What does driveway sealing cost in Ottawa per visit?

Professional driveway sealing in Ottawa typically costs $0.40 to $0.80 per square foot, which translates to $200 to $500 for an average residential driveway (400-600 square feet). Most Ottawa homeowners pay around $300 to $400 for professional sealcoating of a standard two-car driveway.

The cost varies based on several factors specific to your driveway's condition and size. Crack filling adds $150 to $500 to the total if your asphalt has cracks wider than 5mm that need hot-pour rubberized filler before sealing. Contractors typically charge a minimum service fee of $200 to $250 even for smaller driveways, making sealcoating more cost-effective on larger surfaces.

Ottawa's extreme climate makes sealcoating essential maintenance, not optional. With over 50 freeze-thaw cycles per winter and temperatures swinging from -30°C to +35°C throughout the year, unsealed asphalt deteriorates rapidly. Water penetrates the asphalt surface, freezes and expands, then thaws and allows deeper penetration with each cycle. Road salt applied from November through April accelerates this process by promoting oxidation and brittleness in the asphalt binder.

Professional contractors in Ottawa use asphalt emulsion sealers specifically formulated for Canadian freeze-thaw conditions. The sealer must be applied when temperatures are consistently above 15°C with no rain forecast for 24-48 hours, limiting the application window to late May through early September in most years. Two thin coats applied with commercial squeegees provide better coverage and durability than one thick coat.

DIY sealcoating costs $0.15 to $0.35 per square foot for materials if you handle the work yourself. A 5-gallon bucket of quality asphalt emulsion sealer costs $25 to $40 and covers approximately 250-300 square feet. You'll also need crack filler ($15-25 per tube), a squeegee or roller ($20-40), and cleaning supplies. However, professional application typically lasts 3-4 years versus 2-3 years for DIY work due to proper surface preparation and application technique.

Timing your sealcoating every 2-3 years is critical in Ottawa. Waiting longer allows UV rays, water, and salt to penetrate deeper into the asphalt structure, causing oxidation and brittleness that sealer alone cannot reverse. Once asphalt begins showing alligator cracking or significant raveling, it's beyond the help of sealcoating and requires patching or resurfacing.

The investment in regular sealcoating extends your driveway's lifespan from 12-15 years (unsealed) to 20-25 years (properly maintained), making it the most cost-effective maintenance you can perform on an Ottawa asphalt driveway.
