Uneven Front Porch or Stoop? We fix it fast.
Your front porch is one of the first things people see—and one of the most used areas of your home. If it’s starting to sink, tilt, or pull away from the house, it’s more than just a cosmetic issue.
It can become a safety risk.
It can affect how your door opens and closes.
And it usually gets worse over time.
Most homeowners don’t notice it right away. Then one day, the gap is bigger, the step feels off, or the porch just doesn’t look right anymore.
The good news is—you don’t have to tear it out to fix it.
Why Front Porches Sink in the First Place
Concrete porches sink for the same reasons as other slabs, but the impact can feel more serious because they’re connected to your home.
In most cases, the issue is below the surface of the stoop:
- Soil wasn’t compacted properly during construction
- Water slowly washes out the base underneath
- Freeze-thaw cycles cause the ground to shift
- Empty space (voids) forms under the slab
Once that support weakens, the porch starts to drop or separate from the structure.
Replacing the porch doesn’t fix what caused it to sink in the first place.
If your porch is sinking, there’s a good chance other areas around your home may be affected too. It’s common to see similar issues with garage floors, walkways and sidewalks, or nearby steps and patios. In some cases, the problem goes deeper, which is where void filling or soil stabilization may be needed to properly support the slab and prevent further movement.

Signs Your Porch Needs RepAIR
If you’re on this page, your porch may already be showing signs of movement:
- The porch has dropped on one side
- A gap is forming between the porch and the house
- Steps feel uneven or out of alignment
- Cracks are forming or getting worse
- The door above the porch doesn’t open or close smoothly
These are signs the slab is no longer supported evenly underneath.
Polyjacking: A Better Way to Fix Your Concrete
At Summit Pro Concrete Solutions, we lift and level your existing driveway using polyurethane foam. This concrete leveling process (also called polyjacking) works from below the surface to fix the real problem.
Step 1: Inspect & Drill
- Identify the problem areas underneath the slab
- Drill small, strategic holes to access below
Step 2: Lift & Stabilize
- Inject high-density poly foam under the concrete
- Lift the slab and fill empty space
- Stabilize the base to help prevent future sinking
Step 3: Patch & Finish
- Patch the small drill holes
- Clean the area
- Concrete is ready to use the same day in most cases
Concrete Lifting vs. Replacement
Most people assume replacing concrete is the only way to fix the problem—until they realize what that actually involves.
Here’s how the two options really compare:
Concrete Replacement
- Higher cost (often double or more)
- Takes days—or even weeks—to complete
- Loud, messy demolition and disruption
- New concrete can sink again if the soil isn’t fixed
Concrete Lifting (Polyjacking)
- Typically done in just a few hours
- Ready to use the same day
- Clean process with small drill holes
- Lifts your existing concrete and fixes the problem underneath
If your concrete is still in good condition, lifting is almost always the faster, cleaner, and more cost-effective way to fix it.
Small Movement Can Turn Into Bigger Issues
Porches are often connected directly to your home, which means even small movement can lead to more than just uneven concrete.
As the porch settles or shifts, it can begin to affect the areas around it—especially where it meets your home.
If left alone, it can:
- Increase the gap between the porch and the structure
- Put stress on steps, railings, and entry points
- Affect how doors open, close, or sit in the frame
- Lead to more visible cracking over time
- Allow water to collect or seep near the foundation
Most people wait because it doesn’t seem urgent at first—but once movement starts, it rarely corrects itself. The longer it’s left alone, the more the shift can impact surrounding areas.
Fixing it early helps protect not just your porch, but the entry point to your home—before it turns into a larger structural concern.
What You Get When It’s Fixed the Right Way
Concrete lifting isn’t just about making your porch look better—it’s about fixing the problem underneath so it stays level and supported.
When the job is done right, you get:
- A level, even porch again
- Proper support at your home’s entry point
- Reduced gaps between the porch and the structure
- Stabilized soil that supports the slab long-term
- A clean repair without tearing everything out
- Often half the cost of full concrete replacement
This isn’t a temporary patch—it’s a long-term fix that addresses the real cause of the problem.

Porch Leveling FAQ
Porches usually sink because the soil underneath shifts or washes away over time. This can happen from water drainage issues, poor compaction, or natural ground movement.
Yes. We use a controlled lifting process with polyurethane foam to gently raise the porch. The process is designed to avoid stress on the concrete and surrounding structure.
Most porch leveling jobs are completed in just a few hours, depending on the size and condition of the slab.
In many cases, yes. Lifting the porch back into position can reduce or close the gap. We’ll evaluate how much correction is possible during the estimate.
Yes. The foam creates a solid, stable base under the slab and is strong enough to support both residential and structural loads.
If the problem goes deeper, we may recommend soil stabilization or void filling to fully support the area.
We drill small holes to inject the foam, which are patched after the lift. These are minimal and blend in over time.
Yes. In most cases, lifting your porch is significantly more cost-effective than removing and rebuilding it.
Your porch is typically ready to use the same day. You can walk on it shortly after the repair is complete.
No. You can send photos, and we can often provide a quote without an in-person visit.
