Asphalt Repair & Pothole Patching in Sonoma & Marin County
A pothole or a spreading crack doesn’t fix itself — it gets worse. Water gets into the gap, freeze-thaw cycles and vehicle weight widen it, and what started as a small problem turns into an expensive one. A&L Asphalt has repaired driveways and commercial lots across Sonoma, Marin, and Lake County for over 24 years, and we know how to fix damage the right way instead of just covering it up.
What Causes Potholes and Cracking
Most asphalt damage starts the same way: water gets underneath the surface, usually through a small crack, and weakens the base. Vehicle weight then breaks down the compromised area, and the problem grows fast, especially with repeated freeze-thaw cycles or consistent heavy traffic. By the time a pothole is visible, the base underneath is often already damaged, which is why a proper repair addresses more than just the surface.
Our Asphalt Repair Process
Assessment
We inspect the damaged area and the surrounding asphalt to understand how far the problem extends, not just the visible pothole or crack.
Removing damaged material
We cut out and remove the compromised asphalt and any weakened base material underneath.
Base repair
If the base has failed, we repair and properly compact it before adding new asphalt. Skipping this step is why some pothole "repairs" fail again within months.
Patching
We apply new asphalt to the repaired area, compacted and finished to blend with the surrounding surface as closely as possible.
Crack sealing
For cracks rather than full potholes, we seal the crack to prevent water intrusion and stop it from spreading further.
When Repair Makes Sense vs. Full Replacement
Types of Asphalt Repair We Handle
Pothole patching for isolated damage from water intrusion and vehicle weight. Crack sealing for surface cracks before they widen into bigger problems. Alligator cracking repair for the web-like cracking pattern that signals base failure underneath a larger area. Edge repair for crumbling along driveway or parking lot borders, which is common where asphalt meets grass, gravel, or landscaping.
Commercial Property Owners: Why Fast Repair Matters
For commercial properties, a pothole isn’t just an eyesore — it’s a liability. Vehicle damage claims, trip-and-fall risk for pedestrians, and general property appearance all suffer when damage sits unaddressed. We prioritize repair requests for active safety concerns and can typically schedule an assessment quickly.
What Affects the Cost of Asphalt Repair
Cost depends on the size and depth of the damage, whether the base needs repair in addition to the surface, and how many separate areas need attention. A single small pothole costs far less to fix than a lot with alligator cracking spread across a large section. We provide free estimates so you know the real cost before any work begins.
