How much does seal coating cost in Billings, MT, and how often should you do it?
Published 2026 cost guides put professional driveway sealing at $1 to $2 per square foot. That is about $275 to $875 for a typical home driveway. A pavement sealer maker puts typical sealcoating at 10 to 30 cents per square foot on larger areas. Most pavement gets resealed every two to three years.
Those are national market ranges, not our prices. A real number needs a look at the pavement, because prep decides most of the bill. We handle asphalt seal coating on driveways and parking lots around Billings, Laurel, Lockwood and the Yellowstone Valley.
What does seal coating cost per square foot?
Two published per foot figures exist, and they sit far apart. A 2026 consumer cost guide puts professional driveway sealing at $1 to $2 per square foot with labor. SealMaster, a pavement sealer maker, puts typical sealcoating at 10 cents to 30 cents a square foot.
| What is priced | Published 2026 range per sq ft | Source |
|---|---|---|
| Sealer material alone | $0.10 to $0.50 | Consumer guide |
| Labor to clean and apply | $0.90 to $1.50 | Consumer guide |
| Home driveway, applied | $1.00 to $2.00 | Consumer guide |
| Sealcoating in general | $0.10 to $0.30 | Sealer manufacturer |
Job size explains the gap. Small jobs carry a minimum, because moving the tank, the blower and the crew costs about the same for a 400 square foot drive as for a 40,000 square foot lot. One guide lists a $110 minimum against a $600 national average.
What do common driveway and lot sizes cost?
Measure the pavement and multiply. A 500 square foot single drive runs about $500 to $1,000 at published residential rates. A 1,000 square foot two-car drive runs about $1,000 to $2,000. A 10,000 square foot business lot prices nearer the industry figure, roughly $1,000 to $3,000.
| Surface | Square feet | Published range | Rate used |
|---|---|---|---|
| Small drive, 20 by 25 | 500 | $500 to $1,000 | $1 to $2 per sq ft |
| Wide drive, 25 by 40 | 1,000 | $1,000 to $2,000 | $1 to $2 per sq ft |
| Small business lot | 10,000 | $1,000 to $3,000 | 10 to 30 cents |
The fixed cost spreads across more pavement, so big areas price near the low end. Ten thousand square feet is a small lot, and at published rates the sealing still lands in four figures. Striping gets quoted with it, since fresh lines go back over the new coat. Big lots get phased in sections, which is normal on commercial paving and lot maintenance. If a drive is too far gone to seal, compare it against what new asphalt costs here.
How often should a driveway or parking lot be sealed?
Every two to three years covers most pavement. SealMaster recommends sealcoating every 3 years for adequate protection. A national cost guide widens that to 2 to 10 years depending on the sealer and the climate. Billings sits at the short end, and the winter is why.
| Use | Published reseal interval | What wears the coat here |
|---|---|---|
| Home driveway | Every 2 to 3 years | Sun, plow blades, about 81 freeze-thaw cycles a year |
| Small business lot | Every 2 to 3 years | Turning traffic, fuel and oil drips at stalls |
| Busy commercial lot | Every 2 to 3 years, third coat on drive lanes | High daily volume |
SealMaster names six factors: sealer quality, mix design, number of coats, amount applied, daily traffic and geography. Harsh winter regions see faster sealcoat wear, from moisture, freeze-thaw cycles and snow plowing.
Billings has all three. About 81 freeze-thaw cycles a year work water in and out of the surface, and 57.4 inches of average snow puts steel blades on the coating each winter.
When can seal coat go down in Montana?
Pavement at 50 degrees or warmer, air at 50 and rising, no freeze inside 24 hours and no rain inside 8 hours. Those are the Colorado Asphalt Pavement Association’s conditions. A sealer maker’s spec sheet matches them: surface and air at a minimum of 50 degrees, with no drop below 50 for 24 hours after.
Montana DOT stops plant mix paving on November 1. Sealer needs warm pavement and a warm night behind it, so the sealing window shuts weeks ahead of the paving one.
New pavement is its own case. The spec sheet calls for new asphalt to cure a minimum of four weeks under ideal 70 degree weather before the first coat. Consumer guides commonly say 3 to 6 months. A drive paved here in September usually waits for next season.
What has to happen before the sealer goes on?
Cleaning, crack filling and patching, then the coating. Full depth patches want 30 to 90 days to cure before sealing. Cracks wider than a quarter inch get hot rubberized crack sealant first. Sealer is a coating over pavement that is already sound, so repairs are a separate line on the bid.
The manufacturer’s sequence runs in order: clean, treat oil spots with primer, patch potholes, fill cracks, apply at least two coats, then stripe.
Coverage tells you when a bid is thin. SealMaster’s coal tar ready mix spec puts one gallon at roughly 80 to 95 square feet per coat. Two coats on a 1,000 square foot drive is about 21 to 25 gallons of mixed material.
Prep is where hot rubberized crack sealing and asphalt repair and patching come in. It decides whether the coat is still there in three years.
Is seal coating worth it?
On sound pavement, by the industry’s own math, yes. SealMaster says a scheduled program of crack filling and sealcoating will more than double the life of asphalt pavement. It puts sealing at less than one tenth the cost of repaving with hot mix.
A few cracks and a gray, dry surface is a sealing job. Alligator cracking across a wide area means the base under the mat has gone. Our guide to patching versus repaving covers how to read your own surface.
How do you get a real number?
Measure the pavement and note anything soft, broken or stained. Then ask for a written quote that names the number of coats, the sealer and the prep included. A per foot average cannot see the oil at the garage door.

FAQ
How much does it cost to seal coat a 1,000 square foot driveway? At the $1 to $2 per square foot that 2026 guides publish for professional driveway sealing, a 1,000 square foot drive lands around $1,000 to $2,000. Larger areas price closer to the industry figure of 10 to 30 cents per square foot.
Is seal coating asphalt worth it? The sealer industry says a scheduled program of crack filling and sealcoating more than doubles the life of asphalt pavement, at less than one tenth the cost of an overlay. That holds on sound pavement. Failed base means repair comes first.
How long will seal coating last? Two to three years is the common published recommendation, and one guide gives 2 to 10 years depending on the sealer and the climate. Billings sits at the short end, with about 81 freeze-thaw cycles a year and 57.4 inches of snow.
What month should you seal a driveway in Montana? The window runs from late spring into early fall. Sealer makers require pavement and air at 50 degrees or warmer, with no drop below 50 in the 24 hours after the coat goes down. Once nights fall under that line, sealing waits for spring.
What happens if it rains right after sealing? Rain on uncured sealer washes it off the pavement and into the gutter. Manufacturers say not to apply if rain is coming inside the same 24 hour period, and the asphalt association rule allows no rain for at least 8 hours.
When should you seal a new asphalt driveway? Not right away. One sealer maker’s spec sheet calls for new asphalt to cure a minimum of four weeks under ideal 70 degree weather first. Consumer guides commonly say 3 to 6 months. A drive paved here in fall waits for spring.
Why do some people say sealing is pointless? Usually because they watched a coat fail. Sealer put over dirt, over open cracks or thinned too far peels inside a season. Applied at 50 degrees and rising, in two coats at roughly 80 square feet per gallon, it holds.
