# DIY concrete leveling vs hiring a pro

What you can genuinely fix yourself, what DIY products only hide, and where a professional lift is the only real fix.

By New Orleans Concrete Leveling · Updated September 24, 2026

DIY products **resurface or fill** concrete; they don't **lift** it. Self-leveling compound fixes small, stable dips indoors, and resurfacers smooth a worn surface, but neither fills the void under a sunken slab. For a slab that has dropped, a professional lift with **mudjacking ($4–$9/sq ft) or foam ($8–$25/sq ft)** is the fix that addresses the cause.

[New Orleans Concrete Leveling](https://concretelevelingneworleans.com/) is happy to tell you when you don’t need a contractor. Here’s what DIY products actually do.

## What DIY products do — and don’t

| Product | What it does | What it can’t do |
| --- | --- | --- |
| **Self-leveling underlayment** | Flattens small, stable dips on interior floors before new flooring | Lift a slab or fill a void under it |
| **Concrete resurfacer** | Smooths a worn or scaled surface | Fix a drop, a lip or lost support |
| **Crack filler and joint sealant** | Keeps water out of cracks and joints | Close a gap caused by movement |
| **Small DIY foam kits** | Fill a small, accessible void | Control a lift across a whole panel |

The common thread: a sunken slab has **lost support underneath**. Toppings sit on top; the void stays, the slab keeps moving, and the topping cracks.

## Where DIY is the right call

-   **Water control.** Extend downspouts, regrade soil away from slab edges, clear drains. This is the single most useful thing you can do in New Orleans, with more than 60 inches of rain a year ([NWS](https://www.weather.gov/lix/newnormals)).
-   **Sealing joints and cracks** with a flexible sealant.
-   **Small interior dips** before flooring, if the slab isn’t actually settling. For a settled slab, see [floor leveling before tile installation](https://concretelevelingneworleans.com/slab-leveling-before-flooring/).

## Where DIY usually backfires

-   **Toppings over sunken outdoor slabs.** They add weight, hide the void, and crack.
-   **Trying to lift with consumer foam.** Over-lifting cracks slabs; under-filling leaves voids; foam in the wrong place can push up nearby slabs.
-   **Anything near foundations, pools or plumbing** without knowing what’s underneath.

## The professional options and their costs

[Mudjacking](https://concretelevelingneworleans.com/mudjacking/) runs about **$4–$9 per square foot** and [polyurethane foam](https://concretelevelingneworleans.com/polyurethane-foam-leveling/) about **$8–$25**, with a **$300–$700 minimum** ([HomeGuide](https://homeguide.com/costs/mudjacking-cost)). For small jobs the minimum dominates, so bundle every sunken area into one visit. See the [cost guide](https://concretelevelingneworleans.com/guide/concrete-leveling-cost-new-orleans/).

## Bottom line

**DIY can control water and smooth surfaces; it can’t lift a sunken slab.** For a real lift, call **[(504) 517-8336](tel:+15045178336)** — free estimate within 24 hours.

## Quick answers

### Can I use self-leveling compound on a sunken driveway?

It won't fix a sunken slab. Self-leveling compound is mostly an interior underlayment; outdoors, a topping over a sunken panel adds weight, leaves the void, and tends to crack as the slab keeps moving.

### Are DIY foam leveling kits worth it?

Small consumer foam kits exist, but controlling a lift without the right equipment risks over-lifting, cracking the slab or filling the wrong space. For anything larger than a small void, the risk usually outweighs the savings.

### What can I do myself?

Extend downspouts, regrade soil away from slab edges, seal joints and cracks, and fill small interior dips with self-leveler before flooring. Those steps also help a professional lift last.
