How this calculator works
Sealing is asphalt’s oil change — cheap, periodic, and the difference between a 15-year and a 25-year driveway. It’s also the rare yard job where DIY and pro are both sensible answers.
How the pricing works
Pros price by the square foot, with the condition doing most of the variation: a clean surface just gets sealcoat, while a cracked one needs hot or cold crack filler first — prep that can double the rate. Small driveways collide with the job minimum (crews can’t roll a rig out for $60), which the calculator models; it’s why neighbors batching their driveways together is a genuine money move.
The DIY math
Sealer comes in 5-gallon pails covering roughly 250–400 square feet each, and the calculator counts pails for your size. With a squeegee, driveway brush, and a dry 50°F+ weekend, most owners can match a pro finish on a flat drive. Budget honesty: your first crack-filling session is slower and stickier than the videos suggest.
What sealing won’t fix
Sealer is sunscreen, not surgery. Alligator cracking, sunken wheel ruts, and crumbling edges are base problems — sealing over them buys appearance, not time. If that’s where your driveway is, run the numbers on an overlay or replacement instead, and keep sealing for the new surface’s third birthday.
2026 driveway sealcoating cost per square foot
Professionally applied. Crews carry a practical job minimum around $150, which is why tiny driveways cost more per square foot than big ones.

Frequently asked questions
How much does driveway sealing cost in 2026?
Professional sealcoating runs about $0.20–$0.65 per square foot, or $0.35–$1.00 with crack filling first — so a typical two-car driveway lands in the $150–$400 range. DIY materials for the same job are often under $100 in sealer pails.
How often should asphalt be sealed?
Every 3–5 years is the standard cadence — and not within the first year of new asphalt, which needs to cure first. Sealing more often than every couple of years just builds up product; the surface will tell you when gray, dry, and faded means it's time.
Is sealing a driveway worth doing myself?
It's one of the best-value DIY jobs on the property — a 5-gallon pail covers roughly 250–400 square feet, and the work is squeegee-pushing on a warm day. The calculator shows the pail count. The trade-offs are crack prep (the tedious part pros do faster) and a 24–48 hour cure you'll be staring at either way.
Does sealing actually extend asphalt life?
Yes, within reason — sealer blocks UV oxidation and water intrusion, the two things that age asphalt. Sealed every few years, a driveway routinely makes 20–25 years; never sealed, the surface dries, cracks, and unravels years sooner. What sealing can't do is fix a failing base.
Why was my quote higher than this range?
Usually crack or pothole repair — filling bad cracking is real prep labor, and patching potholes is a separate line item. Steep slopes, hand-edging, and heavily oxidized surfaces that drink extra sealer also add. A quote should itemize prep separately from the sealcoat itself.
