We have a massive pothole forming in our driveway in January — can anything be done in winter?

Emergency Winter Pothole Repair Is Possible but Temporary

You are not stuck waiting until spring. Winter pothole repairs in Ottawa use cold-mix asphalt, which is specifically designed to be applied in freezing temperatures. While it is not a permanent fix, it can prevent the pothole from growing larger and becoming a safety hazard or causing vehicle damage during the remaining winter months.

How Cold-Mix Repair Works

Cold-mix asphalt comes pre-mixed and does not require heating. A contractor cleans out the pothole as best as possible given the conditions, fills it with cold-mix material, and compacts it. The patch bonds through a chemical curing process rather than heat, so it can be applied even when temperatures are well below freezing. Some Ottawa contractors use infrared asphalt heaters for a more durable winter repair — this technology heats the existing asphalt around the pothole to bond with new hot-mix material, creating a much stronger patch even in cold weather.

What to Expect in Terms of Durability

A standard cold-mix patch is meant to last through the winter as a temporary measure. It will likely need to be replaced with a proper hot-mix repair once asphalt plants open in spring, typically late April or early May in the Ottawa area. An infrared repair is more durable and may last a full season or longer. The key is preventing water from entering the pothole and freezing, which would rapidly enlarge it through each freeze-thaw cycle.

Cost for Winter Emergency Repairs

A cold-mix pothole fill for a single pothole typically costs between $150 and $400 for a contractor visit. Infrared repair is more expensive at $300 to $700 per patch but offers significantly better longevity. Many Ottawa driveway contractors in Stittsville, Kanata, and across the city offer winter emergency service, though availability can be limited during extreme cold snaps below -25°C.

DIY as a Stopgap

If you cannot get a contractor out immediately, bags of cold-mix asphalt are available at hardware stores for $20 to $40 per bag. Clean out loose debris, fill the hole slightly above grade, and compact it firmly with a tamper or even your car tire. This will hold temporarily but should be professionally addressed in spring.

Planning the Permanent Fix

Book your spring repair early — Ottawa contractors fill their schedules quickly once the season starts. A permanent hot-mix repair of the same pothole will cost $300 to $600 and should include inspecting the base for the underlying cause.

Reach out through Ottawa Driveways to find contractors who offer winter emergency driveway repair and can schedule your permanent spring fix at the same time.
