Royal Sealing seals Markham driveways — newer Cornell and Berczy subdivisions plus historic Unionville — driveways kept to a high standard. Free on-site quote, same-day reply.
Same-day reply. No obligation. We'll come measure your driveway.
Markham mixes brand-new subdivisions like Cornell, Cathedraltown and Box Grove with the heritage character of Unionville, and homeowners here keep their properties sharp. Newer asphalt benefits from its first seal once it's cured to lock in the colour and protect it from day one, while Unionville's older driveways get the restorative crack-fill-and-coat treatment. Either way, a clean finish fits the neighbourhood.
