Driveway Sealing

Ottawa's extreme climate puts asphalt driveways through punishing freeze-thaw cycles, with temperatures swinging from -30°C in January to +35°C in July. Professional driveway sealcoating creates a protective barrier that shields your asphalt from water penetration, UV degradation, and the corrosive effects of road salt and chemical de-icers used heavily throughout the capital's long winters.

Without regular sealing, water seeps into micro-cracks, freezes, expands, and progressively breaks apart the asphalt surface — a process that accelerates rapidly given Ottawa's 150+ freeze-thaw cycles per year. A quality sealcoat application fills minor surface imperfections, restores the rich black appearance of your driveway, and extends its lifespan by five to eight years between major repairs.

Ottawa's short paving season means scheduling is critical — sealcoating requires dry conditions and temperatures above 10°C, limiting the window to roughly May through early October. Our Ottawa driveway sealing contractors use commercial-grade coal tar or asphalt emulsion sealers applied in two coats, with proper crack filling completed beforehand so the seal is comprehensive.

Many neighbourhoods across Ottawa, from Barrhaven to Orleans to Kanata, see significant snow plow damage each winter that strips away unprotected asphalt. Regular sealcoating every two to three years is the most cost-effective maintenance strategy to protect your investment and avoid costly full repaving down the road.
