The Questions That Separate an Honest Leveler From a Sales Pitch

1. What's Actually Causing My Slab to Sink?

These seven questions separate a real diagnosis from a sales pitch - a straight Kansas City contractor should be able to answer every one on the spot. They're the questions to ask during the call or on-site visit; for the broader vetting checklist, see how to choose a concrete leveling company. Start with the cause:

This is the question that separates a real diagnosis from a generic sales pitch. In the Kansas City area, common causes include expansive clay soil that swells and shrinks with moisture, freeze-thaw cycling through winter, and poor drainage from downspouts or grading that washes soil out from under a slab. A contractor who's actually looked at your property should be able to point to which of these - or which combination - applies to your driveway, patio, or steps, not just say "concrete settles over time." If you want a primer before the visit, our page on why concrete sinks in Kansas City covers the main causes we see most often across the metro.

3. How Many Holes, and How Big?

This tells you a lot about the method and the disruption to expect. Polyurethane foam injection typically uses a handful of dime-sized holes, since the foam expands significantly once it's injected. Mudjacking generally requires larger holes to pump through a heavier slurry. Neither is inherently wrong, but you should know what you're signing up for before the crew shows up. Ask specifically where the holes will be placed, especially on a visible surface like a front walkway or patio, and how they'll be patched afterward once the lift is complete.

4. How Long Until I Can Actually Use the Area Again?

Downtime matters, especially for a driveway you use daily or steps at your main entry. With foam injection, the cure happens within minutes, so light foot traffic is often possible in about 15 to 30 minutes, with vehicle use following in roughly 1 to 2 hours. That's a meaningful difference from methods that need longer to set up or cure. Ask for a specific, realistic timeline for your job rather than a vague "later today" - a contractor who's done this enough times should be able to tell you exactly what to expect for your driveway, patio, or garage floor.

5. Will This Address the Void, or Just Raise the Slab?

These sound similar but aren't quite the same thing. Simply lifting a slab back to level doesn't necessarily mean the space underneath is fully filled - if there's still an empty pocket where soil eroded or settled, the slab can be prone to sinking again. Ask whether the process is filling the actual void, not just pushing the concrete up. Void filling exists as its own service precisely because some slabs have gaps underneath that haven't caused visible sinking yet, and addressing those proactively is part of doing the job thoroughly rather than just cosmetically.

6. Do You Actually Work in My Part of the Metro?

Service area matters more than it might seem - a company based far from you may be less familiar with your specific soil and drainage conditions, or may treat your job as a lower scheduling priority. Ask directly whether they regularly work in your city, whether that's Overland Park, Lenexa, Olathe, Lee's Summit, Independence, or elsewhere across Johnson or Jackson County. PolyJacks is based in Spring Hill, Kansas, and covers the full Kansas City metro on both the Kansas and Missouri sides, so this is a reasonable thing to confirm with anyone you're considering.

7. Is the Estimate Free, and Will I Feel Pressured to Sign Today?

A free estimate should mean exactly that - someone comes out, looks at the slab, and gives you a straight read on the cause and the fix, with no cost and no obligation. Ask upfront whether there's any pressure tactic involved, like pricing that "expires" if you don't commit on the spot. A contractor confident in their diagnosis and reputation - PolyJacks is proud of our five-star service - shouldn't need a countdown clock to get you to say yes. Take the time you need to compare answers before deciding who does the work.
