Asphalt & Pothole Repair: what it is, and when it matters
Most asphalt repair on driveways and parking lots comes down to the same problem: a spot where the surface has failed. Potholes are what happens when water, freezing temperatures and traffic find a weak spot. The pavement cracks, water gets in, the base softens, and the surface collapses. Filling just the hole does not fix any of that.
A repair that lasts starts by cutting the hole back to sound pavement with square, vertical edges. We remove the loose material, check and rebuild the base if it has failed, brush a tack coat on the sides and bottom so new asphalt bonds, then place hot mix in layers. Each layer is compacted before the next goes on. The patch is finished flush and sealed at the seam so water cannot get back in.
In the coldest months, hot mix is generally not available. We can place cold patch as a temporary fix to keep a hole from getting worse, and return in spring for a permanent repair. We will tell you honestly when a patch is the wrong answer and the better move is a larger repair or an overlay.

Questions for Lines & Asphalt
Asphalt & Pothole Repair FAQ
Do you repair asphalt driveways, or just parking lots?
Both. Driveway repair is a big part of our work: potholes near the garage, crumbling edges, soft spots and sunken areas. The method is the same as on a parking lot, cut back to sound asphalt, fix the base and patch with hot mix.
How is pothole repair priced?
By the number of holes, their depth and the condition of the base underneath. We look at the holes and give you a free written price before any work starts.
Why do you cut the hole bigger?
The edges of a pothole are weak. Cutting back to sound pavement gives the patch something solid to bond to.
What is the difference between cold patch and hot mix?
Cold patch is for emergency winter repairs. Hot mix is a permanent repair and is used when temperatures allow.
Will the patch match my driveway?
A fresh patch is black and will blend over time. Sealcoating the whole driveway makes everything uniform.
Can you fill the cracks around the pothole too?
Yes. That is often the smart move. Fixing the cracks stops the next pothole from forming.
