Introduction: Why Ontario Driveways Don’t Last Forever
If you’ve ever wondered why your driveway looked great when it was first installed but started cracking, fading, or sinking within a few years, the answer is simple: Ontario weather. Our climate is one of the harshest in North America when it comes to driveways.
The combination of sub-zero winters, scorching summers, heavy snow removal, and road salt creates the perfect storm for asphalt, concrete, and interlock surfaces. Without proper maintenance and sealing, even the highest-quality driveway can deteriorate prematurely.
At No Limit Sealing, we’ve seen the same problems repeat across Vaughan, Richmond Hill, Markham, Aurora, Newmarket and Toronto — and we know exactly how to fix and prevent them.
The Big 4 Weather Hazards for Driveways in Ontario
1. Freeze-Thaw Cycles
- The problem: Water seeps into small cracks in your driveway. When the temperature drops, that water freezes, expands, and forces the crack to widen.
- The result: Cracks that started hairline-wide in October are potholes by March.
- Who’s most affected: Asphalt driveways in areas like Aurora and Newmarket, where snow accumulation is high.
👉 Solution: Sealing fills surface pores, reducing water penetration and preventing freeze-thaw expansion.
2. Salt & De-Icing Chemicals
- The problem: Salt is essential for safe winter driving, but it eats away at both asphalt and interlock. On asphalt, it accelerates binder breakdown; on interlock, it leaves a white residue and weakens the stone.
- The result: Driveways look faded, stained, and structurally weaker.
- Who’s most affected: Homeowners in Richmond Hill, Markham and Vaughan, where city plows spread salt heavily.
👉 Solution: Sealer acts as a protective shield, stopping salt and chemicals from reaching the surface.
3. Heavy Snow & Ice
- The problem: Snowplows, shovels, and ice buildup put stress on the driveway surface. Scraping with metal shovels or plow blades can chip interlock edges and damage asphalt.
- The result: Broken pavers, surface gouges, and uneven driveways.
- Who’s most affected: Large driveways in suburban areas like Richmond Hill, Aurora and Newmarket where homeowners rely on snow removal services.
👉 Solution: Sealed surfaces resist abrasion, making them less likely to chip under plow blades.
4. Sun & UV Exposure
- The problem: In the summer, UV rays break down asphalt binders, causing fading and brittleness. Interlock stones lose their rich colour, looking dull and aged.
- The result: Asphalt turns grey, interlock loses vibrancy, and both become more vulnerable to water penetration.
- Who’s most affected: Exposed driveways with little shade in Toronto and the GTA.
👉 Solution: Sealers with UV protection restore colour and prevent sun damage.
How Sealing Protects Driveways Year-Round
Sealing isn’t just about appearance — it’s about durability. A professionally sealed driveway:
- Prevents water penetration → Reduces freeze-thaw cracking.
- Blocks salt & chemicals → Protects against winter damage.
- Resists UV fading → Keeps asphalt black and interlock vibrant.
- Locks in joint sand → Stops shifting and weed growth in interlock.
- Boosts curb appeal → Fresh, restored look adds value to your home.
In fact, a sealing job done every 2–3 years can double the lifespan of your driveway compared to one that’s left unprotected.
What Happens If You Don’t Seal?
- Asphalt cracks turn into costly repaving jobs ($6,000–$10,000+).
- Interlock becomes uneven and requires full re-levelling.
- Colours fade permanently, reducing curb appeal.
- Weeds and moss take over between stones.
Homeowners across Vaughan, Richmond Hill, and Aurora who put off sealing often call us later — but by then, repairs are far more expensive. Preventive maintenance is always cheaper than replacement.
FAQs About Ontario Weather & Driveways
Q: How often should I seal my driveway in Ontario?
A: Every 2–3 years for asphalt, and every 3–4 years for interlock, depending on exposure.
Q: Does sealing really stop salt damage?
A: Yes. Sealer creates a barrier that prevents salt and de-icers from penetrating the surface.
Q: When’s the best time to seal in the GTA?
A: Late spring through early fall, when the weather is warm and dry for at least 24 hours.
Q: Can I seal my driveway in winter?
A: No. Cold temperatures and moisture prevent proper curing. Sealing is a warm-weather job.
