Driveway sealing in Ottawa costs about $0.35 to $0.75 per square foot in 2026, which works out to roughly $180 to $450 for a typical two-car asphalt driveway of 500–600 square feet. Small single-car driveways often come in at $150–$250, while long suburban or rural driveways of 1,000+ square feet commonly run $400–$800. Crack filling is usually priced separately at $1.50–$4 per linear foot or bundled as a $75–$200 add-on. Interlock and paver sealing is a different job entirely, costing $1.50–$3.50 per square foot because it requires cleaning, re-sanding joints, and a penetrating sealer. Ottawa...
Sealing is priced by square footage, and most Ottawa contractors work from a per-square-foot rate with a minimum charge. A compact single-car driveway of about 300–400 sq ft usually costs $150–$280. The most common suburban size — a two-car driveway around 500–600 sq ft in Barrhaven, Orléans, or Kanata — typically runs $180–$450 depending on condition and sealer grade. Wide double driveways of 800–1,000 sq ft land near $350–$650, and long rural laneways in Greely, Manotick, or Carp can exceed $8...
Hot rubberized crack filling costs about $1.50–$4 per linear foot in Ottawa, or $75–$200 bundled with a sealing job. Skipping it is false economy — sealer alone bridges hairline cracks but does nothing for gaps wider than about 6 mm.
These are two different services with very different price tags, and homeowners often confuse them when calling for quotes. Asphalt sealcoating applies a surface film that blocks UV, oxygen, water, and salt from degrading the bitumen binder — it is fast, inexpensive, and typically done in a single afternoon. Interlock and concrete-paver sealing costs considerably more, roughly $1.50–$3.50 per square foot in Ottawa, because the process involves pressure washing, removing weeds and moss from joint...
Timing matters more than most homeowners realize. A brand-new asphalt driveway should cure for at least 6 to 12 months before its first seal; sealing too early traps oils in the surface and can leave a soft, scuffing finish. After that, resealing every two to three years is the sweet spot in Ottawa — annual sealing is a common upsell that builds up brittle layers that eventually flake. Sealing season here runs from late May through early October, and the job needs surface temperatures above abou...
Grey, faded colour instead of dark black; visible loose aggregate when you sweep; water soaking in rather than beading; and new hairline cracks appearing. If it has been three or more winters, it is due.
Every spring, Ottawa neighbourhoods see door-to-door crews offering to seal your driveway for $99 because they "have leftover material from a job down the street." This is one of the most persistent home-services scams in the region, and the Ontario Ministry of Public and Business Service Delivery regularly warns about it. The tells are consistent: unmarked trucks, no written contract, cash-only pricing, pressure to decide immediately, and no company name you can look up. What you typically get ...
DIY sealing is genuinely viable on smaller driveways. Buckets of driveway sealer run about $40–$70 each at Ottawa big-box stores, and a 500 sq ft driveway needs roughly three to four buckets for a proper coat, so material alone is $150–$280 — plus a squeegee applicator, crack filler, and a degreaser for oil spots. That means DIY often saves only $50–$150 over a professional job on a typical two-car driveway, and it costs you a full day of scraping, edging, and squeegeeing. Professionals also bri...
In 2026, driveway sealing in Ottawa costs about $0.35–$0.75 per square foot, or roughly $180–$450 for a typical 500–600 sq ft two-car asphalt driveway. Small driveways often hit a $150–$200 minimum charge, and large or rural laneways can exceed $800.
Every two to three years is ideal for Ottawa's freeze-thaw and road-salt conditions. Sealing every single year builds up brittle layers that flake, and waiting more than four years lets water penetrate the asphalt binder and accelerate cracking.
Late May through early October. You need surface temperatures above roughly 10°C, no rain for 24 hours after application, and 24–48 hours before driving on it. Late-fall sealing often fails to cure properly because of cool nights and heavy dew.
Interlock and paver sealing costs about $1.50–$3.50 per square foot in Ottawa, so a 500 sq ft interlock driveway typically runs $750–$1,750. The price includes pressure washing, weed and moss removal, re-sanding joints with polymeric sand, and applying the sealer.
Yes, on structurally sound asphalt. Sealing blocks water, salt, and UV from degrading the binder, and in Ottawa's climate that can add years to the driveway's life for a few hundred dollars. It is not worth it if the driveway already has alligator cracking, potholes, or base settlement — those need resurfacing or replacement.
