Cold patch costs a few dollars per 50-pound bag, and one bag fills roughly 2 square feet at a 2-inch depth. A contractor pothole repair costs $100 to $400 each, because the price is labor and preparation rather than material. The gap between those two numbers is the whole story of cold patch: cheap to buy, temporary by nature, and priced for a job that is measured in months rather than years. Budget it as a stopgap and the numbers make sense; budget it as a repair and they never will.

## What cold patch is

Cold patch is a bagged asphalt mix that can be placed without heating, using solvent-cut binder that cures slowly in place.

It is designed for temporary repair, especially in cold or wet weather when hot-mix plants are closed. It bonds mechanically, not chemically, which is why it ravels at the edges and sinks over time.

That is not a defect. It is the trade-off that makes the product usable in February.

## Material cost by pothole size

| Pothole | Area | Depth | Bags at 2 in | Material |
| --- | --- | --- | --- | --- |
| Small | 1 sq ft | 2 in | 1 | A few dollars |
| Medium | 2 sq ft | 2 in | 1 | A few dollars |
| Large | 4 sq ft | 2 in | 2 | Under $20 |
| Wide and deep | 6 sq ft | 4 in | 6 | Under $50 |

The arithmetic behind the coverage: a 50-pound bag is about 0.35 cubic feet of mix. At a 2-inch depth, 0.35 ÷ 0.167 = about 2 square feet.

A 4-inch deep hole of the same area needs twice the material, which is why depth matters more than the footprint when you are buying bags. Measure both before you drive to the store, and round the bag count up rather than down: a patch that runs short mid-lift has to be dug out and redone.

## The contractor price, explained

A pothole repair at $100 to $400 each is not $400 of asphalt. It is a sequence of steps.

Saw-cutting the edges square, so the patch has vertical walls to key against. Removing loose material and any failed base. Adding and compacting aggregate where the base has hollowed out. Placing hot mix in lifts and compacting each one. Sealing the joint.

On a $250 patch, material might be $30 and the rest is labor, equipment, and travel. That is also why small patches on distant jobs price at the top of the band.

## DIY versus contractor, honestly

| Approach | Cost | Life | Best for |
| --- | --- | --- | --- |
| Cold patch, DIY | A few dollars per bag | One season to a few years | Winter stopgap, small holes |
| Cold patch, hired | $100-$400 per pothole | One season to a few years | Not usually worth hiring |
| Hot-mix patch | $100-$400 per pothole | Several years | Permanent repair |
| Overlay | $3-$7 per sq ft | 10-15 years | Widespread surface failure |

Hiring out a cold-patch repair rarely makes sense, because the labor exceeds the value of a temporary fix. Hiring out a hot-mix patch does make sense, because the durability comes from the material and the compaction.

DIY cold patch makes sense in one situation: a hole that appears in winter and needs to be safe until spring. It is a stopgap, priced like one.

## Cold patch against the bigger numbers

A 600 square foot driveway with two potholes:

Cold patch DIY: two bags, under $20, lasting one season.
Hot-mix patching: 2 × $100 to $400 = $200 to $800, lasting several years.
Overlay: 600 × $3 to $7 = $1,800 to $4,200.
Replacement: 600 × $8 to $15 = $4,800 to $9,000.

If potholes keep returning in the same spot, the pattern points to a base problem. Cold patch and hot patch both fail there, because the hole is being re-opened from underneath. Our [potholes repair](https://drivewaysealinglab.com/potholes-repair/) guide covers that diagnosis.

## When cold patch is the right buy

Three situations justify it.

Winter emergencies. A hole that could damage a tire needs filling now, and hot mix is not available.

Temporary access. A rental property or a driveway scheduled for replacement needs to be safe for a season.

Testing a repair. Filling a hole temporarily shows whether the base holds before committing to a permanent patch.

Outside those, cold patch is a delay rather than a repair. It is honest about that on the bag, and the price reflects it.

## What a permanent repair costs

A permanent pothole repair uses hot mix, a squared edge, a compacted base, and proper lift thickness. That is the $100 to $400 per pothole band.

Where potholes cover a large share of the surface, an overlay at $3 to $7 per square foot is more economical than patching piece by piece. On 600 square feet, an overlay is $1,800 to $4,200 against $200 to $800 for a couple of patches, so patching wins until the damage is widespread.

Replacement at $8 to $15 per square foot is the last resort, and it is the right one when the base has failed across the driveway.

## A five-step buying decision

1. Measure the pothole area and depth.
2. Decide whether you need a stopgap or a repair.
3. For a stopgap, buy bags at the coverage rate above and place them in lifts.
4. For a repair, get quotes for hot-mix patching at $100 to $400 per hole.
5. If more than a quarter of the surface is broken up, price an overlay instead.

The most expensive mistake is buying cold patch repeatedly for a hole that keeps reopening. At some point the annual spend exceeds a permanent repair.
