Driveway Sealing Ajax Homeowners Trust to Protect Their Investment
Driveway sealing Ajax homeowners and businesses count on protects asphalt from road salt, sun exposure, and the freeze-thaw swings that are part of a Durham Region winter. OSAZ is a local, Ajax-based team, and we also handle driveway paving, crack filling, and repairs for properties across town.
Asphalt sealing and sealcoating
A protective, oil-based sealer applied in two coats, the standard most contractors recommend for driveways that see regular vehicle traffic and Ontario winters. Sealing restores a rich, dark finish and protects the surface, but it won't fix existing cracks or potholes on its own, so we address those first if needed.
Driveway paving and new installation
Full-depth removal and replacement for Ajax driveways and commercial lots, with proper base preparation so the new surface holds up rather than settling or cracking early.
Crack filling and asphalt repair
Hot-pour crack sealing before winter keeps moisture out of small cracks so freeze-thaw cycles don't turn them into potholes. We also handle spot repairs for isolated surface damage.
Parking lot services (commercial)
Sealing, patching, and line painting for Ajax plazas, offices, and multi-unit properties, scheduled around your operating hours to minimize disruption.

Where We Serve
Proudly serving homes and businesses throughout Ajax, including Pickering Village, Riverside, Westney Heights, Audley, and Duffins Bay, as well as Whitby, Pickering, Oshawa, and the surrounding Durham Region.
If you’re planning to widen your driveway, the Town of Ajax’s Zoning By-law #95-2003 requires a minimum 0.60 metre clearance from the widened edge to the property line, and circular or secondary driveways aren’t permitted. We can walk through what that means for your property during your quote.

FAQs
How soon can I seal a freshly paved driveway in Ajax?
New asphalt needs time to cure before it can be sealed properly, usually 6 to 12 months, with 90 days as an absolute minimum. Sealing too early traps the oils that keep the asphalt flexible, which can lead to a softer surface that’s more prone to damage. If you’ve just had a driveway paved, we’ll let you know when it’s ready for its first seal.
Will sealing change the look of my driveway?
Sealing restores the deep black finish that new asphalt has and helps prevent the dull, grey fading that happens as UV rays break down the surface over time. It’s more accurate to say sealing maintains and refreshes the original look rather than changing it to something different.
What happens if I don't seal my driveway?
Unsealed asphalt is more exposed to water, road salt, and UV damage, which speeds up fading, cracking, and eventually potholes. Sealing isn’t required to keep a driveway functional, but skipping it usually means more frequent repairs and a shorter overall lifespan for the pavement.
Do I need a permit to widen my driveway in Ajax, and are there design rules to know about?
Yes. Widening requires approval under Town of Ajax Zoning By-law #95-2003, which sets a minimum 0.60 metre clearance from the widened driveway edge to the property line. The by-law also doesn’t permit circular or secondary driveways, so it’s worth checking your plan against these rules before work begins.
How often should I reseal my driveway in Ajax?
Most Ajax driveways hold up well with resealing every two to three years, though sun exposure, traffic, and how much salt or de-icer gets used each winter can shift that timeline in either direction. Watching for fading colour or a rough surface is a more reliable signal than going strictly by the calendar.
