Driveway Sealing London, Ontario

Asphalt in London lives a hard life. Every winter, road salt tracks up from the street, meltwater seeps into hairline cracks, and overnight freezes pry those cracks wider. Every summer, UV bakes the surface grey and brittle. Professional driveway sealing in London, Ontario is the cheapest insurance your driveway can get: a properly prepped and sealed surface sheds water, resists salt damage and stays jet black, often doubling the time before you face a five-figure repaving bill.

Why Sealing Matters in Our Climate

Asphalt fails from the inside out. Once water gets into a crack and freezes, it expands roughly 9% — turning a hairline into a gap, a gap into an alligatored patch, and a patch into a pothole. London averages dozens of freeze-thaw cycles per winter, which is why an unsealed driveway here ages two or three times faster than the same surface in a milder climate. Sealing every two to three years keeps water out, restores the flexible oils UV strips away, and gives the whole property an immediate facelift.

Our Process, Start to Finish

We start with a complete clean — power blowing, scraping embedded debris and trimming grass edges that have crept over the asphalt. For driveways with heavy grime or oil spotting, a pressure wash beforehand gives the sealant its best possible bond. Cracks get filled and levelled, oil stains primed so the sealer adheres, then we apply sealant evenly across the surface and tape off the entrance. Most driveways need 24 to 48 hours before vehicle traffic; we'll tell you exactly when you can park again based on the weather that week.
