Penetrating sealer for paver driveways, walkways and patios. Deepens colour, locks joints, slows weed growth.

Why Driveways Fail Here

Southern Ontario pavement doesn't wear out so much as it gets taken apart. The mechanism is freeze-thaw: water finds its way into the surface, freezes, expands, and levers the aggregate loose. Then it thaws and does it again. Repeat that through a Guelph winter and a hairline crack becomes a pothole.

Sealer is a wear coat. It slows the oxidation that turns asphalt grey and brittle, and it keeps water out of the top layer. What it is not is a structural repair — it won't fix a failed base, and it won't close a crack that hasn't been filled. Anyone selling it as a cure-all is selling you something.

Which is also why the timing matters more than most people expect. Sealer cures by evaporation, so it needs surface temperature and a dry window on both sides of the job. Get that wrong and you've paid for a coat that won't bond.

Straight answer: if your asphalt is still black and tight, you probably don't need us this year. We'd rather tell you that than sell you a coat you don't need and have you find out in two years when it peels.

Common Questions

When should a driveway be sealed in Ontario?

Sealer needs surface temperature above roughly 10°C and a dry window of about 24 hours after it goes down. That puts the season between late spring and early autumn. A warm April afternoon can still be too cold if the ground hasn't warmed.

My driveway was paved this year. Can it be sealed?

Usually not yet. Fresh asphalt is commonly given six to twelve months to cure before its first seal. Sealing too early can trap the oils still leaving the surface. If it was paved this season, next year is normally the right answer.

How often does it actually need doing?

Judge the driveway, not the calendar. Grey asphalt where you can pick out individual stones has oxidised and is due. Still-black, tight asphalt isn't. Over-sealing is a real failure mode — too many coats build up and peel off in sheets.

Do cracks need filling first?

Yes, and it's the part that decides whether the job lasts. Sealer poured over an open crack bridges it and splits along the same line by spring. Hot-pour filler goes in first.

What does it cost?

It depends on square footage, condition, how much crack filling is needed and whether it's asphalt or interlock — so we quote on site rather than guessing at a number here. Ask any contractor what's included and what's extra before you agree.
