OSAZ also provides driveway paving, crack filling, and repairs throughout Oshawa and the surrounding Durham Region, as a local team based nearby in Ajax.
Asphalt sealing and sealcoating
Two coats of oil-based sealer, applied to protect your driveway from the road salt, sun exposure, and snowplow wear that are part of an Oshawa winter. Most driveways in this area hold up best with sealing every two to three years.
Driveway paving and new installation
Full-depth removal and replacement for Oshawa driveways, laneways, and commercial lots. Because the City caps paved front yard coverage at 50 percent, we factor lot layout into every quote so the finished driveway is compliant as well as durable.
Crack filling and asphalt repair
Hot-pour crack sealing before winter keeps water out of small cracks so they do not widen into potholes or larger structural repairs. We also handle spot patching for isolated damage.
Parking lot services (commercial)
Sealing, patching, and line painting for Oshawa plazas, offices, and multi-unit properties, scheduled around your operating hours.

OSAZ is a Durham Region asphalt team, based nearby in Ajax, with crews regularly working throughout Oshawa. We give every customer a written, no-obligation quote after an in-person assessment, and we stand behind the finished work with a satisfaction guarantee.

Where We Serve
Proudly serving homeowners and businesses throughout Oshawa, including Vanier, Central, O’Neill, Donevan, Windfields, and Taunton, as well as the surrounding Durham Region.
Two things worth knowing if you’re planning driveway work here specifically: the City of Oshawa limits paved coverage to 50 percent of your front yard, and curb-cut requests are only reviewed between April 1 and November 30 each year, so a widening project started late in the season may carry over to the following spring. We can walk through what that means for your timeline during your quote.

FAQs
How often should I seal my driveway in Oshawa?
Most driveways in this area benefit from sealing every two to three years, depending on sun exposure and how much salt or de-icer is used in winter. Sealing protects the surface rather than repairing damage, so it works best when applied before cracks or wear show up, not after.
Is there a limit on how much of my front yard I can pave in Oshawa?
Yes. City of Oshawa rules cap paved driveway coverage at 50 percent of the front yard area, to keep a minimum amount of landscaped space. This applies whether you are paving a new driveway or widening an existing one.
When can I apply for a curb cut in Oshawa?
Curb cut requests are reviewed between April 1 and November 30. Applications submitted outside that window are held until the following season, so if you’re planning a widening project, it’s worth starting the process early in the year.
How long does asphalt sealing take, and when can I use the driveway again?
Sealing itself typically takes a few hours for a standard residential driveway, but the surface needs time to cure. Plan to stay off it with vehicles for at least 24 hours, longer in cooler weather.
What's the difference between asphalt sealing and repaving?
Sealing is a protective maintenance step applied to asphalt that’s still structurally sound. It doesn’t fix cracks or potholes on its own. Repaving replaces the surface entirely and is needed once a driveway has significant cracking, potholes, or base failure. Most driveways only need repaving once every 15 to 20 years, with sealing in between to extend that lifespan.
What's the best time of year to seal a driveway in Oshawa?
Late spring through early fall is ideal, once temperatures consistently stay above about 10 degrees Celsius, so the sealant can cure properly. Sealing too late in the fall risks the product not curing before the first frost, which is why booking before the weather turns in October is a good idea.
