What Happens If You Delay?
Unsealed asphalt absorbs UV rays, water, and road salts — oxidizing and becoming brittle. Cracks that cost $200 to fill today will become potholes that cost $2,000 to repair in two years. Neglected driveways need full replacement within 10–15 years instead of 25–30.
Get a Quote NowHow We Work
Step 1: Crack Inspection
We inspect the entire surface for cracks, soft spots, and drainage issues — catching problems before they're sealed in.
Step 2: Crack Filling
We fill all cracks with hot rubberized crack filler — a critical step most budget operators skip or do poorly.
Step 3: Power Cleaning
The full surface is power washed to remove dirt, algae, and loose material. Sealer won't bond to a dirty surface.
Step 4: Edge Masking
We mask borders, garage doors, and grass edges to prevent overspray and ensure a clean, sharp line.
Step 5: Sealer Application
We apply commercial-grade coal tar or asphalt-based sealer by squeegee — not spray-and-pray. Two coats for maximum protection.
Step 6: Cure & Clear
We mark the driveway and advise a 24–48 hour cure time before vehicle traffic. Clean edges, sharp finish, done.

Frequently Asked Questions
Technical answers from people who do this work every day in Burlington and Oakville.
What exactly does sealcoating do to asphalt?
Asphalt is bound together by bitumen — a petroleum-based binder that oxidizes and breaks down when exposed to UV radiation, water, and road salts. Sealcoating applies a protective film over the surface that blocks UV penetration, repels water, and resists chemical absorption. It doesn't restore damaged asphalt — it preserves healthy asphalt. Think of it as sunscreen for your driveway.
What's the actual lifespan difference between sealed and unsealed asphalt?
Properly maintained asphalt (sealed every 3–5 years, cracks filled promptly) can last 25–35 years in Ontario's climate. Unsealed asphalt typically shows significant deterioration within 10–15 years and often requires full replacement within 20 years. The cost difference between a sealed driveway and a replacement is roughly 10:1 — maintenance is dramatically more economical.
How do you properly fill cracks before sealcoating?
Cracks must be cleaned of all debris and vegetation, then filled with hot rubberized crack filler (not cold-pour) that bonds to both walls of the crack and flexes with thermal expansion. Cracks wider than 3/4 inch typically require a patching compound before crack filler. Sealing over unfilled cracks traps moisture, accelerates oxidation below the surface, and provides zero structural benefit.
Why does new asphalt need to cure before sealing?
Fresh asphalt contains oils and solvents that must fully evaporate before the surface is sealed. Applying sealer to new asphalt (under 90 days old) traps these oils, preventing proper curing and resulting in a soft, unstable surface that marks easily. Best practice is to wait 6–12 months for the asphalt to fully cure and oxidize slightly before the first sealcoat application.
What's the difference between coal tar sealer and asphalt emulsion sealer?
Coal tar is a byproduct of steel manufacturing — highly resistant to fuel and oil penetration, very durable, but regulated in some jurisdictions due to environmental concerns. Asphalt emulsion is petroleum-based and more environmentally friendly, with good UV resistance but lower chemical resistance. For residential driveways in Burlington, high-quality asphalt emulsion is the standard professional choice.
