“How much does it cost to seal a driveway?” is the first thing every GTA homeowner asks — and the honest answer is: it depends on a few things you can actually understand. Here’s what drives the price, what a proper job should include, and how to make sure you’re comparing apples to apples.
What actually affects the price
- Size. The biggest factor. A single-car driveway costs far less than a wide double or a long estate laneway. Most sealers price by square footage.
- Condition. A clean, well-kept driveway seals quickly. One that needs heavy crack-filling, weed removal or oil-stain treatment takes more prep — and prep is where quality jobs are won or lost.
- Type of sealer. Real tar-based (oil) sealer costs more than the watered-down spray some operators use — and lasts far longer.
- Edging & detail. Hand-edged borders around grass, curbs and walkways take skill and time. It’s the difference between a crisp finish and overspray on your lawn.
What a proper job includes
Before you compare any two quotes, make sure they both include the same work. A complete driveway sealing job should cover:
- Thorough cleaning and blow-down before any sealer goes down
- Crack-filling on every visible crack — this should never be a surprise upcharge
- High-grade tar-based oil sealer, not water-based
- Hand-edged borders and full masking of your grass, curbs and garage
- An even, jet-black coat applied in one consistent pass
- Complete cleanup and flag-taping so the seal cures undisturbed
Beware the lowball quote
If one quote is dramatically cheaper, it’s almost always because something’s missing — watered-down sealer, no crack-filling, no edging, or a rushed single thin coat that fades in a season. A driveway sealed properly once every 2–3 years is an investment; a cheap spray-and-go job is money you’ll spend again next year.
