Driveway Sealing Whitby Homeowners Choose to Protect Their Driveway
Driveway sealing Whitby residents and businesses count on shields asphalt from road salt, sun exposure, and the freeze-thaw swings that are part of a Durham Region winter. OSAZ also handles driveway paving, crack filling, and repairs across Whitby, as a local team based nearby in Ajax.
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 won't fix existing cracks or potholes, so we address those first if needed, then apply the sealer for lasting protection.
Driveway paving and new installation
Full-depth removal and replacement for Whitby 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 Whitby plazas, offices, and multi-unit properties, scheduled around your operating hours to minimize disruption.
Why Whitby Homeowners and Businesses Trust OSAZ
OSAZ is a Durham Region asphalt team based nearby in Ajax, with crews regularly working in Whitby. Every quote follows an in-person assessment, comes with no obligation, and reflects the real condition and size of your driveway or lot rather than a flat regional rate. We stand behind finished work with a satisfaction guarantee, and because Whitby’s boulevard and edging rules differ in specific ways from neighbouring towns, we factor what applies to your property into the plan before work starts.

Where We Serve
Proudly serving homeowners and businesses throughout Whitby, including Brooklin, Port Whitby, Williamsburg, Downtown Whitby, Rolling Acres, and Whitby Shores, as well as the surrounding Durham Region.
Two things worth knowing if you’re planning driveway work here specifically: the Town of Whitby’s Property and Boulevard Maintenance By-law requires driveway edging, hedges, or fencing to stay at least 300mm (about 12 inches) from a municipal sidewalk, and any widening that extends onto the Town-owned boulevard needs a curb-cut permit first. We can walk through what that means for your property during your quote.

FAQs
How do I know if my driveway needs sealing?
Common signs include fading or graying asphalt, a rough or pitted surface, water that no longer beads on the surface, and small surface cracks starting to appear. Catching these early means sealing can still protect the surface, rather than needing repairs first.
Can I seal my own driveway, or is it better to hire a professional?
A small, newer driveway in good condition can sometimes be sealed as a DIY project. Larger driveways, older asphalt, or surfaces with existing cracks tend to get better, longer-lasting results from a professional, since contractors have access to commercial-grade sealer and equipment that isn’t available at most hardware stores.
How many coats of sealer will my driveway need?
Two coats is the standard most professional contractors recommend for residential driveways, since a single coat protects the surface but wears faster and needs more frequent resealing. Two coats cost a bit more upfront but typically extend the time between resealing.
Do I need a permit to widen my driveway or add edging in Whitby?
Widening a driveway that extends onto the Town-owned boulevard requires a curb-cut permit from the Town of Whitby. Separately, any edging, hedges, or fencing you add along the driveway need to stay at least 300mm from a municipal sidewalk under the Town’s Boulevard Maintenance By-law.
What's the difference between professional-grade sealer and store-bought DIY sealer?
Professional contractors typically use commercial-grade sealer purchased in bulk, which tends to be more durable and consistent than the smaller retail buckets available at most hardware stores. The tradeoff is access and cost per job: DIY sealer is easier to buy in small quantities, while professional-grade product is usually reserved for contractors buying in volume.
