For most asphalt, every 2 to 3 years is the sweet spot.
Seal too often and you're wasting money and building up coats that can crack or peel. Wait too long and the asphalt starts oxidizing, drying out, and cracking, which costs more to fix than the sealcoat would have prevented.
A few things shift the timing:
High-traffic surfaces: Commercial parking lots, drive-thrus, and entrances wear faster. Plan on every 2 years, sometimes sooner on heavy-use areas.
Residential driveways: Lower traffic means longer life between coats. Every 3 years is normal, sometimes 4 if the first job was done right.
New asphalt: Wait at least 90 days before the first sealcoat. Too early and the sealer won't bond.
Climate: Freeze-thaw cycles, UV exposure, and salt all speed up wear. Ontario winters are hard on pavement, which is why staying on a regular schedule matters here more than in milder climates.
The look test: If the asphalt is fading from black to gray, you're due. If you can see aggregate poking through, you're overdue.
Sealcoat on schedule and your asphalt lasts significantly longer. Skip it and you'll be looking at full replacement years earlier than you should be.
