Pothole repair and asphalt patching in St. Louis opens up every spring, when the freeze-thaw cycle of winter breaks the base under worn pavement and water works into cracks that turn into holes overnight. The clay and loess soil beneath most of the city and county swells when wet and shrinks when dry, moving whatever sits on top of it. That ground movement, combined with more than a hundred freeze-thaw crossings in a typical St. Louis winter, cracks asphalt from below and breaks it apart from the surface down. Once a pothole opens, it grows fast. We saw-cut the damaged area, remove wet and failed base material, compact new aggregate, and lay hot mix flush with the surrounding pavement. The work is straightforward, the results are durable when done right, and the cost is a fraction of what a full asphalt resurfacing or replacement would run.
Why Potholes and Pavement Cracks Demand Fast Repair in St. Louis
A pothole is not just a cosmetic problem. Once the surface breaks and water reaches the base, the failure accelerates. Every vehicle that hits the edge of the hole breaks more asphalt away, and water pooling in the base weakens the aggregate underneath. In St. Louis, where the ground shifts with the seasons, a small crack becomes a pothole in weeks, and a pothole becomes a section of failed pavement in months. The longer you wait, the more base material you lose, and the bigger the patch has to be to hold.
- We identify the full extent of the failure beneath the surface before we cut, so the patch includes all the damaged material.
- Proper base compaction is the difference between a patch that holds for years and one that fails again in a season.
- Hot mix laid at the right temperature and compacted flush with the surrounding surface bonds properly and sheds water instead of trapping it.
- Early repair stops the spread and costs far less than waiting for the failure to grow into a resurfacing job.
Catching potholes and cracks early is the single most cost-effective move a homeowner or property manager can make in St. Louis.
Local example: A driveway in Ferguson or Kirkwood with three or four isolated potholes is a pothole repair job. A driveway in Clayton or Webster Groves where potholes cover thirty percent of the surface is a resurfacing candidate, because patching throws money away and the base is already compromised across the entire drive.

How We Repair Potholes and Patch Asphalt in St. Louis
The work starts with a clear boundary. We saw-cut the damaged asphalt in a clean rectangle or square, removing the guesswork and leaving a solid edge for the new patch to bond to. Then we excavate the failed base material, proof-roll the subgrade to confirm it is stable, and compact new aggregate to the proper density. The final step is laying hot mix asphalt at the correct temperature and compacting it flush with the surrounding pavement so water runs off instead of pooling.
- We saw-cut a clean perimeter around the damaged area so the new asphalt bonds to solid pavement, not to crumbling edges.
- We remove all wet, soft, or failed base material and replace it with compacted aggregate that meets local specifications.
- We lay hot mix at the right temperature and compact it to density, so the patch becomes part of the pavement instead of a weak spot.
- The finished patch is flush with the surrounding surface and sheds water the way the original pavement does.
This process works for isolated potholes, spalling, edge breaks, and alley approaches where the street meets the driveway.
Real St. Louis scenario: An alley approach in the city grid where the driveway meets the street is a common failure point. The city owns the apron, and we handle the patching as part of your driveway work. Permits and HOA rules vary across the county, so we always defer to the local building department and any architectural guidelines that apply to your property.

Pothole Repair Methods and Approaches
| Approach | Description | Best For |
|---|---|---|
| Full-Depth Patch | Saw-cut perimeter, remove asphalt and base, compact new aggregate, lay hot mix to original thickness. | Potholes, edge breaks, alley approaches, any failure that reaches the subgrade. |
| Partial-Depth Patch | Remove only the damaged asphalt and top portion of base, compact and lay new hot mix without disturbing lower base layers. | Shallow spalling, surface cracks that have not yet opened the base, and areas where the lower base is still sound. |
| Throw-and-Roll | Cold-mix temporary fill compacted into the hole and rolled flush, holding until a proper hot-mix patch can be scheduled. | Emergency repairs on busy lots, temporary fixes in winter when hot mix cannot be laid, or holding a failure until spring. |
| Saw-Cut Edge Repair | Clean saw-cut along the edge of an alley or driveway apron where it meets the street, remove damaged material, compact base, lay hot mix to match the street profile. | Broken aprons, edge spalling where the driveway meets the street or parking lot, and transitions between surfaces. |
The method we choose depends on the depth of the failure, the condition of the base beneath it, and how much of the surrounding pavement is still sound. We assess every site before we quote.
Pothole Repair and Asphalt Patching Cost in St. Louis: What to Expect
Pothole repair in St. Louis typically starts at around $450 for a single isolated pothole, including saw-cutting, base removal and replacement, and hot mix asphalt. The cost rises with the size of the failure, the depth of the base damage, and how many patches are needed. A driveway with two or three potholes costs more than one with a single hole. A parking lot with scattered failures across a large area may justify resurfacing instead of multiple patches, because the cost per square foot of a full resurface becomes competitive once the damage is widespread.
Several factors move the price:
- Size of the pothole or damaged area: larger patches require more material and longer labor time.
- Depth of base failure: if we find soft or saturated material below the asphalt, we remove more and replace it, increasing cost.
- Number of patches: multiple isolated failures cost less per patch than a single large one, but the total rises with each additional repair.
- Access and site conditions: tight driveways in the city, alley approaches, or parking lots with obstacles may take longer to set up and work around.
- Timing: emergency or same-day repairs carry a premium; scheduling work in advance keeps costs down.

Pothole Repair and Asphalt Patching Near Me: What to Look for When Hiring a Contractor in St. Louis
The paving trade in St. Louis has a long history with door-to-door crews offering "leftover asphalt from a job nearby" at a price that sounds too good. The honest way to verify any contractor is to check how they work: a legitimate local shop will provide a written estimate with tonnage and thickness, will explain what material is going in and why, will give you a timeline, and will show you proof of insurance. We are fully insured, and we work from a local address with local plates. We do not take large cash deposits, and we do not require payment until the work is done.
When you are comparing contractors for pothole repair and asphalt patching in St. Louis, Clayton, Kirkwood, Webster Groves, Ferguson, or anywhere in the county:
- Verify that the contractor is insured and ask to see a current certificate of insurance covering the work you need.
- Get written estimates from at least two contractors, and compare the tonnage, thickness, and materials listed, not just the price.
- Ask for references from recent jobs in your neighborhood or similar properties, and follow up with at least one.
- Check whether your municipality or HOA requires a permit for the work, and confirm the contractor will help you navigate local requirements.
- Avoid any contractor who asks for a large deposit upfront, quotes a price per square foot without seeing the site, or cannot provide a written contract.
