How Much Does Driveway Sealing Cost in London, Ontario?

Driveways · 5 min read

If your asphalt driveway is fading to grey, showing fine cracks or just looking tired, sealing is one of the cheapest ways to protect it and sharpen your curb appeal. But what should you actually expect to pay in London in 2025? Here's a straightforward breakdown — no lowball teaser pricing, just realistic ranges and what moves the number.

Typical Price Ranges

For a standard residential asphalt driveway in the London area, professional sealing generally lands somewhere in the low-to-mid hundreds of dollars. A small single-car driveway sits at the lower end; a wide double or a long rural drive runs higher. The exact figure depends on square footage, the condition of the surface, how much crack filling is needed, and the quality of sealer used. The most reliable way to know your price is a free on-site quote — measuring and eyeballing the cracks in person beats any online calculator.

What Drives the Cost

Size is the obvious one — sealer is priced largely by area. Condition matters just as much: a driveway with significant cracking needs crack filling first, which adds labour and materials. Prep is non-negotiable for a result that lasts; a proper job includes cleaning, removing weeds from cracks, and letting the surface dry fully before sealing. Finally, sealer quality varies. A bargain coat that washes off in a season isn't a deal. We use durable commercial-grade sealer because resealing every single year is a false economy.

How Often Should You Reseal?

For most London driveways, every two to three years is the sweet spot. Seal too often and you build up brittle layers; wait too long and water, UV and our brutal freeze-thaw winters get into the asphalt and cause the cracking that leads to expensive repaving. Think of sealing as cheap insurance against a very expensive replacement.

Is It Worth It?

Repaving an asphalt driveway costs many times more than sealing it. A modest sealing budget every couple of years protects that far larger investment, keeps water out of the base layer, and makes the whole property look cared-for. For homes going on the market, a freshly sealed driveway is one of the highest-return cosmetic touches there is.

Bundle and Save

Many of our clients book driveway sealing alongside pressure washing of their walkways and siding, since we're already on site with the gear — the whole front of the house gets refreshed in one visit. You can see our full approach on the driveway sealing page.
