From the heritage streets of Unionville to the new subdivisions of Cornell, Markham homeowners fight the same enemy every year: winter. Freeze-thaw cycles, road salt and spring meltwater work into unsealed asphalt and turn small cracks into expensive repairs. Professional driveway sealing every 2–3 years keeps Markham driveways protected — and looking sharp.
Markham driveways: what we see most
Markham’s mix of housing means a mix of driveways. The 1980s–2000s subdivisions around Milliken, Greensborough and Box Grove are full of double-car asphalt driveways now due for their second or third seal. In Unionville and older pockets, mature trees are beautiful — but root pressure and heavy shade (which slows curing) need an experienced eye. And in Cornell and other newer developments: if your asphalt is less than a year old, give it one full season to cure before sealing.

Markham driveway sealing FAQs
How soon after paving should I seal a new driveway?
Wait 6–12 months. Fresh asphalt needs time to cure and release its natural oils — sealing too early traps them and the sealer won’t bond properly. If your Cornell or new-build driveway was paved this year, book for next season.
Does road salt damage a sealed driveway?
Far less than bare asphalt. Sealer forms a barrier against salt and de-icing chemicals, but it’s still smart to rinse the driveway in spring to wash away the winter’s residue.
How much does driveway sealing cost in Markham?
A typical double-car driveway in the GTA runs $250–$400. See our driveway sealing cost guide for full ranges, or request a free quote for your exact price.
