The problem with comparing totals
Three proposals arrive with three different numbers, and the instinct is to sort them by price. That only works if all three describe the same project, and in foundation repair they very often do not.
One may propose underpinning eight support points. Another may propose drainage correction and monitoring. A third may propose stabilization of a wall the first two barely mentioned. These are not three prices for one job; they are three opinions about what is wrong.
Start with the diagnosis, not the price
Read the section of each proposal that describes the problem. It should state what was observed, where, and what measurements support it. If a proposal skips straight to the solution, you are being sold a product rather than offered a repair.
Where two proposals disagree on the cause, that disagreement is the thing to resolve first. Ask each company what measurements support their conclusion. A company that recorded relative floor elevations, crack widths, and deflection has an argument. A company that walked around for ten minutes has an impression.
The comparison checklist
Problem described. What was observed and measured, not just what is being sold.
Proposed work. The method, and why it suits the conditions found.
Quantities. Number of support points, linear feet of drainage, square footage of reinforcement, number of straps or anchors. Two quotes with the same method and different quantities are different projects.
Access assumptions. What the contractor expects to be able to reach, and what happens if they cannot.
Exclusions. The most important paragraph in any proposal. What is explicitly not included?
Permits. Who applies, who pays, and whether the price includes the coordination time.
Engineering. Whether a stamped design or independent report is required, who arranges it, and who pays.
Cleanup and restoration. Spoil removal, landscaping, hardscape, driveway sections, interior finishes. Is any of it included, and to what standard?
Payment stages. Deposit, progress payments, final payment, and what triggers each.
Change orders. How variations are priced and approved. Specifically, what happens if piers need to go deeper than assumed.
Timeline. Duration, sequence, and disruption expectations.
Warranty. Covered work, duration, responsible company, transfer conditions, exclusions, and service process. Our guide on repair warranties explained breaks that down.
Licensing and insurance. Verifiable licence classification and current insurance, which you can check independently.
Why the cheapest is sometimes genuinely cheapest, and sometimes not
A lower number can reflect a genuinely leaner but adequate scope, better access assumptions, or simply lower overhead. Cheap is not automatically bad.
It can also reflect fewer support points than the conditions warrant, no permit allowance, no restoration, no engineering, or an intention to handle the difference through change orders once work has started.
You can tell the two apart by reading the exclusions. That is the whole trick.
Questions worth asking each company
What measurements did you take, and can I see them? Why this method rather than the alternatives? What happens if conditions differ from your assumptions? Who pulls the permit? What is excluded? What does your warranty cover, for how long, and does it transfer? Can I speak with customers whose work is comparable to mine?
The answers tell you as much about a company as the proposal document does.
Getting a fair comparison
If the proposals you have disagree about the cause, an independent measurement is the cleanest way to resolve it. A foundation evaluation records relative elevations, crack characteristics, moisture conditions, and drainage, and gives you findings you can hold each proposal against.
If the disagreement is complex, a licensed professional engineer’s independent report is another route — appropriate where the stakes are high, the situation is unusual, or a transaction depends on it.
