Review a polyjacking slab quote example and learn what to ask about voids, foam, lift targets, and warranty.
Check Your QuoteSinking slab lift
Drill injection ports and lift sunken slab area with polyurethane foam. Approx. 220 sq ft. Total: $4,600.
$4,600 can be reasonable for a defined slab lift, but the quote should explain why the slab sank and how re-settlement is handled.
Line-by-line review
| Item | In this example | Why it matters |
|---|---|---|
| Scope label | Sinking slab lift | A useful quote should name the actual repair method instead of hiding the work inside a package name. |
| Price signal | $4,600 can be reasonable for a defined slab lift, but the quote should explain why the slab sank and how re-settlement is handled. | The total price only becomes meaningful after quantities, locations, exclusions, and warranty boundaries are known. |
| Highest-risk wording | No foam density | This is the first phrase or missing detail to slow down and clarify before signing. |
| Most important missing item | Lift tolerance | Ask for this in writing so another contractor can compare the same scope. |
| First homeowner question | What caused the void? | A clear answer should appear in the revised proposal, not only in a sales conversation. |
Scope review
A useful foundation repair quote should connect the observed problem to the proposed method. For this example, the contractor should explain why the listed scope fits the home, how the repair quantity was chosen, which conditions could change the final price, and which parts of the home are excluded from the warranty. If the written proposal cannot answer those points, the price may be hard to compare even when the total looks reasonable.
The quote names a project type and gives a total price, which is better than a verbal estimate. It also gives enough language to start a comparison with another contractor. The next step is to make the scope measurable: locations, quantities, material names, installation assumptions, warranty boundaries, and payment timing should all be written into the proposal before signing.
The biggest risk is not always the dollar amount. It is the gap between what the homeowner thinks is included and what the contractor is obligated to perform. In this sample, pay special attention to no foam density, lift tolerance, and whether the warranty follows the repaired area, the whole foundation, or only a specific material.
Ask for a final written scope, drawing or marked photos, warranty document, payment schedule, exclusions, permit responsibility, and any engineer or plumbing notes that affect the work. Keep the signed contract, invoice, before-and-after photos, and warranty certificate in one folder in case you sell the home or need a future claim.
Better written scope
A safer written version of this sinking slab lift quote would keep the total price visible, but it would also define the scope tightly enough that the homeowner can compare another bid. At minimum, it should answer the questions below before the contract is signed.
Homeowner decision path
Do not judge the sinking slab lift quote by price alone. Start with the diagnosis and written scope.
Ask the contractor to revise the proposal so it addresses lift tolerance and foam specification.
Get a second written bid or independent review when the scope is expensive, structural, warranty-heavy, or tied to water and soil conditions.
Keep the final scope, drawings or photos, warranty, change orders, payment receipts, and completion documents together.

The site explains when to involve a structural engineer, licensed contractor, insurer, building department, or attorney.
Compare the sample language against your written proposal before comparing price. The goal is to understand whether the quote explains the diagnosis, repair quantity, warranty, exclusions, and payment terms clearly enough to sign.
If your contractor uses similar wording but leaves out quantities or repair locations, ask for an updated written scope. A clear quote should make it possible to compare another contractor's bid item by item.
Treat this example as educational guidance, not a price guarantee. Local soil, access, permits, engineering, drainage, plumbing risk, and finished-surface repairs can all change the final project cost.
Use it as a scope checklist, not a final price benchmark. Local inspection findings, repair quantities, access, soil, permits, drainage, and warranty terms can change the cost.
Ask for the diagnosis, repair locations, material names, quantities, warranty terms, exclusions, payment milestones, permit responsibility, and what could change the final price.
Get another written estimate or an independent engineer review when the quote is expensive, the diagnosis is vague, contractors disagree, or the repair involves structural movement.
Not automatically, but the contractor should revise the proposal before you sign. You need enough written detail to compare scope, warranty, exclusions, and payment terms.
Yes. A simple drawing, marked photo, pier layout, drain route, crack location, or crawl space diagram makes the quote easier to compare and helps prevent confusion during the job.
Payment should usually track clear milestones such as scheduling, material delivery, installation progress, inspection, or completion. Be cautious when a large deposit is paired with vague scope language.
Paste your actual quote into the checker and compare the output against this example. Pay special attention to vague quantities, excluded work, warranty language, and payment milestones.
