How much for hot crack sealing on my Ottawa driveway?

Hot-pour crack sealing in Ottawa typically costs $2 to $5 per linear foot professionally applied, with most residential driveways requiring $150 to $500 worth of crack filling depending on the extent of cracking.

Hot-pour crack sealing is one of the most cost-effective maintenance investments you can make for an Ottawa asphalt driveway. Unlike cold-pour crack fillers that you can buy at hardware stores, hot-pour sealant is heated to 180-200°C and applied with professional equipment, creating a flexible seal that moves with your driveway through Ottawa's brutal freeze-thaw cycles. The material remains pliable at -30°C and won't crack out during our harsh winters like rigid fillers do.

The process involves cleaning debris from cracks, applying the hot sealant with a pour pot, and smoothing it level with the surface. Cracks wider than 25mm may require backer rod installation first to prevent the sealant from sinking too deep. Professional contractors use rubberized hot-pour sealants specifically designed for Canada's climate - these contain polymers that maintain flexibility through temperature swings of 60+ degrees that Ottawa experiences annually.

Timing matters significantly in Ottawa. Hot crack sealing should be done when ambient temperatures are consistently above 10°C and the forecast shows no rain for 24 hours. This typically means May through October in our climate. The work should be completed before sealcoating - fill the cracks first, then apply sealer over the entire surface for maximum protection.

For an average Ottawa driveway with moderate cracking (20-40 linear feet of cracks), expect to pay $200-400 for professional hot-pour crack sealing. Driveways with extensive alligator cracking or settlement cracks may need $500-800 worth of work. If your driveway has more than 100 linear feet of cracking, it may be approaching the point where resurfacing or replacement becomes more economical than repairs.

Hot-pour crack sealing lasts 3-5 years in Ottawa's climate when properly applied, compared to 1-2 seasons for cold-pour DIY fillers. The investment pays for itself by preventing water infiltration that causes potholes, base failure, and the need for expensive asphalt replacement. Water entering cracks and freezing is the primary destroyer of Ottawa driveways - proper crack sealing stops this cycle.

When to Hire a Pro: Hot-pour crack sealing requires specialized heating equipment (melter/applicator) that costs $3,000-8,000, making it impractical for DIY. The sealant must be applied at precise temperatures and the equipment requires training to operate safely. Professional contractors also have access to commercial-grade rubberized sealants that aren't available to consumers.
