposal becomes the contract, so read it like one. Here is what should be in it — and what should make you pause.
Must-haves in writing
The specific problem being fixed, described plainly. The exact repair method and materials (pier type and count, beam size and spacing, drain pipe specifications — not just "foundation repair"). The total price, itemized. Start and estimated completion dates. The payment schedule tied to milestones. The warranty: what it covers, how long, whether it transfers, and what voids it. Who handles permits. How change orders are priced and approved. Cleanup and restoration responsibilities — who reseeds the lawn, who repours what.
Pause and ask about
Vague scope descriptions ("repair foundation as needed"), full payment demanded before work begins, warranty language with broad exclusions, no mention of permits for structural work, and verbal promises that do not appear in the document. Anything important that was said out loud but is missing from the paper needs to be added before you sign.
Keep your paperwork
File the signed contract, the warranty, permit records, and before-and-after photos together. If you sell the home, this folder is what turns a buyer's worry into confidence — see foundation repair and home value. If you ever need warranty service, it is your proof.
