How Often Should You Seal Your Driveway?
May 8, 2026
Asphalt driveways should be sealcoated every 2-3 years. Concrete driveways should be sealed every 2-5 years. This is one of the highest-ROI maintenance tasks for your home's exterior... a $100-$300 sealcoat application can add 5-10 years to an asphalt driveway's life and prevent thousands in repair costs.
Asphalt Driveways: Every 2-3 Years
Asphalt is a petroleum-based product that oxidizes from UV exposure. As the oil binder dries out, the asphalt becomes brittle, turns gray, and develops cracks. Sealcoating replaces that protective layer.
A fresh sealcoat: blocks UV rays (the primary cause of asphalt deterioration), repels water (water in cracks causes freeze-thaw damage), fills minor surface imperfections, and restores the dark black appearance.
Don't sealcoat too often. More than every 2 years builds up too many layers that can peel and flake. And don't sealcoat a brand new driveway... wait 6-12 months for the asphalt to fully cure.
DIY cost: $30-$60 for sealant (one 5-gallon pail covers 300-400 sq ft) plus a squeegee applicator. Professional cost: $100-$300 for a typical two-car driveway.
Concrete Driveways: Every 2-5 Years
Concrete sealers work differently than asphalt sealcoat. They penetrate into the concrete (penetrating sealers) or form a film on top (topical sealers) to prevent water absorption, salt damage, and staining.
Penetrating silane/siloxane sealers are best for driveways... they don't change the appearance, they last 5-10 years, and they work by repelling water from within the concrete rather than sitting on top. Topical sealers (acrylic) add a wet-look sheen but wear off in 1-3 years and can become slippery when wet.
In freeze-thaw climates, sealing concrete is essential. Water absorption + freezing = spalling (the surface flakes off). A sealed concrete driveway in Minnesota lasts twice as long as an unsealed one.
DIY cost: $40-$60 for a gallon of penetrating sealer (covers 200-400 sq ft). Professional cost: $200-$500 for a typical driveway.
How to Tell It's Time to Reseal
Asphalt: the surface has faded from black to gray. Water soaks in instead of beading on the surface. Small cracks are appearing.
Concrete: sprinkle water on the surface. If it soaks in and darkens the concrete within 30 seconds, the sealer has worn off and the concrete is absorbing water. If it beads up, the sealer is still working.
Both: if it's been more than 3 years since the last application and you can't remember when you last sealed it, it's probably time.
DIY Application Tips
Best conditions: dry surface, temperature between 50-85°F, no rain expected for 24-48 hours. Early morning or evening application avoids the sealant drying too fast in direct sun.
For asphalt: fill any cracks with crack filler first and let it cure. Clean the surface with a pressure washer or stiff broom. Apply sealcoat with a squeegee in thin, even coats. Two thin coats are better than one thick coat. Let the first coat dry 4-8 hours before applying the second.
For concrete: clean the surface thoroughly (pressure wash, let dry 24 hours). Apply penetrating sealer with a pump sprayer or roller. One coat is usually sufficient for penetrating sealers. Don't over-apply... puddling means you've applied too much.
Stay off the driveway for 24-48 hours after application.
