A concrete lifting warranty covers the contractor's work — not a promise the ground will never move again. Here's what mudjacking and foam warranties typically cover, what's usually excluded, and the questions that separate real coverage from marketing.
A concrete lifting warranty is a workmanship promise: if the slab re-settles beyond an agreed amount within the warranty term, the contractor comes back and addresses it — typically a re-lift at no charge or reduced cost. That's it. It's not insurance, it's not a guarantee against nature, and it's not a promise that your soil will behave. It's the contractor putting their own work on the line for a defined period.
That distinction matters because it's the source of most warranty disappointment. Homeowners hear "warranty" and think "I'm covered no matter what." Contractors mean "I'm covered for my work." The gap between those two readings is where arguments happen — and the gap closes entirely when the terms are in writing, specific, and read before signing. This guide is about making sure you know what you're actually getting.
One framing that helps: a warranty is only as good as the contractor behind it. A written warranty from a licensed, established local company with a reputation to protect is worth something. The same words from a contractor who can't show you a license — well, there's nobody to enforce it against. Vetting the contractor and reading the warranty are the same job; see how to choose a concrete lifting contractor for the full checklist.
Legitimate concrete lifting warranties in the Salt Lake Valley generally cover three things:
The core of the warranty. If the lifted slab sinks again beyond a defined threshold (often around a half inch, though the number should be stated in your contract) within the warranty term, the contractor re-lifts it. This is the coverage you're really buying.
Foam that fails to cure or expand properly, slurry mix that crumbles — genuine material failures attributable to the product or its installation. Rare with established materials, but a real warranty names it.
An uneven lift, visible surface damage caused by the crew, injection ports left unpatched, cleanup not done. The "we'll make it right" category — and the easiest to claim, because it's visible on day one.
Notice what's doing the heavy lifting in that list: re-settlement coverage. That's the expensive scenario — paying for the same job twice — and it's the one that separates a real warranty from a feel-good paragraph. When you compare bids, ask each contractor specifically: "If this slab drops again in two years, exactly what happens?" The quality of that answer tells you more than the brochure does.
Warranty terms tend to track the method's weak points — which makes sense, since contractors warranty what they can control and hedge what they can't:
| Mudjacking | Polyurethane foam | |
|---|---|---|
| Typical term | Shorter — commonly a year or two of workmanship coverage | Often longer — foam's stability lets contractors stand behind it for more years |
| Why it differs | Slurry is heavy and can slowly re-settle on weak soil; it can erode if water keeps flowing underneath | Foam is lightweight and waterproof, so the two forces that undo mudjacking barely affect it |
| What to watch | Short terms are normal here — but the re-lift terms should still be clearly defined, not vague | Longer terms are common, but read the exclusions: a 5-year warranty that excludes "any settlement" covers nothing |
A few honest caveats. First, these are tendencies, not rules — an established mudjacking contractor may offer stronger terms than a fly-by-night foam outfit, and the contractor's stability matters more than the method's chemistry. Second, "typical" varies by company; there is no industry-standard warranty length, which is exactly why you get it in writing. Third, longevity and warranty are different things: how long a lift lasts depends on drainage, soil, and slab condition as much as on the material.
When a contractor quotes you, the warranty conversation should include the term length, the re-settlement threshold that triggers a claim, and who pays for what on a re-lift (labor, material, both?). If any of those three is vague, the warranty is vague.
Exclusions are where warranties live or die. These are the standard ones you'll see on legitimate concrete lifting warranties in Utah — none of them are unreasonable, but all of them should be disclosed before you sign:
The pattern: warranties cover the contractor's work, not the world's behavior. That's fair — as long as it's stated plainly. A warranty whose exclusions swallow its coverage ("excludes any settling of any kind") isn't a warranty; it's decoration.
Ask these during the estimate visit, and write down the answers. Then check that the written contract matches what you were told:
Think of it as two documents that travel together: the estimate is the price, and the warranty terms are part of the contract you sign. When you request estimates through our quote form, you're getting the pricing side — written, itemized estimates from local specialists, usually within one business day. The warranty side is what you evaluate during the follow-up conversation, using the questions above.
Here's how to use them together: when two bids are close on price, the warranty often decides. A bid that's a few hundred dollars more with a clear multi-year workmanship warranty, a defined re-settlement threshold, and a named claims process is usually the better value — because the thing you're most afraid of (paying for the job twice) is the thing it covers. Our published ranges give you the pricing context — mudjacking $3–$8 per square foot, polyurethane foam $5–$25 per square foot, most residential jobs $500–$3,000 — and the warranty gives you the risk context. You need both to choose well. See the cost guide for the full pricing breakdown.
Request free written estimates from local concrete lifting specialists, then use the questions above to compare warranty terms side by side. The best bid is the best combination of price and coverage.
A good warranty is specific, written, and boring: a defined term, a defined re-settlement threshold, clear re-lift terms, stated exclusions, and a claims process. It won't promise the impossible — no honest contractor guarantees the ground — but it does promise that the contractor stands behind their own work. That's exactly what you want, because the contractor's work is the part you can't inspect yourself.
Get the warranty in the contract, keep the paperwork with your before-and-after photos, and fix your drainage. Do those three things and a warranty claim becomes a phone call, not a fight.
Re-settlement beyond an agreed threshold within the warranty term — the contractor comes back and re-lifts the slab at no or reduced cost. It may also cover material defects (foam that fails to cure properly) and workmanship problems (an uneven lift, damage caused by the crew). What it does not cover is a promise the ground will never move again — no honest contractor guarantees the soil. See how long concrete lifting lasts for what determines longevity.
It varies by contractor and method, so get the exact term in writing. As a rule of thumb, mudjacking warranties tend to be shorter — the heavy slurry can slowly re-settle on weak soil — while polyurethane foam warranties often run longer, since foam is lightweight and waterproof. But the term on paper matters more than the method: a short written warranty beats a long verbal promise every time. Our mudjacking vs. foam guide covers how the methods differ.
Almost never. If your downspouts keep dumping water under the slab or the grade still slopes toward the house, re-settlement caused by that unresolved water is typically excluded — it's considered a new cause, not a failure of the original work. This is the most common warranty disappointment in Utah, and the reason estimates should address drainage alongside the lift itself.
Sometimes — it depends on the contractor. Some warranties transfer to the new owner automatically; others are void on sale or require a transfer notice and fee. If you're lifting concrete ahead of a sale, ask this question explicitly and get the answer in writing. A transferable warranty is a genuine selling point to buyers who notice the fresh lift.
Common void triggers: hiring someone else to re-lift or alter the slab, major drainage or grading changes you make after the job, structural modifications (adding heavy loads, new construction adjacent to the slab), and failing to maintain sealed joints if the contract requires it. Read the exclusions section of the warranty before you sign — it's usually short, and it's where the real terms live.
Be skeptical of extended warranties sold as add-ons. A contractor confident in their work includes meaningful coverage in the base price; a paid extension is often priced for profit, not protection. Compare the extension's actual terms — what's covered, who pays for a re-lift, what's excluded — against simply choosing the contractor with the better standard warranty. See how to choose a contractor for the full vetting checklist.
Document it — photos with a tape measure showing the drop, dated — then contact the contractor in writing (email counts) and reference the warranty terms in your contract. A legitimate contractor schedules an inspection and honors the re-lift terms. If they stall or deny, your written contract and documentation are what give you leverage. This is why "get it in writing" is the first rule: verbal warranties have no enforcement mechanism.
