Professional sealcoating of an asphalt driveway runs about $355 to $800 for a typical 400 square foot driveway. Fixr puts the national average at $468, in a range of $355 to $600, and HomeGuide lists $400 to $800, or $1 to $2 per square foot. Some contractor-published prices run lower, because many crews work to a minimum charge of about $150 to $200. The sealer itself is the small part of the bill, at about $0.13 to $0.26 per square foot for two coats. Rates of $0.15 to $0.30 per square foot are commercial parking lot rates and do not describe a driveway.
How much does asphalt driveway sealcoating cost?
Professional sealcoating runs about $355 to $800 for a typical 400 square foot driveway. Fixr puts the national average at $468, within a range of $355 to $600, for a flat 20 by 20 foot driveway in fair condition. HomeGuide lists $400 to $800 for 400 square feet, or $1 to $2 per square foot including labor. Both were checked in October 2026. These are consumer cost guides and not government data, so treat them as planning numbers and get three local quotes before you commit.
Some contractors and quote platforms publish lower figures than those two guides. The table below is our reconciliation of those lower sources, and for the same 400 square foot driveway it gives $175 to $325, about half the national guides. Both sets are published in good faith. Budget from the national guides, and treat a quote in the lower range as a good one.
| Driveway | Area | Contractor-published quote range | Works out to |
|---|---|---|---|
| 1 car, 10 × 20 ft | 200 sq ft | $150 to $250 | $0.75 to $1.25 / sq ft |
| 2 car, 20 × 20 ft | 400 sq ft | $175 to $325 | $0.44 to $0.81 / sq ft |
| 1 car long, 12 × 40 ft | 480 sq ft | $175 to $350 | $0.36 to $0.73 / sq ft |
| 2 car long, 20 × 40 ft | 800 sq ft | $200 to $450 | $0.25 to $0.56 / sq ft |
| Wide, 24 × 50 ft | 1,200 sq ft | $275 to $600 | $0.23 to $0.50 / sq ft |
| Large, 30 × 60 ft | 1,800 sq ft | $400 to $850 | $0.22 to $0.47 / sq ft |
| Very large, 40 × 80 ft | 3,200 sq ft | $650 to $1,500 | $0.20 to $0.47 / sq ft |
Read the right-hand column before anything else. The cost per square foot falls by more than half across that table without the work changing at all. The sealer, the crew and the method are the same at 200 square feet as at 3,200. Only the arithmetic moves, because a fixed cost is being divided by a bigger number.
Why every published sealcoating price per square foot is different
Search this question and you will be told sealcoating costs $0.08 per square foot, and $1.50 per square foot, and several things in between. Both extremes are quoted honestly by people who know the trade. They disagree because they are describing different jobs. The lowest figures, around $0.15 to $0.30 per square foot, are commercial parking lot rates: tens of thousands of square feet sprayed in one visit. A driveway is a small job with the same fixed costs, so its price per square foot is far higher.
What one 600 sq ft driveway costs, by published source
About four times between the cheapest and the dearest account of the same driveway. Three things explain nearly all of it.
- Coat count. The Colorado Asphalt Pavement Association specifies two coats over the whole surface, with a third only in high-traffic areas. A one-coat job uses half the material and takes most of a day off the schedule. It is a legitimate cheaper product, not a scam, but it is not the same product.
- Who is being surveyed. Trade sources such as PavemanPro publish the rate a contractor charges for area. Aggregators publish what homeowners reported paying for a whole job, and homeowners overwhelmingly have small driveways where the minimum charge, not the area, sets the price.
- How old the figure is. Some cost pages that rank for this search have not been updated in years, and sealer prices have moved since. Check the date on any figure before you budget from it, including the dates given for each source on this page.
None of those are bad-faith numbers. They are simply not comparable, and averaging them produces a figure that describes no real driveway.
The minimum charge, not the square footage, sets the price on most driveways
Many residential sealcoating jobs are priced by the visit. Yelp, working from 286 real contractor quotes, puts the minimum job charge at $150 to $200, and V&F Paving publishes a flat $200 minimum per address. On a driveway small enough to be sealed in an afternoon, that minimum can be the entire quote.
The reason is the same one that makes a single pothole repair cost more per square foot than paving a whole driveway. A crew has to load a tank, drive to your house, mask the garage apron and the edges, and lose the truck for half a day. That cost exists whether you have 200 square feet or 900. Our guide to pothole repair cost works the same arithmetic through in more detail.
The effect fades as the driveway gets larger. In the contractor-published table above, the price works out to $0.44 to $1.25 per square foot on driveways of 400 square feet or less and $0.20 to $0.56 on driveways of 800 square feet or more. Below about 800 square feet you are mostly buying a visit. Above it, comparing quotes per square foot starts to mean something.
The mistake this causes
Someone reads a guide's $1 to $2 per square foot, multiplies it by their 2,000 sq ft driveway, and braces for $2,000 to $4,000. Contractor-published figures for a driveway that size run $400 to $800. The per-square-foot rate was derived from small driveways, where a fixed visit cost is divided by a small area. Never scale a small-driveway rate up to a large driveway.
What the sealer in that quote actually costs
The sealer itself is $0.13 to $0.26 per square foot for two coats. On a typical 600 sq ft driveway that is $78 to $156 of material, whatever the quote says. Everything else is the visit, the crew, the equipment and the contractor's margin.
That figure is not a survey. It is calculated from the published specification. The Colorado Asphalt Pavement Association's seal coat best practices set the rate. They call for 0.10 to 0.15 gallons of mixed sealer per square yard, per coat, with two coats in all areas. Water is added at 20 to 30 percent of the concentrate. Run that through:
- 0.10 to 0.15 gal per square yard ÷ 9 = 0.011 to 0.017 gal per sq ft, per coat
- Two coats = 0.022 to 0.033 gal of mixed sealer per sq ft
- At 25% water, concentrate = 0.018 to 0.027 gal per sq ft
- Which means one gallon of concentrate covers 37 to 56 sq ft of finished, two-coat driveway
| How the sealer is bought | Price per gallon | Material cost per sq ft, two coats |
|---|---|---|
| Consumer pail, 4.75 gal at Home Depot | $7.36 | $0.13 to $0.20 |
| Consumer pail, 3 or more | $6.26 | $0.11 to $0.17 |
| Commercial 275-gallon tote | $8.76 | $0.16 to $0.23 |
| Commercial 55-gallon drum | $9.69 | $0.17 to $0.26 |
| Commercial 5-gallon pail | $21.80 | $0.39 to $0.58 |
Two things are worth noticing in that table. Bought by the tote, a contractor's sealer costs $8.76 a gallon, which is 19 to 40 percent more than the $6.26 to $7.36 a homeowner pays per gallon for a consumer pail at Home Depot. There is no bulk-buying saving on sealer to hand back to you in the quote. And commercial 5-gallon pails are the most expensive way to buy sealer by a wide margin. Nobody seals a driveway out of them.
Cross-check
Yelp, working from 286 real contractor quotes, puts sealer material at $0.10 to $0.35 per square foot. Our figure, calculated independently from the CAPA specification and current retail prices, lands at $0.13 to $0.26. Two different methods, the same answer, which is a good sign that the two-coat assumption is the right one.
Why the coverage on the pail is not the coverage you get
Label coverage figures are single-coat figures on smooth asphalt, and they overstate the real job by roughly half. A pail claiming 400 to 500 square feet covers about 190 to 280 square feet of driveway. That is what happens once you apply both coats. Henry publishes 200 to 500 square feet per 5-gallon pail depending on surface, which is honest about the spread but still describes a coat, not a job.
This is the single most common way a DIY sealcoating budget goes wrong. You buy to the label number and run out partway through the second coat. The batch you buy the next day leaves a visible lap line that cannot be blended out. Buy for two coats, and buy the extra pail.
It also quietly explains part of the price spread above. A contractor pricing off a label coverage figure is pricing a one-coat job whether they intend to or not.
How much to sealcoat a 2,000 sq ft driveway?
A 2,000 square foot driveway costs $400 to $800 to sealcoat professionally in the contractor-published figures above, and about $350 to $450 in materials to do yourself. At this size you are past the minimum charge, so area governs. Do not multiply a small-driveway rate of $1 to $2 per square foot by 2,000: that rate is built on the fixed cost of a visit.
The material side, worked through under the two-coat specification at the average application rate:
- 2,000 sq ft ÷ 9 = 222 square yards
- 222 × 0.125 gal per SY × 2 coats = 55.6 gallons of mixed sealer
- At 25% water: 55.6 ÷ 1.25 = 44.4 gallons of concentrate
- ÷ 4.75 gal per consumer pail = 9.4, so buy 10 pails
- 10 × $34.97 = $350 in sealer, or $297 at the three-or-more price
- Sand at 300 lb per 100 gallons of concentrate = 133 lb
| Line item | Do it yourself | Hire a contractor |
|---|---|---|
| Sealer, two coats | $300 to $350 | included |
| Silica sand | $20 to $40 | included |
| Crack filler | $30 to $80 | $1 to $3 per linear foot |
| Squeegee, brush, tape, gloves | $40 to $80 | — |
| Pressure washer rental, if needed | $50 to $120 per day | extra if needed, see add-ons below |
| Labor | 8 to 12 hours, two people | — |
| Total | $440 to $670 | $400 to $800 |
The result most people do not expect
At 2,000 square feet, doing it yourself saves very little. The tools are one-off, so a second sealing is cheaper, but the first one costs about what a contractor charges and takes two people a weekend. DIY wins decisively at the small end, where a $150 to $200 minimum charge buys $50 to $105 of sealer, and loses ground steadily as the driveway grows.
How much does a 5 gallon bucket of asphalt sealer cost?
A 5-gallon pail of driveway sealer costs $18 to $65 at retail in 2026, with the mainstream consumer products clustered around $30 to $40. Commercial-grade concentrate is a different market. Sold by the drum or tote it works out to $8 to $15 a gallon. A commercial 5-gallon pail can be $109.
| Sealer | Typical price | Notes |
|---|---|---|
| Budget coal tar emulsion, 5 gal | $18 to $28 | Cheapest per gallon. Banned outright in some states, see below |
| Latex-ite Ultra Shield, 4.75 gal | $34.97 | $29.72 each for three or more, The Home Depot, August 2026 |
| Premium consumer emulsion, 5 gal | $40 to $65 | Higher solids, longer stated service life |
| Commercial asphalt emulsion, 55 gal drum | about $533 | $9.69 per gallon |
| Commercial asphalt emulsion, 275 gal tote | $2,409 | $8.76 per gallon |
| Acrylic, 55 gal drum | $900 and up | $16 and up per gallon; used where coal tar is prohibited |
Coal tar is cheaper, and in some places illegal
Coal-tar sealer is the cheapest product on that table, and it is worth knowing why before you choose on price. According to the U.S. Geological Survey, coal-tar-based sealcoat typically contains 35,000 to 200,000 mg/kg of polycyclic aromatic hydrocarbons. That is about 1,000 times more than asphalt-based sealcoat, and about 100 times more than used motor oil. Coal tar and coal-tar pitch are both known human carcinogens. Sealcoat products are typically 20 to 35 percent one or the other.
New York prohibits both the sale and the application of coal-tar pavement products on driveways and parking areas under Environmental Conservation Law section 37-0119(2). Austin, Texas banned it in 2006. Sediment cores taken from Lady Bird Lake in 2012 and 2014 showed a 58 percent decrease in PAH concentrations against the pre-ban peak. Other states, counties and municipalities restrict it too, so check locally before buying. If a quote comes in well under everyone else's, ask what is in the tank.
Does spray or squeegee change the price?
Less than the number of coats does. Squeegee application is slower. In SealMaster's words it produces "increased material usage per square yard on most surfaces". More sealer and more hours both push a quote up. Spray is faster and gives a more uniform finish. CAPA accepts either method, asking only for equipment "capable of applying the required coverage rates evenly over the entire surface".
The practical difference is where each works. Squeegee pressure pushes sealer into surface voids, which matters on a porous or never-sealed driveway. Spray lays a more even film on smooth, dense asphalt. Plenty of contractors squeegee the first coat and spray the second for that reason. The tool matters less than the coat count. A single-coat quote priced as though it were two costs you far more in service life.
Crack sealing and the other add-ons
Crack sealing is the add-on most likely to appear on your invoice, at $1 to $3 per linear foot. Sealer is a surface coating roughly the thickness of a business card. It closes hairline cracks and nothing else, so anything wider has to be dealt with first or the sealcoat is decoration over a hole.
| Add-on | Typical cost | When you need it |
|---|---|---|
| Crack sealing | $1 to $3 per linear foot | Any crack from 1/4 in to 1 1/2 in wide |
| Pothole patching | $50 to $200 each | Before sealing; the patch needs 30 to 90 days to cure first |
| Pressure washing | $0.27 to $0.39 per sq ft | Heavy dirt, moss or algae the blower will not lift |
| Oil spot primer | Usually bundled | Oil and grease stains, which sealer will not bond over |
| Third coat | $40 to $120 | High-traffic areas only, per the CAPA specification |
| Excess dirt surcharge | $100 to $200 | Long-neglected surfaces |
CAPA is specific about which cracks get filled. Clear vegetation and debris to at least half an inch deep. Fill the rest with hot rubberized crack sealant, but ignore hairline cracks under 1/4 inch, the seal coat closes those on its own. Cracks over 1 1/2 inches need a hot-applied mastic or full-depth replacement instead. Our step-by-step guide to fixing cracks in an asphalt driveway covers doing that part yourself before the crew arrives. It is the one add-on most homeowners can genuinely take off the bill.
Is it worth it to seal an asphalt driveway?
It is worth it when the surface shows the distresses sealing is designed to treat, and it is money for appearance when it does not. The Asphalt Institute is unusually direct about this. Sealing is effective "to renew old asphalt surfaces that have become dry and brittle with age, to seal small surface cracks and surface voids, and to inhibit raveling". It "should be done as soon as any of these distresses are noted". The Institute gives no interval at all. It notes that a well-built low-traffic pavement "should not require sealing for approximately 2 to 5 years".
Set against the alternative, the money looks reasonable. Twenty years of sealing an 800 sq ft driveway on a four-year cycle costs less than a single resurfacing.
| Over 20 years, 800 sq ft driveway | Cost |
|---|---|
| Sealcoating every 4 years, 5 applications at $200 to $450 | $1,000 to $2,250 |
| One resurfacing / overlay at $4 to $8 per sq ft (Fixr) | $3,200 to $6,400 |
| Full replacement at $4 to $15 per sq ft (HomeGuide) | $3,200 to $12,000 |
The honest caveat is that nobody, the Asphalt Institute included, promises that sealing defers a resurfacing. What sealing demonstrably does is slow surface oxidation and keep water out of the top of the pavement. It does nothing for a failing base, and no amount of it will fix alligator cracking or a driveway that has reached the end of its life. If you are not sure which situation you are in, our guide to resurfacing versus replacement is the decision to make before you spend anything on sealer.
The other half of the answer is frequency. Sealing a sound driveway every year is a real waste of money. CAPA warns against excess application: material that ends up picked up on shoes and tires. That is what over-sealing produces. Seal when the surface shows wear. Our asphalt driveway maintenance checklist sets out what to look for, and how long an asphalt driveway lasts shows how much maintenance actually moves the lifespan.

Frequently asked questions
Professional sealcoating runs about $355 to $800 for a typical 400 square foot driveway. Fixr puts the national average at $468 in a range of $355 to $600, and HomeGuide lists $400 to $800. Some contractor-published prices run lower: about $175 to $325 for the same driveway, because many crews work to a minimum job charge of $150 to $200. Crack sealing and pressure washing are usually extra.
HomeGuide lists $1 to $2 per square foot for a 400 square foot driveway, including labor. The per-square-foot figure falls as the driveway gets larger, because the fixed cost of the visit is spread over more area: contractor-published prices for driveways over 800 square feet work out to roughly $0.20 to $0.56. Rates of $0.15 to $0.30 per square foot are commercial parking lot rates. Never scale a small-driveway rate up to a large driveway.
About $400 to $800 professionally in contractor-published figures, and about $350 to $450 in materials to do it yourself. At 2,000 square feet you are past the minimum charge, so area governs. The material works out to 222 square yards. At 0.125 gallons per square yard per coat over two coats, that is 55.6 gallons of mixed sealer, or 44.4 gallons of concentrate: ten consumer pails at roughly $35 each. Crack sealing is extra at $1 to $3 per linear foot.
$18 to $65 at retail in 2026, with mainstream consumer products clustered around $30 to $40. Latex-ite Ultra Shield sells at The Home Depot for $34.97 for a 4.75-gallon pail, or $29.72 each for three or more. Budget coal-tar emulsion runs $18 to $28. Commercial-grade concentrate is priced differently: about $9.69 per gallon by the 55-gallon drum and $8.76 by the 275-gallon tote, but $109 for a commercial 5-gallon pail.
Not relative to the alternatives, but the price you pay bears little relation to what goes on the driveway. On a typical 600 square foot driveway the sealer itself is worth $78 to $156. The rest is the visit, the crew and the equipment. Across 20 years, sealing an 800 square foot driveway every four years costs about $1,000 to $2,250 at contractor-published prices. One resurfacing costs $3,200 to $6,400 at Fixr's $4 to $8 per square foot.
It is worth it when the surface shows the distresses sealing treats, and it buys appearance when it does not. The Asphalt Institute says sealing renews surfaces that have gone dry and brittle, seals small surface cracks and voids, and inhibits raveling. It should be done as soon as any of those appear. It gives no calendar interval and notes that a well-built low-traffic driveway should not need sealing for approximately 2 to 5 years. Sealing does nothing for a failing base or alligator cracking.
Get three local quotes and compare them on specification rather than headline price. Ask each contractor how many coats they are quoting, whether crack sealing is included or extra, what their minimum charge is, and which sealer they use. Prices vary by region, and the bigger source of difference between two quotes is usually one coat versus two.
It depends on the size of the driveway, and the answer surprises people. On a small driveway where a $150 to $200 minimum charge buys about $70 of sealer, doing it yourself saves most of the bill. On a 2,000 square foot driveway, DIY materials and tools come to $440 to $670. A contractor charges $400 to $800. The first job saves very little and takes two people a weekend. Tools are one-off, so a repeat sealing is cheaper.
Mostly coat count. The Colorado Asphalt Pavement Association specifies two coats over the whole surface. A one-coat job uses half the material and less labor. It can be quoted far lower without anyone being dishonest. Other causes are the minimum charge dominating small jobs, whether crack sealing and pressure washing are included, and the type of sealer in the tank. Ask for the specification as well as the total.
Roughly 190 to 280 square feet applied as the standard two coats, against label claims that typically quote 400 to 500 square feet. Label figures describe a single thin coat on smooth asphalt. The Colorado Asphalt Pavement Association rate is 0.10 to 0.15 gallons of mixed sealer per square yard per coat. At that rate one gallon of concentrate covers 37 to 56 square feet of finished two-coat driveway. Buying to the label number is the most common reason a DIY job runs out mid-coat.
